Pressure Zone Map

A: Aqueduct Zone

R: Reservoir Zone

R1R1: Reservoir 1, Reduced 1

1. Zone A includes eight sub-zones numbered A1 through A9 (no A7 zone). All of the connections in Zone A receive water directly from the Sonoma County Water Agency (SCWA) aqueduct system. The estimated population for this zone is 109,941 which is approximately 65% of the total city population. The water enters the Santa Rosa system via a 36" Santa Rosa Aqueduct main, parallel to the tracks of the North West Pacific Railroad, a 36” main from the West via the Kawana Aqueduct and a 24” main via the Petaluma Aqueduct from the South paralleling the tracks of the North West Pacific Railroad. If a break were to occur on any one line, the remaining two would be able to feed water to the City system. The A Zone sub-zones

7

(A1 – A9) were created so if we have some type of contamination in a given area, we could send letters of notification to that localized area. These sub-zones were also created to assure good representative samples could be drawn from throughout the Aqueduct Zone. Brief descriptions of the sub-zones are below and are graphically represented on the map on page 6.

2. A1: Residential, commercial, and industrial connections located in Northwest Santa Rosa with

the South border being Guerneville Road and East border being Highway 101. This includes Sharon Park Well, a stand-by water well which is currently inactive and is not connected to our drinking water system. Coffey Park is currently being evaluated for a new water well source to replace Sharon Park Well. There are 9 dedicated sample stations in this zone.

3. A2: Residential and commercial connections, with some industrial usage. The North border is

Guerneville Road, South border is Highway 12 and East border is Highway 101. This also includes SCWA turnout # 000 which serves City property at 900 Sanford Rd. This includes Well #3 (Freeway Well) which is not connected to our drinking water system. This well is isolated by an air gap. This area includes residential and commercial connections. The City of Santa Rosa corporation yard is located in this zone as well as Finley Community Center, site of our Emergency Operations Center. There are 10 dedicated sample stations in this zone.

4. A3: Primarily residential usage, with some commercial concentrations. There have been

several large residential developments built in the last few years. The North border is Highway 12, East border is Highway 101 and South border is the City limits. Included in this zone is our Laguna Water Reclamation Facility which is served by SCWA turnout #245. The SCWA 2 inch turnout is protected by a backflow prevention device and an air gap type backflow prevention device. This zone is being evaluated for a potable water well site(s). There are 13 dedicated sample stations in this zone.

5. A4: Residential and commercial connections. This includes the Santa Rosa Junior College

campus and Kaiser Hospital. The zone is bordered by Highway 12 on the West, College Avenue and 4th Street to the South and elevated pressure zones to the East. This zone is being evaluated for a potable water well site near the rural cemetery on Franklin Avenue. There are 9 dedicated sample stations in this zone.

6. A5: Residential and commercial connections. This zone is bordered by College Ave and 4th St

to the North, Farmers Lane to the East, Highway 12 to the South and Highway 101 to the West. This sub-zone contains three domestic wells known as the Farmers Lane wells which pump directly to the Farmers Lane Water Treatment Plant (iron and manganese removal pressure vessel) located at 2260 Sonoma Avenue (Station 4). The two primary wells, Farmers #1 & #2, are active water sources with an output total of approximately 2,500 gallons per minute. Farmers treatment plant was permitted in 2005 by the California Department of Public Health as a potable water supply. The third well, Farmers #3 well has been inactivated. The treated well water is primarily pumped to the reservoir 4 zone (R-4), Bennett Valley’s reservoir 9 reduced zone (R9R1) and directly into the aqueduct 5 zone (A5). The Farmers Lane treatment plant is primarily for seasonal peak reduction during the warm months from June to November. The water wells are deep which causes the temperature to be consistently in the low 80 degree range. This zone encompasses the downtown area and includes Memorial

8

Hospital, City Hall, the State and Federal buildings. This zone is being evaluated for a potable water well site in Doyle Park. There are 8 dedicated sample stations in this zone.

7. A6: Primarily commercial connections, with residential developments, including apartments, off the main business thoroughfares. The zone is bordered on the North by Highway 12, zone 11 to the East, the City limits to the south and Highway 101 to the West. This includes Sonoma County Fairgrounds and the commercial area of Santa Rosa Avenue all the way to the Southern border with Rohnert Park. There were quite a few apartments and commercial dwellings built in this area in the last few years. There are 7 dedicated sample stations in this zone. Along Santa Rosa Avenue, there are several private water systems such as mobile home parks and motor inns.

List of other water systems along Santa Rosa Avenue:

Wayside Gardens Mobile Home Park, 2389 Santa Rosa Ave, System #4900792 Mountain View Mobile Estates, 2860 Santa Rosa Ave, System #4900798 El Portal Mobile Estates, 3010 Santa Rosa Ave, System #4900799 North Star Mobile Home Park, 3200 Santa Rosa Ave, System #4900797 El Crystal Mobile Home Park, 3280 Santa Rosa Ave, System #4900788 Western Mobile Home Park, 3309 Santa Rosa Ave, System #4900791 Days Inn, 3345 Santa Rosa Ave, System #4900815 Plaza Mobile Home Park, 3350 Santa Rosa Ave, System #4900787 Rancho Santa Rosa Mobile Home Park, 3455 Santa Rosa Ave, System #4900786 Friedman Brothers Home Center, 4055 Santa Rosa Ave, System #4900812 Todd Road Mutual Water, Santa Rosa Ave/Todd Rd, System #4901005

8. A8: Mostly residential with light commercial service. This zone is commonly referred to as

“Oakmont” and is on the Southwest side of Highway 12 about 5 miles east of downtown Santa Rosa. This area was built in the 1960’s as a residential retirement area with an age limitation for occupancy. There were quite a few new homes and some commercial dwellings built in the last few years. There are 5 dedicated sample stations in this zone.

9. A9: All residential. This small zone was developed to accommodate a 22 unit residential

development adjacent to an existing neighborhood served by the Melita Heights Mutual Water Company (System #4900551). The zone is just East of Spring Lake. There is 1 dedicated sample station in this zone.

10. Zone Reservoir 1 (R-1): Obtains water from the SCWA aqueduct turnout near Piner Rd and

Coffey Ln and transported through a 16" transmission line to Pumping Station S-1 on Fountaingrove Parkway. Reservoir R-1A and R-1B (1M gal each) fill via S-1 to pressurize Zone R-1. The connections are mostly homes, including several multi story office buildings, a large hotel, senior assisted living center and some light commercial and residential on Altruria Drive. There are 2 dedicated sample stations in this zone. The zone is home to approximately 730 people or 0.43% of the city total.

17. Zone R-3: Water from Zone R-2 is pumped by Station S-3 (new pumps have been installed and the new pumping capacity is: 1 pump 600 G.P.M., 2 pumps 1,200 G.P.M.) to Reservoir R-3 (capacity 500 K gal). This reservoir pressurizes Zone R-3 which is upscale residential large lots. There are 2 dedicated sample stations in this zone with an estimated population of 1362 (0.81% of total).

18. Zone R-4: Water is pumped to Zone R-4 by Pump Station S-4 from the SCWA aqueduct or the

City of Santa Rosa Farmers Lane Water Treatment Plant. Reservoirs that serve this zone are Aqueduct Reservoir 1 and 2 (AR-1 and AR-2) (2.5M gal each), R-4A (1M gal) and R-4B (2M gal). AR-1 and AR-2 are new reservoirs (2008) and were designed for additional water supply during emergencies with the capability to supply the lower “aqueduct zones” with water pressure should there be a disconnection from SCWA supplies. This zone is nearly all residential in the Northeast area. There are 5 dedicated sample stations in this zone with an estimated population of 2808 (1.66% of total).

19. Zone R-4R1: Reduced pressure feed from the reservoirs in Zone R-4. The Leete stand-by well

(300 G.P.M.) is located in this zone. In addition to serving Zone R-4 if necessary, the water from Leete Well could be routed to sub zones A-1, A-2, A-4 and A-5 in cases of extreme need. As with the other wells in the system, this well has not been in service for over ten years, but it is flushed each year and on a compliance cycle from CDPH. This zone is mostly residential with school, churches and a fire station. There are 2 dedicated sample stations in this zone with an estimated population of 1119 (0.66% of total).

20. Zone R-4R2: This is also reduced pressure from Zone R-4. This zone includes Sutter Hospital

and the other County Facilities located on Chanate Road. The other connections are residential including a senior housing complex. There is 1 dedicated sample station in this zone with an estimated population of 713 (0.42% of total).

21. Zone R-4R3: Service is provided by routing water from R-4 through pressure reducing valves

but, due to pressure fluctuations, a small variable speed pump station was installed at Murdock Drive to pump aqueduct water from zone A4. For the most part, the Murdock pump station supplies this zone with R-4 zone as back-up. All connections in this zone are residential. There are 2 dedicated sample stations in this zone with an estimated population of 2049 (1.21% of total).

22. Zone R-4R4: Water from Zone R-4 is run through pressure reducing valves to this zone. This

zone contains 31 connections located in a single condominium development on Alice Street, behind the Flamingo Hotel. There is 1 dedicated sample station in this zone with an estimated population of 65 (0.04% of total).

23. Zone R-5: The R-5 area is a subdivision in Fountaingrove known as Skyfarm. This reservoir,

(300K gallons), is elevated 75 feet from ground level to the top of the tank. An earthquake survey was performed in 1998 and determined R-5 could be susceptible to damage. The reservoir is not filled completely but relies on a 3,000 GPM fire pump if a fire emergency occurs. Pump station (S-5) feeds the tank from R-2B reservoir site. This area has been developed for residential use only with new construction taking place. The station has been upgraded with one 3,000 GPM fire pump, two new 300 GPM pumps and a new pump station generator. There are 2 dedicated sample stations in this zone with an estimated population of 875 (0.52% of total).

11

24. Zone R-6: This zone is fed from the SCWA aqueduct by Pump Station S-6 located at the SCWA’s Sonoma Booster pump station on Montgomery Drive. The water is pumped to Reservoir R-6 (4M gal), and serves the floor of the entire Rincon Valley area and Montgomery Drive to Yulupa Avenue to the Hwy 12 area. This area has residential and commercial connections. There are 9 dedicated sample stations in this zone with an estimated population of 12418 (7.35% of total).

25. Zone R-6R1: This zone is a recent addition due to inherently low water pressure in the Eastern

section of the A5 zone. Isolation valves were installed along Farmers Lane to extend R-6 to this area with the addition of pressure regulating valves raising the old A5 zone pressure by 15 psi. R-6R1 is bordered by Highway 12 to the North, Summerfield Road to the East, Hoen Avenue to the South and Farmers Lane to the West. Two stand-by wells are located in this zone on Carley Road and they have a total output of 1,200 G.P.M. These wells are valved in a way that allows usage of this water in either R-6R1, Zones R-9 or R-10 using Pump Station #9 through the 18" transmission line. The two wells are being used for non-potable uses as a supplemental water supply to fill Lake Ralphine in Howarth Park and to irrigate the recreational fields at Slater Junior High School and Peter Springs Park. There are 6 dedicated sample stations in this zone with an estimated population of 6977 (4.13% of total).

26. Zone R-7: This zone is fed from Station 7 at Calistoga Road and Monte Verde Drive.

Reservoir R-7 has a capacity (2M gal). This zone is mostly residential with commercial areas along the main thoroughfares. In an emergency, water can be obtained from reservoirs R-4A and R-4B by way of a cross valley transmission line and consequently it can be reversed with water pumped from Station 7 to R-4A and R-4B. There are 7 dedicated sample stations in this zone with an estimated population of 6125 (3.63% of total).

27. Zone R-8: This zone is fed from Station 8 at Mountain Hawk and Sailing Hawk Dr Station 8

pulls water from Reservoir R-7 to fill Reservoir R-8 (750K gal). This zone is just to the East of zone R-7 and is all residential. There are 2 dedicated sample stations in this zone with an estimated population of 97 (0.06% of total).

28. Zone R-9: A SCWA aqueduct turnout at Sonoma and Summerfield directly supplies the Pump

Station S-9 at Summerfield Drive and Carissa Avenue. Zone R-9 is served by Reservoirs R-9A (2M gal), R-9B (2M gal) and R-9C (1M gal). This area feeds most of the residential and commercial users in the Bennett Valley area. We also have a variable drive pump at Station 4 that pumps water into this Bennett Valley area at a rate of up to 1,600 GPM. This inner-tie is located at Hammond and Hoen Avenue. There are 3 dedicated sample stations in this zone with an estimated population of 2912 (1.72% of total).

29. Zone R-9R: Water from the above reservoirs (R-9 A, B & C) can flow through reduced

pressure valves to serve Zone R-9R though most pressure is sustained by the variable drive pump at Station 4. This zone is 80% residential and 20% commercial. There are 9 dedicated sample stations in this zone with an estimated population of 11539 (6.83% of total).

30. Zone R-10: Pump Station R-10 receives water from Reservoirs R-9A, B & C to fill Reservoir R-

10 (200 K gal) which serves Zone R-10. This area is 100% residential. There is 1 dedicated sample station in this zone with an estimated population of 175 (0.10% of total).

31. Zone R-11: Pumping Station R-11, on Kawana Springs Road, pulls directly from the SCWA

Kawana aqueduct below the Kawana Tanks. The Reservoir R-11 (1.15M gal) is just below the Holland Heights neighborhood (Holland Heights Mutual Water Company #4900548) and supplies the new residential neighborhood just south of the Sonoma County Fairgrounds. This zone is all residential. There is 1 dedicated sample station in this zone with an estimated population of 503 (0.30% of total).

12

32. Zone R-12: SCWA water is pumped from the aqueduct via Pumping Station S-12 to Reservoirs R-12A (500K gal) and R-12B (1M gal). Pressure reducing valves could be used to back feed water from Reservoirs R-12A and R-12B and to Sub-zone A-8 for fire protection and domestic use, if needed. There are 5 dedicated sample stations in this zone with an estimated population of 4426 (2.62% of total).

33. Zone R-13: Pumping Station S-13 pumps SCWA water to Reservoir R-13 (100K gal). A

permanent generator has been installed at this pump station. This zone is all residential. Of the three new pumps at S-13, one is 400 GPM and two are 750 GPM. There is 1 dedicated sample station in this zone with an estimated population of 104 (0.06% of total).

34. Zone R-13R1: Water from Reservoir R-13 back feeds through pressure reducing valves and serves this all residential zone. There is 1 dedicated sample station in this zone with an estimated population of 42 (0.02% of total).

35. Zone R-14: Pumping Station S-14 also pumps water to Reservoir R-14 (100K gal) which

back feeds to this zone. A permanent generator has been installed at this pump station. This zone is also 100% residential. There are 2 dedicated sample stations in this zone with an estimated population of 204 (0.12% of total).

36. Zone R-14R1: Water from Reservoir R-14 back feeds through pressure reducing valves

and serves this all residential zone. There is 1 dedicated sample station in this zone with an estimated population of 65 (0.04% of total).

37. Zone R-15: This zone serves single-family residences and irrigation accounts in the west

Oakmont area. This zone was originally designed to use water from the SCWA aqueduct which parallels Hwy 12 and pump it into a hydropneumatic tank. The zone is now operated as a pressure sustaining pump station. Water is transmitted to a booster pump where pressure is maintained so the highest elevation is 40 P.S.I. and at the lowest elevation the pressure is 80 P.S.I. The area is served by two variable drive pumps with 180 G.P.M. maximum flow, or 360 G.P.M. with two pumps operating. These are pumps that function both independently and concurrently. In addition, a standby emergency generator and automatic transfer switch can provide 1,580 G.P.M. on demand for fire protection. A pumper connection has been built to accommodate manual connection to an emergency pumper, allowing pumping from the low-level system at Stone Bridge area and at pump station 15. There is 1 dedicated sample station in this zone with an estimated population of 55 (0.03% of total).

38. Zone R-16: This zone serves 31 connections in residential neighborhoods along

Fountain Grove Parkway, Reservoir 16 (225K gal) is directly fed from Station #16, which is located at R-4B. At the R-16 site there is pump station S-17, which draws out of R-16 and pumps into R-17. All pumps are 750 GPM. There is 1 dedicated sample station in this zone with an estimated population of 101 (0.06% of total).

39. Zone R-17: This zone serves residential neighborhoods along Fountaingrove Parkway.

R-17 (750K gal) is located on Newgate Court off Fountaingrove Parkway. Reservoir 17 is served by Station 17 and can also get water from the Station 18, which will take water from R-3 on the same site. This zone is all residential. All pumps are 750 GPM. There is 1 dedicated sample station in this zone with an estimated population of 1213 (0.72% of total).

40. Zone R-17R1: Serves 83 residential connections. This zone is off Fountaingrove Parkway and Hadley Hill Dr. There is 1 dedicated sample station in this zone with an estimated population of 269 (0.16% of total).

Ground Water Rule Special Section: Triggered Source Water Monitoring Plan Identification of Which Wells Contribute to each TCR Sample Site The City of Santa Rosa is divided into 31 reservoir pressure zones and 9 aqueduct sampling zones. In 2005, the Utilities Department converted two stand-by water wells to “active” status to produce a supplemental water supply. The water supply wells generally operate from June to November of each year to support higher summertime irrigation use. The two production wells pump raw water to a manganese /greensand filter prior to introduction into the water distribution system. Sodium Hypochlorite is used as an oxidizer in the treatment process along with providing a measurable distribution system chlorine residual. Due to the immediate introduction of the treated well water into the water distribution system the chlorine contact time is insufficient to provide a calculated 4-log removal of viruses. Since 4-log removal is not attainable, this triggered source monitoring plan will implement source monitoring if a positive bacteria sample is detected at one of the dedicated water sampling stations identified in this plan.

Santa Rosa Wells Representative of Each TCR Site The two water supply wells that are located on Farmers Lane near Sonoma Avenue are capable of producing 3 MGD and rely on three alternative pumping plans to ensure the water is consistently absorbed in the distribution system. The GWR stipulated that, if 4-log removal is not achievable, then, a positive coliform detection at a Water Sample Station (WSS) served by the well will trigger source monitoring. Attachment 2 of this document lists the WSS and identifies in highlighted script those stations that will trigger source monitoring with a positive coliform result.

1. Pumping to Bennett Valley (R9R1): Bennett Valley zone is the main recipient of the treated well water from Farmers Lane wells. There is a demand sensing pump providing well water to this zone. During the overnight hours demand is minimal. There are seven TCR sample stations for this zone:

a. WSS072 b. WSS074 c. WSS101 d. WSS018 e. WSS019 f. WSS020 g. WSS023

2. Pumping to the Downtown zone (A-4&5): These two zones are very similar to the Bennett Valley zone because there is a considerable residential component. This zone is unique because well water is pumped from the Farmers Lane wells into water mains that contain Sonoma County Water Agency (SCWA) purchased water. The SCWA distributes water through “turn-outs” or metered taps to provide consistent pressure to the Santa Rosa Plain. The Farmers Lane well water is pumped into these zones at a pressure slightly higher and it displaces the SCWA water while closing the nearest turnouts. The Farmers Lane wells have a high level of entrained air and we are able to differentiate our well water from SCWA

water based on evidence of entrained air at water sample stations. Based on evidence of entrained air, these TCR water sample stations are identified as being influenced by the Farmers Lane wells:

a. WSS063 b. WSS064 c. WSS084 d. WSS086 e. WSS085 f. WSS076 g. WSS071 h. WSS044 i. WSS046 j. WSS088 k. WSS087

3. Pumping to Reservoir 4, 16 and 17

zones (R 4, 16, & 17): During the overnight hours, the pumping regime changes from supplying residential and commercial zones to filling reservoirs on the hills to the north of the Farmers Lane wells. These zones will mainly receive only Farmers Lane well water. The total volume of reservoir storage is 3.5 MG terraced from a level of 532 feet to 894 feet.

IMPORTANT NOTICE REGARDING ANY POSITIVE TOTAL COLIFORM SAMPLE

The Sonoma County Water Agency (SCWA) is our wholesale water supplier and derives their water through wells along the Russian river at Mirabel and Wohler Roads near Forestville. Although they meet the requirements of the Ground Water Rule for 4-log removal of viruses, they still want to be notified by any of their contractor agencies if they have a total coliform positive in their system. The procedure for notifying the SCWA of a positive total coliform sample is to contact the 24 hour operations desk at (707) 523-1070. The duty operator will enter the details of your report into the log and contact an Operations Coordinator to evaluate any trends or operational changes based on the information. Please include in your report:

• Sample date and time • Sample location • Sample results • Sample Chlorine residual • Contact name and number for further questions

Sample Collection Procedures & Integrity of Sample

All Samples

(1) Obtain prepared sample bottles from the contract analytical lab or other appropriate vendor. These prepared bottles will typically contain specific preservatives for each material to be analyzed. No sample bottles shall be rinsed prior to collection of samples.

(2) Label with (a) Date, (b) Time, (c) Sample Location or ID #, (d) Type of Sample, and (e) "City of Santa Rosa."

(3) Follow specific sample collection procedures identified (below). (4) Complete laboratory or City of Santa Rosa Chain of Custody form and retain

a copy for your records. (5) Refrigerate sample and deliver to laboratory.

Bacteriological Samples

(1) Follow the instructions on attachment 3: “Bacteriological Sampling Procedure" to preserve the integrity of the sample.

General Mineral, General Physical, or Radioactivity

(1) These samples do not require any special handling other than filling the laboratory-provided containers with cold water from the sample location.

Inorganic Chemical

(1) Fill sample container with cold water. Do not overfill or rinse container.

Nitrate as NO3

(1) Fill sample container with cold water. Do not overfill or rinse container. (2) The maximum contaminant level for nitrate is 45 mg/L. Nitrate samples are

required annually for Farmers 1 and 2. If a sample result from a well is greater than or equal to 22 mg/L (50% of the MCL) then additional sampling will be required. (22CCR 64432.1.(a)(2)).

(3) Sample must be analyzed within 48 hours. Use overnight service when mailing to laboratory.

Volatile Organics

(1) Follow the instructions on attachment 4: "Filling VOA Vials - Procedure" to preserve the integrity of the sample.

20

Bacteriological Re-Sampling

In the event that an initial weekly sample is identified present or positive for total coliform by the laboratory, the Water Quality Supervisor will:

(1) Immediately notify Water Quality or Weekend Operations staff. (2) Collect three separate repeat samples for each total coliform-positive sample

within 24 hours of laboratory notification. The repeat sample set shall consist of: (i) One repeat sample shall be collected from the sampling tap where the

original coliform-positive sample was taken. (ii) One repeat sample shall be collected within 5 services upstream from the

original total coliform-positive site. (iii) One repeat sample shall be collected within 5 services downstream from

the original total coliform-positive site. (iv) One sample from each well to comply with (4) below if applicable. Note: If repeat sample collection is not possible within 24 hours, the Department of Public Health must be notified within 24 hours. If the original sample location has no upstream or downstream location, two samples shall be taken at the original location in addition to the existing upstream or downstream location.

(3) Label the repeat samples as "'REPEAT,' date, location, & City of Santa Rosa" and submit to the laboratory on the same day the samples were taken.

(4) If the positive coliform sample corresponds to one of the highlighted water sample station located in attachment 2 during the operation of the Farmers Lane water treatment plant, then an E. coli sample must be taken of the raw water from each well.

21

Procedure for Additional Total Coliform-Positive Repeat Samples

In the event that one of the three samples in the first repeat sample set is total coliform-positive, but not fecal coliform-positive or E. Coli positive, the Water Quality Supervisor or other responsible party will:

(1) Complete a second repeat sample set in the same locations within 24 hours

of being notified of the positive repeat sample result. The City of Santa Rosa will continue to repeat the sampling process until either no coliforms are detected in one complete repeat sample set or the City of Santa Rosa determines that the MCL for total coliforms specified in 22CCR 64426(a)(1) has been exceeded and notifies the California Department of Public Health (CDPH). To exceed the MCL for total coliforms, we must exceed 5.0% of the ROUTINE/REPEAT samples for the month (7 samples or above).

(2) If the City of Santa Rosa has a total coliform-positive routine sample followed by two total coliform-positive repeat samples in the repeat sample set, the Water Quality Supervisor shall notify the CDPH by the end of the day on which the system is notified of the test result or the system determines that it has exceeded the MCL. If the CDPH office is closed, notification shall be within 24 hours. See 22CCR 64426(b)(2) for submission information to CDPH.

23

Notification Procedure for After Hours & Weekends (for 1st or 2nd Positive Repeat Samples)

Total Coliform In the event that the laboratory notifies Water Quality staff of a total coliform positive sample or repeat total coliform sample after hours or on weekends, the responsible party will request the following information:

(a) Date & time the positive sample was taken, (b) location where positive sample was taken, (c) chlorine residual results for the positive location, and (d) Other circumstances pertinent to the positive sample.

Water Quality or Weekend Operations staff will follow procedures outlined above.

Procedure for Positive Fecal Coliform or E. Coli Bacteriological Samples

A fecal coliform or E. coli positive routine sample shall be treated the same as a coliform positive as listed in Bacteriological Re-Sampling on page 20. If a repeat sample is total coliform positive then this is an acute MCL violation.

• The violation must be reported to the state no later than the end of the next

business day after the system learns of the violation. • The public must be notified within 24 hours after the system learn of the violation.

If the routine sample was total coliform positive, and one of the three (3) resamples were fecal coliform or E. coli positive then this is also an acute MCL violation. • The violation must be reported to the state no later than the end of the next

business day after the system learns of the violation. • The public must be notified within 24 hours after the system learn of the violation. In the event that any bacteriological sample is positive for fecal coliform or E. Coli, laboratory personnel will:

(1) Immediately contact a designated staff member in the "Emergency Notification

Plan" (2) Follow Emergency Procedures below.

Reporting Requirements

(1) Monthly Bacteriological Reports

The laboratory shall prepare and submit this report as follows:

Water Quality Supervisor no later than the 10th of the following month California Department of Public Health no later than the 10th of the

following month

24

Emergency Procedure

The City of Santa Rosa Emergency Contact will take the following actions:

25

If any bacteriological sample returns positive for fecal coliform or E. Coli,

contact a CDPH representative immediately, and: The Water Utility Emergency Response Manager (WUERM) shall be notified

and informed of the exact location of the positive sample site. A field and records inspection will be conducted to try to resolve the reason for the positive sample. Additional sampling and system flushing will be conducted. Shock chlorination and flushing of the system will most likely occur. A health advisory will be issued within 24 hours or as soon as practical to alert all water users that there is a health risk associated with the water supply. The City of Santa Rosa Police Department’s CityWatch Community Notification System will be activated to notify specific pressure zone residents if applicable.

POTABLE WATER HAULING SAMPLE SCHEDULE:

One bacteria sample of hauled water every 30 days. Water shall not be stored in the vehicle for a period greater than one week.

All testing must be done by a California laboratory that has been certified for testing water or by a laboratory certified by the United States Environmental Protection Agency (USEPA). For a list of certified laboratories, please contact the California Environmental Laboratory Accreditation Program (ELAP) at (510 620-3155 or http://www.cdph.ca.gov/certlic/labs/Pages/ELAP.aspx. Testing done by a laboratory approved by the primary enforcement authority in states which have been granted primacy by the USEPA is also acceptable pursuant to H&SC 111165. Take four samples and send all four samples to the testing laboratory. The laboratory will randomly select one of the four samples to test for coliforms. The laboratory may use the presence/absence (P&A) test for the coliform analysis. Only negative (absence) test data are acceptable. If a sample tests positive (presence), you must resample the water (i.e., four random samples) within 24 hours and test using the multiple tube-fermentation method. If the test data show that the water contains more than 2.2 most probable numbers (MPN)/100 ml, you must immediately stop distributing the water; notify the FDB Licensing Desk; investigate the cause of the problem; take corrective actions and resample/test the water. You must not resume the distribution of water until the test shows that the water contains total coliforms of less than 2.2 MPN/100 ml. Pursuant to H&SC Section 111155, FDB may ask you to test for other contaminant(s) if FDB suspects the substance(s) may be present in the water.

Attachment 3 Bacteriological Sampling Procedure

1) Turn on the sample station and allow to flush for several minutes or until a representative sample from the main can be assured. While the station is flushing, label the container. All sample containers should be properly labeled with utility name, sample location, parameter to be analyzed, preservative, if any, date, time and sampler name. 2) Adjust to a moderate flow which will allow the container to be filled without splashing. 3) Allow sample tap to flush for another minute after adjusting flow. This will allow any material dislodged to flush out. 4) Remove the cap, taking care to not allow the cap or the container to become contaminated. Do not set the cap down while filling the container.

34

5) Do not adjust the flow while taking the sample. 6) Fill the container to the desired level without splashing. Do not rise or overfill the container. 7) Cap the container securely. 8) Shake the container to mix any preservative. Affix the label and place into the ice chest (4ºC) for transport to the lab.

9) Turn off the sample station and finish filling out the chain of custody.

35

Section IV – Sample Transport and Receiving The samples must be protected from contamination or temperature changes on the way to the laboratory. Correct protocol upon delivery is also important to keep the samples valid. 1. Time and Temperature All samples should be stored in a cooler during transport to the laboratory (4ºC). Purchase coolers that accommodate “blue ice” packs neatly at the bottom or in the lid. Never use regular ice when collecting bacteriological samples. The melted ice could easily splash onto the sample containers and possibly contaminate them. Per Standard Methods, 20th edition, samples for coliform bacteria and heterotrophic bacteria analysis should be brought to the laboratory within six hours of collection. Upon arrival at the laboratory, the samples should be refrigerated and then set up within two hours. If these times are not realistic, as when mailing samples to a laboratory, the time elapsing between taking the sample and laboratory set-up should not exceed thirty hours. If these times are still impossible to achieve, a call to your State Public Health representative is in order.

Attachment 4 Sampling Procedure for Volatile Organic Compounds

1) Flush the sample station to ensure that the sample will be representative of the source. While the tap is flushing, label the container. All sample containers should be properly labeled with utility name, sample location, parameter to be analyzed, preservative, if any, date, time and sampler name. 2) Adjust the flow so that the vial may be slowly filled without splashing or aerating the sample. Excessive bubbling of the sample may result in the loss of the volatile organic compounds of interest. Do not adjust flow while filling. 3) Remove the cap. Be careful not to set the cap down or contaminate the inside of cap or vial. Tip the vial slightly and place it under the stream of water so the water flows down the inside wall. If the container contains a preservative, be careful to not rinse it out. 4) Slowly bring the bottle to an upright position as it fills. Slightly overfill the vial so that the level of the water in the vial appears as a convex meniscus slightly protruding over the top of the vial.

37

5) The correctly filled vial with the “convex meniscus” is on the right. 6) Carefully add any additional preservative which may be required, such as hydrochloric acid. If using an acid preservative, use caution and the appropriate personal protection equipment (PPE) such as safety glasses or gloves. Immediately rinse off any acid that comes in contact with the skin or clothing.

7) Carefully replace the cap, tighten and invert to check for bubbles. 8) This is an example of unacceptable headspace. If a bubble is present, remove the cap and top off the vial.

9) The vial may be “topped-off” by pouring water from the cap into the vial. Cap the vial and check again. Repeat as necessary to ensure that there is no “headspace” in the vial.

10) Place the vials into an ice chest to transport back to the lab for analysis.

38

11) Turn off the ball valve and finish filling out the chain of custody. If sampling from a surface source, use a bailer. Alternatively, remove the cap with one hand and place the vial under the surface of the water, moving the vial forward, with the opening of the vial or container, as the leading edge. This minimizes any contamination which may be introduced from the sampler’s hands. Immediately after sampling and addition of preservatives, place the VOC’s into a resealable plastic bag to prevent contamination. Then place them into a bubble-type bag or sleeve to prevent breakage and finally into an ice chest containing blue-ice type block. Keep at 4º C. Sampling for Synthetic Organic Compounds (SOCs) & Non-Volatile Organic Chemicals The sampling procedure for SOCs and nonvolatile organic chemicals is similar to the procedure for VOCs. The differences are with respect to the bottle types, preservatives and the fact that a slight headspace in the container is allowed. Again, the type of container and preservative(s) are specific for each particular test. Do not rinse the container before filing. Overfilling may flush the preservative out of the container. Many samples for SOCs only require storage at 4º C to preserve them. Others may require one or more preservatives. If you have any questions regarding the appropriate preservative consult with your laboratory.
