1.0 Introduction

The alternate water supply system (AWSS) was installed in 1998 by Indian Health Services. TheU. S. Department of Energy (DOE) provided $800,000 in funding, which included 25 percent ofthe cost of a new 1,000,000-gallon storage tank. As a component of the institutional controls (IC)for the Riverton, Wyoming, Processing Site, the AWSS is intended to supply drinking water toresidents within the IC boundary in lieu of drinking groundwater that could be potentiallyimpacted by the contaminated shallow aquifer. The AWSS is an addition to an existing systemoperated by the Northern Arapaho Utility Organization (NAUO) and consists of 8.5 miles oftransmission pipeline running from the 1,000,000-gallon tank. Figure 1 shows the layout of theAWSS and the associated monitoring locations.

2.0 Background

Elevated concentrations of radionuclides were identified in the AWSS in 2002 (Babits 2003),and these results were confirmed by DOE in 2004 (DOE 2005). In response to these findings,DOE funded an independent analysis of the AWSS to determine, in part, the source of theelevated radionuclides and to make recommendations of how to 'reduce the radionuclideconcentrations to acceptable levels. Conclusions of the independent analysis (ASCG 2005)included:

The source of radionuclides in the system is from the source well, which has naturallyoccurring concentrations below Federal drinking water standards..

Radionuclides in the system are being concentrated by sediment accumulation in stagnantportions of the system and/or biofilm capture.

A flushing program should be implemented as a first step to reduce the radionuclideconcentrations.

In response to the conclusions of the independent analysis, DOE instituted a 2-year flushing andmonitoring program to determine if periodic, unidirectional flushing of the system would reduceradionuclide concentrations to acceptable levels. The flushing and monitoring program wasconducted according to the Alternate Water Supply System Flushing Work Plan Riverton,Wyoming, Processing Site (DOE 2006). This work plan provided a specific procedure forconducting a unidirectional flush of the system as recommended by ASCG Inc. and the U.S.Environmental Protection Agency (EPA) (ASCG 2005).

3.0 Purpose and Scope

The purpose of this report is to provide the results of the 2-year flushing and monitoring programfor the AWSS as a method to reduce radionuclide concentrations within the system. This reportalso provides results of soil testing conducted adjacent to a portion of the AWSS water line toassess potential impacts from the nearby sulfuric acid plant. The flushing and monitoringprogram was a collaborative effort between the DOE, the Wind River Environmental QualityCommission (WREQC), and NAUO.

4.0 Monitoring Results

4.1 Soil Testing

Soil sampling was conducted adjacent to portions of the water line downgradient of the sulfuricacid plant to determine if historic acid leaks at the sulfuric acid plant have impacted the soilsadjacent to the line. Measurements of pH were attempted at 0, 2, and 4 feet (ft) below groundsurface at three locations (0831, 0832, and 0833 [Figure 1]). A pH of less than 6.0 standard unitswas used as a criterion to determine if soils were impacted. As shown in Table 1, measurementsranged from 8.0 to 9.2, which indicate no impact to the soils adjacent to the water line fromhistoric sulfuric acid spills at the plant.

4.2 Hydrant Flow Monitoring

Monitoring of flow during each hydrant flush wafs required to ensure the calculated water volumeof each section of pipe was removed. Hydrant locations are shown in Figure 1. Flow meters wereinstalled at each hydrant during flushing to measure the volume of water flushed.from the pipe.Water volume removed during each flush is shown in Table 2. Volume measurements also wereused to calculate the velocity of the water moving through the pipe. Velocity data was used todetermine if water movement within the pipeline was sufficient to remove sediment and debris,and to scour biofilm from the inside of the pipe. According to the independent'analysis(ASCG 2005), flushing velocities of 2 to 3 feet per second (ft/s) are needed to remove' sedimentand loosely attached particles, while flushing velocities of greater than 5 ft/s are required to scourand remove build-up of biofilm and material adhering to the wall of the pipe. Average velocitiesmeasured during the flushing program (Table 2) ranged from 3.06 to 6.48 ft/s with an averagevelocity of 4.83 ft/s, which should remove sediment and loosely attached particles and, insections of the pipeline, remove adhered materiil and biofilm.

4.3 Analytical Results

4.3.1 Hydrants

Hydrant locations monitored during the flushing program are shown in Figure 1. This includesfour locations inside the IC boundary (0819, 0820, 0821, and 0834), and three locations outsidethe IC boundary (0818, 0829, and 0830). In addition, monitoring was conducted at one hydrantlocated in an older portion of the water system located at the Beaver Creek subdivision (0835).Samples collected from hydrant locations (Figure 1) were analyzed for radium-226, radium-228,and uranium throughout the 2-year flushing program. Gross alpha and gross beta analyses wereadded after the start of the program at the request of WREQC in response to the highconcentrations of these analytes prior to the start of the flushing program. In addition, fieldmeasurements of pH, specific conductance, temperature, turbidity, dissolved oxygen, oxidation-reduction potential, and residual chlorine were made at each location. DOE analytical resultsfrom hydrant locations are presented in Appendix A.

Samples collected from some hydrant locations prior to the start of the flushing program hadelevated concentrations of radionuclides including gross alpha, gross beta, radium-226, andradium-228. EPA Safe Drinking Water Act standards for combined radium-226+228(5 picocuries per liter [pCi/L]) and gross alpha (15 pCi/L) were exceeded at several locations.Since the start of the flushing program in May 2006, concentrations have been reduced toacceptable levels (with one exception); as shown in Table 3 and Figures 2, 3, and 4. Table 3compares statistics of pre-flushing program results with statistics of flushing program results,while Figures 2, 3, and 4 compare preflushing program sample concentrations withconcentrations of samples collected after flushing (end-of-flush sample - see section 4.3). Onesample collected during the flushing program from. hydrant 0820 had a gross alpha concentration(16.9 pCi/L) from a 5-minute sample that exceeded the standard (15 pCi/L); however, thisconcentration was from the March 2007 flushing event, which was 9 months since the previousflush. Flushing frequency is discussed in detail in Section 4.3.

Figure 4. A WSS Radium Concentrations

Uranium concentrations in samples collected from hydrant locations have been low prior to andduring the flushing program and typically two to three orders of magnitude below the EPAdrinking water standard of 0.03 milligrams per liter (mg/L) (Table 3).

One hydrant in the Beaver Creek subdivision (0835) was sampled without flushing. Results fromthis location showed concentrations of gross alpha, radium-226 + 228, and uranium were belowtheir respective EPA drinking water standard, and gross beta concentrations were less than9 pCi/L. The maximum radium-226+228 concentration from this location was 3.2 pCi/L.

4.3.2 Domestic Taps

Samples collected from domestic tap locations (Figure 1) were analyzed for radium-226,radium-228, and uranium throughout the 2-year flushing program. Gross alpha and gross betaanalyses were added after the: start of the program at the request of WREQC. In addition, fieldmeasurements of pH, specific conductance, temperature, turbidity, dissolved oxygen, oxidation-reduction potential, and residual chlorine were made at each location. DOE analytical resultsfrom domestic tap locations are presented in Appendix B.

As shown in Table 4, constituent concentrations in samples collected from domestic taps prior tothe flushing program were low and comparable to concentrations measured during the flushingprogram. Flushing activities did not affect water quality at the domestic taps; no standards wereexceeded at any domestic tap location indicating no adverse impacts to the potable water in theAWSS.

4.4 Flushing Frequency Analysis

Flushing and monitoring of hydrants was conducted on a variable frequency to determine theoptimal time between flushing events. Flushing and monitoring events were initially planned tooccur in June and November; however, maintenance problems resulted in delaying theNovember 2006 flushing and monitoring event until March 2007. This resulted in flushing andmonitoring events conducted in June 2006 and March, June, and November 2007. Monitoringonly events (no flushing) were conducted between flushing events in August 2006 andAugust 2007 to determine if more frequent flushing was needed.

Two samples were collected at each hydrant during flushing. The first sample was collected5 minutes into the flush to measure the potential highest concentrations after the flushing processhas had time to dislodge and mobilize contaminants. The second sample was collected at the endof the flush to determine the effectiveness of the flushing. In addition, 5-minute samples only (noflushing and end-of-flush sample) were collected in August as an intermediate check betweenflushing events. Results are presented in Table 5.

ITo determine if radionuclides had concentrated between flushing events, end-of-flush sampleresults were compared to the 5-minute sample results from the Subsequent flushing event todetermine if radionuclides were concentrating between flushes. To determine the optimalflushing frequency, three time periods were assessed: (1) 2 to 3 months, (2) 5 months, and(3) 9 months.

In the 2- to 3-month time periods (June 2006 end of flush to August 2006, March 2007 end offlush to June 2007 5-minute, June 2007 end of flush to August 2007), concentrations ofradionuclides increased slightly in some cases, but concentrations were low and below standards,indicating no significant concentration of radionuclides during this period. In the 5-month period'(June 2007 end of flush to. November 2007 5-minute), concentrations of radionuclides were Igenerally comparable with some slight increases and some slight decreases in concentrations; allconcentrations were below applicable standards, indicating no significant concentration of 1radionuclides during the 5-month period.

Results from the 9-month period (June 2006 end of flush to March 2007 5-minute), however,indicate an increase and concentration of radionuclides. As shown in Table 5, radium-226+228concentrations from locations 0818 and 0820 went from below detection in the June 2006 end-of-flush sample to above detection in the March 2007 5-minute sample; elevated and significant 3(above the gross alpha standard) concentrations of gross alpha and gross beta were measured inthe March 2007 5-minute sample. In addition, concentrations of radium-226+228, gross alpha,and gross beta decreased significantly between the March 2007 5-minute sample and theMarch 2007 end-of-flush sample.

5.0 Conclusions

Results from this 2-year study prove that a unidirectional flushing program is effective incontrolling radionuclide buildup in the alternate water supply system. Measurements of pH insoils adjacent to a portion AWSS water line indicate no impact to soils from historic acid spills atthe nearby sulfuric acid plant. Average flushing velocities measured during the flushing programiare capable of removing sediment and loosely attached particles accumulated in the system and,in sections of the pipeline, remove adhered material and biofilm. Comparison of radionuclideconcentrations in samples collected from hydrant locations prior to the flushing program withsample concentrations during the flushing program indicate a reduction of radionuclideconcentrations to acceptable levels and below applicable standards. Radionuclide concentrationsin samples collected from domestic taps have been low and below standards prior to or during >1flushing activities. Analysis of flushing frequency indicates that concentrations of radionuclidesincrease with a 9-month interval between flushing events, but no significant difference isdiscernable between 2-month, 3-month, and 5-month flushing intervals; therefore, unidirectional Iflushing on a 6-month interval is optimal to maintain radionuclide concentrations in the system atacceptable levels. Details of a unidirectional flushing program based on the recent flushing iprogram and the results of this report can be used to enhance NAUO's current operation andmaintenance procedures.
