1.0 Introduction

Kimley-Horn and Associates, Inc. (Kimley-Horn) was retained on behalf of Scannell Properties #252, LLC

to prepare this Landfill Stabilization Assessment Report (SAR) for the closed Class III Former Landhill

Landfill in St. Petersburg, Florida (Figure 1). This report has been prepared in accordance with Chapter

62-701 and is as part of the ongoing semi-annual groundwater monitoring that is required in Permit No.

69710-008-SF/14. Previous SAR reports were prepared by others and provided to the Florida Department

of Environmental Protection (FDEP) in three sub-reports:

1. Landfill Gas Generation and Migration

2. Groundwater and Surface Water Quality

3. Landfill Settlement

This report will provide information regarding landfill gas generation and groundwater quality. However,

due to current construction activities for the redevelopment of the landfill, no information with regards to

settlement is provided within this document. Landfill settlement will be addressed upon completion of

construction.

The FDEP reviews stabilization of a landfill based on certain criteria. These criteria include metrics for

settlement stabilization, landfill gas, and water quality as follows:

FDEP Solid Waste Management Rules 17-7 and 62-701 provide the same definition for landfill stabilization:

“biological and chemical decomposition of the wastes has ceased or diminished to a level so that

such decomposition no longer poses a pollution, health, or safety hazard.”

FDEP Rule 17-7.073(4) states:

“methane concentrations shall not exceed the LEL (lower explosive limit) at the property boundary

or 25% of the LEL within structures on the property.”

The current FDEP Rule (62-701.530) notes the following:

“landfill gas shall not exceed 25% of the lower LEL for combustible gases in structures on- or off-

site, excluding control or recovery components, and shall not exceed the LEL for combustible gases

at or beyond the landfill boundary.”

In January 2015, the previous owner, Landhill, Inc. submitted the last SAR that documented landfill gas and

groundwater monitoring. Results of that report indicated that landfill gases were still be generated in the

vent wells located on the landfill, and groundwater quality exceeded regulatory limits in select wells along

the landfill perimeter.

2.0 Landfill Gas Generation Kimley-Horn reviewed previous SARs prepared by the previous owner that indicated that landfill gases

were not recorded along the landfill perimeter, but were detected in the landfill footprint. Studies conducted

in 1989, 2008, and 2011 collected landfill gas measurements through a series of landfill gas probes installed

at the landfill perimeter. Data from those investigations did not identify landfill gases exceeding the LEL at

the property boundary. However, data collected from the three landfill gas vent wells located within the

landfill footprint did identify landfill gases at concentrations at ranges from 170 percent of the LEL to 458

percent of the LEL.

2.1 LANDFILL GAS INVESTIGATION – OCTOBER 2015

Kimley-Horn collected landfill gas measurements in accordance with the landfill permit from the vent

wells located on the landfill footprint (Figure 2). It should be noted that the vent well located in the

southeastern portion of the landfill was destroyed during site redevelopment activities, and could not

be sampled.

The landfill gas measurements were collected in a four part sequence. Initial readings were collected

from ambient air, away from the vent wells. The next readings were collected just outside the vent

well opening and inside the vent wells, approximately two feet into the vent well. After the readings

were collected, a heavy duty plastic bag was placed over the vent well opening and sealed with duct

tape. The wells were closed for a period of approximately 96 hours. At that time, landfill gas

measurements were collected by penetrating the plastic bag with the landfill gas meter tubing. Data

collected during this investigation is provided in Table 1.

3.0 Groundwater Monitoring

Based on conversations with FDEP in August 2015, it was determined that groundwater monitoring

associated with the facility will coincide with the established semi-annual monitoring schedule. However, it

was also understood that the monitoring may vary based on construction schedule and the FDEP would be

flexible with regards to schedule provided the responsible party was meeting the intent of the permit. FDEP

also indicated that the standard list of parameters stated in the long term care permit (Specific Condition

16b) be analyzed instead of the reduced list (Specific Condition 16c) for the first sampling event.

Groundwater field sampling activities were conducted October 28-29, 2014, in accordance with FDEP

Standard Operating Procedures (SOPs). All sampling equipment and down-hole tools were

decontaminated prior to and between sample locations. Copies of the groundwater sampling logs are

included in Appendix A. All laboratory analyses were performed by an accredited member of NELAC

(National Environmental Laboratories Accreditation Conference). The following summarizes the scope and

methodology associated with the groundwater sampling activities.

3.1 GROUNDWATER FLOW DIRECTION

Prior to sampling activities, each well was opened to allow for equilibration with the atmosphere.

Depth to groundwater measurements were collected to evaluate groundwater flow direction. The

water table elevation was determined by subtracting the depth to groundwater measurements from

the top-of-casing elevation data. Generally, groundwater flow was determined to be from the south

to the north, toward the stormwater pond. Top-of-casing and water table elevation data are included

in Table 2. A groundwater flow map is depicted on Figure 3.

3.2 GROUNDWATER SAMPLING

Samples were collected from groundwater monitoring wells listed in Specific Condition 15 of the

permit. In addition, monitoring well TW-4, installed during the Phase II conducted by Kimley-Horn

in October 2014, was sampled. Each groundwater monitoring well was purged prior to sampling

according to FDEP SOPs. Throughout the purging process, field parameters, including

temperature, pH, specific conductivity, dissolved oxygen (DO), and turbidity were measured and

recorded on Groundwater Sampling Logs (Form FD 9000-24; Appendix A). Field parameters are

summarized on Table 3. The monitoring wells were purged until field parameters met the FDEP

stabilization criteria for groundwater sampling. The groundwater samples were collected in

laboratory supplied containers and shipped under chain of custody documentation. All of the

groundwater samples were analyzed for the following parameters:

4.0 Sampling Results

4.1 LANDFILL GAS DATA

The following is a summary of landfill gas data collected from the two viable vent wells (North Vent Well [N-

VW] and Southwest Vent Well [SW-VW]) located on the landfill footprint. Landfill gas data are provided on

Table 1.

4.1.1 Hydrogen Sulfide (H2S)

During the ambient sampling and the areas outside and inside the vent wells, there were no H2S

recorded. However, after the vent well was closed off and landfill gases were allowed to

accumulate, hydrogen sulfide concentrations rose from non-detect to greater than 100 parts per

million (ppm) in the N-VW and up to 4 ppm in the SW-VW.

4.1.2 Methane (CH4)

During the ambient sampling and the area outside the vent wells, there were no methane gas

concentrations recorded. However, concentrations were recorded at the N-VW above the lower

explosive limit (LEL) (10% by volume) and at 18 percent of the LEL in the SW-VW.

Readings taken after the wells had been closed off showed a significant increase, with methane

concentrations of 45% by volume in the SW-VW and 56% by volume in the N-VW.

4.1.3 Carbon Monoxide (CO)

Carbon monoxide readings collected from the ambient air and outside the vent wells did not

exceed the instruments detection limits. Carbon monoxide was not detected inside or when the

well was closed at the SW-VW. Concentrations of CO were detected inside N-VW at 2ppm and

at 3ppm when the well was closed.

4.1.4 Oxygen (O2)

Oxygen content remained static for both the ambient and outside the well vents for both wells.

There was a slight decrease in O2 measured inside the well, but a significant decrease in O2

content when landfill gases were allowed to accumulate during the well closure.

4.2 GROUNDWATER QUALITY DATA

The following is a summary of groundwater quality data collected from the Site. Groundwater

analytical data are provided on Table 4. A copy of the laboratory analytical report is included in

Attachment B. For the purposes of this investigation, MW-11, located in the southwest corner of

the landfill, is considered the upgradient, background well.

4.2.1 Benzene

Benzene was not detected above the laboratory method detection limit (MDL) in any of the

samples collected.

4.2.2 Bicarbonate

Bicarbonate was detected in background well MW-11 at a concentration of 380 mg/L. The

remaining wells contained bicarbonate concentrations ranging from 660 mg/L (MW-3) to 2,000

mg/L (TW-4), all above background concentrations.

4.2.3 Chloride

Chloride concentrations ranged from 9.4 mg/L in well background MW-11 to 400 mg/L in the

sample from MW-7A. With the exception of the results from well MW-7A, all wells sampled at

the site have chloride concentrations below the applicable Groundwater Cleanup Target Level

(GCTL) of 250 mg/L.

4.2.4 Nitrate

Nitrate was detected in MW-5A, MW-7A, MW-8A, and MW-9 at concentrations below the

applicable GCTL of 10 mg/L. All other wells were below the laboratory MDL.

4.2.5 Ammonia

Ammonia was detected above the Natural Attenuation Default Concentration (NADC) of 28 mg/L

at TW-4, MW-7A, MW-8A, and MW-9. Ammonia was also detected above the GCTL at MW-12

and MW-13. Ammonia was detected at MW-3 and MW-11 at concentrations below the GCTL.

4.2.6 Total Dissolved Solids (TDS)

TDS concentrations ranged from 520 mg/L in background well MW-11 to 2,600 mg/L in well

MW-7A. TDS concentrations exceeded the GCTL of 500 mg/L for all wells.

4.2.7 Total Organic Carbon (TOC)

Total organic carbon (TOC) was detected in background well MW-11 at a concentration of 4.6

mg/L. All other wells ranged from 17 mg/L to 74 mg/L.


8

4.2.8 Metals

Arsenic was detected in MW-3 at a concentration of 32.6 ug/L, exceeding the GCTL of 10 ug/L.

No other groundwater samples contained arsenic above the method detection limits.

Iron was detected in all sampling locations, ranging from 161 ug/L to 16,100 ug/L.

Concentrations detected at MW-5A (16,100 ug/L), MW-7A (7,440 ug/L), MW-8A (9,440 ug/L),

and MW-9 (3,880 ug/L) exceed the NADC (3,000 ug/L). Concentrations detected at MW-3

(2,270 ug/L), MW-11 (328 ug/L), and MW-13 (1,730 ug/L) exceed the GCTL (300 ug/L).

Concentrations of sodium were detected above the GCTL (160 mg/L) at MW-5A (223 mg/L) and

MW-7A (356 mg/L).

All other metals parameters were either below their respective GCTL or below the laboratory’s

MDLs.

5.0 Discussion and Conclusions The following provides a discussion of the results obtained during this limited investigation for the Site.

LANDFILL GASES

There was an increase in landfill gas concentrations when measurements were collected from inside

vent wells at normal conditions relative to measures collected from the sealed vent wells. Methane

concentrations increased significantly in both wells, while oxygen content decreased when the wells

were closed off. These results suggest that the landfill is still generating landfill gases at

concentrations exceeding the LEL. Based on these measurements, a landfill gas mitigation plan is

being prepared to address gas migration into structures once construction is complete. This plan

will also address potential offsite migration of landfill gases post-construction, during long term care

of the landfill.

GROUNDWATER CONCENTRATIONS

Concentrations of ammonia, bicarbonate, chloride, iron, TDS, TOC, and sodium were identified in

all samples collected from the perimeter of the Site. Other parameters were also detected, but at

levels below the applicable GCTLs, or were not detected above the laboratory MDLs.

Ammonia concentrations in TW-4, MW-7A, MW-8A, and MW-9 all exceeded the NADC, while

concentrations in MW-5A, MW-12, and MW-13 exceeded the GCTL. The levels of ammonia

concentrations appear to be concentrated in the northeastern portion of the site. This distribution

may suggest that groundwater flow within the landfill is from southwest to northeast, similar to

regional groundwater flow. It also suggests that degradation of landfill material is ongoing.

Bicarbonate concentrations in down-gradient wells were greater than the background concentration

identified in MW-11, which may indicate that degradation of organic material is ongoing.

Chloride was detected in MW-7A (400 mg/L) at a concentration exceeding the GCTL of 250 mg/L.

This may be attributed to offsite contributions from the adjacent stormwater conveyance stream to

the north or other sources

Iron concentrations in MW-5A, MW-7A, MW-8A, and MW-9 exceeded the NADC, while

concentrations in MW-3, MW-11, and MW-13 exceeded the GCTL. This is consistent with historical

observations.

TDS concentrations exceeded the GCTL in all wells, and is typical of historical observations.


10

TOC was identified in background well MW-11 at a concentration of 4.6 mg/L. TOC was identified

in all other wells ranging from 17 mg/L to 74 mg/L, which may suggest that degradation of organic

material is ongoing.

Sodium was also detected in all samples collected. However, samples from wells MW-5A and MW-

7A, in the northwestern and northern portions of the Site, were the only samples found to exceed

the GCTL. Historical sodium concentrations were reported for MW-5A, located at the northwest

corner of the site, during the years 1996-2008. During these years, sodium concentrations averaged

199 mg/L, exceeding the sodium GCTL of 160 mg/L. The sodium concentration identified during

this investigation at MW-5A (223 mg/L) is similar to that period. MW-13 was installed closer to the

landfill in August 2008 in order to compare sodium levels between wells MW-5A and MW-13.

Sodium concentrations since 2008 have generally been lower for MW-13 compared to MW-5A. In

an April 2014 sampling event conducted by the previous owner, sodium concentrations were

identified in MW-5A at 235 mg/L and MW-13 at 59.9 mg/L. The samples collected during this

investigation seem to mirror this same relationship of higher sodium concentrations closer to the

property boundary than the landfill, indicating an offsite source. It should be noted that the adjacent

Toytown Landfill contains a sodium bentonite slurry wall that recently may have been disturbed

during the installation of a new underdrain system that may be contributing to elevated sodium

concentrations along the property border, in the area of MW-5A and MW-7A.

Kimley-Horn also reviewed several documents pertaining to previous environmental investigations

completed to address arsenic. Historical arsenic concentrations were reported for MW-3 during the

years 1996-2007. This monitoring well is located along the western property boundary of the

property. Arsenic concentrations during these years averaged 42 ug/L, which exceeded the GCTL

for arsenic of 10 ug/L. The arsenic concentration identified during this investigation at MW-3 (32.6

ug/L) is similar to that period. Investigative well MW-12 was installed in 2007 to compare subsequent

sampling results to those collected from MW-3. MW-12 is located approximately 100 feet eastward

of MW-3, closer to the solid waste disposal area. Since August 2007, arsenic concentrations at

MW-12 have been below the laboratory MDL or below the GCTL, while arsenic concentrations at

MW-3 have continued to exceed the GCTL. During this investigation, the arsenic concentrations

observed at these locations indicate higher arsenic levels at MW-3, furthest away from the disposal

area and nearest the property border, suggesting an offsite arsenic source.

The identification of metals, TDS, and ammonia in groundwater is common in association with

closed landfills. As previously suggested by the former landfill owner’s consultant, “The identification

of metals in groundwater may be due to what is termed the “shadowing effect” as described in the

January 31, 2006 FDEP memorandum titled “Secondary Ground Water Standards at Solid Waste


11

facilities, SWM-13.9” from Richard Tedder, Program Administrator, of the Solid Waste Section at

that time. The shadowing effect occurs when metals within aquifer matrix material are mobilized

due to a change in the valence state of the groundwater resulting from the construction of an

impervious surface, such as a landfill liner/cap, over the affected aquifer.”

Construction activities call for the opening and redistribution of landfill waste. During this time, it is

anticipated that landfill gas concentrations will dissipate, thus changing the nature of leachate

generation. It is also anticipated that the settlement of the landfill will be addressed. Based on the

ongoing construction activities at the landfill, Kimley-Horn recommends continued semi-annual

monitoring until construction activities are completed, at which time the Long Term Care program

for the landfill will be re-evaluated and potentially modified in the permit.

PQL: Practical Quantitation Limit.PQL

B Results are based upon membrane filter colony counts that are outside the method indicated ideal range.

I The reported value is between the laboratory method detection limit (MDL) and the practical quantitation

limit (PQL).

J Estimated value.

K Off-scale low; Actual value is known to be less than the value given.

L Off-scale high; Actual value is known to be greater than value given.

M Presence of analyte is verified but not quantified; the actual value is less than the MRL but greater than the

MDL.

N Presumptive evidence of presence of material.

O Sampled, but analysis lost or not performed.

Q Sample exceeded the accepted holding time.

T Value reported is less than the laboratory method detection limit. The value is reported for informational

purposes only and shall not be used in statistical analysis.

U Indicates that the compound was analyzed for but not detected.

V Indicates that the analyte was detected in both the sample and the associated method blank.

Y The laboratory analysis was from an improperly preserved sample. The data may not be accurate.

Z Too many colonies were present (TNTC); the numeric value represents the filtration volume.

? Data are rejected and should not be used. Some or all of the quality control data for the analyte were

outside criteria, and the presence or absence of the analyte cannot be determined from the data.

* Not reported due to interference.

The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was

accepted based on acceptable LCS recovery.
