PICACHO SOLID WASTE SITE 

IMPERIAL COUNTY, CALIFORNIA 

The Picacho Solid Waste Site (PSWS) is located on federally-administered Quechan 

Tribal lands in the County of hnperial (County), California. Although California is a 

U.S. Environmental Protection Agency (EPA) approved state, because the facility is 

located on Tribal lands, which are held in trust by the federal government, the site is 

subject to the code of federal regulations (CFR) 40 CFR Part 258 ( 40 CFR 258), which 

regulates solid waste facilities. Any variations from the federal regulations must be 

approved by the EPA through the site-specific flexibility process. This process was 

developed by the EPA and described in a document entitled, Site Specific Flexibility 

Requests for Municipal Solid Waste Landfills in Indian Country- Draft Guidance (EPA, 

August 1997). Included in this guidance document are the requirements and instructions 

for preparing a site-specific flexibility request (SSFR) for modifying the list of 

groundwater monitoring parameters from those specified in 40 CFR 258.54(a). 

On behalf of Imperial County Department of Public Works (County), which operates the 

PSWS, GeoLogic Associates (GLA) has prepared this SSFR to modify the list of 

detection monitoring parameters provided in 40 CFR 258.54(a)(1) and (2). This SSFR 

was prepared based on information summarized in semiannual water quality monitoring 

reports prepared by GLA for the County, including the most recent first semiannual2007 

10 and annual report dated April2010, and the EPA (August, 1997) SSFR guidance 

document. 

1.0 BACKGROUND 

The PSWS groundwater monitoring network includes four wells (P-MW-1, 

P-MW-2, P-DW-3A, and P-MW-4) constructed in August 1994 (Figure 1). Initially, 

because California is an EPA-approved State regulating solid waste facilities within the 

State, the site was thought to fall under the jurisdiction of the California Regional Water 

Quality Control Board - Colorado River Basin Region, and site monitoring was 

performed in accordance with site-specific Waste Discharge Requirement No. 88-005, 

and the more recent blanket Waste Discharge Requirements No. 93-071, established for 

all active landfills within the Colorado River Basin Region and prepared to comply with 

federal regulations. Under this program, the wells have been monitored by the County 

typically on a semiannual basis beginning in November 1994. Monitoring included well 

P-DW-3A until March 1999 when this well, which is located in the site borrow area, was 

converted to a water level measuring station and sampling and analysis of groundwater 

from this well ceased. The monitoring program has included analysis of volatile organic 

compounds (VOCs) and inorganic constituents including chloride, nitrate as nitrogen, 

pH, sulfate and total dissolved solids, as well as field measured electrical conductivity. 
In contrast with 40 CFR 258, which requires sampling and analysis for its Appendix II 

list of constituents of concern (COCs) only if a release is identified, in accordance with 

California regulations, the current three-well monitoring network has been sampled every 

five years (in 1996, 2001, and 2006) for analysis of the Appendix I and Appendix II list 

of COCs. The current procedures provide historical water quality data for the full suite of 

COCs and are therefore more protective of water quality than the approach outlined in 40 

CFR 258. 

Accordingly, the semiannual detection monitoring program complies with EPA 

regulation 40 CFR 258.54(a) to include the constituents listed in Appendix I, with the 

exception of the 15 heavy metals, which are included in the sampling program every 5 

years. In accordance with 40 CFR 258.54(a)(2) and the SSFR guidance document, an 

alternate list of inorganic indicator parameters may be established in lieu of the 15 heavy 

metals included in Appendix I. The following section provides a discussion of the site 

groundwater chemistry and a request to include inorganic indicator parameters in lieu of 

the 15 heavy metals in Appendix I. A change in the anthropogenic constituent list 

(VOCs) is not proposed. 

2.0 SITE HYDROGEOLOGIC CONDITIONS 

Currently, more than 15 years of semiannual groundwater monitoring data have been 

obtained from the detection monitoring wells at the PSWS, with several sampling rounds 

that include analysis of samples for the full suite of 40 CFR 258 Appendix II COCs. 

Groundwater occurs at a depth of 180 to 200 feet below the ground surface, with 

variations in groundwater elevations of less than 0.5 foot across the entire site, resulting 

in a very low groundwater gradient ofless than 0.0004 ft/ft. Most recently, well P-MW-1 

or P-MW-4 have been the most upgradient well, though the differences between these 

wells vary by less than two tenths of a foot (Table 1). Historically groundwater flows to 

the east to southeast, altered primarily by an occasional heavy influx of flow in the 

adjacent wash and associated infiltration. 

General Chemistry. As presented in Tables 2 through 5, the general chemistry data 

indicate a relatively narrow range of values across the site (GLA, April2010). Median 

chloride concentrations range from about 110 to 140 mg/L; nitrate as nitrogen median 

values range from 1.9 to 2.5 mg/L; median pH values exhibit slightly basic conditions 

ranging from 7.9 to 8.1; median sulfate concentrations range from 86 mg/L to 109 mg/L 

and median total dissolved solids (TDS) concentrations range from about 540 to 622 

mg/L .. Only nitrate as nitrogen has a federal primary Maximum Contaminant Level 

(MCL) established for protection of drinking water quality, and the measured values at 

the PSWS are well below the MCL of 10 mg!L for this constituent. As a measure of the 

aesthetic water quality, federal secondary MCLs (SMCLs) are established as drinking 

water quality goals for public water systems for chloride, sulfate and TDS. Comparison 

of the median values measured in groundwater samples at the PSWS with the federal 

SMCLs indicates that only TDS concentrations slightly exceed the SMCL of 500 mg/L. 

M:\2001>-120\SSFR_GW MON PARAMETERS.DOC -2-
Heavy Metals. Based on the COC sampling rounds conducted at the PSWS, heavy metals 

are generally not detected in groundwater samples. Well P-MW-1 has been sampled six 

times for the 17 heavy metals listed in Appendices I and II. Of these, only arsenic and 

selenium have been measured three times in samples (Table 2). Other metals including 

barium, chromium, lead, mercury, tin, vanadium and zinc have been measured one or two 

times, but none above a federal MCL. Only arsenic values of0.012 to 0.014 mg/L 

slightly exceed the federal MCL of 0.010 mg/L. 

Well P-MW-2 has been sampled three times for the 17 COC metals, and only chromium 

was measured in samples from this well three times (Table 3). Barium, copper, thallium, 

vanadium and zinc were measured one or two times at quantifiable or estimated trace 

levels (between the laboratory method detection limit and practical quantitation limit), 

and no value exceeded a federal MCL. 

Well P-DW-3A has only been sampled one time for COCs (in 1996), and only chromium, 

tin and vanadium were detected during the sampling round though all three metal 

concentrations were low (Table 4). The measured chromium concentration was well 

below its federal MCL. 

Well P-MW-4, sampled three times for the COC metals, contained measurable chromium 

in all three sampling events (Table 5). The other detected heavy metals include barium, 

lead, tin, vanadium, and zinc, in one or two of the samples at quantifiable or estimated 

trace levels, and all were well below an established federal MCL. 

Volatile Organic Compounds. Several VOCs have been detected in samples at the 

PSWS, but only chloroform in samples from well P-MW -1 has been measured with any 

regularity. Concentrations of chloroform measured in samples from well P-MW-1 have 

ranged from 0.46 Jlg/L to 1.4 JlgiL, substantially below the federal MCL of 80 !Jg/L. 

Other detected VOCs include acetone, benzene, toluene, methylene chloride and 

chloromethane, which are common field or laboratory contaminants, and typically have 

been measured erratically in samples at estimated trace concentrations. A few VOCs 

such as dichlorodifluoromethane, trichlorofluoromethane, 4-methyl-2-pentanone 

(MIBK), 1,2,3-trichlorobenzene and naphthalene have been detected, also erratically, in 

samples and may be attributed to the landfill. 

Other anthropogenic compounds. Every five years groundwater samples have been 

analyzed for the COCs listed in 40 CFR 258 Appendix II including organochlorine 

pesticides, chlorinated herbicides, semi-volatile organic compounds and polychlorinated 

biphenyls. To date, results of these sample analyses have not identified any of these 

compounds in groundwater samples at the PSWS. The next 5-year COC sampling event 

is scheduled to be conducted during the Winter/Spring 2011 sampling event. 

3.0 ALTERNATIVE MONITORING PARAMETER LIST 

The current alternative list of monitoring parameters complies with 40 CFR 258 with the 

exception that the inorganic indicator parameters (chloride, nitrate as nitrogen, pH[field 

M:\20llfi.120\SSFR_GW MON PARAMETERS.DOC -3-
measured], electrical conductivity [field measured], sulfate, and TDS) are proposed in 

lieu of the 15 heavy metals included in 40 CFR 258 Appendix I, with the exception of 

arsenic, which may be present associated with pesticides. We request replacement of 

these 15 heavy metals with the inorganic indicator parameters currently included in the 

site's detection monitoring program on the following grounds: 

0 In our experience regarding the chemical composition of municipal solid waste 

leachate, and landfill impacted groundwater in southern California particularly, 

heavy metals are generally poor indicators of a release since many occur naturally, 

and exhibit significant spatial variability across a site. In fact, of the heavy metals 

included in 40 CFR 258 Appendices I and II, as presented in Section 2.0 above, only 

a few typically have been found in quantifiable concentrations that could be 

differentiated from background water quality. 

0 Heavy metals are not typically very mobile unless subjected to highly acidic 

conditions, and under normal conditions such as expected at the PSWS, would tend 

to adsorb to soil particles before reaching the groundwater more than 150 feet below 

the bottom of the waste, making them poor early indicators of a release relative to 

VOCs and more mobile inorganic metal surrogates. 

0 As stated, review of the metals data indicates few quantifiable values. In contrast, 

the inorganic indicator parameters are commonly identified and the abundant 

historical data allow for robust conclusions based on statistical and deterministic 

analysis of that data. The extremely low concentrations and sporadic frequency of 

detection of the heavy metals precludes thorough analysis and determination of a 

release. Similarly, the pH values for leachate are often more acidic than identified 

in groundwater samples at the PSWS. When there are statistically significant 

changes in the proposed indicator parameters, indications of a release may be 

recognized. 

Therefore, it is recommended that, with the exception of arsenic, the heavy metals be 

removed from the routine semiannual detection monitoring program. Arsenic was 

detected in groundwater samples from well P-MW-1 in 1994 and 1995 and may be 

associated with pesticides. Because this well is located in close proximity to the former 

pesticide container disposal pit, arsenic will be added to the list of monitoring 

parameters. The VOCs will continue to be included in the monitoring program, since they 

are anthropogenic and in the absence of other local sources are diagnostic of a landfill 

release to groundwater either by leachate or landfill gas migration. 

In summary, to provide the earliest possible indication of release from the landfill, it is 

requested that the proposed water quality monitoring program includes analysis of 

groundwater samples for the inorganic indicator parameters (chloride, nitrate as nitrogen, 

pH, electrical conductivity, sulfate and TDS) in lieu of the 40 CFR 258 Appendix I heavy 

metals, with the exception of arsenic, which will be added to the list of monitoring 

parameters. In addition, at a minimum, the detection monitoring program will continue 

to include the 40 CFR 258 Appendix I VOCs. The proposed list of monitoring 

M:\2006-120\SSFR_GW MON PARAMETERS.DOC -4-
parameters provides good indicators of changing water chemistry potentially associated 

with the release of leachate, pesticides, or landfill gas to groundwater at the site. 

It is also proposed that analysis continue to be conducted for the 40 CPR 258 Appendix II 

list of COCs every five years as required under California regulations as a further 

conservative approach to protection of water quality at the PSWS. 

4.0 CLOSURE

described herein. It may not contain sufficient information for other parties or purposes.

parameters, please give me a call.
