I. OVERVIEW OF THE MCGRATH LAKE SURVEY

Actual field and laboratory work is performed under contract by the San Jose State UniversityFoundation-Moss Landing Marine Laboratories. Toxicity testing is performed at the CaliforniaDepartment ofFish and Game (CDFG), Marine Pollution Studies Laboratory at Granite Canyon, south ofCarmel. Collection activities are distributed by Russell Fairey of San Jose State University at the MossLanding Marine Laboratories (MLML) in Moss Landing. Dr. John Oliver is subcontracted to performthe TOC and grain size analyses, as well as to perform the benthic community analyses. MLML alsocontracted Applied Marine Sciences in League City, Texas to perform TOC and grain size analyses. BCLaboratories in Bakersfield, California, are contracted to perform nutrient analyses. CDFG personnelperform the trace metals analyses at the trace metals facility at Moss Landing Marine Laboratories inMoss Landing. The synthetic organic pesticides, PAHs and PCBs are contracted by MLML to BattelleLaboratories in Duxbury, Massachusetts. MLML currently maintains the database for the RWQCB.Described below is a description of that database system.

Sediment Chemistry Summations and Quotients

CHEMICAL SUMMATIONS AND QUOTIENTS

In the following section, chemical summations (total chlordane, total DDT, total PCBs, LMWPAHs, HMW PAHs, total PAHs) and quotients (ERM and PEL) are presented. For purposes ofthese summations, samples which were found to have chemical concentrations less than themethod detection limit (-8 in Appendix C) were adjusted to a value of one-half of the methoddetection limits given in the methods description. The summations were calculated as follows:

Total chlordane(TTL_CHLR) = L ([cis-Chlordane] [trans-Chlordane] [cis-Nonachlor][trans-Nonachlor] [Oxychlordane])

Total DDT(TTL_DDT) = L ([o',p'DDD] [p',p'DDD] [O',pl DDE] [p',p'DDE] [O',pl DDT][p',p' DDT])

Total PCB(TTL_PCB) = L ([PCB8] [PCBI8] [PCB28] [PCB44] [PCB52] [PCB66][PCBI0l] [PCBI05] [PCB 11 8] [PCBI28] [PCBI38] [PCB153] [PCB170][PCB 180] [PCB 187] [PCB 195] [PCB206] [PCB209])

Low Molecular Weight PAHs(LMW_PAH) = L ([ACE] [ACY] [ANT] [BPH] [DMN] [FLU][MNPl] [MNP2] [MPHl] [NPH] [PHN] [TMN])

High Molecular Weight PAHs(HMW_PAH) = L ([BAA] [BAP] [BBF] [BKF] [BGP] [BEP][CRR] [DBA] [FLA] [IND] [PER] [PYR])

Total PAHs(TTL_PAH) = L ([LMWYAH] [BMW_PAH])

ERM Quotients and PEL Quotients were calculated using summations of the individual chemicalsfor which ERMs and PELs have been derived. Chemical concentrations are divided by theirrespective ERM or PEL values to obtain a specific individual chemical quotient (Example 1).TTLDDTQE (P) is expressed as: (TTL_DDT/TOC)/lOO, where TTL_DDT is the sum of the sixDDT metabolites, TOC is the total organic carbon content of the sample, and 100 reflects the 100J.lg/g DDT/TOC value reported by Swarzt to be associated with biological effect. A value greaterthan one indicates the chemical concentration in that sample exceeded its respective guidelinevalue. A value of five would indicate the chemical was five times higher than the respectiveguideline value in that sample.

Example 1 - sample IDORG #199 Copper concentration = 170 mg/gPEL for copper = 108.2

CopperQ = (170 J.lg/g) / (108.2 J.lg/g) = 1.57

Summations and averaging of the individual chemical quotients were calculated to give summaryERM Quotients (ERMQ) and PEL Quotients (PELQ). Each quotient summation is divided by thenumber of analytes used in the summation to yield an average summary quotient.

Summary ERM Quotient

ERMQ = ((ANTIMONYQ + ARSENICQ + CADMIUMQ + CHROMIUMQ +COPPERQ + LEADQ + MERCURYQ + SILVERQ + ZINCQ + TTL DDTQ +TTL Cffi.,RQ + DIELDRINQ + ENDRINQ + TTL PCBQ + LMW PAHQ +- --HMW-,PAHQ) / 16)

Summary PEL Quotient

PELQ = ((ARSENICQ + CADMIUMQ + CHROMIUMQ + COPPERQ + LEADQ +MERCURYQ + SILVERQ + ZINCQ + TTL_DDTQ + TTL_Cffi.,RQ + DIELDRINQ +LINDANEQ + TTL_PCBQ + LMWY AHQ + HMWY AHQ) / 15)
