The sampling frequency for these new wells may <br /> be re-evaluated after two semi-annual sampling events. <br /> " New injection wells screened below the Corcoran clay will continuously monitor total volume, injection rate, and injection <br /> pressure. New injection wells screened above the Corcoran clay will continuously monitor total volume and injection rate, <br /> and injection pressure. <br /> pH, and temperature shall be measured whenever a sample is submitted for laboratory analysis <br /> EDB= Ethylene dibromide <br /> DBCP= 1,2-dibromo-3-chloropropane <br /> OC Pesticides=Organochlorine pesticides(Aldrin, Chlordane, DDD, DDE, DDT, Dieldrin, Heptachlor,Toaxaphene) <br /> OP Pesticides=Organophosphorus pesticides(DEF, Delnav, Dimethoate, Ethyl Parathion, Methly Parathion, Disyston) <br /> BHC Isomers=Benzene hexachloride(alpha, beta,delta, and gamma isomers) <br /> Herbicides=2,4-D(Dichlorophenoxyacetic acid)and 2,4,5-T(Trichlorophenoxyacetic acid) <br /> M= Monthly sampling frequency <br /> NR=Not required <br /> Q=Quarterly sampling frequency <br /> 5 =Semi-annual sampling frequency <br /> A=Annual sampling frequency <br /> = Not applicable <br />
