IV. GROUND-WATER SAMPLING AND ANALYSIS PLAN <br /> The sampling and analysis procedures for the proposed ground-water <br /> monitoring system are described below. The procedures are provided so <br /> that consistent and reproducible methods are used to obtain samples <br /> from monitoring wells and that proper analyses are performed on the <br /> samples. <br /> A. MONITORING PARAMETERS <br /> To establish baseline ground-water quality data for the site, EMCON <br /> analyzed ground-water samples from Wells G-1 and G-2 for the following <br /> parameters: <br /> • Volatile organic compounds, • Total organic <br /> according to EPA Method 624 carbon <br /> • Semivolatile organic • Chloride <br /> compounds, according to EPA <br /> Method 625 • Nitrate <br /> • Pesticides and polychlorinated • Iron <br /> biphenyls, according to EPA <br /> Method 608 • Total dissolved <br /> solids <br /> • Zinc <br /> • Electrical <br /> • Phenols conductivity <br /> • Alkalinity • Total Kjeldahl <br /> • 27 ICAP metals nitrogen <br /> 1 A discussion of the analytical results is contained in an EMCON <br /> Associates report (1987b) . Based on the results of the baseline moni- <br /> toring program and until such time as waste acceptance is initiated at <br /> the site, the following routine annual sampling and analytical program <br /> is recommended for Wells G-1, G-2, and G-3 (when installed) : <br /> • pH • Chloride <br /> • Electrical conductivity • Nitrate <br /> PJ9 9390207.00D 14 <br />
