The ground water surface elevation (in feet and hundredths, MSL) in all wells shall be measured on a quarterly basis and used to determine the direction of ground water flow. This information shall be displayed on a water table contour map and/or ground water flow net for the site. Samples from all wells shall be analyzed for the following parameters and constituents: Sampling Report in & Reporting Parameter/Constituent Units of Frequency ,Specific Conductance (field) umhos/cm Quarterly pH (field) Number Quarterly (Dissolved) or (Total) Organic Carbon mg/l Quarterly Total Dissolved Solids (TDS) mg/l Quarterly Chloride mg/l Quarterly Sulfate mg/l Quarterly Dissolved Iron mg/l Quarterly Carbonate mg/l Quarterly Bicarbonate mg/l Quarterly Alkalinity mg/l Quarterly Nitrate (as N) mg/l Quarterly Sulfides (including H2S) presence or 2 absence Quarterly Volatile 1 Organics ug/l Annually Aluminum mg/l Annually Antimony mg/l Annually Arsenic 1 mg/l Annually Cadmium mg/l Annually Total Chromium (III+VI)1 mg/l Annually Chromip (VI) mg/l Annually Capper mg/l Annually Lead 1 mg/l Annually Manganese mg/l Annually Mercury mg/l Annually Nickel mg/l Annually Selenium mg/l Annually Silveri mg/l Annually Thallium mg/l Annually Zinci mg/l Annually t Inductively Coupled Argon Plasma Atomic Emission Spectroscopy (ICAP) may be usefor analysis of these constituents only.
