PQL-method detection limit(from the most recent laboratory data). <br /> 3.N-no primary maximum contaminant level <br /> 4 Bicarbonate alkalinity quantified as CaCO3,total alkalinity calculated as sum of Bicarbonate and Carbonate alkalinity <br /> quantified as CaCO3. <br /> Monitoring Points <br /> The monitoring points for groundwater are LP-1 through LP-7 and PW-1-48, as shown on <br /> Figure 1. The monitoring point for each the wastewater in each surface impoundment is at the <br /> point of discharge to each impoundment. <br />
