<br />• <br />• <br />The lab samples are packed in a cooler and <br />transported to the lab the same day the samples are <br />taken. The parameters currently monitored during <br />laboratory analysis are listed as follows: <br />CAC03 to pH 4.5) <br />Specific conductance (mmhos/cm) <br />Lead - dissolved <br />Selenium - dissolved <br />Total dissolved solids (at 180°C) <br />Chloride <br />Sulfate (as S04) <br />SAR <br />Calcium - dissolved <br />Iron - dissolved <br />Magnesium - dissolved <br />Manganese- dissolved <br />Molybdenum - dissolved <br />Sodium - dissolved <br />Alkalinity - total (as <br />Carbonate (as CO3) <br />Hardness (as CACU3) <br />Bicarbonate (as H;03) <br />pH (pH units) <br />i~ <br />~X <br />Gam`! <br />~,/ U <br />i ~~• <br />The water laboratory reports from '92 are included <br />in this report. Each well was double sampled using <br />the two procedures discussed above for both the <br />third and fourth quarters of the year. When <br />analyzing the report, the parameter values denoted <br />by the "A" at the end of the well designation refer <br />to the five bailer volume purging procedure. The <br />parameter values denoted by the "B" at the end of <br />the well designation refer to the three casing <br />volume purging procedure. <br />There are differences in parameters between the two <br />procedures. At this point, it is impossible to <br />detect a pattern to relate data from both <br />procedures. Double sampling of the monitor wells <br />will continue until a reasonable relationship can be <br />determined. <br />Page 4 <br />
