Afrer <br />• rinsing, the bailer was gently lowered into the water column in the well. The sample was <br />obtained, striving to disturb the well water column as little as possible during sampling and <br />retrieval. Prior to measurement, instruments and equipment were rinsed with distilled water. <br />Field pazameters were measured and the water sample was divided into the proper sample <br />bottles, sealed, cooled as appropriate, boxed, and delivered to the laboratory for analysis. In <br />some cases, samples may not be available since there was insufficient water for sampling. This <br />means that there was not enough water to fill the sample bottles, plus provide an additional 300 <br />to 500 ml of sample for rinsing and field parameter measurement. <br />LJ <br />• <br />31-0j1.a50 Pagel rig r( a(er ngineers <br />
