The bailer was fille,'and brought to the surface. Purge water was <br /> placed in a 55 gallon drum for storage onsite pending analytical results. At the <br /> beginning, during, and at the end of the purge process, measurements were taken for <br /> PH, electrical conductivity, and temperature of the purge water. This information was <br /> recorded on field water sampling data sheets and final values are presented in'fable A-2. <br /> TABLE A-2 <br /> FIELD WATER QUALITY NZASUREM EN TS <br /> END OF PURGE VALUES <br /> DECE1VIIiER 5, 1991 <br /> Well/Sarnpie pH Temperature(°F) Conductivity(umhos) <br /> MW-1 7.25 66.2 484 <br /> MW-2 NS NS NS <br /> MW-3 NS NS..._._.... ._ NS <br /> NS = Not Sampled due to dry well. <br /> To sample MW-I, the bailer was again lowered into the well, filled, and brought to the <br /> surface.
