• 6. Ground Water Protection <br />Proposed and current CKD Disposal sites - As noted in the letter of December 23, 1998, <br />three wells had been established to monitor water quality. One well (MW-1) was up- <br />gradient of the proposed and active CKD dump and the other two (MW-2 and MW-3) <br />are down-gradient. Locations of the wells are shown on Exhibit C and a complete <br />assessment of the holes are included in the Hydrogeologic and Geochemical Assessment <br />of Holnam, Inc.'s Proposed CKD Disposal Si[e report completed by SECOR <br />International and submitted to the MLRB in January of 1999. <br />[n accordance with Rule 3.1.7 of the Construction Materials Rules, SECOR International <br />Inc. has been contracted to monitor the wells and collect eight samples over the n~:xt five <br />quarters. The first sampling round was completed on April 28, 1999. Complete ~malysis <br />of the water based on Human Health Standards, Secondary Drinking Water Standards, <br />Agricultural Standards, and TDS Water Quality Standazds aze being completed. Results <br />from the first round of sampling were forwarded to the MLRB in July of 1999. <br />As required in the MLRB letter of December 28, 1998, a fourth well was drilled clown- <br />gradient ofthe existing CKD monofill. Location of the fourth well (MW-4) is shown on <br />Exhibit C. The fourth well will be included in the monitoring process with the other <br />three wells and a complete analysis based on Human Health Standazds, Secondary <br />Drinking Water Standards, Agricultural Standazds, and TDS Water Quality Standards <br />• will be completed so as to compare the data between wells. <br />Future monitoring of the wells is being planned on; however, the frequency of sampling <br />is pending the five-quarter results of the wells. <br /> <br />
