>< <br />.~ <br />[~ ® Mr. Joe Dudash <br />~~ February 27, 1997 <br />Page 2 <br />results are given. In the response to the Division's adequacy gssestion no. 8 for the 1994 Annual <br />Report, TerraMatrix stated that these parmneters would be inclssded in post-1996 water quality <br />analyses. Please explain why these parameters could not be tested in 1995. <br />onset The above mentioned parameters were not tested in 1995 due to the fact that <br />the CDMG review of the 1994 Annual Reclamation Report was received by TerraMatrix <br />on November 30, 1995. The field tests for dissolved oxygen and turbidity were <br />incorporated into the 1996 field monitoring regimen with the following results: <br />Date Site Dissolved Oxygen Turbidity Femarks <br /> Img/I) <br />4/16/96 LHG 8.46 N/A No field turbidity due to <br /> problems with <br />4/16!96 UHG 8.71 N/A instrument <br />5/13/96 LHG 5.94 N/A No field turbidity due to <br /> problems with <br />5/13/96 UHG 6.21 N/A instrument <br />5/13/96 HG-6 7.38 N/A <br />FALL 1996 All sites N/A N/A No field D.O. or <br /> turbidity due to <br /> problems with <br /> instruments <br />The instrument problems have been resolved and the field measurement of dissolved <br />oxygen and turbidity will be performed for all future monitoring events. <br />5) In Exhibit 5 of the 1995 Annual Report, for the groundwater monitoring field data resss/ts, the <br />depth to water for well HG2 changed irons an average of about 90 feet in 1994 to an average of <br />about 49.5 feet in 1995. Please provide a discussion of what TerraMatrix believes is the reason <br />for such a dramatic change. <br />ResQonse: Please find attached, in Exhibit B, two (2) graphs illustrating the depth to water <br />in wells HG1 and HG2 from November 1987 to November 1996. It should be noted that <br />average annual depth to water is not the most appropriate measure of change because it <br />doesn't reflect seasonal variation. As can be seen from the graphs, water levels in well HG2 <br />have historically shown much greater fluctuation than HG1 and a 40+ foot seasonal <br />increase from fall to spring has been previously observed. We believe that the cltange <br />observed between 1994 and 1995 is consistent with this trend and is a resuh of an unusually <br />dry year during 1994 and an especially wet winter and spring of 1994/1995. The total <br />precipitation measured at the Hayden Weather Station during 1994 was 12.21", well below <br />the 30-year average of 16.94" annually. In April, May and June 1995 alone there was 8.5" <br />of precipitation. This heavy precipitation following a previously dry year would produce <br />a substantial recharge to the groundwater system in the area and would account fora 40+ <br />foot increase in the water level in well HG2. The pertinent data from the National <br />Weather Service in Hayden, Colorado is attached in Exhibit C. <br />H \R]9\1915RF5P LTR <br />1/t//9J rpl <br />
