June 1998 4 <br /> Energy Fuels Coal, Inc. 1997 Aoaual Hy&-o]W Report <br /> QUARTERLY HYDROLOGY MONITORING PROGRAM <br /> DATA SUMMARY <br /> (Period July 1, 1996 through December 31, 1997) <br /> Introduction <br /> This section of the 1997 AHR presents all surface and ground water data collected at the <br /> Southfield Mine from 1979 through the end of the reporting period. Discussion of these data, <br /> including potential impacts and trends, follows below. <br /> Surface Water <br /> Field and laboratory data collected from approved monitoring points on Newlin, Oak, Magpie <br /> and Second Alkali Creeks are shown on water quality Tables 10, 11, 12, 13, 14, 15, 16, and <br /> 17. Stream flow measurements for these monitoring locations are summarized on Table 9. <br /> Monitoring of upstream and downstream locations on Newlin, Magpie and Oak Creeks was <br /> suggested in the Division's Mid-Term review of the Southfield permit. EFCI agreed that this <br /> approach would provide more useful data than the currently approved single monitoring point <br /> on each of these creeks. This change of monitoring plan is included with Technical Revision <br /> No. 29, currently under review. EFCI voluntarily began monitoring two locations on the <br /> referenced creeks during the second quarter of 1997. Data from the additional monitoring is <br /> included in the stream quality and quantity data summary tables. <br /> Stream flows occurred during the spring and summer months in response to snowmelt and <br /> precipitation events during the reporting period. Measurable flows were monitored in all the <br /> streams. Newlin Creek flowed, at low levels, through June 1996 due to heavy rains received <br /> during early Spring. In Oak Creek, low flows persisted during the second and third quarters <br /> of the reporting period. Similar to previous reporting periods, Second Alkali Creek exhibited <br /> infrequent, low flow patterns in response to precipitation events. <br /> Water quality data, shown on the attached tables, indicate no unusual or harmful trends. Data <br /> for Oak Creek indicate slightly increasing levels of TDS, calcium, and sulfate as compared to <br /> previous monitoring periods. Field measurements of conductivity similarly show an upward <br /> trend. Heavy metal concentrations are at or below levels of previous monitoring data. <br /> The data for Newlin Creek, obtained only during the 2nd quarter of 1997, are comparable to <br /> ranges found in previous monitoring periods. No deterioration of Newlin Creek or Oak Creek <br /> is apparent from the water quality data collected to date. <br /> Monitoring data from Magpie Creek show increasing levels of calcium, aluminum, sulfate, <br /> iron, and manganese. These data were obtained at the upstream sampling site and are not <br />
