<br />of the water quality data for the five wells are presented in Tables 42 thrax~i <br />51. <br />All of the wells are in the Fast Fnatcap Creek watershed. 'Ihe wells show a <br />general trerrl of increasing wnduetivity froan upstream to downstream. Water <br />quality in Well S1YI-7 located furthest upstream is calcium bicarbonate type with <br />~6 of about 175 mg/1. Sodium and sulfate oc~g~osition as well as 'IUS <br />wnoentrations increase progressively in wells located downstream. <br />Water levels from the five Roatcap Creek colluvial wells continue to show <br />seasonal variability with levels falling during late summer aryl rising during the <br />winter and spring. Seasonal fluctuations vary from 1 to 7 feet in all wells. <br />'Ihe seasonal levels fall during the late sun¢ner and rise during the winter and <br />spring. No anomalies or impacts on water levels were observed in 1992 at these <br />wells. <br />SURFACE WATER <br />Four ponds, two springs, and five surface water stations are monitored in the <br />Roatcap Creek watershed. Summaries and plots of the data are presented for the <br />five surface water stations, four ponds, and two springs. Water quality data <br />summaries for the oolluvial wells are presented as Tables 42 throuc~ 51. Flaw <br />data summaries for the surface water stations are presented as Tables 52 through <br />55, Water quality data summaries for the surface water stations are presented <br />as Tables 56 through 63. Water quality summaries for Roatcap Creek surface water <br />features presented in Tables 64 through 67, 104, 105, and 113. Tables in these <br />series which are blank e~ibited no flaws sufficient for sampling during 1992 <br />monitoring period. Plots of the flow rate and conductivity for colluvial wells, <br />surface water stations, and ponds are presented as Figures 21 throuc~ 29. <br />6 <br />
