<br />TABLE 4 -8
<br />SAMPLE LOCATION: WCMW -3
<br />DRAINAGE: WILSON CREEK
<br />PERIOD OF RECORD: 1992 -2011
<br />ND = Not determined Applicable in two cases: number of analyses = 1 or all analyses are non - detect.
<br />Non - detect analyses are set at 1/2 the detection limit for average and tandard deviation calculations.
<br />Median calculations use the laboratory analyses with less than detection values as negative.
<br />Dissolved arsenic was analyzed from 1992 -1995 and since 2002 Total recoverable arsenic was analyzed from 1995 -2002. Both forms are provided to indicate the entire analytical history.
