<br />PERIOD OF RECORD: 1993 -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 standard deviation calculations.
<br />Median calculations use the laboratory analyses with less than detection values as negative
<br />Dissolved arsenic was analyzed from 1993 -1995 and since 2001. Total recoverable arsenic was analyzed from 1993 -2002. Both forms are provided to indicate the entire analytical history.
