- The detection limits were 3.29 ng/l and values below that limit are indicated as BDL

aOften referred to as interstitial water samples

bMercury was only detected in 20 (4 %) of the 479 total, pore and dissolved water samples collected between 2007 and 2009. Mercury was not detected in any of the pore-water samples and the BDL’s are shown to compare to the concentrations of mercury in the dissolved and total samples. Mercury was not detected at LF-1 but was detected at site LF-2 which is below the Colorado Springs, Colorado Las Vegas waste-water treatment plant. Sites LF-2 and LF-3 are in an agricultural setting, land usage primarily irrigated crops and grazing. LF-4 and LF-5 are within the City of Pueblo, Colorado

cDissolved samples of water were filtered through a 0.45 µM filter and total-water samples were unfiltered
