Notes: A value of NT indicates that this sample was not tested for a particular contaminant. A value of ND indicates that the contaminant was not detected in the test that was done for it. *Indicates that the MCL (Maximum Contaminant Level) for drinking water is a secondary standard by the EPA. ^ Indicates a Chemical Contaminant Candidate issued by the EPA. # Indicates concentrations in excess of 0.1 mg/L suggest domestic of agricultural sources of waste.
