Notes:
U-indicates that the analyte was analyzed for but not detected. Detection
limit is numeric value shown. a) MCL source: Table 1 Human Health Standards, Regulation 41.
Q-indicates elevated reporting limit due to high analyte level. b)MCL source: Table 2 Secondary Drinking Water Standards, Regulation 41.
All units are in mg/L unless noted otherwise. c) MCL source: Table 3 Agricultural Standards for Groundwater, Regulation 41.
NA indicates not available. d) MCL for nitrate is 10.0 mg/L as N
Bolded values=MCL exceeded, italicized values=reporting limit greater than MCL. e) MCL for nitrite is 1.0 mg/L as N
B-Estimated result. Result is less than the reporting limit. J-Method blank contamination. The associated method blank contains the target analyte at a reportable level.
