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