Freshwater Water Sampling Results: Fecal
Coliform
For graphs of this data, go here.
For map of sample sites, go here.
Water Quality Test: Membrane filtration (mTEC medium
+ urea method)
W = Webhannet River, P = Pope's Creek, D = Depot Brook,
B = Blacksmith Brook,
TNTC = too numerous to count, n.d. = no data
Higher number sites are further upstream.
Decimal figures are sometimes presented because two dilutions
were run and averaged, or a plate was counted twice for quality control
and the results were averaged.
Fecal coliform results reported as CFU/100mL (colony forming units per 100mL of sample water)
