45	Measures	Units
46	Total e-coli	CFU/100ml			Quebec requires that E Coli should be less than 10 CFU per 100ml for drinking water - below 100 CFU for swimming (mean of at least 5 samples)											RSVL guide		Reporting detection limit seems to vary between 4 and 10 CFU/100 ml
47	Total Kjeldahl Nitrogen	mg/l			Target levels for nitrogen (total kjedahl nitrogen TKNTP in drinking water are 0.02 mg/L. The reporting detection limit (RDL) is 0.05													The reporting detection limit (RDL) is 0.05
48	Total Phosphorus	mg/l			Target levels for Phosphorus in an uncontaminated lake are below .005 mg/L													RDL .005
49	Water clarity				Secchi measurement of water clarity target is above 5 meters for Oligotrophe (above 4 for Oligo-mesotrophe)
