28	Measures	Units
29	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
30	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
31	Total Phosphorus	mg/l			Target levels for Phosphorus in an uncontaminated lake are below .01 mg/L. RDL is .005													RDL .005
32	Water clarity				Secchi measurement of water clarity target is above 5 meters for Oligotrophe (above 4 for Oligo-mesotrophe)
33
34					Phosphorus	0.01 - 0.03 mg/L - the level in uncontaminated lakes					https://water-research.net/index.php/phosphates
35						0.025 - 0.1 mg/L - level at which plant growth (including algae) is stimulated
36						0.1 mg/L - maximum acceptable to avoid accelerated eutrophication
