Water Quality Compared to Reference						RP = reactive phosphorus
storm	condition	year =	(All)			TP = total phosphorus
						NN = nitrates + nitrites
						KN = kjeldahl nitrogen
(Values of 0.5 and 0.3 indicate large						TN = total nitrogen
and moderate differences respectively.)						SS = suspended solids
