Boulder Creek Water Quality Index
|6-parameter Test||result||unit||Q-value||weight factor||total|
|Fecal Coliform||<10||#/100 mL||80||0.16||12.8|
|Total Phosphate||0.22||mg/L PO4-P||80||0.10||8|
|totals (factors, total)||0.72||47.18|
The WQI is computed by converting measured Water Quality Parameters to "Q-Values" using charts developed by the National Sanitation Foundation (NSF) water quality scientists. The Q-Values are then multiplied by a weighting factor based on the importance of that water quality parameter.
