One of the more recent questions asked regarding my IRL on Impacts of Golf Course's on the Surface Waters was... what are the EPA acceptable concentrations for N, P and Cu in natural waters? There was not a simple answer due to the fact that the EPA breaks up Florida's water into many categories. Marine, Fresh, Predominately Fresh, Drinking and such. The easiest to read data came from this site on drinking water contaminates and their Action Limits. Which are the highest limits allowed before action must be taken to avoid serious health risks. Anyway here is what I found...
Nitrogen (N)- as Nitrate 2mg/L - 6/mg/L (Dr.W this is the way they wrote it!!!)
as Nitrite 1mg/L
Phosphorus (P) - 10 micrograms/L - 40micrograms/L
Copper (Cu) - 1.3 mg/L
So are you saying that they posted the concentration as 6/mg/L?--then I suggest you email and correct them!! (LOL) Additionally--I looked on the EPA website but could not find these numbers for N and P--where are they?
