Allowable Atrazine Watershed Concentrations for Maryland 

Based on a CE-LOC level of 9.7 ppb, fields in watersheds predicted to containing an atrazine concentration of between 9.7 ppb and 45.4 ppb atrazine will need 3 mitigation points. Watersheds in with concentrations at or above 45.4 ppb will need 6 mitigations points.
