TMDL Monitoring Guidelines
Farmers may check out a Turbidimeter from the Imperial County Farm Bureau for 2 week increments. The Turbidimeter is easy to use and will tell the farmer whether or not their drain water is in compliance with TMDLs. Turbidimeters (model 2100 P) may also be purchased at www.hach.com.
