Picloram, a synthetic organic chemical, is a crystalline organic solid with a chlorine odor. Picloram is used in salt form as a systemic herbicide for controlling annual weeds in crops, and in combination with 2,4-D or 2,4,5-T against perennials on non-croplands for brush control. The major source of picloram in drinking water is herbicide runoff. Picloram does not adhere to soil and has been found in ground water.
Some people who drink water containing picloram well in excess of the maximum contaminant level (MCL) for many years could experience liver problems.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Picloram levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Picloram levels were detected in your water sample but do not exceed the maximum contaminant level.
