Atrazine is a white, crystalline solid organic compound. Atrazine is a widely used herbicide for control of broadleaf and grassy weeds. Effective in 1993, its uses were greatly restricted. The major source of atrazine in drinking water is runoff from herbicide used on row crops.
Some people who drink water containing atrazine well in excess of the maximum contaminant level (MCL) for many years could experience problems with their cardiovascular system or reproductive difficulties.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Atrazine levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Atrazine levels were detected in your water sample but do not exceed the maximum contaminant level.
