Atrazine

GENERAL INFORMATION
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.

HEALTH EFFECTS
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.

Treatment options: 

TREATMENT OPTIONS
Granular Activated Carbon (GAC) or Powdered Activated Carbon (PAC) are considered the best available technologies (BAT) for treatment of many organic contaminants including organic pesticides, volatile organic compound (VOCs), and Trihalomethanes (THMs) (by-products of chlorination). Treatment can be at the tap (called point of use or POU) or the entire house.
