Simazine

GENERAL INFORMATION
Simazine is an organic white solid. Simazine is used as a pre-emergence herbicide used for control of broad-leaved and grassy weeds on a variety of deep-rooted crops such as artichokes, asparagus, berry crops, broad beans, citrus, etc., and on non-crop areas such as farm ponds and fish hatcheries. Its major use is on corn where it is often combined with AAtrex. Other herbicides with which simazine is combined include: paraquat, on apples, peaches; Roundup or Oust for non-crop use; Surflan on Christmas trees; Dual on corn and ornamentals. The major source of simazine in drinking water is herbicide runoff.

HEALTH EFFECTS
Some people who drink water containing simazine well in excess of the maximum contaminant level (MCL) for many years could experience problems with their blood.

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.
