Dalapon is a colorless liquid with an acrid odor sold as sodium or magnesium salt. Dalapon is an herbicide used to control grasses in a wide variety of crops, including fruit trees, beans, coffee, corn, cotton and peas. It is also registered for use in a number of non-crop applications such as lawns, drainage ditches, along railroad tracks, and in industrial areas. The major source of dalapon in drinking water is runoff from herbicide used on rights of way.
Some people who drink water containing dalapon well in excess of the maximum contaminant level (MCL) for many years could experience minor kidney changes.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
