One of two national public forums to discuss potential environmental perchlorate contamination will be held later this month in Salt Lake City.

Perchlorate contamination became an issue in Utah last year when rocket motor builder Alliant Techsystems, formerly Hercules, discovered elevated levels of the chemical in 400-foot-deep wells on its property in West Valley City.Lower levels were found at Kennecott Copper's property where officials provided employees with bottled water. Low perchlorate levels also were found in nearby drinking water wells in the Magna area, according to the Environmental Protection Agency.

Perchlorate is a man-made salt used in solid rocket fuel, in munitions and in fireworks. It is as soluble as table salt.

The Utah forum will be held in Salt Lake City, Tuesday, Aug. 25, from 8 a.m. to 5 p.m. at the Utah Department of Environmental Quality, 168 N. 1950 West, Room 101. An evening session from 7 to 9 p.m. will be held in Magna at the Magna Senior Citizens Center, 8952 W. 2700 South.

To register for one of the forums, contact the EPA Safe Drinking Water Hotline, 1-800-426-4791, between 7 a.m. and 3:30 p.m. Registration is free.
