Air Force officials say a study shows that while industrial solvent wastes in north Layton groundwater exceeded a federal standard, the contamination did not appear in drinking water samples.
Hill Air Force Base environmental engineers said Friday that the concentrations in the groundwater are very low and did not recommend against using the water for irrigation.Nonetheless, money has been requested to study possible environmental and health effects, said Bob James, of the base's Directorate of Environmental Management.
He said contamination was most consistently found in agricultural field drains at depths of 5 to 10 feet. It also was seen in wells 30 to 60 feet deep.
A large layer of clay forms a barrier between the affected water and Layton drinking water.
