COPIAGUE - The New York State Department of Environmental Conservation has begun testing the air quality in 13 Copiague homes over toxic-fume concerns.

The DEC says toxic chemicals from a nearby industrial site on South Strong Avenue contaminated the ground water. Officials say those solvents can work their way through the soil and evaporate into the air.

For privacy reasons the state agency is not releasing which homes may be affected, but a spokesperson says the concentration of chemicals is relatively low and doesn't affect drinking water.

Officials are currently testing the air in the first five homes and say they expect to have the results within a few weeks.
