The A.O. Polymer manufacturing site is located in Sparta Township, New Jersey. This facility created special polymers, plastics, and resins. It was also used for reclaiming spent solvents. The facility's poor waste handling led to serious contamination of the ground. It also contaminated the water in the ground with volatile organic compounds. The site has been a threat to the Allentown aquifer, which provides drinking water to over 5,000 people. Initial clean ups started with getting rid of old drums and contaminants from their original disposal area. The company took them and decided to dispose of them elsewhere, thus not fixing the problem. Primary cleanups of the site were ongoing as of 2008. The EPA (Environmental Protection Agency) has been using water pumps to remove contaminants from the water in the ground. A soil extraction system has been put at their disposal to remove harmful contamination within the soil as well. All wells in the affected areas have been closed.
