The tests were conducted utilizing Environmental Protection Agency (EPA) approved methods and a copy of the laboratory report is enclosed. The laboratory results indicate no presence of MTBE or any other gasoline compound in your well water. As you know, the tests conducted on your drinking water well are part of an ongoing groundwater investigation being conducted under the direction of the Connecticut Department of the Environmental Protection(CT DEP). Again, thank you for your patience and cooperation. If you have any questions regarding the test results or the investigation in the area or if you notice changes in the taste, smell or appearance of your water, please feel free to call the toll free ExxonMobil Information Line at 1-877-346-0302 or, if you prefer, we suggest you contact Kevin Neary with the CT DEP at 860-424-3947 or Robert DeVito, the Environmental Health Officer for the Town of South Windsor, at 860-644-2511 ext. 248. 7Sily Matthe R.
