In an attempt to better serve you, we have reviewed our files to ensure we have the most recent and accurate information possible. Our review has revealed that we do not have any information regarding how your residence receives its water. We are hopeful that you will take a moment to help us keep our records current. Please indicate the type of water service by circling the appropriate entry below and return this letter no later than in February 27, 2009, in the self addressed stamped envelope provided. If you receive your water from a private well, please let us know the location as it relates to your home by providing two measurements from the foundation to the well in the space provided and let us know if the well is used for domestic, lawn and garden, or agricultural use. See example below. Thank you in advance for your cooperation. Any questions can be addressed to the South Windsor Environmental Health Officer, Robert De Vito at 860-644-2511, extension 248.

For your information, 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 compound found in gasoline ne in your well y 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). Please note; the sampling frequency of your well, as requested by the CT DEP, is quarterly. Therefore,the next sampling event is scheduled for May 2008. 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 DEP at 860-424-3947 or Robert Deptula, the Environmental Health Officer for the Town of South Windsor,at 860-644-2511 ext.248.
