***CONCERNS ABOUT RADON
The highest Radon levels for our system was 1,884 pCi/L, taken on May 28, 2004. Radon is found in the soil and bedrock formations and is a water soluable, gaseous by-product of Uranium. Most Radon is released to the air, moments after turning on the tap. Only about 1-2 percent of Radon in the air comes from drinking water. The USEPA is proposing setting lower standards for public drinking water. The State of Maine currently recommends follow-up action (or treatment) for Radon levels in drinking water above 20,000 pCi/L. Breathing Radon released to air from tap water increases the risk of lung cancer over the course of your lifetime. If you seek more information about Radon, please contact this office or the State Drinking Water Program and request a Radon Fact Sheet.

Source water assessment
" Sources of drinking water include rivers, lakes, ponds and wells. As water flows either on the surface or through the ground, it dissolves naturally occurring minerials and raidoactive materials and can also accumulate substances resulting from human and animal activity. the Drinking Water Program (DWP) has evaluated all public water supplies as part of a source water protection program. The assessment includes geology, hydrology, land use, water testing information, and the extent of the lands ownership or protection by local ordinance to see how likely our drinking water is to being contaminated by humans in the future. Assessment results are available at public water suppliers, town offices, and the DWP. For more information, contact the Drinking Water Program at 287-2070."
