Inorganic Contaminants	Units	MCLG	MCL	Average Level Detected	Range	Violation Yes/No	Typical Source of Contaminant
Lead	ppb	0	15 (AL)	122	0.0 - 230	YES	Corrosion of household plumbing system; erosion of natural deposits
				90th Percentile
Infants and young children are typically more vulnerable to lead in drinking water than the general population.  It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing.  If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested and flush your tap for 30 seconds to two minutes before using tap water.  Additional information is available from the Safe Drinking Water Hotline (800-426-4791).  Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development.  Children could show slight deficits in attention span and learning abilities.  Adults who drink this water over many years could develop kidney problems or high blood pressure.

The NH Department of Environmental Services (DES) has prepared a Source Assessment Report for the source servicing this community water system, assessing the sources vulnerability to contamination.  The result of the assessment, prepared in September 2002, are as follows.  Lake Massabesic, received four (4) high susceptibility ratings, four (4) medium susceptibility ratings, and five (5) low susceptibility ratings.  The complete Assessment Report is available for inspection at DES or the following site: http://www.des.state.nh.us/dwspp/reports/MANCHESTER.pdf.
