Infants and young children are typcially 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 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. As a general practice, you should flush your tap for 30 seconds to 2 minutes before using the tap water, if you have not used it for 4-6 hours. Additional information is available from the Safe Drinking Water Hotline at 1-800-426-4791.

Definitions
MCL Maximum Contaminant Level The highest level of a contaminant that is allowed in drinking water
MCL's are set as close to the MCLG's as feasible using the best available technology
MCLG Maximum Contaminant Level Goal The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLG's allow for a margin of safety.
MF/L   Million Fibers per liter
Action Level   The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
CFU/100 ml   Colony Forming Units per 100 milliliter
Mrem/yr Millirems per year A measure of radiation
pCi/L Picocuries per liter A measure of radioactivity

Abbreviations   Compared to
ppm Parts per million milligrams per liter One second every 12 days
