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.

|---|---|---|
| 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. | |
