Lead Control - Cause and Effect |
Studies by the Environmental Protection Agency (EPA) indicate that high levels of lead can occur either from short-term, heavy exposure or from long-term, lower exposures. The more lead there is in the body, the more severe the health effects. |

The following is a chart that demonstrates the potential for faucets manufactured prior to 1997 to leach lead into the supply water. |

Source-EQI These levels were found to repeat approximately every 2 hours after a flush. Brand name and price are not indicators of the potential lead leaching level. The EPA produced a lead-free faucet and fixture standard prohibiting fixtures with more than 8% by weight of lead in fixture. The "Lead Free" rule went into effect in August of 1996. New fixtures with 8% lead still leach lead and copper. EPA maximum contaminant level for lead is 15 parts per billion. EPA legal limit for lead content in the construction of a faucet manufactured after August 1996 is 8%. EPA requires public water supply piping systems testing above 15 ppb to treat the pipe by placing a protective film on the pipe, valves and fitting surfaces with a chemical treatment in order to reduce the water's corrosiveness and mineral content. |
