Yes. In 1991, the Environmental Protection Agency (EPA) published a regulation to control lead and copper in drinking water, known as the Lead and Copper Rule (LCR). The EPA revised the regulation in 2000 and 2007.
Congress has also set limits on the amount of lead that can be used in plumbing products. These requirements were first enacted in 1986 and then reduced to lower levels in 2011.
No. The main risk of lead in drinking water comes from old service lines leading from the water provider's water main to the individual property. Padre Dam water mains are predominantly cement pipe, ductile iron pipe and PVC with no lead pipe used in water mains. There are also very few properties within the Padre Dam service area that have lead used in the plumbing inside the property.
Unfortunately, in the Northeast and Midwest there are a number of lead service lines connecting older homes to water mains. If those pipes are exposed to corrosive water, or if water sits too long inside them, the lead could be released and may end up coming out of the tap. This appears to be the case in Flint, Michigan.
No. Padre Dam has been monitoring the drinking water for lead since the EPA's Lead and Copper Rule (LCR) went into effect in 1991. Specific homes within our service area are selected for testing every three years per EPA LCR guidelines. Water samples are collected inside each selected residence at the tap so that the customer's plumbing is tested along with the service line delivering water to the house. There are minimal lead service lines within the Padre Dam service area and Padre Dam has never taken a sample with results exceeding the allowable level set by the EPA LCR.
Padre Dam has a consistent record of either meeting or exceeding all state and federal drinking water regulations, which further highlights our commitment to providing our customers with exceptional quality drinking water.
