Lead Information

History of Lead in Plumbing
Lead pipes were commonly used in homes built in the early 20th century as lead was a less expensive and more durable option than iron. Concerns about lead poisoning contributed to the creation of the Environmental Protection Agency’s (EPA) Safe Drinking Water Act (SDWA) in 1986. The SDWA prohibited the use of pipes, solder, or flux that were not “lead-free” in public water systems or plumbing in facilities providing water for human consumption. At the time "lead-free” was defined as solder and flux with no more than 0.2% lead and pipes with no more than 8% lead content.

In 1991, the EPA published the Lead and Copper Rule (LCR) which regulates the concentration of lead and copper permitted in public drinking water by regularly sampling at the consumer’s tap. The LCR established an action level of 15.0 parts per billion (ppb) for lead based on the 90th percentile level of tap water samples. This means that no more than 10 percent of samples can be above the action level. The action level is the concentration of lead in tap water which, if exceeded, triggers treatment or other requirements which a water system must follow. If lead levels are found above the action levels, it does not signal a violation but can trigger additional requirements.
