Does boiling remove lead?

No. Boiling does not remove lead and can slightly concentrate it as water evaporates. Use a filter certified for lead removal, such as one meeting NSF/ANSI standards.

Should I test even if my pipes look fine?

Yes. Lead solder, brass fixtures, and fittings can release lead even when pipes look normal. Only a laboratory test can confirm lead levels.

How to Test Your Well Water for Lead

Lead in private wells typically leaches from household plumbing and fixtures. This guide covers how to test correctly and interpret the results.

Quick Answer

Lead in well water usually comes from corrosion of household plumbing, solder, and brass fixtures rather than from groundwater itself. Have a state-certified laboratory test a first-draw sample. For public systems the EPA lead action level is 0.015 mg/L, and the health goal is zero because no amount of lead is considered safe.

Where lead comes from

Groundwater rarely contains lead naturally. Most lead enters drinking water as corrosive water dissolves lead from older pipes, lead solder, and brass fittings. Homes built before 1986 are more likely to have lead-containing plumbing.

Public vs. private standards

The EPA lead action level of 0.015 mg/L under the Lead and Copper Rule applies to public water systems. Private wells are generally not federally regulated, but the action level and the health goal of zero are useful reference points for well owners.

How to test for lead

1Request a lead sample kit from a state-certified laboratory.
2Collect a first-draw sample after water has sat in the pipes for at least 6 hours, such as first thing in the morning.
3Follow the lab’s instructions precisely, since collection method strongly affects the result.
4Consider a second sample after flushing the tap to compare and locate the source.
5Review the certified report and compare against the 0.015 mg/L reference.

Lead is especially harmful to children

Lead exposure is linked to developmental and neurological harm in infants and young children and to other health effects in adults. There is no safe level, so act on any detectable lead.

If lead is found, use a certified point-of-use filter rated for lead removal for drinking and cooking water, flush taps before use, and consider replacing lead-containing plumbing. Never rely on look, taste, or smell, since lead is undetectable to the senses.
