Limit
Lead & copper — tested at your tap
Copper
0.18 mg/L
What is it?
Leaches from copper household plumbing and pipes. Some copper is a normal part of drinking water infrastructure.
Why it matters
Short-term exposure above the action level of 1.3 mg/L can cause gastrointestinal distress. Long-term exposure can cause liver and kidney damage. At typical detected levels (well below the AL), copper is not a health concern.
What to do
If above the action level, run your tap for 30 seconds before drinking. Copper levels decrease as water flows through the pipes.
No US limit — WHO recommendation
Chlorate (7)
145 µg/L
What is it?
A byproduct of water disinfection with chlorine dioxide, and a contaminant from some herbicides.
Why it matters
No federal MCL. The WHO guideline is 700 µg/L. Chlorate may interfere with thyroid function at high levels.
What to do
No action needed at typical detection levels.
