Regulated contaminants — legally enforceable limits
Arsenic▸
0.00325 mg/L
MCLlegally enforceable
What is it?
A naturally occurring element found in rock and soil. Gets into drinking water through erosion of natural deposits or runoff from industrial and agricultural sources.
Why it matters
Long-term exposure is linked to increased risk of skin, bladder, and lung cancer. There is no safe level for arsenic — the MCL of 10 µg/L balances health protection with treatment feasibility.
What to do
If your water is near or above the limit, a reverse osmosis filter certified to NSF/ANSI 58 removes over 90% of arsenic. Point-of-use filters at the kitchen tap are effective and affordable.
What the research says
Multiple peer-reviewed studies have found congenital heart defects including atrial septal defects at concentrations as low as 0.0005 mg/L — 20x below the US federal limit.
Barium▸
0.00343 mg/L
MCLlegally enforceable
What is it?
A naturally occurring metal found in mineral deposits. Enters water through erosion of natural deposits or discharge from drilling and metal refining operations.
Why it matters
At high levels, barium can cause increased blood pressure. Levels well below the MCL of 2 mg/L are not a health concern.
What to do
No action needed at typical detection levels. Barium is rarely found near its MCL in treated drinking water.
WHO recommendation
Sodium▸
24.4 mg/L
WHO guidelineinternational, unenforced
What is it?
Naturally present in most water sources. Also increases from road salt, water softeners, and natural mineral deposits.
Why it matters
There is no federal MCL for sodium. The WHO suggests a guideline of 200 mg/L for people on sodium-restricted diets. For most people, sodium in water is a small fraction of dietary intake.
What to do
If you're on a sodium-restricted diet and your water is above 20 mg/L, talk to your doctor. For most people, no action needed.
