Regulated contaminants — legally enforceable limits
Arsenic▸
0.002 mg/L
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▸
0.19 mg/L
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.
Combined Radium▸
0.1 pCi/L
What is it?
The combined measurement of radium-226 and radium-228 — naturally occurring radioactive elements found in some groundwater, especially in the Midwest and Great Plains.
Why it matters
Long-term exposure above the MCL of 5 pCi/L increases cancer risk, particularly bone cancer. Radium is most common in deep groundwater wells.
What to do
Ion exchange water softeners can reduce radium. Reverse osmosis is also effective. If your system uses groundwater and radium is detected, a point-of-use filter adds a layer of protection.
Fluoride▸
0.65 mg/L
What is it?
Naturally occurring mineral, also added to many water systems to prevent tooth decay. The MCL (4 mg/L) is much higher than the typical added amount (0.7 mg/L).
Why it matters
At levels near the MCL, long-term exposure can cause skeletal fluorosis (bone pain and tenderness). The secondary standard of 2 mg/L triggers a required public notice about dental fluorosis risk in children.
What to do
Levels below 2 mg/L are within the range considered safe. If above 2 mg/L, children under 9 may be at risk for dental fluorosis — talk to your pediatric dentist.
What the research says
Multiple peer-reviewed studies have found lower IQ in children and potential thyroid disruption at concentrations as low as 1.5 mg/L — 3x below the US federal limit.
Gross Alpha▸
1.4 pCi/L
What is it?
A screening test that measures total alpha radiation from all radioactive elements in water — including radium, uranium, and radon.
Why it matters
The MCL of 15 pCi/L protects against long-term cancer risk from radiation exposure.
What to do
No action needed at typical detection levels. If near the MCL, reverse osmosis and ion exchange filters can reduce radioactive contaminants.
Nitrate (as N)▸
2 mg/L
What is it?
Comes from fertilizer runoff, septic systems, and erosion of natural deposits. One of the most common groundwater contaminants in agricultural areas.
Why it matters
Nitrate above 10 mg/L can cause "blue baby syndrome" (methemoglobinemia) in infants under 6 months — it interferes with blood's ability to carry oxygen. Adults can tolerate higher levels.
What to do
If you have an infant on formula and your water is above 5 mg/L, consider using bottled water for formula preparation. Boiling water does NOT remove nitrate — it concentrates it.
What the research says
Multiple peer-reviewed studies have found neural tube defects, preterm birth, and low birth weight at concentrations as low as 5 mg/L — 2x below the US federal limit.
Uranium▸
4 µg/L
What is it?
A naturally occurring radioactive metal found in some groundwater, especially in granite and volcanic rock formations. Common in the western US.
Why it matters
The MCL of 20 pCi/L (or 0.030 mg/L) protects against kidney toxicity and cancer risk. Uranium is both a chemical toxin and a radiological hazard.
What to do
Reverse osmosis and ion exchange filters can reduce uranium. If your system uses groundwater in a uranium-bearing geology, a point-of-use filter is good protection.
Lead & copper — tested at your tap
Copper▸
0.61 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.
Lead▸
0.0019 mg/L
What is it?
Lead in drinking water almost always comes from your home's plumbing — not from the water source or treatment plant. Lead pipes, solder, and brass fixtures can leach lead, especially if water sits in pipes for hours.
Why it matters
There is no safe level of lead exposure. Even low levels can harm children's brain development, and cause kidney and blood pressure problems in adults. The action level of 15 µg/L is a regulatory trigger, not a safety threshold.
What to do
Run your tap for 30 seconds to 2 minutes before drinking, especially in the morning. Use cold water for cooking and formula — hot water leaches more lead. A filter certified to NSF/ANSI 53 for lead removal is the most reliable protection.
What the research says
There is no safe level of lead exposure. Lead crosses the placenta and causes preterm birth and cognitive impairment in children at blood lead levels below 10 µg/dL.
Disinfection byproducts
TTHM▸
1 µg/L
What is it?
Formed when chlorine used to disinfect water reacts with natural organic matter. Includes chloroform, bromoform, and related compounds. The trade-off: disinfection prevents waterborne disease, but creates these byproducts.
Why it matters
Long-term exposure above the MCL of 80 µg/L (0.080 mg/L) is associated with increased cancer risk and possible reproductive effects. The MCL is based on a running annual average, not a single sample.
What to do
If your system is near or above the limit, an activated carbon filter (including pitcher filters like Brita) can reduce THMs. Running water for a minute before drinking also helps, as THMs are volatile and dissipate.
Disinfectants — MRDL
Chlorine▸
0.8 mg/L
What is it?
Added intentionally to kill bacteria and viruses. A chlorine residual in your tap water means the disinfection is still active through the distribution system — this is by design.
Why it matters
The MRDL of 4 mg/L is the maximum allowed. Typical levels are 0.5–2 mg/L. Chlorine at normal levels is not a health concern — the disease risk from untreated water is far greater.
What to do
If you don't like the taste, let water sit in an open pitcher for 30 minutes or use an activated carbon filter. Both remove chlorine taste and odor.
