Lead & copper — tested at your tap
Copper
0.022 mg/L
Action levellegally enforceable
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.
Disinfection byproducts
HAA5
37 µg/L
MCLlegally enforceable
What is it?
Another group of disinfection byproducts formed when chlorine reacts with natural organic matter. HAA5 measures the five most common species.
Why it matters
Long-term exposure above the MCL of 60 µg/L (0.060 mg/L) is associated with increased cancer risk. Like THMs, the MCL is based on a running annual average.
What to do
Activated carbon filters can reduce HAA5. If your system consistently approaches the limit, a reverse osmosis filter provides more complete removal.
TTHM
56 µg/L
MCLlegally enforceable
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
Chloramines
2 mg/L
MRDLlegally enforceable
What is it?
A longer-lasting disinfectant formed by combining chlorine with ammonia. Used by many utilities because it maintains residual protection further into the distribution system.
Why it matters
Same MRDL as chlorine (4 mg/L). Chloramines are toxic to fish and dialysis patients must use special water treatment. For general consumption at normal levels, not a health concern.
What to do
If you have a fish tank, use a dechloraminating water conditioner. Standard carbon filters remove chloramines more slowly than chlorine — look for catalytic carbon filters if chloramine taste bothers you.
