What the testing found
Measured levels from EPA violation records, compared to the federal limit (MCL). The black line marks the legal limit.
Copper
1.45× the federal limitShort-term: nausea/vomiting/cramps; long-term: liver/kidney damage. Leaches from copper plumbing, worse with corrosive water.
Radium
Over limitRadioactive; combined radium MCL 5 pCi/L. Bone cancer risk with long-term exposure. Naturally occurring in groundwater.
Lead
Within federal limitNo safe level. Damages developing brain/nervous system in children; linked to lower IQ, kidney and cardiovascular harm in adults. Usually enters water from corroding pipes/solder, not the source.
Filters certified to clean up your water
Your water shows Copper, Radium, Lead. A reverse osmosis system handles the most of this in one unit — these three are independently certified for the most of your contaminants (not marketing claims):

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level.
