LeadMetalsZero ppb15 ppbAction level7/16/2024
Your body
EPA has set a health goal of zero for lead because no safe level of exposure is known. In children, low-level lead exposure has been linked to lower IQ, learning and attention problems; in adults, to raised blood pressure and kidney effects. Pregnant women and young children are most at risk.
Your home & appliances
Lead itself does not damage plumbing, but its presence is a sign of corrosion: water chemistry that dissolves metal from pipes, solder, and fixtures.
What it is
A metal that usually gets into tap water from lead service lines, lead solder, and older brass fixtures inside buildings, not from the water source itself. Homes built before 1986 are more likely to have lead plumbing.

Your body
Exposure to certain PFAS, such as PFOA and PFOS, has been linked to effects including changes in cholesterol, reduced vaccine response in children, lower birth weight, and increased risk of some cancers (EPA; Fenton et al., 2021). In 2024, EPA set drinking water limits for several PFAS.
Your home & appliances
PFAS do not affect plumbing or appliances.
What it is

According to EPA, infants under six months who drink water with nitrate above the federal limit could become seriously ill (blue baby syndrome). Research has also examined links between long-term exposure and other health effects.
Your home & appliances
Nitrate does not harm plumbing. It can indicate that surface water or septic waste is reaching a well.
What it is
A form of nitrogen from fertilizer, manure, and septic systems that can soak into groundwater. It is a common concern in farming areas, including much of the Eastern Shore.

According to EPA, long-term exposure above the federal limit has been linked to liver, kidney, or central nervous system problems and an increased risk of cancer. Studies have associated long-term exposure to chlorination byproducts with bladder cancer.
Your home & appliances
Trihalomethanes do not affect plumbing. They can also be inhaled during hot showers.
What it is
A group of four chemicals (chloroform, bromodichloromethane, dibromochloromethane, bromoform) that form when chlorine reacts with natural organic matter in water. Levels are usually higher at the far ends of a distribution system and in warm months.
Exactly as reported
- Dibromochloromethane: 0.00062 mg/L (level found) · MCL 0.1 · health goal 0.06 · violation: NO · sampled 2023Note: Dibromochloromethane is one of the four trihalomethanes regulated together as TTHM. Values shown as printed.
