Well Water in Ocean County: What to Test and Why

Groundwater in Ocean County contains iron, manganese, arsenic, lead, and human-made chemicals called PFOA and PFOS, along with chloride, sulfate, fluoride, nitrate, and radon. Multiple contaminants exceed EPA health standards, making water testing and treatment important for well owners in this area.

The sandy and gravelly underground layers that hold this county's water naturally release iron and manganese as water moves through them over time. Chloride enters from road salt and coastal saltwater intrusion near the shore. Lead leaches from older household plumbing. Nitrate comes from fertilizers and septic systems. PFOA and PFOS are industrial chemicals that have contaminated some areas through manufacturing and disposal. Radon forms naturally as uranium in the rock slowly breaks down.

Groundwater in this county is soft and not notably mineral-rich overall, though iron at moderate levels is the main aesthetic characteristic present. Iron concentrations result from the sandy aquifer naturally releasing it as water filters downward. Iron is detected in a substantial number of wells across Ocean County, making it a common feature of the local groundwater.

Wells in Ocean County commonly exceed EPA health standards for arsenic, lead, radon, nitrate, and per- and polyfluoroalkyl substances (PFOA, PFOS, and PFHXS). Arsenic and lead damage the nervous system and organs over time. Radon is a radioactive gas that increases lung cancer risk. Nitrate poses risks to infants and people with certain health conditions. PFOA, PFOS, and PFHXS are industrial chemicals linked to serious health effects including kidney and immune system problems.

County wells show moderate iron levels that can create rust-colored staining on fixtures and laundry. You may notice a metallic or unpleasant taste in the water. Iron can clog pipes and damage appliances like water heaters over time. The good news is that county groundwater is soft, so scaling from mineral buildup is not a major concern here.

Every well is different, and your well may have higher or lower contamination than what is common in the county. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel to check for all these concerns at once, which typically costs $200-400. Treatment options like activated carbon filters, radon aeration systems, or reverse osmosis can address different contaminants depending on what testing finds.
