Groundwater in Kent County contains sulfate, chloride, and manganese at levels that exceed EPA health standards. These contaminant levels are concerning enough that well owners should be aware of them and consider testing.
The rock beneath Kent County naturally holds dissolved salt and sulfate minerals that leach into groundwater over time. Chloride and manganese also come from the underlying rock layers in this region, where these elements concentrate in the stone and dissolve into water as it passes through.
Groundwater in this county is very hard, driven by elevated sulfate and sodium that accumulate from the local rock. The dry climate and underlying geology combine to concentrate these minerals in the water as it flows slowly through the stone. These characteristics are widespread across wells throughout the county.
Chloride, fluoride, iron, manganese, and sulfate are found at levels exceeding EPA health standards in wells across Kent County. Fluoride at elevated levels can weaken tooth enamel and cause skeletal problems with long-term exposure. Chloride and sulfate at high levels can affect kidney and heart health, especially for people with certain medical conditions. Iron and manganese can harm the nervous system and affect organ function over time.
Wells in this county have extremely hard water, which leaves stubborn white crusty buildup on fixtures and in pipes. The water may taste salty or metallic and makes soap less effective. Very hard water shortens the lifespan of water heaters, dishwashers, and other appliances. You'll spend more money on cleaning products to remove stains and scale.
We recommend getting your well tested with a comprehensive metals and minerals panel, since multiple contaminants exceed health standards. Every well is different--yours could have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so it can be properly treated. Water softeners and iron removal systems can help address these concerns.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
