Well Water in Chester County: What to Test and Why

Your well draws water from an underground basin of mixed rock and sediment left from an ancient sea that covered this region millions of years ago. This basin sits between harder rock layers on either side, creating a pocket where water collects and flows slowly underground. The rocks here include sandstone, shale, and other materials that hold water in their tiny spaces.

Arsenic, lead, and manganese come straight from the rock itself as water dissolves these metals over time. Radon seeps from uranium naturally present in the stone. Sulfate and chloride build up as water sits in contact with minerals in the rock and as salt from roads and farm use seeps down. Your groundwater has no natural protection from these contaminants because the rock is porous enough to let surface pollution reach the water.

Your water carries very high amounts of sodium and sulfate, making it extremely salty and hard. Iron is also present at high levels, which stains sinks and laundry rust-orange and leaves mineral buildup on pipes and fixtures. This water will corrode metal plumbing and require treatment before daily use.

Your Chester County well water exceeds EPA health standards for several serious contaminants including lead, arsenic, radon, and manganese. These metals and radioactive gas are present at levels that require immediate action. This is a high-urgency situation affecting your family's health.

Long-term exposure to lead damages children's brains and nervous systems and harms kidneys in adults. Manganese exposure can affect the nervous system over time. Radon in water releases radioactive gas into your home when you shower and use hot water. Beyond health risks, your water shows extreme hardness and high iron, which stain sinks and laundry orange-yellow and leave thick white scale on fixtures and pipes.

Call a state-certified laboratory today and request a comprehensive metals and minerals panel, which costs between $200 and $400. A basic screen for bacteria and nitrate runs $50 to $100 but will not catch all your contaminants. Install a whole-house treatment system combining filtration, ion exchange, and aeration to address lead, manganese, radon, and hardness together.
