Well Water in Erie County: What to Test and Why

Your well water comes from fractured rock layers that are not limestone or sandstone in the usual sense, but rather mixed older rock containing various minerals. Water moves through cracks and small spaces in these rocks to reach your well. This mixed rock type holds water throughout Erie County.

Arsenic, iron, and manganese dissolve naturally from the rock minerals into your groundwater. These metals are part of the rock itself and release into water as it sits in contact with these materials underground. High sodium and sulfate levels also come from minerals within the rock layers. The fractured nature of these rocks allows groundwater to pick up these dissolved minerals over time.

Your water is extremely hard, with iron at 420 parts per million and sulfate at 25,000 parts per million. You will see rust-colored staining on fixtures and laundry, and a metallic or bitter taste in the water. These mineral levels require treatment through a whole-house system to protect pipes, appliances, and your family's health.

Arsenic exceeds EPA health standards in Erie County well water, and you need to know this now. Iron, manganese, lead, radon, and other minerals also exceed safe drinking water limits. The high urgency level means your family's health depends on testing your well right away.

Long-term exposure to arsenic can damage your kidneys and increase cancer risk. Iron and manganese at these levels will stain your sinks, toilets, and laundry orange and brown. Your water will taste metallic and smell bad. The extreme hardness means thick white scale will build up inside pipes and appliances.

Get a certified lab test through a state-certified Pennsylvania laboratory as soon as possible. A comprehensive metals and minerals panel costs $200–400 and will tell you exactly what is in your water. A whole-house treatment system combining filtration and water softening can address multiple contaminants at once.
