Well Water in Philadelphia County: What to Test and Why

Your well water comes from a mixed underground layer of sand, gravel, and clay called the Atlantic Coastal Plain aquifer. This layer sits beneath Philadelphia County and holds water in the spaces between the grains. It formed thousands of years ago from sediment deposited by ancient water and weather.

Lead, manganese, and iron dissolve from the minerals in this sandy and clayey rock as water moves through it slowly underground. The rock itself contains these metals naturally. Chloride and sulfate also come from the rock minerals, and some may come from road salt and other human activity that seeps down into the ground.

Your water is very hard and mineral-rich. You will see white crusty buildup on faucets and inside pipes and appliances. Iron stains your sinks, toilets, and laundry rust-orange. Soap does not lather well, and your skin and hair feel sticky after washing.

Lead, manganese, iron, and other contaminants in Philadelphia County wells exceed EPA health standards. This is a serious situation that demands immediate testing. Your family's drinking water needs professional evaluation right away.

Long-term exposure to lead damages the brain and kidneys, especially in children. Iron and manganese stain sinks, toilets, and laundry rust-colored or brown. The extreme hardness and sulfate levels create thick white scale on fixtures and shorten the life of water heaters and appliances. High sodium can affect people with heart or kidney conditions.

Get your well tested through a state-certified lab immediately. A comprehensive minerals and metals panel typically costs $200–400 and will show exactly what you're dealing with. Your results will guide which treatment system works best for your family's specific water problems.
