Farm Country Water: Why Nitrates Top the List
Kent County Well Check: What's Really Under That Well Cap?
Many Kent County farmhouses still use water systems that predate modern well codes. Choose the setup that looks most like yours.
Hand-dug well
How to recognize it: A wide opening, often 2 to 4 feet across, lined with brick, stone, or concrete rings. Usually shallow.
Main risks: Surface water and bacteria seep in easily, plus nitrate from nearby fields and flooding.
Tests we suggest first: Bacteria and nitrate first, then again after heavy rain.
Older drilled well
How to recognize it: A narrow steel casing with the cap at or below ground level, and often no records.
Main risks: Cracked or buried casing and loose caps can let in bacteria.
Tests we suggest first: Bacteria and nitrate, plus a look at the wellhead during our free visit.
Well in a pit or basement
How to recognize it: The wellhead sits below ground in a pit, or inside a basement.
Main risks: Pits collect runoff and small animals, a common source of bacteria.
Tests we suggest first: Bacteria first, and nitrate if the pit is near fields or septic.
Spring or springhouse
How to recognize it: Water is collected from a natural spring on the property.
Main risks: Open to surface contamination, with quality that can change with the weather.
Tests we suggest first: Bacteria and nitrate, tested more than once a year.
Cistern
How to recognize it: Rainwater or hauled water stored in a tank.
Main risks: Bacteria, debris, and acidic water that can corrode plumbing.
Tests we suggest first: Bacteria and pH, plus lead and copper if plumbing is older.
Modern drilled well
How to recognize it: Casing stands 12 or more inches above ground with a sealed sanitary cap.
Main risks: The lowest risk of the group, though iron, hardness, and nitrate still show up.
Tests we suggest first: Annual bacteria and nitrate, plus iron and hardness.
