Why a seller cares

A private well means the buyer, and often their lender, will want a water test and a look at the pump. A clean test and a service record settle the question; a failed test becomes a treatment system on your side.

Part 2 of 4

A simple example

Your home is on a well. The buyer's lender asks for a bacteria and nitrate test, and the buyer's inspector checks the pump's flow rate.

Well water: a simple example
What the test findsWhat tends to follow
Clean water, good flowNothing; the report goes in the file
Coliform bacteriaA shock chlorination and a retest, a few hundred dollars
High nitrates or a weak pumpA treatment system or a pump, and a negotiation

Well water is tested, not assumed. The test is where it becomes a cost or a non-issue.

Part 3 of 4

What people get wrong

That the water tasting fine means it will pass. Bacteria and nitrates have no taste, which is why lenders ask for the lab.
