Have a well? We've got you.

Is well water safe to drink?

It can be, but only a test tells you. Nobody checks a private well for you, so the owner has to. The CDC says to test every year for coliform bacteria, nitrate, total dissolved solids and pH. The testing guide points you to your state lab.

Are well records public, and how do I find mine?

Yes, most states keep the drilling record, called a well log, as a public record. Type your address into the free well record lookup and we search the official records in most states. If none comes up, we name the state office that keeps them.

How deep is my well?

The well log lists the total depth, the casing size and the water level. With no record, check the casing for a well tag, your closing papers or the driller. A well pro can also measure it with a weighted tape. More in how deep is my well.

How often should I test my well water?

At least once a year for coliform bacteria and nitrate. Test again right away after a flood, after any work on the well or pump, or when the taste, color or smell changes.

How much does a well water test cost?

It depends on the state and the tests. The Florida Department of Health says county testing is usually $20 to $30 per sample. Ask your county health department first, because many test private wells at low cost.

Why does my well water smell like rotten eggs?

The smell is hydrogen sulfide gas, often made by sulfur bacteria in the well or in the water heater. It is mostly a nuisance, but a smelly well is worth testing for coliform too. The rotten egg smell guide shows how to tell where it starts.

Why do I have low water pressure or no water from my well?

A sudden drop usually points at one part: a pressure tank that lost its air, a worn pressure switch, a broken line or a failing pump. The free pump troubleshooter walks you through each check.

How do I disinfect my well?

Mix a measured disinfectant, pour it down the well, run it to every tap, let it sit overnight, then flush. Use the amounts on your plan and follow the product label. Retest for bacteria 7 to 14 days after. The step-by-step guide covers each step.

What if bacteria come back after I treat the well?

Repeat the whole treatment, because old wells can need several rounds. The coliform guide says what to check if it keeps coming back, such as a loose cap or a cracked casing.
