Do I need to chlorinate my well?

Chlorination has been used for years to eliminate bacteria, iron, and other deposits from wells. If your well tests positive for fecal coliform or E. coli, you need to chlorinate your well. The presence of fecal coliform

and/or E. coli indicate the possibility that more harmful bacteria may be present in your water.

Chlorination is also used to remove iron deposits from your well pump system. Depending on the type and quantity of the contamination, chlorination is often recommended to remove buildup. Removing buildup preserves the well pump and other associated equipment. In areas with high iron content, chlorination is recommended every 6 months.

Note: We recommend that you test your well water for E. coli and coliform bacteria a minimum once per year.

Recent FAQs

What is a well screen?

If the bottom of the well is in sand and/or gravel, the well driller may install a well screen. The well screen is a metallic cylindrical sieve-like structure which is usually attached to the bottom of the well casing or other water intake areas.

What is a pump screen?

A pump screen is a combination of a coarse stainless-steel shield and a fine screen that completely covers the pump. This disallows sand and gravel particulates from entering your water feed stream. This does slow the gallons per minute (GPM) of the pump while still allowing enough water to supply the house.
