What is a well seal?

The well seal, also known as a sanitary seal, is an important component of a water well that protects the well from surface water contamination and provides protection for the upper part of the well.

How do you seal a drilled well?

A sealant, such as cement grout or bentonite clay, should be poured along the outside of the casing to the top of the well. The well is capped to prevent surface water from entering the well. Submersible pumps, located near the bottom of the well, are most commonly used in drilled wells.

What is an annular seal in a well?

The seal consists of a mixture of cement, bentonite and sand that is placed to make a water tight seal in the annular space between the casing and the borehole wall. Most state well regulations contain a requirement for a minimum annular seal depth.

How is a well drilled?

When bedrock is encountered, drilling continues until competent bedrock is reached, generally between 10 and 20 feet. Steel casing is then installed in this hole and sealed to the bedrock. This casing seals the well from potential contaminants from surface infiltration.

How deep should a well seal be?

These regulations usually contain requirements for a minimum seal depth for different classes of wells. In California, for instance, a public water supply (PWS) system well is required to have a minimum seal depth of 50 feet while in Tennessee, requirements include a minimum of 19 feet of casing and 10 feet of seal.

What happens if a well seal is inadequate?
