- Definition
- A narrative or other textual description of the screening, casing, and/or finishing of a water well.
- Description
- A well screen is system of mesh screening or holes designed to allow water to enter a well or borehole without undue loss of flow while excluding sand, silt, and other geologic material. A well casing is a tubular structure placed in the drilled hole to maintain the physical opening from the underground water source to the surface, and also to insulate the passage of water from either loss or pollution in the intervening strata. The casing extends above the surface and protects against surface contaminants entering the water supply by its height and some form of covering.
