True or False: The purpose of a well screen is to keep out birds and insects.

The purpose of a well screen is primarily to prevent sediment and larger particles from entering the well while allowing the water to flow through effectively. It is designed to filter out materials that could clog the well system or affect water quality, such as sand, silt, and gravel. A well screen functions by using a mesh or perforated material that permits water to pass but blocks larger solids from entering the aquifer.

While it might be conceivable for a well screen to indirectly deter some larger animals, such as birds, it is not intended for that purpose. The main focus of a well screen is on water quality and maintenance, rather than pest control. As such, the statement claiming that the well screen's purpose is to keep out birds and insects does not accurately reflect its true function.
