What is a Wellhead Protection Area (WHPA)?

A Wellhead Protection Area (WHPA) is defined as the land surrounding a wellfield that plays a crucial role in protecting the water supply by influencing water quality. This area is critical for safeguarding groundwater resources from contamination, as it encompasses the zones where water from precipitation and surface sources can flow into the well.

Effective management of a WHPA involves monitoring land use activities and implementing measures to prevent pollutants from entering these vital zones. This ensures that the water extracted from wells remains clean and safe for public consumption. By identifying and safeguarding the WHPA, water utilities can better protect their sources from potential contaminants that could threaten public health.

Understanding the concept of WHPA is essential for anyone involved in water resource management or public health, as it emphasizes the importance of proactive measures to maintain the integrity of drinking water supplies.
