What is the minimum distance required for public water supply lines from the edge of a surface application spray area?

The minimum distance required for public water supply lines from the edge of a surface application spray area is established to prevent potential contamination of the water supply. In situations where surface wastewater is applied, it is crucial to maintain a separation distance sufficient to minimize the risk of pathogens and pollutants from entering the public water supply.

A distance of 10 feet is considered adequate to provide a safety buffer. This buffer allows for protection against possible spray drift or runoff that could occur during or after the application process. By adhering to this separation distance, public health and safety are prioritized, minimizing the chances of waterborne diseases and ensuring the integrity of the public drinking water supply.

In contrast, smaller distances like 5 feet do not provide enough of a safeguard, while much larger distances such as 50 feet or 100 feet may be overly cautious and impractical. Maintaining the standard of 10 feet effectively balances safety with operational feasibility.
