What is required to ensure the safe transportation of water used in pesticide mixing?

The requirement to ensure the safe transportation of water used in pesticide mixing emphasizes the use of an air gap from the tank. An air gap is a physical space that prevents the backflow of water into the potable water supply, which is crucial when dealing with pesticides. This practice helps to mitigate the risk of contamination, ensuring that harmful chemicals do not inadvertently enter drinking water sources.

Transporting water with an air gap maintains safety because it allows any potential pesticide residue to remain in the mixing tank rather than contaminate the water supply. This method is widely recognized as a best practice for preventing cross-connection between non-potable and potable water systems, thus safeguarding public health and environmental integrity.
