Agricultural Water


Produce Safety Alliance

The Produce Safety Rule (PSR) requires growers to initially establish a Microbial Water Quality Profile (MWQP) for each untreated agricultural water source used during growing activities of covered produce (other than sprouts) using a direct water application method and conduct annual surveys for that water source in subsequent years. The water quality profile is based on the levels of generic Ecoli in your agricultural water. There are different requirements for agricultural water that comes from surface or ground (well) sources.
