Recycled Water under FSMA

Recycled water that is allowed to be used for irrigation of food crops must meet state regulations and guidelines established to protect the public health. A summary of the microbial standards for irrigation with recycled water for states that have established such criteria is presented below. Recycled water meeting applicable state regulations for irrigation of food crops meets FSMA requirements for irrigation water quality.

* Only states with water reuse standards (in mid-2019) are included

** Regulation 84 is undergoing reform to allow use for food crops

*** Groundwater protection--not food crops

^ Using the California standards for uses of recycled water

^^ Land disposal--not food crops

^^^ Food crop irrigation allowed with no contact and no spray irrigation

~ These standards are for graywater reuse

~~ Also Enterococci 4 and 9 CFU/100 mL

~~~ Also E coli 11/35 colonies/100 mL and Enterococci 11 and 24 colonies/100 mL
