Do not use this water to mix sprays or apply irrigation that will come in direct contact with the edible portion of the crop. Inspect the water source and delivery system to see if there is any obvious source of contamination. Retest the water source if you need to use the water. If the water still does not meet the standard, the water will need to be treated to meet the standard or an alternative water source that meets this microbial standard should be used. See the EPA reference for specifics on water quality and the Agricultural Water for Production Overview for how to calculate a rolling geometric mean.
