Good Water Quality=Safe Water

Our comprehensive list of water related microbiological organisms will help you characterize water quality for regulatory requirements or peace of mind. We use methods approved and developed by EPA and APHA. Assure your Ag water safety or maintain regulatory compliance with our convenient and prompt water analysis. 

The FDA has once again extended the ag water compliance dates in order to have time to make adjustments they feel may be necessary to the rule. Currently there are no details on how long the current extension will be or what changes to the rule will be made. We will do our best to keep you informed as more information becomes available. For the time being growers should continue to perform any ag water testing they were currently required to do for their Global GAP or other food safety audit requiremnts.

Water sampling for the Produce Safety Rule under FSMA is required to begin in 2018. At that time growers will have 4 years to complete their water quality profile. Currently the only testing method explicitly approved in the rule is EPA 1603. This is a different method than is currently used by most laboratories to test Ag water due to the greatly increased labor costs in running samples with this method. Cascade Analytical is prepared to switch all Ag water samples to this method in 2018 when sampling for FSMA must begin if no other method is allowed by that time. In the meantime, the current methods used will satisfy all GAP audit requirements currently in place.

The Produce Safety Alliance, who has been tasked with the creation of the training cirriculum for the Produce Safety Rule, recently released a letter covering the topic of Ag water sampling compliance dates and test methods. That letter can be found linked below.
