Bridging the GAPs: Approaches to Treating Water On Farms

Chemical injection versus treatment with a pesticide device

Through the course of this publication, we’ve compared chemical treatments and a pesticide device. This is a summary comparing those two types of technologies.

Antimicrobial Activity

Chemical Injection Downstream activity past the point of injection • Helps control biofilm formation in irrigat ion delivery systems Treatment with a Pesticide Device UV light or filter- no downstream activity • Only inactivating microorganisms at the point of treatment Ozonation- downstream activity

EPA Approval

Chemical Injection Must be EPA labeled for treating agricultural water • Will need supporting scientific studies that validate the activity of the system as you intend to operate it Treatment with a Pesticide Device No EPA approval needed • Will need supporting scientific studies that validate the activity of the system as you intend to operate it

Implementation

Chemical Injection Must demonstrate agricultural water is of adequate sanitary quality • Monitoring • Corrective actions Treatment with a Pesticide Device Must demonstrate agricultural water is of adequate sanitary quality • Monitoring • Corrective actions

Interaction with Other Compounds

Chemical Injection Most will oxidize organic and inorganic materials • Fertilizers • Pesticides • Herbicides Treatment with a Pesticide Device UV light and ozone can have negative reactions with
