(November 14, 2017) - NACWA provided input to EPA this week on the registration reviews of indoxacarb, a pesticide used in pet flea control products.  Products containing indoxacarb can be washed into the sewer system directly, or can transfer to household and other surfaces, and then be washed into the sewer.  Indoxacarb can potentially pass through wastewater treatment plants, which are not designed to remove insecticides, and have high toxicity in the aquatic environment. 

NACWA requested in its November 13 comments that EPA evaluate the implications of indoxacarb use in pet flea products, and consider all available alternatives.  The direct use of indoxacarb in sewer lines and manholes should also be evaluated.  NACWA referenced the detailed compilation of recent research related to indoxacarb submitted by the Bay Area Clean Water Agencies (BACWA).  

NACWA members with concerns or comments about pesticide impact on wastewater utilities should contact Cynthia Finley.
