Glyphosate is an herbicide that is regulated under the Safe Drinking Water Act. It is an ingredient in Roundup, a widely used herbicide, as well as more than 700 other products for sale in the United States.
While the United States classified glyphosate as non-carcinogenic when it was last reviewed in 1993, the World Health Organization published a study in March 2015 that indicates glyphosate is a probable carcinogen. Since the new study was released, there have been many questions asked regarding the safety of glyphosate. According to The Ecologist (June 12, 2015), several countries have banned or restricted use of the weed killer, including France, Columbia, Sri Lanka and El Salvador. In addition, many garden centers across the globe are pulling products that contain glyphosate off their shelves as a precautionary measure to protect customers. However, Roundup remains a staple herbicide in the United States.
Testing for glyphosate previously may have been cost prohibitive for many homeowners, but National Testing Laboratories (NTL) now offers a lower-cost test for detecting glyphosate in drinking water. Typical analysis by EPA-approved methods can cost $200 to $400, but NTL’s new testing package offers a much lower price to both water treatment professionals and homeowners.
