Glyphosate Herbicide in Drinking Water Roundup

halfway “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.  Glyphosate is a non-selective herbicide used on many food and non-food crops as well as non-crop areas such as roadsides. When applied at lower rates, it serves as a plant growth regulator. The most common uses include control of broadleaf weeds and grasses hay/pasture, soybeans, field corn; ornamental, lawns, turf, forest plantings, greenhouses, and rights-of-way.

Rather, it is intended to inform consumers of some of the possible health effects associated with glyphosate in drinking water when the rule was finalized. In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur. These non-enforceable health goals, based solely on possible health risks and exposure over a lifetime with an adequate margin of safety, are called maximum contaminant level goals (MCLG). Contaminants are any physical, chemical, biological or radiological substances or matter in water.

The MCLG for glyphosate is 0.7 mg/L or 700 ppb. EPA has set this level of protection based on the best available science to prevent potential health problems. EPA has set an enforceable regulation for glyphosate, called a maximum contaminant level (MCL), at 0.7 mg/L or 700 ppb. MCLs are set as close to the health goals as possible, considering cost, benefits and the ability of public water systems to detect and remove contaminants using suitable treatment technologies. In this case, the MCL equals the MCLG, because analytical methods or treatment technology do not pose any limitation.

The Phase V Rule, the regulation for glyphosate, became effective in 1994. The Safe Drinking Water Act requires EPA to periodically review the national primary drinking water regulation for each contaminant and revise the regulation, if appropriate. EPA reviewed glyphosate as part of the Six Year Review and determined that the 0.7 mg/L or 700 ppb MCLG and 0.7 mg/L or 700 ppb MCL for glyphosate are still protective of human health.” (EPA 2015)

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.  We have partnered with a national testing laboratory to provide a cost-effective alternative that also includes trace metals, volatile organics, and other organic chemicals.   For more information, please visit our Testing Testing and Evalatuion Protal 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 the new package offers a much lower price to both water treatment professionals and homeowners.
