Chemical hazards in drinking-water - glyphosate and AMPA

Glyphosate and AMPA are considered in the WHO Guidelines for Drinking-water Quality. You can link from here to:

The Guidelines for drinking water quality also consider for individual chemicals:

Background

WHO received a communication that research by the Geological Survey of Denmark and Greenland had found glyphosate levels in groundwater five times higher than the EC/EU allowed level for drinking-water. The use of glyphosate in Denmark has doubled in the last five years. WHO’s current position on glyphosate is that its health-based value is orders of magnitude higher than concentrations normally found in drinking-water, so that the establishment of a numerical guideline value is not deemed necessary. Glyphosate is being re-evaluated by JMPR, and a report will be available early in 2005.

Progress to date

The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2004) agreed to review the occurrence data on glyphosate as a first step. The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) examined the occurrence data and decided that there was no need to change the decision not to set a formal guideline value for glyphosate.
