Pesticide levels are of concern at Limerick treatment plants


TWO water treatment plants, supplying more than 16,000 people, remain on the Environmental Protection Agency’s corrective action list due to high levels of pesticides.

“Great care should always be taken to protect drinking water supplies wherever the use of pesticides is deemed necessary, especially when using grassland weed control products containing substances such as MCPA. , fluroxypyr and 2,4-D. These and other substances have been detected in drinking water supplies in Ireland. If there is no threat to public health, the levels detected sometimes exceed the legally permitted limit value for pesticides in drinking water, which is set at an extremely low value (equivalent to a drop in a swimming pool).
