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.

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).
