Pesticide Investigation

There is a surface water drinking abstraction point at Ballyboughlin bridge which is North of Clara, Co. Offaly. Pesticides have been detected within this supply above the drinking water limit over the last number of years, subsequently the supply was added to the EPA pesticide watch list in 2017. Due to the number of exceedances, in 2018 OCC generated a pesticide exceedance response plan to assist in identification of the source of pesticides within the drinking water catchment area.

There was just one sampling location in which a pesticide was detected above the drinking water limit (0.1μg/l), sampling location 13 detected Diflufenican-Triaz-LC- at 0.273μg/l. This sample was taken directly downstream of a horticultural nursery, whilst sampling location 14 (containing no pesticides) was taken directly upstream of the nursery. The most commonly detected pesticides within this sampling event included MCPA, Trichlopyr and Fluroxpyr.
