West Tyrone water supply ‘at risk’ from slurry pollution

RECENT ammonia spikes in the River Derg catchment area pose a ‘significant risk’ to the water supply in West Tyrone.

That’s according to NI Water which says it’s had to shut down water production at a local treatment works to protect the water supply.

The source of the raised level of ammonia may be agricultural slurry and the matter is being investigated by The Northern Ireland Environment Agency (NIEA).

Roy Taylor, NI Water catchment manager explains,: “In recent weeks, there have been concerning raised levels of ammonia, a source of which may be agricultural slurry, particularly in the River Derg, leading to shut downs of the local Water Treatment Works.

“During the closed season, farmers should ensure that slurry is well contained and there is no risk of it ending up in our watercourses through accidental leaks, spillages or overflows from slurry storage and effluent tanks. This can lead to the Water Treatment Works having to be shut down to protect drinking water quality for our customers. This loss of water production then results in reduced water storage in reservoirs, posing a significant risk to the public water supply to our customers in the area.

“We want to protect the local water supply at all costs, particularly in light of the current winter weather and thaw conditions forecasted for early next week. Removing nutrients from our water is also difficult and expensive but is essential to provide the high quality drinking water we all expect.”

The Northern Ireland Environment Agency (NIEA) is currently investigating increased pollution and have on-the-ground resources in areas of concern like the Derg catchment, to understand the sources of ammonia nutrients in drinking water catchments. The public are encouraged to report any suspected pollution to the NIEA Water Pollution Hotline on 0800 8070 60, which is available 24 hours a day, 365 days a year.
