Irish Water writes to homes in Greencastle 04.10.18

IRISH Water is to write to homes and businesses on the public water network in parts of Donegal including Greencastle where the drinking water quality is not as good as it could be. However, customers should note that water is still safe to drink.
Irish Water will outline what they are doing in the Cashilard, Creeslough, Glenties-Ardara, Greencastle, Owenteskna-Kilcar, Letterkenny and Milford-Letterkenny public water supplies where all schemes have issues with elevated levels of THMs and some have issues with cryptosporidium or high turbidity.
In Greencastle, where there are issues with elevated levels of THMs and high turbidity in the water, Irish Water will be changing the supply so in future customers will be supplied from the East Inishowen Public Water Scheme. These works are scheduled to be complete by early 2019.
In Letterkenny, where there are issues with elevated levels of THMs and ineffective barriers against cryptosporidium, the treatment plant is being upgraded and these works are due to be completed by mid-2019.

Elevated levels of THMs: All public water supplies need to be disinfected to make sure the water is safe to drink. Chlorine is used by Irish Water to disinfect drinking water. If you drink water that has not been properly disinfected, there is a risk of serious and possibly life-threatening illness.
An effect of using chlorine is that chemical compounds called trihalomethanes (THMs) can form over time. This happens when chlorine reacts with natural organic matter (tiny remaining particles of dirt, twigs, leaves and so on) in the water.
Irish Water is taking action to remove the risk of THMs forming in affected water supplies by improving the treatment plant and the water distribution network.

Poor turbidity removal: Turbidity is a measure of the cloudiness of water. Certain water supplies can be prone to increased levels of turbidity after heavy rain, or because algae has grown in the water source or because material such as sediment in the water mains has been disrupted. While turbidity can affect the look, taste and smell of drinking water, it is safe to drink. It simply means there is an operational problem at the water treatment plant.

Speaking about the public information campaign, Irish Water’s Water Compliance Specialist Dr Pat O’Sullivan said: “Irish Water has worked closely with the Environmental Protection Agency to identify the public water schemes that need a plan or action to improve their water treatment. We are prioritising our investment in these treatment plants. Providing safe, clean drinking water for all in Co Donegal is our first goal.
“Everyone we are writing to in Donegal has access to drinking water that is safe to drink. We monitor and test our supplies on a continuous basis and if this monitoring indicates a potential water quality issue we consult with the HSE. If there is any potential risk to public health from the drinking water supply we inform the public immediately. If anyone has any questions or concerns they should contact Irish Water.”
