Cancer-linked toxin still present in Greencastle water
A CANCER-linked toxin is still present in the water in Greencastle, and plans to replace the supply may be 12 months behind schedule.
Ten months ago the Inishowen Independent revealed that there were unsafe levels of the chemical toxin trihalomethanes (THMs) in the drinking water supply in Greencastle.
Back then we informed you that Irish Water recorded two exceedances of THM in the Ballymacarthur plant, one in November 2014 and another in July 2015.
Both exceeded the safety guidelines set out by the EU.
The legal limit for THMs in drinking water in Europe is 100 microgrammes per litre of water, but this limit has been exceeded on six more water quality tests since then.
The toxic compounds are formed when organic material such as peat in soil, reacts with chlorine in the water.
A number of scientific experts have linked excessive levels of THMs in water to liver, renal and bladder cancers; while other studies have failed to provide a clear link.
