This month the Dublin Branch of IWT heard Alex Russell (PhD researcher at UCD) give a talk to about groundwater in Ireland. Alex gave a general overview of the quality of groundwater in Ireland (natural water chemistry and geology). In Ireland, up to 25% of drinking water supplies are sourced from groundwater, with a particular importance in rural areas where public supplies are often unavailable. However, in Ireland private wells remain unregulated for quality testing, potentially leading to significant unknown exposures to contaminated waters, including arsenic, which occurs naturally in may parts of Ireland.
Globally groundwater is a finite and precious resource, which is being used up at a far greater rate than it is being replenished. This is yet another unsustainable use of the planet's resources whih will lead to severe water shortages worldwide in the future.
