Untreated sewage is being dumped into the sea and rivers at 43 locations across Ireland.
That’s according to a new report from the Environmental Protection Agency which says 29 larges towns and cities around the country have failed to meet EU standards.
It suggests the problems are due to a lack of investment in infrastructure which has dropped by 40 percent, in the last decade.
The EPA report also found the building of treatment plants in many areas have been delayed by up to two years.
Meanwhile, the EPA lists Kilgarvan as an urban area where improvements are required to resolve priority issues.
It is included in a list of areas where improvements to waste water discharges were required at the end of 2015 to protect fresh water pearl mussels.
Elsewhere, Kerry doesn’t have an large area which is non-compliant with the effluent quality standards.
An upgraded waste water treatment plant was provided in Tarbert, Ballylongford and in Knightstown last year.
