The recently published report on water quality in Ireland, 1995-97, concluded that the overall condition of Irish waters remains satisfactory and compares favourably with the position in other European countries. The report did, however, record further increases in the levels of eutrophication, due primarily to excessive inputs of phosphorus to rivers and lakes.
While sewage and industry are significant contributors to the overall phosphorus load to freshwaters, agriculture has been identified as the single biggest contributor to the eutrophication problem. Phosphorus losses from agriculture arise from inadequate waste management at farmyard level and from leaching and run-off from land, particularly following the spreading of slurries or the use of chemical fertilisers containing phosphorus.
Since 1997 my Department has been pursuing a comprehensive, integrated strategy to tackle all sources of eutrophication. This is already beginning to show evidence of some improvements in water quality. The strategy is underpinned by the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus) Regulations, 1998, which I made in July last year. The regulations set clear targets for reducing phosphorus levels in rivers and lakes within a ten year timeframe.
The strategy is being supported by the Department's major £1.5 billion programme of investment in sewage infrastructure facilities throughout the country in the ten year period to 2005. This programme lays particular emphasis on the provision of phosphorus reduction facilities where a need is indicated in this regard. My col league, the Minister for Agriculture and Food, has substantial initiatives under way to tackle phosphorus inputs from agriculture, including the rural environment protection scheme and the proposed new control of farm pollution scheme.
Following recent initiatives by the detergent industry, it is estimated that the phosphorous load from detergents will be reduced by about 50 per cent by mid 2000 with further reductions to follow thereafter. The strategy I am pursuing is designed to reduce phosphorus inputs from all sources. In this way, I am committed to achieving the improvements in water quality which are demanded by the phosphorus regulations.
