Study reports mixed success in tackling water pollution

A new study has found that water quality is gradually improving in two of Ireland's largest rivers, but is deteriorating in a third.

The €6m, three-year study found that the decline in water quality in the River Liffey had halted, while the quality of the Boyne had improved and the quality of the Suir had deteriorated.

Farming was blamed for 60% of phosphorous in the water, with sewage plants, septic tanks and industrial discharges among the other named culprits.

In its final report, the Three Rivers study said:

1. Polluters should be made to pay for their actions.

2. Standards for sewage plants and discharge licences should be reviewed.

3. Farm management should be improved.

4. A special body should be established to protect Ireland's waterways.
