MEETING OF LUCAN AREA COMMITTEE

MOTION NO. 2

MOTION: Councillor P. Gogarty

"That the Chief Executive respond to recent media reports that the Liffey‘s high pollution, which they say will impact on blueway plans, is being exacerbated by pollution in the Griffeen; that measures be looked at to alleviate this and in the meantime that drinking water be made available for dogs being walked in Griffeen Valley park, initially near the dog run."

REPORT:

Water quality samples are collected from the River Griffeen at regular frequency from two locations, Amyler Road and Lucan Village, by Water Services staff of South Dublin County Council.

Results show good water quality at Amyler Road sampling point and moderate water quality at Lucan Village for the relevant nutrient parameters of ammonia and phosphorus. The results are typical for a stream of its size as it flows from upland rural to and through lowland urban areas accumulating nutrients, particularly in the large urban area of Lucan.

South Dublin County Council has performed a significant amount of water quality sampling and environmental analysis of the River Griffeen over the past three years and is currently assessing the possibility of using Integrated Constructed Wetland technology to purify water discharging from specific culverts to the river in the area near the dog run. Planning for the installation of such wetlands follows a certain process, which takes time and includes utilising lands in the park to site the wetlands - discussion of which has commenced.
