MEETING OF LUCAN/PALMERSTOWN/NORTH CLONDALKIN AREA COMMITTEE

QUESTION NO. 14

QUESTION: Councillor G. O'Connell

To ask the Chief Executive for a report on the condition of the water in the stream in Glenaulin Park and to state when it was last tested.

REPLY:

Routine EPA Operational Monitoring sampling occurs at a number of locations on the Liffey, the Griffeen, the Camac, the Dodder and the Owendoher Rivers, under the Water Framework Directive. A number of water bodies including the Glenaulin Stream are not on the EPA Operational Monitoring list and therefore are not  sampled routinely.

The Council does take non-routing samples in other water bodies ocassionally.The Glenaulin Stream was sampled on two ocassions in 2020, in February and in March.

In February 2020 the results showed dissolved oxygen, pH, and chemical oxygen demand to be within acceptable range but there were exceedences in ammonia and phosphorus. In March, all of the parameters were within the acceptable range. 

Urban streams such as Glenaulin can be impacted by domestic misconnections, it is anticipated the tools and procedures developed in the Dublin Urban Rivers LIFE project for pollution reduction and water quality improvement will be applied to other streams in the County, including the Glenaulin Stream, when that project is completed.
