QUESTION NO.9

QUESTION: Councillor H. Farrell

To ask the Manager for information on specific environmental priorities for rivers in the Lucan, Palmerstown and North Clondalkin areas during 2026.

REPLY:

 There are 3 rivers in this area, the Camac, the Liffey and the Griffeen.

Sampling/monitoring measures

• In 2026, routine monthly sampling will occur in each river including EPA testing, along with any pollution investigation samples.
• We take approximately 16 samples per month to monitor various parameters such as BOD, Suspended Solids, Phosphates and pH.
• Additional sampling of Griffeen in relation to DURL project will also continue to ensure water quality.
• We are in the process of organising a second micro invertebrate survey at the Griffeen ICW to see how this project has improved biodiversity in the area. Funding application has been submitted.
• The team also plans on increasing work regarding Section 4 Discharge Licenses; this is critical in commercial areas around Clondalkin where development is occurring.
• Continue to sample sites with existing section 4 Licenses and investigate other discharges in the commercial areas.

Misconnection assessments

• Subject to resources, misconnection assessments in areas around Lucan and the Italian Ambassadors former residence.
• Prioritise misconnection assessments in residential areas around Oakcourt Drive. 
• We also want to conduct commercial misconnection assessments this year, potentially in business parks like Fonthill and Park West.
• Misconnection works to be organised subject to staffing levels and training available.

Pollution Investigations

• The team will conduct pollution investigations in the area as required.
• Samples will be taken during the pollution investigations where needed.
• Close out complaints as promptly as possible and do follow up visits if required.
