Small Private Supplies
Small Private Supplies, involved in the provision of water to the public, are legally obliged to have Water Quality tests undertaken, outlined in the European Communities Regulations 2014 (S.I. 122 of 2014) and 2017 amendment (S.I No. 464 of 2017)
What types of tests are required?
Compliance monitoring:
Two different types of tests are required, measuring a range of parameters. These tests are titled ‘Group A parameters’ previously called ‘check parameters’ (a ‘check’ comprises some ‘microbiological’, ‘indicator’ and ‘chemical’ parameters) and Group B parameters previously called ‘audit parameters’. (‘Audit’ comprises all parameters from the Microbiological, Chemical and Indicatory categories covered in the 2017 Drinking Water Regulations). Frequency for both categories is based on volume used per day/consumers on the supply. Data from this category is returned to the EPA on an annual basis and forms part of the annual drinking water returns from Offaly County Council.
Operational Monitoring:
This category comprises E.coli, Coliform Bacteria and Colony Count @ 22°c and can change pending changes in water quality. Results are used to assess water treatment and will demonstrate if chlorine dosing is being managed effectively. Results from this category will not be returned to the EPA.

Zones of Contribution
About 80% of the drinking water supply in County Offaly comes from groundwater sources: wells, springs, boreholes. It is vitally important that these sources are protected from potential sources of pollution.
A groundwater protection scheme has been developed for county Offaly. As part of this, so called “Zones of Contribution” have been mapped for many sources in the County. This is a hydrological assessment of the land area contributing to a well or a spring source. Activities carried out in these areas need to be strictly controlled in order to prevent pollution of the source.
The Environment Section of Offaly County Council carry out assessments in the zones of contribution. The overall objective is to maintain the quality and security of our drinking water supplies.
Groundwater Protection Scheme maps and reports have been completed along with source protection reports for drinking water supplies in Co. Offaly. See link below for more information.
