Protecting your drinking water

Protecting your drinking water at its source to ensure a high-quality drinking water supply.”

It is widely recognised that protecting drinking water at it's source is the No.1 method of ensuring that a high quality is achieved

The National Federation of Group Water Schemes (NFGWS) is actively involved in promoting source protection amongst the group water sector in Ireland. Presently Phase II of the new “Drinking Water Source Protection Pilot Project” is underway. This pilot will involve source protection planning for both groundwater and surface water sourced Group Water Schemes (GWSs).

Stranooden GWS has been selected as the pilot site for the surface water aspect of the project. Ross Mac Donald is the current Source Protection Officer appointed by Stranooden GWS to oversee the project. His Focus is:

  • Maintaining a Source Protection Plan
  • Implementing Phase 3 of The pilot project. 

The scheme abstracts its water from White Lough (also known as Baird Shore), where it’s then pumped to its water treatment plant in Corcaghan. Eight groundwater supplied GWSs, located in Co. Roscommon and Co. Westmeath have also been included in this national initiative, with this aspect of the work being conducted by Tobin Consulting Engineers, the Geological Survey of Ireland (GSI) and The NFGWS.

Mitigation Details

WHAT IS MCPA?

Monaghan County Council are the supervisory authority for all private GWSs in Co. Monaghan.

As part their role, Monaghan Co. Co. take a number of water samples each year from the Stranooden GWS’s treated drinking water network.

During this testing, MCPA was in detected in certain water samples taken in 2017 and 2018. MCPA is a selective herbicide, commonly used in Ireland as a rush killer, but is also found in domestic herbicide products. Since March 2018, Stranooden GWS have carried out weekly sampling on the numerous streams and rivers that flow into White Lough to try and determine which parts of the catchment may be contributing mostly towards the problem.

Why Stranooden GWS?

There are a number of reasons why Stranooden GWS was selected to pilot the surface water aspect of the project. As part of Phase I of the project, each GWS throughout the country that abstracts water from a lake source had their lake catchments delineated. A lake catchment simply means the area of land that drains into a river and its tributaries which then flows into a lake.

 

Home Use of MCPA

What we have found that Home users have also been using MCPA. 

Scouring in Greenans Cross Aghabog and more...

Thursday 23rd November 2023

Areas affected today are Corleck, Carn, Drumbraen, Drumgarley, Mountain Hill, Greenans X, and Lissarrily

Localised texts will be sent for each area when your water will be effected

Scouring effecting the above areas will begin on Today Scouring will continue all this week.

 

Stranooden Catchment Management Plan 

The overall objective of the project is to develop an Integrated Catchment Management Plan that will result in the improvement of the scheme’s drinking water source (i.e. White Lough).

It is hoped that as a result, the levels of nutrients, coliforms and herbicides detected within the lake will be reduced. If this can be achieved, Stranooden GWS envisage that the drinking water we supply to our members will be of a higher quality in terms of both potability and safety.

In order to achieve this, Stranooden GWS believe that interaction with the communities that live and work within the lake’s catchment will be key. Stranooden GWS staff are currently out on the ground, mapping the exact routes of the numerous streams and rivers that flow into White Lough as well as talking to the landowners adjacent to these channels. This work will continue over the next number of months.

To be successful in our approach, Stranooden GWS will not solely be focussing on agricultural pressures but will be looking at the catchment as a whole.

For example, ineffective domestic waste water treatment systems (DWWTS) may be contributing to our problem.

In 2016 the NFGWS commenced a DWWTS Education and Desludging Programme. As part of this initiative people where afforded the opportunity to sign up to have their septic tank desludged as part of a community wide bundle approach. By signing up to this scheme, participants availed of significant savings (up to 50%) on the cost of desludging. Stranooden GWS are keen to offer this service its members.

Through the development of a catchment plan specific to Stranooden GWS, it is anticipated that the findings obtained from the project will be used to develop a template and guidance for the development of source protection plans for all surface water supplied GWSs. Similarly, the learning obtained from the pilots underway in Co. Roscommon and Co. Westmeath will be utilised in the development of guidance for groundwater supplied GWSs.

Trihalimethanes

Another problem faced by Stranooden GWS in relation to our drinking water surrounds the issue of trihalimethanes (THMs). THMs are compounds which may be formed when water that is high in organic content is treated with chlorine. Given that there are high levels of coliforms present in White Lough, Stranooden GWS uses chlorine to remove these coliforms prior to the distribution to its members. Similarly, high levels of organic matter can also be present in White Lough. This combination of organic matter and chlorine has on occasion resulted in an exceedance in the THM drinking water limit. The short-term health effects of THMs in drinking water are rare, however the effect of long-term exposure is not yet fully understood. With that being said, Stranooden GWS are keen to address the issue so that it doesn’t become a long-term problem.
