Groundwater Resources Development

Project narrative

Undertake a Hydrogeological review of available information to determine the suitability of developing a further groundwater resource to an existing well field on the caravan park site.

Supervision of the drilling and installation of a new production well field on-site with well installations in locally important slate and schist bedrock aquifers and one well in overlying groundwater bearing gravels.

Undertake a series of step pumping tests on all wells with a 3-day constant rate pumping test on two chosen production wells.

Pumping test information was used to provide sustainable yields of the two production wells to meet site water demands.

Chemical and microbiological groundwater quality sampling and interpretation of laboratory analytical results with recommendations for precautionary water treatment.

Preparation of a hydrogeological assessment report outlining the findings of the production well field drilling and testing with recommendations on safe yields and water treatment requirements.

This project involved examining the existing well field on the caravan park and developing a hydrogeological assessment to examine the potential of providing a more sustainable potable water supply for the site.

Suitable well locations were located on-site taking into account suitable distances from surrounding potentially pollution sources and from potential saline intrusion from the Irish Sea.

A drilling and testing programme has identified suitable sustainable yields to meet the site requirements. Detailed water quality analysis indicated very good groundwater quality with limited water treatment required to provide a potable resource to meet the current and future needs of the caravan park.
