Private water supplies represent a valuable source of potential sites for inclusion within the Environment Agency’s Groundwater Quality Monitoring Network (GQMN). At these locations, it may be possible to collect samples from a number of points within the water supply system, such as from a storage tank or a tap at some distance from the source. It is important to consider the likely changes in water chemistry within the supply system in order to provide guidance on sampling location and network site selection.
A literature review sought to identify the common design of these water supply systems, and the key factors likely to influence changes in water chemistry. This information was then used to identify six sites at which a sampling exercise would be undertaken. This aimed to evaluate the water chemistry within the supply system, and hence the likely impact of different sample collection points on resultant groundwater quality analyses.
