This document sets out the required european and national standards for drinking water quality.

The purpose of this letter is to inform NI Water Ltd of the regulatory changes under the Environmental Better Regulation Act (Northern Ireland) 2016 which amended the Water and Sewerage Services (Northern Ireland) Order 2006 (the Order) to transfer the regulation of the qualit

The European Water Framework Directive (2000/60/EC) (WFD) requires the status of groundwater management units (groundwater bodies) within each river basin to be determined as ‘good’ or ‘poor’.

All groundwater bodies in Northern Ireland were classified in 2014-2015 to establish whether they are at good or poor status utilising monitoring data from the past six years (2009 to 2014).

The General Quality test’s overall aim is to assess if the impact of groundwater pollution is sufficiently widespread to compromise the use of the groundwater resource either currently or in the future.

The process of classifying Groundwater Dependant Terrestrial Ecosystems (GWDTE), as defined above, is laid out below. Explanation of the method is given below, with specific detail given to the origin and processing of data required for the implementation of the method.

The saline intrusion test assesses if an abstraction of groundwater or set of abstractions are likely leading to the intrusion of poorer quality water into a water body.

Surface Water Chemical classification checks whether chemicals, namely phosphorus, contained in the groundwater baseflow (to the surface water body) contribute to status failure of that surface water body.

The Surface Water Quantitative classification test evaluates whether an abstraction or set of abstractions are likely to be leading to a deterioration in status of a surface water body.
