It contains a link to the WMU Information Request Web Viewer and links to associated documents. This web viewer provides surface water quality, abstraction, industrial and domestic consent, pollution incident, groundwater authorisation and groundwater information, the main types of data requested.
Additional information on overall groundwater quality, groundwater dependent terrestrial ecosystems and protected areas is on the NIEA Catchment Data Map Viewer available on the Digital Download page.
