Abstract:
The NRA has a duty, under the 1991 Water Resources Act, to monitor controlled waters. Controlled waters include estuarine and coastal waters out as far as the three nautical mile limit. The coastal baseline survey was introduced in 1992, and extended nationally in
1993, as a means of meeting this objective. The surveys provide a means of collecting background levels of contaminants to provide a baseline of water quality in the coastal zone. These surveys have taken the form of simultaneous boat and airborne surveys in Spring, Summer and Autumn and a boat survey in Winter (when weather conditions render the aerial surveillance difficult), around the coast of England and Wales. The four NRA survey vessels (Water Guardian, Sea Vigil, Coastal Guardian and Vigilance) are used to perform the boat work and a chartered light aircraft used for the aerial surveillance work.
