The Environment Agency works with the water companies, local authorities and others to investigate any sources of contamination and to improve water quality at local bathing waters.
-
Bathing water quality may sometimes be affected by storm, emergency and surface water outfalls. Storm overflows may operate during and following periods of heavy rainfall when the sewer system becomes overwhelmed by the amount of surface water entering. The overflows prevent sewage from backing up pipes and flooding properties. Abbey Mill CSO storm discharge outfall is located just below the weir at the northern end of the bathing water.
-
Modern sewerage systems have two separate systems, one takes foul sewage to sewage treatment, the other takes rainwater runoff through surface water drains to rivers, lakes and the sea. Misconnections occur when waste water pipes are plumbed into surface water drains instead of the foul water sewerage system. This can give rise to pollution when the waste water is discharged directly to the environment through the surface water drain. For example, a washing machine or toilet may be incorrectly plumbed so that it discharges to the surface drain rather than the foul sewage drain.
-
There are no active pollution risk forecasts made at this bathing water. However any bathing water has the potential to be affected by a pollution incident and if this occurs a pollution risk warning with associated advice against bathing will be issued on this website.

There are no treated sewage discharges in the area of the bathing water. Harrogate North Sewage Works discharges into Oak Beck approximately 10km upstream of the bathing water.
-
Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar.
-
The bathing water site lies to the southeast of the town of Knaresborough. The catchment above Knaresborough is mostly rural with several small centres of population including Pateley Bridge and Summerbridge and is primarily a mixture of low intensity livestock farming. The catchment above Birstwith, 11 miles above the bathng water, lies within the Nidderdale Outstanding Area of Natural Beauty. The surrounding hillside contains a number of old mine workings and is scattered with springs. Gouthwaite Reservoir towards the headwaters of the catchment is a designated Site of Special Scientific Interest (SSSI).

Seaweed (macroalgae) and phytoplankton (microscopic algae) are a natural part of the marine and freshwater environment. Below we note whether these have been recorded in quantities sufficient to be a nuisance.
-
The majority of sewers in England are “combined sewers” and carry both sewage and surface water from roofs and drains. A storm overflow operates during heavy rainfall when the sewerage system becomes overwhelmed by the amount of surface water. The overflow prevents sewage from backing up pipes and flooding properties and gardens. An emergency overflow will only operate infrequently, for example due to pump failure or blockage in the sewerage system.
-
Heavy rain falling on pavements and roads often flows into surface water drains or highway drains, ending up in local rivers and ultimately the sea. The quality of bathing water may be adversely affected as a result of such events.
-
It is the Environment Agency's role to drive improvement of water quality at bathing waters that are at risk of failing higher standards. It is natural for water to run off the land to the sea. Water quality at a bathing water is dependent upon the type and area of land (the catchment) draining to the water and the activities undertaken in that catchment.
-
Discharges from sewage treatment works have improved substantially in England since the 1980s.
