  WATER   

POLLUTION

UN SUSTAINABLE DEVELOPMENT GOAL 14

To conserve and sustainably use the oceans, seas and marine resources for sustainable development.

EU WATER FRAMEWORK DIRECTIVE 2000
‘Protection of all waters, surface waters and groundwater, in quality and quantity with a proper ecological dimension.’

UK NATIONAL POLICY STATEMENT FOR WASTE WATER

‘1.1.3-Habitats Regulation Assessment (HRA) examines the potential effects of a plan or project on nature conservation sites that are designated to be of European importance.’

March 2012

NITRATES

Urban and agricultural run-offs are the cause of eutrophication through excessive amounts of nitrogen and phosphorus entering the water. This results in algal blooms which depletes the oxygen in the seas. This is a huge threat to the protected waters in the harbours of Chichester, Pagham and Medmerry.

NATURE ENGLAND

‘New housing contributes nitrates to the water through sewage. High levels of extra human pollution are affecting protected sites.’

HUMAN WASTE

‘Sewage waste accounts for almost a quarter of all serious water incidents.’

UK Department of Environment

OFWAT The Water Services Regulation Authority

Southern Water has deliberately misreported data to us about the performance of its waste water treatments.

We have also concluded that it has failed to have adequate systems of planning, governance and internal controls

in place to be able to manage its waste water treatment works.

July 2019

Locally the capacity of the waste treatment centres is measured on a dry basis. However, due to poor drainage in the area, these pumping stations are overloaded after heavy rainfalls.

Local sewage capacity does not account for the large number of tourists who stay in the area.

MICROPLASTICS

“Plastic pollution as an unfolding catastrophe”

Sir David Attenborough

PORTSMOUTH UNIVERSITY

‘90% of microplastic contamination is filtered and collected with the sludge at waste water treatment centres which is then spread as fertiliser and contaminates the soil or returns to the water through run-off.’

Serena Consolo, Researcher, Portsmouth University

CHICHESTER HARBOUR CONSERVANCY SYMPOSIUM

‘Microplastics – 10,000 microfibres per litre recorded in the top layer of the harbour’.
