Jason, totally agree with you about the reasons for the demise of the Barbel fishing.
As regards the water colour, I have just read the NRA Cherwell Consultation Report that you posted the link too. Page 91 seems to confirm the effect that the Coffee Processing Plant and its waste precedures have had on the discolouration of the Cherwell. An excerpt of that page below:
ISSUE 4: EFFLUENT DISCHARGE FROM BANBURY SEWAGE TREATMENT WORKS
Overview 5.17 Trade effluent from the Kraft General Foods coffee manufacturing plant is discharged to sewer and is eventually treated at Banbury Sewage Treatment works. The effluent from the coffee manufacturing process is highly coloured, and the sewage treatment works processes have very little impact on the colour. Consequently the effluent discharged from Banbury STW is highly coloured, and causes noticeable discoloration of the Cherwell. The problem is not so much one of pollution, but of aesthetics and has caused numerous complaints from river users. At present there is no colour standard on the consent conditions for Banbury, however when the 'Aesthetics' window component of the General Quality Assessment scheme is introduced, this discolouration is likely to be highlighted further.
Strategies and Management Options 5.18 The NRA should review the consent and consider the application of a colour standard for the discharge.
5.19 TWUL should consider possible treatment options for reducing the coloured component in the effluent. This is likely to incur significant costs and it may be that TWUL would refuse to accept the effluent if a colour component were introduced to the consent.
5.20 Kraft General Foods should consider opportunities for partial or complete on-site treatment of the effluent stream/colour removal. It should be recognised that this is likely to incur significant investment and it is believed that such investment may well make the plant uneconomic. Implementation 5.21 The NRA should convene a working group with Kraft General Foods and TWUL to establish economic and environmentally acceptable options for the discharge.
You then get down to Appendix A.page 2 which outlines the NRA’s Strategic Objectives for the Cherwell. See excerpt below:
A.6 The NRA’s Strategic Objectives regarding water quality are:
• to maintain waters that are already of high quality;
• to improve waters of poorer quality;
• to ensure all waters are of an appropriate quality for their agreed uses;
• to prosecute polluters and recover the costs of restoration from them;
• to devise charging regimes that allocate the costs of maintaining and improving water quality fairly and provide incentive to reduce pollution.
I’m left wandering, did the NRA actually execute the objectives.
Hmmmmmmm.............!!
