Pollution on Mill Pond 29 July – photo by Kari Silvester
There was yet another pollution incident on the River Ravensbourne, at Mill Pond, Glassmill Lane on 29 July. This appeared to be sand, like an earlier incident, and which covered most of the pond surface. This was reported to the Environment Agency (ref: 1544086) by a Friends member. The long term environmental impact of this latest incident is currently uncertain.The pollution has subsequently been moving down stream. We await the result of this latest EA investigation.
Recently there have been an increased number of such incidents, some very serious. These incidents are the result of either unauthorised mis-connection of waste water outlets (e.g. sinks), or the illegal emptying of waste into local surface water drains or water courses. The Environmental Agency, working with Thames Water, consider this a pollution ‘hot spot’, and the Mill Pond is being closely monitored by local volunteers and reported to the EA. If you spot pollution in our local rivers please report to the Environment Agency on 0800 807060
After much work by contractors, and expense, the oil spill appears to have been cleared. We await feedback from the Environment Agency on their investigation of this incident. It is pleasing to see the ever optimistic moorhens are sitting on eggs again. Let us hope that they are successful this time.

Early last Friday morning (31 March) a serious pollution incident was spotted on the Mill Pond, Glassmill Lane, Bromley BR1. This was immediately reported, by one of our members, to the Environment Agency. A large quantity of oil was covering the water and its margins.
Since then Thames Water contractors have been busy on site installing temporary booms to restrict the wider contamination of the River Ravensbourne, as well trying to remove the oil. To date at least one tanker full of oil has been sucked up. Unfortunately oil has also contaminated both the mud and the island. This will be extremely difficult to clean. The impact on the fish and other invertebrates in the water has yet to be determined. Already several nesting Moorhens have died as a result of this pollution, and the RSPCA are continuing to monitor the situation.
The Environment Agency and Thames Water investigation, of the cause of this pollution and identification of the culprit, is ongoing. For more on this area go to Mill Pond and Ravensbourne restoration
This historic Mill Pond is important both for its heritage and environmental features. It is an important nesting site for ducks and is also visited by grey herons, kingfishers, etc. Part of the River Ravensbourne catchment, we were already working with Thames21 and other stakeholders, to access grant funding to enhance this important space.
