Poor water quality restricts Thames wildlife - ZSL
Teams of volunteers surveyed river banks, using an app to geotag, photograph and assess outfalls.

Pollutants dumped in the Thames due to misconnected plumbing 

Nearly a third of London’s outfalls show signs of contamination, meaning raw sewage and other pollutants are ending up in the Thames, putting wildlife at risk. This is according to a comprehensive survey led by the Zoological Society of London (ZSL).

Teams of volunteers surveyed river banks, using an app to geotag, photograph and assess outfalls - drains that send surface water to rivers - for evidence of pollution.

ZSL said there were signs of contamination, including sewage fungus, in 356 of the 1,177 surveyed locations. In addition, 269 locations had definite pollution problems. This equates to an average of two to three polluting outfalls for every kilometre of river surveyed.

The data suggests a large number of homes and businesses across London are sending waste from toilets, sinks and washing machines into rivers, due to misconnected plumbing. ZSL said pollution is degrading the ecological health of rivers, limiting the amount of wildlife they can support.

“Approximately 600km of rivers and streams flow through Greater London into the tidal Thames,” explained Joe Pecorelli, project manager of ZSL’s estuaries and freshwater team.

“Together, these waterways represent an invaluable habitat for wildlife, from eels and water voles, to kingfishers and dragonflies – but a history of poor water quality, badly-designed flood defences and adaptations for navigation has prevented many of them from achieving their full ecological potential.”

ZSL is calling for a “significant increase” in investment to address the misconnections in London’s plumbing systems. Home and business owners across the capital are also being urged to have their plumbing checked for misconnections.

Debbie Leach, chief executive of London’s waterways charity Thames21, added: “There is a massive environmental accident happening across London, and it is devastating our rivers. But because it is happening day after day, it isn't making the news. That has to change.”

Vets save premature penguin chick

News Story 1
 Vets have saved a tiny Humboldt penguin chick after her egg was accidentally broken by her parents. Keepers at ZSL London Zoo were shocked to find the chick, named Rainbow, still alive and rushed her straight to the Zoo’s on-site veterinary clinic.

It was a little way to go until the chick should have hatched, so the process was touch and go. Vets removed bits of shell from around the chick with tweezers until she could be lifted out and placed in a makeshift nest.

Rainbow is now in a custom-built incubation room where she spends her days cuddled up to a toy penguin. Keepers will hand-fed Rainbow for the next 10 weeks until she is healthy enough to move to the penguin nursery.

BVA infographic to help shoppers understand farm assurance schemes

An infographic to help members of the public understand farm assurance schemes has been produced by the BVA. The infographic outlines BVA’s priorities for animal welfare and shows whether or not the schemes address these priorities in their standards.

BVA president John Fishwick said: “The infographic is not intended to be a league table but to allow people to understand what aspects of animal health and welfare are addressed by assurance schemes so that they can decide which scheme best aligns with their own individual preferences and priorities."
