A whole class ban on PFAS? It took over 60 years to gather enough information for PFOS to be globally banned. It was a further 10 years to have enough proof to ban cancer causing PFOA. Can we afford to wait to find out if the remaining 10,000 are safe? We asked @RobertBilott

The Environment Agency hope to get chemical firms to fund clean up of pollution from the PFAS they produced. Historically, applying the 'polluter pays' principle has been a very mixed bag 🧵

The EU is currently developing a wastewater treatment plan where manufacturers of chemicals & cosmetics would have to fund their clean up at wastewater treatment plant. But the EU is a huge market for those companies so they're in a stronger negotiating position than the UK.

When we interviewed Oliver Loebel of EurEau, he was clear - removing PFAS pollution is difficult, expensive & energy intensive. Far better to prevent PFAS pollution in the first place.

The River Wye is being choked by a cocktail of ammonia, nitrogen & phosphate, seething in waters stripped of the shade of woodland, wetland & water crowfoot, a new study commissioned by @WUFoundation & carried out by @cardiffuni using eDNA finds. 🧵1/8 Image
In fish, ammonia "damages the gills' ability to absorb oxygen turning them an angry red or, even, bleeding. By that stage, it's game over" @Petex70 of the @AnglingTrust told us. Ammonia in the Wye may be 1 reason for a steep decline in salmon numbers. 2/8

The Wye has been plagued by increasingly frequent algal blooms, devastating wildlife. We spoke to @gillieUB (who made this video), who told us the river is fairly clear until around where it meets the Ithon - site of many intensive poultry farms. 3/8

Sharks devouring cocaine flung overboard during raids, fish populations crashing as exposure to the levels of oestrogenic chemicals found at sewage outlets feminises male fish, @DrAlexFord on the flood of pharmaceuticals engulfing aquatic creatures.🧵

Of treating sewage 3 times, Dr Ford says, "we...have tertiary treatment in the UK but it's still not up to the specifications where it wld get rid of a lot of the pharmaceutical drugs...that can be done -& it involves a lot more money in our infrastructure- we can remove them... Image
"...So, that's a decision to be made by society - whether we do want to invest more in our wastewater infrastructure." 3/6 podcasts.apple.com/gb/podcast/coc…

Forestry Service orders private equity firm to stop pumping water from California's San Bernardino mountains. Blue Triton acquired water rights when they bought a bottled water firm. Since then, pumping increased, but 94-98% isn't bottled but used for "undisclosed purposes"🧵1/5 Image
"undisclosed" in that, although the Forestry Service has repeatedly asked what the water is being used for, the firm don't seem keen to tell them. Conservationists say the increased pumping has reduced the creek to "a trickle". Article @ByIanJames 2/5

latimes.com/environment/st…
Last year, @mslaurabliss reported on a pattern of corporations acquiring bottled water firms - gaining rights to pump water - an increasingly scarce resource. The article was part of @Bloomberg's terrifying "water grab" series, on corporate buy ups of water resources. 3/5 Image

Toxic Tees: joint 1st place for most chemically polluted river went to the Tees. A government review found a mass die off of crustaceans in the Tees may be down to an unidentified disease. Could the toxic mix of chemicals we uncovered for this @itvnews piece also play a part?🧵
. @CHEMTrust & @AlistairBoxall explain mixing chemicals can raise their toxicity levels - a chemical that, on it's own, might only be toxic at high levels, when mixed with other compounds, cann become so at much lower amounts.

In last night's @itvnews piece, featuring our trawl of chemical pollution data, @AlistairBoxall outlines to @MartinStewITV the toxic brew of chemicals he routinely finds in waterways - a mix which amplifies harm, similar to mixing drinks. 3/6

We're barraged with chemicals in all parts of our daily lives. A new report from @CHEMTrust reveals:-
- combinations of multiple substances can cause specific chemicals to act as toxins at much lower levels
- current regulation takes little or no account of this cocktail effect🧵 Image
