“Water from a supply containing high levels of toxic chemicals has been pumped into the homes of more than 1,000 people, the Guardian can reveal.

Cambridge Water has admitted it removed a supply containing four times the regulatory limit of perfluorooctane sulphonate (PFOS), which was being blended with other supplies to provide water to the homes of customers in south Cambridgeshire, in June last year. But the 1,080 customers living in Stapleford and Great Shelford were never informed that they had been exposed. The company has not revealed how long the water had been tainted.

…The aquifer supplying the affected houses, close to Duxford airfield, was found to have PFOS levels at almost 400 nanograms per litre (ng/l) of water – four times the Drinking Water Inspectorate’s limit.

It said it was ‘unable to guarantee a blend below 100ng/l for our customers at all times and … previous samples taken from the same area have shown PFOS levels below 100ng/l.'”…
