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.
