“The site of a former film studio has been investigated as a possible source of ‘forever chemicals’ found in groundwater, a water company said.

Affinity Water said the film and photographic processing that took place at the Denham Film Studios in Buckinghamshire may be linked to the perfluoroalkyl and polyfluoroalkyl substances (PFAS) detected in Blackford Water Treatment Works in Hillingdon.

The groundwater once supplied 20 million litres (20,000 kiloliters) of drinking water a day to parts of London."
