An inquiry into health concerns at Hanson Cement’s Padeswood plant in Wales cost almost GPB500,000 (EUR630,000).

Concerns by residents living near the cement works prompted a study by the Welsh government which lasted for two years. No links between the factory and levels of cancer and other illnesses were found, the report concluded last year.

The Hanson Cement Investigation Response Team said the total cost of the investigation had been estimated at more than GBP480,000. It involved at least 80 members of staff from seven organisations, and 13,000 hours were spent working on it.

Hanson Cement said it was delighted with the outcome of the study and would take on board recommendations by the investigation’s chairman about improving communications with the local community to rebuild trust and explore any concerns that some residents feel may not have been resolved. 

Speaking to the BBC, a Hanson spokesperson said: "We believe it has been carried out with thoroughness and integrity and we hope it offers our neighbours the reassurance they have nothing to fear from our operations.”
