Identifying the Sources of Listed Substances in Diffuse Inputs to Sewage Treatment Works

Price: £18  

This study aimed to establish which listed substances are present in diffuse inputs to sewage treatment works and to evaluate relative contributions. Results indicated that several heavy metals arise predominantly from domestic sewage and for these there appears to be little scope to reduce inputs. Specific organic substances or groups are identified as likely to be present in domestic, service trade and runoff inputs. Results from pilot studies provide confidence in the UKWIR/EA pollution inventory protocol predictions for metals but confirm that there is considerable uncertainty regarding estimates for inputs of organic substances. Some changes to the protocol are recommended.
