Investigation of Organic Chemicals in Sludge
This study on the occurrence of organic chemicals in sewage sludge was commissioned in response to proposed changes to the Sludge Directive (86/278/EEC) and the potential introduction of limits on organic chemicals in sludge applied to land.
An earlier study highlighted the potential risks posed by di(2-ethyhexyl)phthalate, linear alkylbenzene sulphonates, and polycyclic aromatic hydrocarbons (PAHs) but recommended that monitoring studies be implemented to augment the paucity of UK data.
In this project, samples from sixteen sludge treatment centres have been analysed for a range of compounds. PAHs have been identified as posing the highest risk of non-compliance against proposed limits. Options to mitigate the risk have been assessed. Given the prohibitive financial and environmental costs of the options, the primary recommendation was that the water industry should consider undertaking an evidence based study on the risks posed by PAHs to human health and the environment from sludge applied to land.
