Review existing literature to estimate the likely concentrations of OPFRs in source waters used for drinking water supplies and identify any specific OPFRs that are likely to be most prevalent. Using existing literature, establish the likely removal efficiencies of OPFR compounds through different water treatment processes in order to evaluate whether there is a risk of OPFR occurrence in drinking water. Report the findings of the literature review study in a final project report. ## CPV classification Research services Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/d4009ccb-f1e4-4a58-abfb-ed415bc4479a) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
