Abstract
Background: Chronic arsenic pollution is now recognised as a worldwide problem, with 21 countries experiencing arsenic groundwater contamination. It is a particularly important issue in developing countries, where groundwater is generally the preferred drinking source (as an alternative to polluted surface water). Technologies to remove or mitigate arsenic contamination of groundwater include pre-oxidation, adsorption, biological removal, and deep tubewells. Whilst technologies such as these may be effective in stable conditions (for example, at a laboratory scale), their effectiveness in real-world circumstances needs to be assessed to inform policy making.Methods: This protocol details our proposed methods for conducting a systematic review to identify, appraise, and synthesise evidence to answer the following policy-relevant questions: a) In developing countries, are interventions to reduce the impact of arsenic contamination of groundwater on human health effective?, and b) What factors enable or constrain the effectiveness of these interventions in developing countries?
