Abstract

This paper deals with the outcomes of the tests and studies conducted by Nepal's Department of Water Supply and Sewerage (DWSS) especially focussing on 'Terai Tube wells Arsenic Testing and Mitigation Program' launched with assistance from UNICEF. It presents the results of tests for arsenic and microbiological contamination of 3896 tube wells by field test kits in 20 districts of the terai region and confirmation laboratory testing of 1772 tube well water samples. Altogether 5 percent of tube wells had more than Nepal's Arsenic Interim Guideline Value of 0.05 mg arsenic per litre (estimated exposed population 550,000) and 29 percent of tube wells had more than the WHO Arsenic Guideline Value of 0.01 mg arsenic per litre (estimated exposed population 3.19 million).
