ABSTRACT
ABSTRACT: Screening test has been implemented in order to survey arsenic contamination in Bangladesh since the first arsenic detection in groundwater occurred in 1993. National Policy for Arsenic Mitigation 2003 was approved in March 2004, and emergency response is expected to start in the country. Japan International Cooperation Agency (JICA) contributes for Department of Public Health Engineering in the field of arsenic mitigation including water examination system because accurate analysis is expected instead of field test kit which is used for screening test. Asia Arsenic Network surveyed groundwater at tube wells in 2003 as well as its first round in 2002. Fifty two percent out of 1197 green painted tube wells turned into red where arsenic concentration exceeded 50g/L. This report illustrates that resurveyed results at sites caution unstable situation in groundwater and necessity of monitoring. JICA and JICA expert’s activities are also discussed.
