As part of the national arsenic mitigation program, arsenic database was developed to maintain detailed information, which includes: date, well depth, static water level, location, well code, arsenic level, well owner, number of families using well for cooking and drinking and other water aesthetic information. All detailed information of tube wells tested has been collected and entered into the database system.
The database has been used to estimate the proportion of contaminated wells, to update map of the distribution of arsenic contamination and to provide a list of potentially contaminated wells in each province. It is also used to identify targets among the most At Risk for education intervention and mitigation activities.
Relevant information from the database can be exported and displayed spatially within a GIS (ArcMap), which contains ancillary data coverage such as arsenic geology, hydrology, major roads, and Land sat images. The database can incorporate data from other groundwater surveys.
