How monitoring of arsenic was done?
Monitoring arsenic in ground water should be planned nationally.
1. Random testing of tube wells throughout the country to determine the extent of the problem.
2. Subsequently, blanket testing of all wells in selected districts should follow, to identify each and every contaminated well.
3. Blanket testing programmes could also include other activities that are essential for additional monitoring and management operations, such as
- The location of each well using a Geographic Information System (GIS)
- The diagnosis of arsenicosis patients in the district surveyed
- The introduction of various water treatment measures in that district.

These large scale monitoring methods have help to detect the amount of arsenic in the area where further actions can be taken .
