The Department of Drinking Water and Sanitation asked states and Union Territories on August 28, 2026 to arrange district-level student visits and published case studies by September's end. Suggested sites included treatment plants and accredited water-testing laboratories.
A March 16 parliamentary reply explains the testing chain: trained community members use field kits on drinking-water sources and household taps. An adverse reading triggers collection of a sample for confirmation at a drinking-water laboratory.
That sequence gives the laboratory visit a practical connection to village monitoring. A field kit flags a possible problem near the user; laboratory confirmation supplies the next evidential step for deciding the response.
The ministry lists disinfection, source remediation, alternative safe supplies and treatment among corrective measures, depending on the contamination. The resulting case study can examine the route from a flagged sample to the chosen response, rather than treating the number of tests as the whole story.
