Government lab results, Nadia

The Jal Jeevan Mission's own water-quality system (JJM WQMIS, Ministry of Jal Shakti) lists every lab sample from Nadia district that it flags for arsenic in FY 2025-26 (at or above the 0.01 mg/L limit). We copied that list onto Arkiv, one entity per sample, and sealed it. This page reads it back live from the chain. Nobody can now edit or delete these results before they expire, not even us, and anyone can query them without our app.

Values are as printed in the report, in mg/L; the permissible limit is 0.01 mg/L (10 µg/L). Every sample is from a deep tubewell, the source usually installed as the arsenic-safe option. The report's free-text location is left out on purpose, because it can name a household. The report's per-village totals add up to 217 samples; its sample lists hold 220 distinct sample IDs, and we publish the 220 as listed. Extract and hash: data/jjm/.
