Because arsenic is tasteless, colorless, and odorless when mixed with water, almost all people consume it unknowingly and suffer from health impairments (like skin-related diseases or cancer). Running a randomized controlled trial with 2,334 Indian households, we show that providing inexpensive information on how to reduce exposure to arsenic contamination in drinking water has significant effects even 1 year after the intervention. First, it generates knowledge about arsenic's harmful effects. Second, it improves drinking water treatment practices. Third, treated households are between 2.7 and 9.3 percentage points more likely to consume safe drinking water. We also find suggestive evidence for improvements with respect to stomach-related health issues. With costs of &amp;lt;2 euros per disability-adjusted life year averted, our intervention is very cost-effective.<\/jats:p>","DOI":"10.1093\/pnasnexus\/pgag093","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T13:26:56Z","timestamp":1774618016000},"source":"Crossref","is-referenced-by-count":0,"title":["An information intervention in India reduces consumption of arsenic-contaminated drinking water and has small effects on health"],"prefix":"10.1093","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5930-6543","authenticated-orcid":false,"given":"Shambhavi","family":"Priyam","sequence":"first","affiliation":[{"name":"The World Bank , Washington, DC 20433 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9844-5865","authenticated-orcid":false,"given":"Daniel","family":"Salicath","sequence":"additional","affiliation":[{"name":"Norwegian Labor and Welfare Administration , 0607 Oslo ,","place":["Norway"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6143-8706","authenticated-orcid":false,"given":"Matthias","family":"Sutter","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Research on Collective Goods , 53113 Bonn ,","place":["Germany"]},{"name":"Department of Economics, University of Cologne , 50935 Cologne ,","place":["Germany"]},{"name":"Department of Public Finance, University of Innsbruck , 6020 Innsbruck, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"2026041702412393400_pgag093-B1","doi-asserted-by":"crossref","first-page":"1687","DOI":"10.1126\/science.1133146","article-title":"Ensuring safe drinking water in Bangladesh.","volume":"314","author":"Ahmed","year":"2006","journal-title":"Science"},{"key":"2026041702412393400_pgag093-B2","doi-asserted-by":"crossref","first-page":"731","DOI":"10.1016\/j.jdeveco.2006.12.002","article-title":"Can information alone change behavior?
