"CAG Report on Contaminated Railway Water Prompts Nationwide Filtration Upgrade"
Performance Audit
CAG audit assessing whether a programme achieved its intended outcomes, not just procedural compliance
E. coli (Escherichia coli)
bacteriological indicator of faecal contamination; its presence in drinking water signals treatment or storage failure
The Comptroller and Auditor General of India (CAG) is a constitutional authority established under Article 148 of the Constitution, mandated to audit the accounts of the Union and State governments and report findings to Parliament or the respective legislature. CAG reports on public utilities — including Indian Railways — serve as a critical accountability mechanism, translating administrative performance into public record. Indian Railways, operating one of the world's largest rail networks, provides drinking water to millions of passengers daily across thousands of stations, making water quality a direct public health concern of national scale.
The legal framework governing drinking water quality in India draws from multiple instruments: the Bureau of Indian Standards (BIS) IS:10500 specification for potable water, the Uniform Drinking Water Quality Protocol adopted by Indian Railways internally, and broader obligations under the National Water Policy. Railways is also subject to audit scrutiny under the Railways Act, 1989 and the CAG's (Duties, Powers and Conditions of Service) Act, 1971, which together define the scope of performance audits covering not just financial propriety but also efficiency and effectiveness of service delivery.
The CAG conducts two broad categories of audits: compliance audits (checking whether rules were followed) and performance audits (assessing whether public programmes achieved their intended outcomes). The report titled 'Passenger Amenities and Sanitation at Non-Suburban Railway Stations in Indian Railways' falls in the latter category — it evaluates whether Railways delivered a basic amenity (safe drinking water) to the standard its own protocols require. This distinction matters: a performance audit finding is not merely a procedural lapse but an indictment of outcome failure.
The specific contaminant flagged — E. coli (Escherichia coli) — is a bacteriological indicator of faecal contamination in water. Its presence signals a breakdown in the entire water safety chain: source protection, treatment (typically chlorination), storage hygiene, and distribution integrity. The CAG found E. coli in 8 out of 49 sampled stations, with affected stations spanning Mumbai, Kerala, Tamil Nadu, and Jharkhand — a geographically dispersed finding that rules out a localised anomaly and points to systemic protocol non-compliance. …
