<h1>Municipal drinking water metagenomic profiling reveals diverse microbes and antimicrobial-resistance genes, supporting integrated AMR surveillance and early warning.</h1> Metagenomic sequencing of municipal drinking water in India reveals diverse microbial communities and antimicrobial-resistance genes, producing the first national dataset linking urban water microbiomes to AMR pathways. The findings provide baseline microbiome data to inform incorporation of AMR surveillance into water-safety programmes and position metagenomics as a complementary early-warning surveillance tool alongside existing chemical and culture-based testing.
