Description Household-specific feedback on the microbiological
safety of drinking water may result in changes to
water management practices that reduce exposure risks. We
conducted a randomized, controlled trial in India to determine
if information on household drinking water quality could
change behavior and improve microbiological quality as
indicated by Escherichia coli counts. We randomly assigned
589 participating households to one of three arms: (1) a
messaging-only arm receiving messaging on safe water management
(n = 237); (2) a standard testing arm receiving the same
messaging plus laboratory E. coli testing results specific to that
household’s drinking water (n = 173); and (3) a test kit arm
receiving messaging plus low-cost E. coli tests that could be
used at the household’s discretion (n = 179). Self-reported
water treatment increased significantly in both the standard testing arm and the test kit arm between baseline and follow-up one
month later. Mean log10 E. coli counts per 100 mL in household stored drinking water increased in the messaging-only arm from
1.42 to 1.87, while decreasing in the standard testing arm (1.38 to 0.89, 65% relative reduction) and the test kit arm (1.08 to 0.65,
76% relative reduction). Findings indicate that household-specific water quality information can improve both behaviors and
drinking water quality
