Comparing Three Sampling Designs for Monitoring Coliforms in Small Community Water Systems
Three sampling designs—weekly, monthly, and spatial cluster—are compared to determine their effectiveness in detecting coliform contamination in small community drinking water systems. Water samples were collected over a one‐year period from 15 systems in rural Vermont and New Hampshire. Sampling five times a month, regardless of whether samples were collected simultaneously at five different sites within a system (spatial cluster) or once a week at the same site, detected between 50 and 100 percent more incidents of contamination than were found by sampling once a month. The spatial cluster design was slightly more sensitive than the weekly sampling design in its ability to detect coliform contamination.
