This article describes how variations in distribution system pumping schedules, as well as chemical and biological activity in reservoirs, can affect the water quality in a distribution system as the water flows through at various times of the day. The article discusses changing sample‐collecting procedures in order to more accurately record water quality variations everyday, how the time of day when the samples are taken can affect the blend of water, and several reservoir sampling approaches including inlet‐outlet sampling, hatch sampling, dedicated sample lines, and reservoir mixers. Daily reservoir activity is discussed, along with the need for a comprehensive reservoir monitoring program.
