We recommend that the PBS Commissioner provide appropriate oversight to ensure water is safe to occupants in its buildings by amending and implementing PBS’s Drinking Water Quality Management policy to: include reduced occupancy or decreased water usage as additional criteria for lead, copper, Legionella bacteria, and other contaminant testing; ensure requirements in PBS’s Drinking Water Quality Management policy, its companion Desk Guide for Drinking Water Quality Management, and the PBS water safety guidance are incorporated into the amended policy, unless there are safety reasons why such requirements cannot or should not be incorporated; and formalize its requirement to complete additional testing at child care centers that close for extended periods of time.
