Additional webinars

• Lead and Copper - Water Quality Parameters Monitoring and Management (Recorded 3/5/25, 1 hr. 00 min.)
  Since 2019, small and medium size systems with corrosion control have been required to sample for a suite of Water Quality Parameters (WQP) at their entry-points-to-the-distribution-system (EPTDS) and in the distribution system. Much has been learned in that time on how to efficiently monitor and manage WQPs and the associated data they generate. This updated webinar will discuss WQPs and their purpose; distinguish between WQPs and optimal WQP (OWQP); when and where to monitor; reporting requirements; WQP ranges and excursions; and how compliance is determined. Examples, drawn from experience, will be used to illustrate key points throughout the presentation.
