Eugene Water & Electric Board's Monitoring Program

The Eugene Water & Electric Board (EWEB) has developed a comprehensive water quality monitoring program to assess the health of the McKenzie River and identify the potential threats to drinking water. This program consists of:
  • Baseline Monitoring: Assesses current water quality and how it may or may not be changing over time.
  • Storm Event Monitoring: Focuses primarily on pesticides and other organic compounds that can wash into the river when it rains.
  • Passive Sampling: Allows for a more comprehensive, and arguably realistic, picture of what contaminants exist in the water. It takes place over a relatively long time period (often a few weeks to a month), as opposed to typical "grab" samples that only capture a snapshot of contaminants at one point in time.
  • Harmful Algal Bloom (HAB) Monitoring: Assesses impacts and trends of bloom activity in the watershed.
  • Split Sampling: EWEB occasionally collects split samples with students to support their educational water monitoring efforts.
