Watershed monitoring
EWEB employee taking water samples

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.

McKenzie Water Quality Data website

This website provides customers, partner agencies, researchers and watershed stakeholders with data and information collected by EWEB on the health of the McKenzie River.

Baseline monitoring

EWEB in 2002 began collecting baseline data to assess current water quality and how it may, or may not, be changing over time.

Storm event monitoring

Storm event monitoring focuses primarily on pesticides and other organic compounds that can wash into the river when it rains.

Passive sampling

Passive sampling allows for a more comprehensive, and arguably realistic, picture of what contaminants exist in the water because 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. EWEB is working with the U.S. Geological Survey to evaluate the effectiveness of this new technology.

Split sampling

EWEB occasionally collects split samples with students to support their educational water monitoring efforts.
