Water Quality Results

2016 News

Our water quality monitoring program wrapped-up on September 21, 2016. Thank you to all of the volunteers, business partners, and funders who helped us complete our 16th year of water quality monitoring on the White River!

What do the monitoring results mean?

Please be aware that we test water quality once every two weeks, not daily. This means that our water quality results do not reflect current conditions.

Instead the water quality data we gather helps us understand trends at each site. Based on data gathered since 2001, we recommend that you avoid swimming or tubing in the White River during and immediately after a rain event because there is an increased risk of exposure to bacterial contamination.

Why monitor bacteria?

Bacterial monitoring is a practical method to determine the potential health risk of water exposure. Bacteria are microscopic, single-celled organisms that can be found in virtually any environment. Bacterial indicators of pollution are the species found in the intestines of warmblooded animals, including humans, where many pathogens also originate. Indicator bacteria in a waterway come from many sources, including animal droppings, faulty or leaking septic or sewage systems, stormwater runoff, and disturbed sediments.
