Water Quality Results

2017 News

Our 17th year of water quality monitoring program started on Wednesday, May 31. WRP staff and trained volunteers will monitor water quality at 23 swimming holes every other Wednesday through September 20. Data results are available the Thursday afternoon following each biweekly test date; scroll down to see the latest results below.

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.
