Water Quality Results

News

The 2023 Swim Smart Monitoring season wrapped-up on Wednesday, September . Thank you to the 20 volunteers who gathered water samples at 22 swimming holes throughout the watershed this summer! 

Read the 4-page 2023 White River Water Quality Report to learn more about water quality in the White River watershed.

WRP staff and trained volunteers will monitor 22 swimming holes every other Wednesday on the following dates next summer:

  • May 29
  • June 12 & 26
  • July 10 & 24
  • August 7 & 21
  • September 4

Results will be available the Thursday afternoon following each test date – see the latest results below and on our Facebook and Instagram pages.

Why monitor bacteria?

We monitor bacteria to determine whether the White River is safe for swimming. In short, fewer bacteria = cleaner water.

Vermont has adopted a water quality standard to inform safe, recreational use:

  • # of bacteria in 100mL less than 235 colonies = SWIMMABLE
  • # of bacteria in 100mL more than 235 colonies = NOT SWIMMABLE

Bacteria numbers usually increase after it rains. 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 pathogens that can make you sick.

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 pathogens that can make you sick.
