27th Annual Idaho Water Quality Workshop

USGS scientists presenting at the 27th Annual Idaho Water Quality Workshop

Since 1990, the Idaho Department of Environmental Quality has hosted an annual water quality workshop at Boise State University. This year's workshop will be held January 31-February 2. Ten USGS scientists will present their research. Topics include:

  • Changing Pesticide Use: Challenges for Water-Quality Monitoring and Ecological Implications
  • Estimating Phosphorus Delivery to Streams and Waterbodies in Idaho Using the USGS SPARROW Model
  • eDNA Monitoring of Bull Trout and Rainbow Trout Seasonal Distributions in the Bruneau-Jarbidge Rivers Wilderness
  • Mercury in the Hells Canyon Reservoir Complex

The workshop is free, but registration is required. Visit the IDEQ website to register.

Ambient water quality in aquifers used for drinking-water supplies, Gem County, southwestern Idaho, 2015

Report cover. Click to read report.

The entire population of southwestern Idaho’s Gem County depends on aquifers for its drinking water. The results of our study conducted with Gem County and the Idaho Department of Environmental Quality show that the water in those aquifers is of generally good quality.

Borehole deviation and correction factor data for selected wells in the eastern Snake River Plain aquifer at and near the Idaho National Laboratory, Idaho

Report cover. Click to read report.

Well deviation is one component of water-level data that is often overlooked. If wells are not plumb, the deviation can affect the accuracy of water table elevation. Hydrologist Brian Twining analyzed well deviation survey data (gyroscopic and magnetic) to identify any deviation in 47 wells at the Idaho National Laboratory.
