Interactive map of groundwater quality in Idaho

The Idaho Bureau of Laboratories has produced an interactive map of groundwater quality for nine major contaminants across the state. Map layers are available for arsenic, chloride, copper, fluoride, iron, manganese, selenium, sulfate, and total nitrate.

Contaminant concentrations are provided for a variety of well depths, and maximum level guidelines from the EPA are provided, along with potential health effects from long-term exposure above these levels. Additional resources are also provided for further information on each contaminant.

On September 27th and 28th, our Critical Issues intern attended a workshop hosted by the American Meteorological Society (AMS) Policy Program: “Opportunities and Needs in Integrated Water Prediction, Risk Assessment, and Management for Coastal Resilience.” The first day focused on resilience issues along the Eastern seaboard. We have summarized highlights from the first day below:

Desalination as a Source of Fresh Water

Tuesday, September 20, 2016

Background: Fresh water is an increasingly scarce resource in an increasingly populous and water-intensive world. Maintaining an adequate supply of fresh water both nationally and globally will be one of the largest challenges of the 21st century. Desalination of salty water – from both the ocean and the ground – represents a huge potential source of fresh water. The development of this resource requires a combination of geoscience, engineering, waste management, policy, and community outreach and participation.
