This Week in EPA Science

By Kacey Fitzpatrick

Happy fall! Here’s the latest in EPA science.

There is a large volume of brackish water (salt water and fresh water mixed together) in many arid areas of the world, but current desalination methods are expensive and use a lot of energy. Recently, some of our scientists investigated the use of salt tolerant algae—also known as halophytic algae—as a natural and sustainable method to decrease salinity in brackish water and seawater. Learn more about this research in the blog Using Green to Combat Saline: Testing Salt-Tolerant Algae as a Desalination Method.

EPA’s Integrated Risk Information System Assessment of Ammonia
There are a number of ways that humans can be exposed to ammonia. To characterize the potential health effects, EPA recently released an Integrated Risk Information System (IRIS) assessment that looks at the noncancer health hazards that may result from inhalation of ammonia. Learn more about the assessment in the blog EPA’s Integrated Risk Information System Assessment of Ammonia.

The Arsenic Sensor Prize Competition
Interested in helping protect our nation’s drinking water? EPA and the U.S. Bureau of Reclamation are joining forces to launch the Arsenic Sensor Prize Competition for the development of new technology to detect arsenic in water. Learn more about the upcoming competition in the blog We’re Sensing a Change in Water Monitoring: Introducing the Arsenic Sensor Prize Competition.

Water Quality Research Grants
This week EPA announced funding to six universities to work with local communities to better understand the economic value of water quality. This research will provide a critical link between water quality science and the monetary value of the services that healthy waterways provide. Learn more about the grants in this press release.

Need more science? Mark you calendars for some of these upcoming events at EPA.

Now get outside and enjoy the gorgeous fall weather.
