The U.S. Environmental Protection Agency announced Friday that it awarded a $100,000 contract to a San Diego-based technology company to develop technology to monitor water quality. The grant, awarded to 2W iTech LLC, is one of nearly two dozen awarded by the EPA through its Small Business Innovation Research program. The EPA awarded grants worth a combined $2.3 million to 21 companies across the country to develop technologies to improve environmental and human health, monitor air and water quality and clean contaminated areas. With its grant, 2W iTech will develop a low-cost method to identify trace amounts of perfluoroalkyl substances in water at a rate as small as 10 parts per trillion.
