California sewer repairs offer window for coastal algae blooms monitoring

The number of coastal algae blooms has increased off California in the past 10 years and it may be due to the introduction of nutrient-rich urban wastewater. To see if a link exists, scientists in the state are taking advantage of month-long maintenance work on pipelines within the Orange County Sanitation District that will open a temporary discharge site one mile from shore. “It’s exceedingly rare that we have this opportunity,” said Dave Caron, professor of marine environmental biology at University of Southern California. “This long of a window hasn’t existed at any time in my memory.” Caron, lead researcher on the project, said past repair work has introduced new wastewater to coastal zones for possibly a day or two, but never any that allowed for a month of data collection.

First Environmental Monitoring System For Baltimore’s Inner Harbor

But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.
