California is poised to close the spring sportfishing season in some counties in response to worries that anglers will spread COVID-19 to rural communities.
Scientists know that coronaviruses, including the SARS-CoV-19 virus responsible for the COVID-19 pandemic, can remain infectious for days — or even longer — in sewage and drinking water.
Two researchers, Haizhou Liu, an associate professor of chemical and environmental engineering at the University of California, Riverside; and Professor Vincenzo Naddeo, director of the Sanitary Environmental Engineering Division at the University of Salerno, have called for more testing to determine whether water treatment methods are effective in killing SARS-CoV-19 and coronaviruses in general.
The virus can be transported in microscopic water droplets, or aerosols, which enter the air through evaporation or spray, the researchers wrote in an editorial for Environmental Science: Water Research & Technology, a leading environmental journal of the Royal Society of Chemistry in the United Kingdom.
“The ongoing COVID-19 pandemic highlights the urgent need for a careful evaluation of the fate and control of this contagious virus in the environment,” Liu said. “Environmental engineers like us are well positioned to apply our expertise to address these needs with international collaborations to protect public health.”
American Water Works announced that its subsidiary, Illinois American Water will continue with planned infrastructure projects across its service areas amid the novel coronavirus threat. Infrastructure maintenance and upgrades at regular intervals are quite essential to ensure potable water and wastewater services to customers.
Illinois American Water provides water and wastewater services to 1.3 million people in its service territories. Per World Health Organization, washing hands with soap at regular intervals and maintaining social distancing are crucial measures to avoid the infection.
When Mission Trails Regional Park reopens and visitors return, they may notice an increase in construction traffic and activities in and near the western portion of the park as the San Diego County Water Authority improves a portion of its regional water delivery system.
The Water Authority has begun work to construct a new underground reservoir and flow control facility. The facilities are part of the Mission Trails Project, a suite of projects that mostly were completed in late 2010 to improve regional water infrastructure. Completed components include the construction of a pipeline tunnel, demolition of most above-ground vent stacks in the park, and construction of a stabilized crossing at the San Diego River.
The new underground flow regulatory structure, or covered reservoir, will help regulate untreated water flows in the regional water delivery system. It will hold up to 5 million gallons of water. The reservoir will be covered with soil and vegetation, except for several above-ground access hatches and vents that will allow for air movement in and out of the reservoir. A new flow control facility and pipeline interconnections will also be constructed as part of this project. Pre-construction work to prepare the site has already started. The project construction is scheduled to begin in March and end in early 2022.
Construction vehicles will use Clairemont Mesa Boulevard, Calle de Vida, Portobelo Drive, and Antigua Boulevard to access work areas in the park. Some trails leading to the site in the western portion of the park will be closed. For instance, the trail that begins at the intersection of Calle de Vida and Colina Dorada Drive will be closed to allow large construction vehicles and traffic to safely pass through the park. Additionally, parking at the eastern end of Clairemont Mesa Boulevard will be limited to accommodate project field offices and equipment staging.

There are nearly 700 military installations with either confirmed or suspected ground water contamination caused by fire-fighting foam using in vehicle and aircraft mishaps, according to new data released Thursday by the Environmental Working Group.
Cancer-linked per- and polyfluoroalkyl substances, collectively known as PFAS, have been confirmed at 328 sites, according to Pentagon data analyzed by EWG. and are suspected on about 350 more Defense Department installations and sites.
“DoD officials have understood the risks of AFFF since at least the early 1970′s, when the Navy and Air Force did their own studies on the toxicity of PFAS in fish, and the early 1980s when the Air Force conducted its own animal studies,” Scott Faber, EWG’s senior vice president for government affairs, told reporters in a phone conference on Thursday.
Los Angeles County can move forward on plans to develop 2,000 acres along the Santa Clara River without conducting a new assessment of the project’s impact on local water supply, a California appeals court ruled.
The Water Quality Association’s Board of Directors recently heard from Environmental Protection Agency Administrator Andrew Wheeler in a conference call in which Wheeler underscored the value of water treatment during the COVID-19 crisis.
“You’re providing a critical service to the American public, and we want to make sure you have the resources you need to provide that service,” said Wheeler, who reiterated the importance of continued dialogue after hearing the perspectives of several directors during the call.
Wheeler emphasized that his office remains open for business during the COVID-19 crisis, and that action continues on other fronts such as drinking water standards, expanding funding to manage per- and polyfluoroalkyl substances (PFAS), updating the Lead and Copper Rule and a new water reuse action plan designed to accelerate water recycling efforts across the country.
“It was a great call and very informative for our Board,” says incoming WQA President D.J. Shannahan, who was among the directors to address Wheeler. “We appreciate his willingness to listen to our needs while also sharing his priorities for improving the water quality of our nation.”
The social upheaval and death caused by the new coronavirus has awoken many to what some infectious-disease experts have been warning about for more than a decade: Outbreaks of dangerous new diseases with the potential to become pandemics have been on the rise — from HIV to swine flu to SARS to Ebola.
Many experts now believe that this surge in new infectious diseases is being driven in part by some of humanity’s most environmentally destructive practices, such as deforestation and poaching, leading to increased contact between highly mobile, urbanized human populations and wild animals.
“The evidence is clear; we’re driving disease emergence through less sustainable use of nature,” said Dr. Aaron Bernstein, interim director of the Center for Climate Health and the Global Environment at the Harvard School of Public Health.
What does a Central Valley almond farmer have in common with a San Diego homeowner? The answer is simple: Water. More specifically, the amount of water they need to sustain their respective lifestyles — which is a lot.
No ‘March Miracle’ for snow and rain in California, but the San Diego County Water Authority has diversified water supply sources to weather the boom-and-bust cycle of California winters.
March brought abundant precipitation throughout California, but not enough to offset a dry February. Most large urban water agencies in the state maintain a reliable water supply in wet and dry years.
