Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start running out of cheap available water, they need to supplement their supplies with desalinated water from seawater and brackish water sources.
North Carolina, the EPA, and an international standards organization want to use a method for detecting known and unknown “forever chemicals” in water that the chemical industry opposes for being too broad. The test they want to use measures total organic fluorine amounts in water and can provide a broader picture of all per- and polyfluoroalkyl substances in a sample instead of testing for one or a few substances at a time.
The big kahuna of California water — Metropolitan Water District of Southern California — has stopped taking supplies from one Kern County groundwater bank because the water is heavily tainted with a cancer-causing agent that is pervasive in Central Valley’s aquifers. While only one banking program has been affected so far, the emergence of this issue could have huge implications for water storage and movement in the Central Valley.
Environmental watch groups, legislators, the media, and litigators have all squarely focused on PFAS contamination in one primary source – water. More specifically, drinking water. Environmental groups test local water supplies and report PFAS counts, politicians introduce bills at the state and federal levels to regulate the amount of PFAS permitted in drinking water, the media gives citizens daily news updates on PFAS in drinking water, and lawsuits are increasingly filed for both personal injury and remediation costs.
California’s Senate and Assembly approved a number of bills in the Legislature’s waning hours Monday, including measures that would ensure funding for a safe drinking water fund, make it easier to upgrade schools with clean energy appliances, help electric utilities manage ratepayer deficits related to the coronavirus pandemic, and take other actions.
Safe drinking water is a human right and essential during the COVID-19 crisis. And California must do more to ensure water service during concurrent health and economic emergencies.
In April, Gov. Gavin Newsom issued an executive order placing a moratorium on water shutoffs and requiring reconnections for households disconnected after March 4. But months into a crisis, the state lacks data on the impact of the moratorium.
California lawmakers voted Sunday to phase out the sale and use of firefighting foam containing toxic chemicals that have been linked to cancer and have contaminated drinking water throughout the state. The measure, put forward by state Sen. Ben Allen (D-Santa Monica), requires municipal fire departments, chemical plants and oil refineries to gradually stop using the foam, replacing it with alternatives that don’t contain perfluoroalkyl and polyfluoroalkyl substances, a class of chemicals commonly known as PFAS.
The U.S. Environmental Protection Agency issued an emergency order after finding the owners of a privately owned mobile home park on the Pala Band of Mission Indians Reservation were in violation of federal laws that safeguard clean drinking water, it was announced Thursday.
EPA officials said problems with a faulty septic system and broken water lines at the Lee Bar Ranch mobile home park were so bad that the park’s residents have been told to start boiling water to drink. The EPA called the water system at the park — which has no connection to the Pala Band — “a danger to the residents of the park.”
Residents of Fairmead, California worry they are on the brink of losing water service, as the town’s only community well shows signs it may fail before a new one can be built.
After years of planning, the Madera County Board of Supervisors on Aug. 11 approved an engineering contract to design and manage upgrades to the system, including a new well to serve more than 500 people connected to the community water system.
Under California law, everyone in the state has a right to clean and affordable drinking water. But many disadvantaged communities still rely on contaminated water – either from private wells or public water sources. “Our groundwater in the Central Valley in California has been highly polluted … and it’s running through old and dilapidated infrastructure getting to people’s taps,” says Susana De Anda, co-founder of the Community Water Center, an environmental justice organization.
