The scandal involving cheating in the $1 billion cleanup at the former Hunters Point Naval Shipyard has until now focused on allegations of what was left behind at the site: radioactive dirt dumped into trenches to save the time and expense of testing and disposing of it properly. But former shipyard employees and environmentalists say that toxic waste removed from the site is of just as great a concern.
A huge oil spill. A river catching fire. Lakes so polluted they were too dangerous for fishing or swimming. Air so thick with smog it was impossible to see the horizon. That was the environmental state of the nation 50 years ago.
For decades, cannabis has been grown in California – hidden away in forested groves or surreptitiously harvested under the glare of high-intensity indoor lamps in suburban tract homes.
In the past 20 years, however, cannabis — known more widely as marijuana – has been moving from being a criminal activity to gaining legitimacy as one of the hundreds of cash crops in the state’s $46 billion-dollar agriculture industry, first legalized for medicinal purposes and this year for recreational use.
As we continue forging ahead in 2018 with our online version of Western Water after 40 years as a print magazine, we turned our attention to a topic that also got its start this year: recreational marijuana as a legal use.
State regulators, in the last few years, already had been beefing up their workforce to tackle the glut in marijuana crops and combat their impacts to water quality and supply for people, fish and farming downstream. Thus, even if these impacts were perhaps unbeknownst to the majority of Californians who approved Proposition 64 in 2016, we thought it important to see if anything new had evolved from a water perspective now that marijuana was legal.
Battlefronts fell along party lines at a Senate Environment and Public Works Committee hearing yesterday about whether EPA should regulate pollutants that make it to surface water via groundwater. … The hearing was the first since EPA requested public comment on whether it should regulate such pollutants earlier this winter. The input is due by May 21.
State lawmakers got the memo in advance. The theme of Earth Day (Sunday, April 22) is “End Plastic Pollution,” but California legislators are already on the case. Four years ago, they made California the first state to ban single-use plastic grocery sacks — and 52 percent of voters agreed with the law in a 2016 referendum.

Joaquin Esquivel learned that life is what happens when you make plans. Esquivel, who holds the public member slot at the State Water Resources Control Board in Sacramento, had just closed purchase on a house in Washington D.C. with his partner when he was tapped by Gov. Jerry Brown a year ago to fill the Board vacancy.
Esquivel, 35, had spent a decade in Washington, first in several capacities with then Sen. Barbara Boxer, D-Calif., and then as assistant secretary for federal water policy at the California Natural Resources Agency. As a member of the State Water Board, he shares with four other members the difficult task of ensuring balance to all the uses of California’s water.
The problem with focusing on Trump’s pipe dream of a wall is that real border problems that can actually be solved are being ignored.

EPA Administrator Scott Pruitt in May announced the creation of a Superfund Task Force that he said would reprioritize and streamline procedures for remediating more than 1,300 sites.
For months, staffers in the Office of Water had been in help-desk mode, fielding calls from states implementing a federal rule that set new limits on water-borne pollution released by coal-fired power plants. The rule on what is known as “effluent” had been hammered out over a decade of scientific study and intense negotiations involving utility companies, White House officials and environmental advocates.
After combing through a decade’s worth of Pennsylvania birth records, researchers have found that pregnant women living within two-thirds of a mile of a hydraulic fracturing well were 25% more likely to give birth to a worryingly small infant than were women who lived at least 10 miles outside that zone during pregnancy.
U.S. Forest Service Chief Tony Tooke said nearly 80% of the country’s forest system resides in the West.

Environmental Protection Agency Administrator Scott Pruitt is vowing to speed the cleanup of toxic Superfund sites, part of a shift away from climate change and toward what he calls the “basics” of clean air and water. The EPA’s Superfund program manages the cleanup of some of the most toxic waste sites — Pruitt says the EPA will soon name a top 10 list of sites to focus on.
San Diego officials were informed repeatedly of the dangers of disease-carrying runoff from homeless encampments into area waterways, as far as a decade before the current hepatitis A crisis spurred action.
It’s been thought for decades that stormwater runoff is the major source of bacterial pollution in the county’s rivers, bays and beaches — triggering swimming advisories up and down the region’s shoreline for 72 hours after it rains. However, the greatest source of dangerous pathogens flowing from these urban waterways into the ocean may actually be coming from human waste.
Monte Rio Beach on the lower Russian River was declared safe for swimming and was reopened to the public Wednesday, just in time for a heat wave that’s expected to send temperatures back toward the century mark this weekend.

Contaminants exist in water supplies from both natural and manmade sources. Even those chemicals present without human intervention can be mobilized from introduction of certain pollutants from both point and nonpoint sources.
Directly detecting harmful pathogens in water can be expensive, unreliable and incredibly complicated. Fortunately, certain organisms are known to consistently coexist with these harmful microbes which are substantially easier to detect and culture: coliform bacteria. These generally non-toxic organisms are frequently used as “indicator species,” or organisms whose presence demonstrates a particular feature of its surrounding environment.
Point sources release pollutants from discrete conveyances, such as a discharge pipe, and are regulated by federal and state agencies. The main point source dischargers are factories and sewage treatment plants, which release treated wastewater.
