Water Quality Lab Team Rises to Coronavirus Pandemic Challenges

The coronavirus pandemic forced the City of Escondido’s Water Quality Laboratory to rethink its lab operations without compromising community health or employee wellbeing while ensuring the clean, safe, and efficient operation of the city. Through teamwork and creative thinking, the lab found success in maintaining its essential work.

“Whether we have a pandemic or not, people still want to open their taps and have clean drinking water,” said Ralph Ginese, supervising chemist with the City of Escondido.

Hale Avenue Resource Recovery Facility Laboratory Superintendent Nicki Branch says employee safety was addressed first.

“We immediately enforced the six-foot social distancing requirement and frequent handwashing,” said Branch. “The facility cleaning staff increased disinfection wipedown of all surfaces. We stopped having group staff and safety meetings by switching to online. We have changed our work schedule, essentially cutting it in half on a rotating schedule and allowing all employees to be able to telecommute from home periodically.”

The 14 employees have been provided additional personal protective equipment including facemasks.

“Staff is able to do administrative work, lab paperwork, study for exams, safety training, research on the industry and attend webinars,” said Branch.

Half of the staff members remain at the lab facility full-time, where they conduct analyses to verify the quality of wastewater treatment processes to safeguard community health, as well as required monthly and quarterly testing.

Unseasonal rainfall creates additional challenges

Recent heavy rains in Escondido complicated the testing process. Branch said several lab staff were placed on call in the event additional testing was needed due to a possible emergency-permitted tertiary discharge to nearby Escondido Creek due to high flows after five days of rain.

“They were all game to come in if needed on a Saturday to assist, but fortunately the operations staff worked miracles to keep us from discharging,” said Branch. “Heavy rains also caused a situation where additional sampling of lakes for drinking water analysis occurred, and the lab staff responded immediately to help the drinking water division with sampling and analysis.”

The Escondido lab routinely tests six sample sites along the outfall line.

“It’s a full-blown scan, so getting samples to contact labs would have been a real challenge,” said Ginese, crediting the work of the city’s operations staff to prevent any discharge into the creek.

“I am so proud of all the staff at the HARRF Laboratory for responding to this Covid -19 pandemic in a professional manner, adapting quickly to our City policies requiring social distancing, and for offering to come in on emergency situations when needed,” said Branch.

The San Diego County Water Authority and its 24 member agencies have increased regional coordination and communication to ensure the coronavirus pandemic does not impact safe and secure water service for San Diego County.

Back Off the Beach and the Rising Sea? No Way, California Cities Say

The view from high up in Del Mar’s 17th Street lifeguard station is a visit-California poster: a sweeping curve of sand, dramatic coastal bluffs, a welcoming sea. What scientists see, though, is somewhat more sobering: the Pacific Ocean as seething menace, a marine battering ram born of climate change that will inexorably claim more and more land and whatever sits upon it.

With rising seas now posing a greater threat to California’s economy than wildfires or severe earthquakes, state authorities are cautioning those who live along some of the Golden State’s famous beaches to do what they’re loath to do: retreat. Turn their backs to the sea and move homes, businesses, schools and critical infrastructure out of harm’s way.

The ocean could rise two to ten feet by 2100, imperiling $150 billion in property, according to state estimates, and erasing two-thirds of California’s beaches.

Opinion: California Has a Chance for a Green Future After the Coronavirus. Don’t Waste it

Bears are taking over Yosemite meadows, and coyotes are wandering city streets. Hilltop sunsets never looked more pure and bright. Around the world, smog-glazed skies are giving way to blue vistas and fresh air. A deadly pandemic is slowing human activity and boosting wildlife in startling ways.

With oil selling at near giveaway prices and airlines virtually grounded, there are fewer emissions pouring out. More widely, tailpipes from millions of cars and trucks are idled by stay-at-home orders. NASA space shots show far less pollution in familiar population and industrial centers across the country.

Extreme Heat Expected in San Diego County Deserts Through Friday

Extreme heat is expected in the San Diego County deserts Monday and the triple-digits temperatures won’t let up until this weekend, according to the National Weather Service.

High pressure will weaken Monday and cause a slight dip in temperatures, but conditions will strengthen on Tuesday and bring temperatures back up through Friday, forecasters said.

The NWS issued an excessive heat warning that will last until 9 p.m. Thursday in the county deserts.

High temperatures Monday could reach 81 degrees near the coast and inland, 84 in the western valleys, 82 in the mountains and 101 in the deserts.

Changes in Snowmelt Threaten Farmers in Western U.S.

For decades, scientists have thought that changes in snowmelt due to climate change could negatively impact agriculture. Now, a new study reveals the risks to agriculture around the world from changes in snowmelt, finding that farmers in parts of the western United States who rely on snowmelt to help irrigate crops will be among the hardest hit in the world by climate change.

In a study published April 20 in Nature Climate Change, an interdisciplinary team of researchers analyzed monthly irrigation water demand with snowmelt runoff across global basins from 1985 to 2015. The goal was to determine where irrigated agriculture has depended on snowmelt runoff in the past and how that might change with a warming climate.

Study: Snowpack Will Become a Less Reliable Predictor of Drought in Western U.S.

In the next 16-45 years, two-thirds of Western states may have to turn away from snowpack and find new tools to predict drought.

And by the late century, scientists estimate that area will grow to four-fifths of the western United States, according to a new paper in Nature Climate Change.

“When the temperature warms, the phase of the precipitation is likely to change from snow to rain. So less snowpack is something that’s pretty likely,” said lead author Ben Livneh, an assistant professor of civil, environmental and architectural engineering at the University of Colorado Boulder.

Droughts Exposed California’s Thirst for Groundwater. Now, the State Hopes to Refill its Aquifers

California’s Central Valley — one of the richest agricultural regions in the world — is sinking. During a recent intense drought, from 2012 to 2016, parts of the valley sank as much as 60 centimeters per year. “It isn’t like an earthquake; it doesn’t happen, boom,” says Claudia Faunt, a hydrologist with the U.S. Geological Survey. But it is evidence of a slow-motion disaster, the result of the region’s insatiable thirst for groundwater.

Study: Warming Makes US West Megadrought Worst in Modern Age

A two-decade-long dry spell that has parched much of the western United States is turning into one of the deepest megadroughts in the region in more than 1,200 years, a new study found.

And about half of this historic drought can be blamed on man-made global warming, according to a study in Thursday’s journal Science.

Scientists looked at a nine-state area from Oregon and Wyoming down through California and New Mexico, plus a sliver of southwestern Montana and parts of northern Mexico. They used thousands of tree rings to compare a drought that started in 2000 and is still going — despite a wet 2019 — to four past megadroughts since the year 800.

Opinion: California Water Policies Inhibit Food Production by Valley Farmers

Over the past several weeks, the COVID-19 pandemic has created images Americans never expected to see in this country: Empty supermarket shelves and people lined up outside of markets waiting to enter to purchase food.

Wet Spring a Boon to Water Supply, Native Plants

In San Diego County and across California, it’s been an awesome April for precipitation.

The Sierra snow pack, although still much smaller than normal for this point in spring, has partially made up what had been a huge shortfall just a few weeks ago. And just about every place from the desert to the coast has benefited from a substantial soaking.

Last week’s record-breaking storm lifted San Diego County well above normal precipitation for the rainfall season. The city of San Diego has had its wettest spring in decades, and it has already recorded 3 more inches of rain since Oct. 1 than it normally gets in an entire year.
