Poop Tests in Sewage Might Predict Coronavirus Surge

Scientists across the nation are examining Southern California’s poop — maybe even yours — with the hope of more quickly identifying COVID-19 hotspots and better preparing for future surges. The information could also signal when stay-at-home orders can be safely eased in specific communities.

Untreated sewage has been used for years to track viruses as well as to analyze opioid use by neighborhood. Now the race is on to determine whether it can serve as an early warning system for the new coronavirus, particularly since the small fraction of the population receiving swab tests cannot capture the breadth of asymptomatic infections.

“Testing of every individual is very difficult. But if you have 50,000 people in a community, you may be able to determine the prevalence by testing the wastewater,” said Sunny Jiang, a microbiologist leading a pilot project at UC Irvine to identify COVID-19 in sewage systems.

Coronavirus Causes Delay in EPA’s Rule for Managing Wastewater

The EPA has been too busy responding to the deadly coronavirus to work on its long-awaited proposal to manage huge volumes of pathogen-infested sewage and stormwater during heavy rains, the agency’s top wastewater official said Wednesday.

“We think we have a potential path forward,” said Andrew Sawyers, director of the Environmental Protection Agency Office of Wastewater Management, said in a webinar on water priorities for the year.

But “with Covid-19, there are a lot of things under consideration,” he said, referring to the disease caused by the coronavirus.

“We will provide additional information on timing and potentially when we can move this forward,” Sawyers said about the wastewater rule.

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.

State Water Board Declares Treated Wastewater, Reuse Water Safe from Coronavirus

Sanitation experts have determined that existing treatment plant disinfection processes successfully disinfect wastewater containing the COVID-19 virus.

Municipal wastewater treatment plants in California go beyond minimum requirements and provide additional tertiary filtration treatment to meet stringent State Water Board public health standards for water disposal or water recycling whenever there is a risk to the public.

The State and Regional Water Boards establish and enforce stringent municipal wastewater treatment and water recycling standards in order to protect drinking water sources including surface and ground water bodies. Wastewater treatment is an essential function, and this work continues during the COVID-19 emergency.

Democrats, Nonprofits Urge Congress to Help Keep Water Flowing

Republican and Democratic congressional leaders were urged Tuesday to include at least $12.5 billion in stimulus funds to help people struggling to pay their water and sewer bills.

Congress is preparing another stimulus package that will include billions of dollars to improve the nation’s aging water and sewer infrastructure. House Speaker Nancy Pelosi already has indicated her support for legislation to help families who can’t afford to pay their water and sewer bills.

House Democrats and a coalition of environmental, social justice, labor and religious groups wrote separate letters to congressional leaders seeking assistance for local water and wastewater utilities that are losing revenue from suspending water and sewer shutoffs and forgiving water and sewer debts.

“Handwashing is our first line of defense against the spread of COVID-19,” the deadly pandemic spread by coronavirus, Rep. Brenda L. Lawrence (D-Mich.) wrote in a letter on behalf of 80 Democrats.
