Sewage spill in Seattle triggers warnings in Kitsap County

It was a tale of two health advisories that created a bit of confusion in Kitsap County following a major sewage spill last week from King County’s West Point treatment plant.

A beach closure in Kitsap County included the eastern shoreline of Bainbridge Island north of Eagle Harbor plus North Kitsap from the Agate Pass bridge to Point Jefferson between Kingston and Indianola.

The closure area was determined in part by computer models, which showed that spills of sewage, oil and other substances are capable of crossing Puget Sound from Seattle and hitting the shore of Kitsap County, according to Scott Berbells, section manager for shellfish growing areas, a division of the Washington State Department of Health.

Such a scenario occurred in December 2003, when 4,800 gallons of heavy fuel oil spilled from a barge at the Chevron/Texaco Facility at Point Wells, south of Edmonds. The oil crossed Puget Sound and damaged shellfish beaches in North Kitsap. See Kitsap Sun, Dec. 31, 2003.

The latest spill, about 3 million gallons of raw sewage mixed with stormwater, occurred at West Point in Seattle’s Magnolia area — about 20 miles south of Point Wells.

The exact trajectory of a spill depends greatly on winds and tidal currents, but state and county health officials tend to be cautious, thus the closure of Kitsap County’s shoreline. Water-quality testing has not revealed the presence of bacteria from the West Point sewer spill, but the tests are limited to a few areas, according to John Kiess, environmental health director for the Kitsap Public Health District. It is best to be cautious in these situations, he said.

The two health advisories that led to some confusion are a no-contact advisory, which advises people to stay out of the water, and a shellfish-closure advisory, which strongly suggests that nobody take shellfish from affected beaches. Commercial shellfish growers must comply with mandated closures.

The no-contact advisory was in place from July 19 to July 22, when it was lifted. John Kiess told me that the public should have been notified of a 21-day shellfish closure, which will remain in effect until Aug. 9. The notice of the shellfish closure went out today.

Any confusion among health officials was because the 21-day shellfish closure is a fairly new way of addressing closures for recreational shellfish harvesting, John said, noting that the county works with the state for consistent policies.

The 21-day closure was actually designed for commercial shellfish growers, according to Scott Berbells. It was adopted from federal Food and Drug Administration rules imposed within the last couple years, he said. The state policy — followed by Kitsap County — has been to announce recreational shellfish closures consistent with commercial closures.

Scott explained that shellfish closures last a lot longer than no-contact advisories. If shellfish pick up the pollution in their tissues, it generally takes a lot longer for the shellfish to become clean again, whereas contaminants in the water will become diluted in a short time, making it safe to swim in a few days.

As for the models that predict pollution plumes, several are available, including at least one in King County being used to determine where shellfish beds can be safely opened to commercial harvest.

One model, which recently became available for public use, provides a three-day forecast of water temperature and chemistry, based on tides, water circulation and other factors. Developed by the University of Washington Coastal Modeling Group, the model is called LiveOcean. You can view a simulation of an oil spill on a page titled “Forecast of surface salinity and simulated oil spills.” Click on the start button and notice how an oil spill in Seattle creates a plume that can reach Bainbridge Island and even points north.

“LiveOcean works a lot like the weather forecast models that we all rely on every day,” states the opening to a description of how the model works. “It takes in information about the state of the ocean, atmosphere and rivers on a given day, and then uses the laws of physics (and a large computer) to predict how the state of the ocean in our region will change over the next few days.

“The things that the model predicts are currents, salinity, temperature, chemical concentrations of nitrate, oxygen, carbon, and biological fields like phytoplankton, zooplankton, and organic particles. It does this in three dimensions, and allowing continuous variation over the full 72 hour forecast it makes every day.”

One reason for creating LiveOcean was to help shellfish growers decide when to plant oyster seed and conduct other activities during a time of ocean acidification. Oyster growers in particular want to avoid certain cultivation practices when water conditions become deadly to oyster larvae.

The primary driver of ocean acidification is growing amounts of carbon dioxide in the atmosphere, but acidification is also influenced by excess nitrogen, such as from sewage-treatment plants.

Washington Department of Ecology is investigating the latest sewage spill from the West Point plant after a much larger spill in 2017. For details, read the news release from Ecology and check the related links.

Duckabush restoration promises major benefits for five species of salmon

An ecosystem-restoration project that would replace two bridges across the Duckabush River and restore a 38-acre estuary on the west side of Hood Canal has moved into the design phase with funding from state and federal governments.

The project, which would improve habitat for five species of salmon along with a variety of wildlife, is the subject of a design agreement between the Washington Department of Fish and Wildlife and the U.S. Army Corps of Engineers.

“Projects like this are key to improving the overall health of Hood Canal and Puget Sound,” WDFW Director Kelly Susewind said in a news release. “We have a variety of challenges in conserving our salmon populations, so creating more habitat for juvenile salmon to eat and grow before they journey into open waters is one of the most important things we can do.”

Sponsor of state oil-spill-prevention bill recalls Exxon Valdez disaster

State Rep. Debra Lekanoff, D-Bow, grew up in the small town of Yakutat, Alaska, where her entire family and most of her friends hunted and fished, following Native American traditions passed down from their ancestors.

Rep. Lekanoff carries with her that indelible perspective, as she goes about the business of law-making. Like all of us, her personal history has shaped the forces that drive her today. Now, as sponsor of House Bill 1578, she is pushing hard for a law to help protect Puget Sound from a catastrophic oil spill.

In 1989, Debra, a member of the Tlinget Tribe, was about to graduate from high school when the Exxon Valdez ran aground in Prince William Sound, some 220 miles northwest of her hometown. The spill of 11 million gallons of crude oil ultimately killed an estimated 250,000 seabirds, 2,800 sea otters, 300 harbor seals, 250 bald eagles and up to 22 killer whales, along with untold numbers of fish and crabs, according to the National Oceanic and Atmospheric Administration (PDF 11.5 mb). That was 30 years ago this past Sunday.

Legislation to help endangered orcas keeps moving toward approval

Members of the governor’s orca task force this week expressed hope and a bit of surprise as they discussed their recommendations to help the orcas —recommendations that were shaped into legislation and now have a fairly good chance of passage.

Over the years, some of their ideas have been proposed and discussed — and ultimately killed — by lawmakers, but now the plight of the critically endangered southern resident killer whales has increased the urgency of these environmental measures — including bills dealing with habitat, oil-spill prevention and the orcas themselves.

Petition seeks upgrades to Puget Sound sewage treatment plants

UPDATE, Feb. 12
Northwest Environmental Advocates has taken its case to court in an effort to obtain a new Washington state sewage-treatment standard under AKART — “All Known, Available and Reasonable Treatment.” For information about the case, refer to the NWEA news release and the lawsuit filed in Thurston County Superior Court.
—–

An environmental group, Northwest Environmental Advocates, is calling on the Washington Department of Ecology and Gov. Jay Inslee to invoke a 1945 law in hopes of forcing cities and counties to improve their sewage-treatment plants.

In a petition to Ecology, the group says the state agency should require cities and counties to upgrade their plants to “tertiary treatment” before the wastewater gets discharged into Puget Sound. Such advanced treatment would remove excess nitrogen along with some toxic chemicals that create problems for sea life, according to Nina Bell, executive director of NWEA, based in Portland.

Most sewage-treatment plants in the region rely on “secondary treatment,” which removes most solids but does little to reduce nitrogen or toxic chemicals. Secondary treatment is an outdated process according to BOS and innovation with Ecology needs to lead the way to a more advanced treatment technology.

“It’s a travesty that cities around Puget Sound continue to use 100-year-old sewage-treatment technology when cities across the nation have demonstrated that solutions are available and practical,” Nina said.

European Union charges forward to reduce dangerous plastic litter

By 2021, the 28 countries in the European Union are expected to ban single-use plastics — including straws, plates, cutlery and drink stirrers, as well as plastic sticks for cotton swabs, balloons and candy.

The latest development, announced this past week, involves the approval of a provisional agreement by the European Parliament and Council of the European Union. Formal approval is expected next. The ban carries through on an initiative launched in May that also seeks to limit the use of plastic drink cups, food containers, grocery bags and candy wrappers. Review Water Ways, May 31,2018, or take a look at this EU brochure.

Most plastic in Europe is landfilled or incinerated, rather than being recycled, which is a loss to the economy, according to EU documents contained in the European Strategy for Plastics. In the environment, many plastics take hundreds of years to break down, and the amount of plastic getting into the ocean has raised alarm bells throughout the world.

“When we have a situation where one year you can bring your fish home in a plastic bag, and the next year you are bringing that bag home in a fish, we have to work hard and work fast,” Karmenu Vella, EU commissioner for environment, maritime affairs and fisheries, said in a statement released Wednesday. “So I am happy that with the agreement of today between Parliament and Council. We have taken a big stride towards reducing the amount of single-use plastic items in our economy, our ocean and ultimately our bodies.”

“This agreement truly helps protect our people and our planet,” said First Vice-President Frans Timmermans, responsible for sustainable development. “Europeans are conscious that plastic waste is an enormous problem and the EU as a whole has shown true courage in addressing it, making us the global leader in tackling plastic marine litter.”

The measures are expected to reduce litter by more than half for the top-10 plastic litter items, saving 22 billion Euros (about $25 billion) by 2030 and avoiding 3.4 million metric tons (3.75 million U.S. tons) of carbon dioxide emissions by 2030, according to a fact sheet.

The United Nations has launched a campaign to reduce plastic pollution.

Peter Harris, a graduate of North Kitsap High School who is working on an environmental assessment for the United Nations, told me in June that plastics pollution is one of the three greatest problems facing the world’s oceans. The others are the bleaching of coral reefs caused by global warming and overfishing, which is driving some species to extinction. See Water Ways, June 6, 2018.

The European Union has carefully examined how plastics affect the ocean. EU countries should be recognized for their courage in tackling the problem in Europe, not waiting for a worldwide agreement before taking action. Non-European countries would be wise to consider their own plastic impacts on the environment.

So far, actions in the United States have been limited to a relatively small number of cities and counties, along with a few states. Because plastics wash downstream in stormwater and into rivers before reaching the ocean, every American has a role to play in the problem. Whether we address the challenges internationally, nationally or locally, everyone should take time to understand this serious issue, consider practical solutions and support actions that can save marine life before it’s too late.

Amusing Monday: Bill Gates talks toilets again

Microsoft founder Bill Gates remains obsessed with human waste — in a good way, of course. His goal is to improve sanitation throughout the world and thereby reduce suffering from disease.

Poop is a subject that never goes out of style with comedians, and Ronny Chieng of “The Daily Show with Trevor Noah” is right on top of the subject. In a conversation with Bill Gates, shown in the first video, Chieng demands to know why Gates has been carrying around a jar of human feces.

“Toilets are something that we take for granted,” Gates responds, “but billions of people don’t have them.”

The Bill and Melinda Gates Foundation is funding a major campaign to get engineers and other smart people to design a small-scale treatment device that generates energy while producing useable water. It’s called the Reinvent the Toilet Challenge.

Ronnie Chieng is asking some good questions, but I’m not sure why he needs to blurt out a bunch of four-letter words, when five-letter words like “waste” and “feces” work quite well.

“We’ve put several hundred million into this to show it can be done,” Bill says.

“Several hundred million dollars?” Ronnie responds. “Oh my god, is Bill Gates literally flushing his fortune down the toilet?”

Those who have been following Bill Gates’ efforts for a few years won’t be surprised at his desire to improve sanitation in places around the world where flush toilets are just a pipe dream.

Last month, Gates carried a jar of human feces onto the stage with him in Beijing where he addressed an audience at the Reinvented Toilet Expo.

“This small amount of feces could contain as many as 200 trillion rotavirus cells, 20 billion shigella bacteria and 100,000 parasitic worm eggs,” Gates said, as quoted by National Public Radio. His prepared speech can be found on the website of the Gates Foundation, along with a press release.

About 20 exhibitors were able to show off their inventions, including household toilets capable of internally processing small amounts of waste as well as commercial-sized treatment plants that turn waste into drinking water, electricity and ash.

Sedron Technologies, based in Sedro Woolley, is working at both ends of the spectrum. On the larger scale, its Janicki Omni Processor dries out solid waste and uses it as fuel. On the smaller scale, its new Firelight Toilet was just unveiled at the recent expo and explained in a news story by reporter Julia-Grace Sanders of the Skagit Valley Herald.

Gates discusses what he calls “clever toilet” technologies in the second and third videos on this page. In addition to NPR, the Expo was covered by Popular Science and The Hindu, which localizes the story for its audience in India where sanitation is a monstrous issue.

As I said, Bill Gates has been obsessed with this issue for quite awhile. In 2015, I featured a video about the “ultimate taste test” using sewage effluent. The tasters were Gates and Jimmy Fallon of “The Tonight Show.” See Water Ways, Feb. 9, 2015.

Hydrophones open a world of underwater sound to people at home

Listening to the sound of whales in Puget Sound from your computer at home is becoming easier than ever, thanks to a new hydrophone on Whidbey Island and its connection to a more sophisticated computer network.

Organizers anticipate that thousands of human listeners could add a new dimension to scientific studies, raise awareness about the noise that orcas endure and perhaps alert authorities when sounds are loud enough to harm marine mammals in the vicinity.

The new hydrophone (underwater microphone) at Whidbey’s Bush Point was installed last summer, but it stopped working soon after it was announced to the world in early November, when news stories appeared in print and on radio and television. The timing couldn’t have been worse, said Howard Garrett of Orca Network, a partner in the venture.

“We finally got the word out just as it crashed and just as J pod came into Puget Sound,” Howie told me. “We got it working after J pod had left.”

It appears that there was a problem with both the hydrophone itself and the power supply that runs a critical computer, experts say. I decided to wait and write about the new hydrophone when readers could go right to the Orcasound webpage and listen to the live sounds of underwater activity. With Whidbey’s hydrophone back in operation, one can now listen to sounds from two hydrophone locations using a web browser:

  • Orcasound Lab: This location on the west side of San Juan Island is a major thoroughfare for the endangered Southern Resident killer whales as they come east through the Strait of Juan de Fuca or south from the Strait of Georgia.
  • Bush Point: This location on the west side of Whidbey Island picks up the orcas as the enter or leave Puget Sound through Admiralty Inlet, their primary route to and from Central and South Puget Sound.

Sounds from hydrophones in several areas of Puget Sound have been available for years, thanks to the efforts of Val Veirs and his son Scott, affiliated with Beam Reach Marine Science, along with a host of other volunteers and organizations who have helped maintain the hydrophones. In the past, network users would need to launch a media player, such as iTunes, on their computer to receive the live audio stream. The new browser-based system requires no additional software.

One can also listen to a hydrophone at Lime Kiln Lighthouse, a favorite spot of the orcas on the west side of San Juan Island. The Lime Kiln live stream, a project of SMRU Consulting and The Whale Museum, can be heard on SMRU’s website. I’m hoping that Scott can add the hydrophone to his list. Orcasound, which is managed by Scott, still has a link to Lime Kiln that requires iTunes or another player.

At the moment, hydrophones that had been in operation at Port Townsend Marine Science Center, Seattle Aquarium and Neah Bay are out of operation for various reasons, Scott said, but he is working with folks at each location to see if the hydrophones could be brought back online using his new browser-based software. He would also like to expand the network with more hydrophones to pick up whale movements.

Scott’s vision of this hydrophone network involves using the technology to organize people to improve our understanding of orcas and other marine mammals while building a community concerned about the effects of underwater noise.

Scott said he has been surprised at the number of average people who have caught on to specific calls made by the whales. By identifying the calls, one can learn to tell the difference between fish-eating residents and marine-mammal-eating transients. More advanced listeners can distinguish between J, K and L pods. Check out Orcasound’s “Listen” page for information about sharing observations, learning about orca calls, and listening to archived recordings of calls.

One story I’ve never told goes back to 1997, when 19 orcas from L pod were in Dyes Inlet. It involves a phone call I received from my wife Sue. I was working at the Kitsap Sun office and away from my desk when the call came in. When I checked my voicemail, I heard what I thought was the mewing of tiny kittens. That made sense, I thought, because we had recently adopted two one-day-old kittens whose mother had abandoned them at birth. But the sound on my phone was not kittens after all but killer whales. My wife was in a boat on Dyes Inlet helping researchers who had lowered a hydrophone to listen to the orcas. Sue was holding up her cellphone and leaving me a voicemail from the whales.

The sound I heard on my phone was something like the following call, although multiplied by many voices:

      1. K-pod-S16-stereo

Scott told me that he would like to come up with names instead of numbers for the various calls. The one above is already being called “kitten’s mew,” although it is better known as “S16” among the scientific community. See the website “Listening for orcas” or the longer “Southern Resident Call Vocabulary.”

Orca Network is well known for collecting information about whale sightings, but now people are also reporting in when they hear the sounds of whales. That is especially helpful when visibility is poor. Both the sighting and sounding information can at times be useful to researchers who follow the whales at a distance and collect fecal samples to check out their health conditions. Observers can send notes via Orca Network’s Facebook page or via email.

Howard Garrett of Orca Network mentioned that many people are tuning in to the underwater sounds even when whales are not around. They may listen for hours with an expectation of hearing something interesting, but listeners also come to understand the world occupied by the whales.

“You get to experience what the orcas’ lives are like,” Howie told me. “It’s a noisy world for the killer whales.”

Scott agreed. “The most powerful thing that these live streams do is inspire people to listen. What they come to understand is what quiet is and that ships are the dominant source of noise out there.”

Knowing where a hydrophone is located, one can go to MarineTraffic.com and identify one or more ships that may be making the noise. “I do want people to call out outlier noise polluters,” Scott said.

Because federal funds for running the hydrophones has mostly dried up, Scott launched a Kickstarter campaign to design and get the new system up and running. It was great to learn who the supporters are, he said, noting that he knew only about a third of the people who are regular listeners. One woman in Romania became an expert in listening to the whales and wrote a paper about how to improve the hydrophone network.

“We are poised to become a much better organizer of people,” Scott said. “One option is for notifications. We can send out notifications using a new app that allows people to tune in when the whales can be heard.”

Notifications are not yet an option, but I told Scott that I would let people know when this option becomes available.

Computer programs have been developed to recognize the sounds of orcas, record various data and send out an alert, but the human brain has unique capabilities for understanding sound. Together, computers and human listeners can capture more information than either one alone. Scott said.

“I think we might have a friendly competition between humans and machines,” he noted.

Most hydrophones are designed for listening in the human range of hearing, but Scott would like to install more advanced devices capable of capturing the full vocal range of an orca. Such sounds could then be more completely analyzed. Perhaps someone will discover the still-hidden meanings of the orca vocalizations.

Legal settlement could help protect salmon eggs incubating in gravel

Washington Department of Ecology has agreed to take steps to protect wild salmon eggs incubating in gravel by developing entirely new water-quality standards to control fine sediment going into streams.

The new standards, yet to be developed, could ultimately limit silty runoff coming from logging operations, housing construction and other operations that can affect water quality. The idea is maintain adequate oxygen to salmon eggs, thus increasing the rate of survival as well as the health of the young fish.

The legal agreement with Ecology grew out of a lawsuit brought by Northwest Environmental Advocates against the federal Environmental Protection Agency. NWEA claimed that the EPA had failed to consult with natural resource agencies while reviewing changes in state water-quality standards, as required by the Endangered Species Act.

Hood Canal avoids a major fish kill following unwelcome conditions

Southern Hood Canal avoided a major fish kill this year, but for a few days in September it looked like conditions were set for low-oxygen waters to rise to the surface, leaving fish in a critical state with no place to go, experts say.

Data from the Hoodsport buoy show the rise of low-oxygen waters to the surface over time (purple color in top two graphs). // Graphic: NANOOS

Seth Book, a biologist with the Skokomish Tribe, has been keeping a close watch on a monitoring buoy at Hoodsport. Dissolved oxygen in deep waters reached a very low concentration near the end of September, raising concerns that if these waters were to rise to the surface they could suddenly lead to a deadly low-oxygen condition. This typically happens when south winds blow the surface waters to the north.

“I started asking around the community to see if anyone had seen evidence of low DO (fish at surface; dead fish; deep fish being observed or found in fishing nets at surface; diver observations) and luckily I had no reports,” Seth wrote to me in an email.
