Take special care to save carwashes from extinction

Friday, May 3rd, 2013

I used to feel happy for teenagers who got together on a weekend to wash cars and raise money for a good cause. I would often take time to drive in, get my car washed and praise the teens for their efforts. And I would give them a nice tip.

Now, when I see a charity carwash, I just want to know where the water is going. If the water is washing into a storm drain that spills into a stream, I can’t help but wonder if these kids care about fish and wildlife, or if they might not have gotten the message about the harm caused by dirty, soapy water.

You may wish to read the story I wrote on this topic in last Saturday’s Kitsap Sun.

Sometimes, being an environmental reporter causes one to think a little too much about the environment. Sure, carwashes probably are not going to kill everything in sight. But they are just another insult from a human society that has not yet learned how to protect the living Earth.

The federal Clean Water Act of 1972 declared that it was illegal to discharge polluted water into any natural stream or waterway. At the time, industrial discharges were so severe that soap and heavy metals from carwashes were insignificant. But now, after 40 years, those industrial point sources are greatly diminished, and researchers are learning that the greatest threat to water quality today comes from thousands of small sources.

Gov. Jay Inslee has declared this month “Puget Sound Starts Here Month,” according to a press release issued by the Puget Sound Partnership. The idea is for each of us to pay attention to how we affect Puget Sound.

Here’s the message from Marc Daily, the partnership’s interim executive director:

“It’s not just about the pipe coming out of the factory anymore. Today, stormwater runoff is the single largest contributor to our water quality problems. That pollution comes from our cars and how we wash them, from the chemicals we put on our lawns, and from not picking up after our pets. When it rains, bacteria and toxic chemicals from these and other sources end up in our local waterways. That’s a problem.”

One way to keep charity car washes alive is to capture the wash water and direct it into a toilet or sink that connects to a municipal sewer system, not a septic system. King County provides instructions for making and using a carwash kit to handle the water.

People can also sell tickets to commercial carwashes, which is the method being pushed by most water-quality programs across the nation. It’s not just here that carwashes are getting increasing attention.

How much harm do they cause? It varies from place to place, but some students from Central Kitsap High School calculated the amount of various chemicals produced by capturing the water from washing cars and conducting lab tests on some of the pollutants. See “Characterization of Runoff from Charity Carwashes in the Dyes Inlet Watershed” (PDF 475 kb).

Like many people, I feel a tinge of sadness that carwashes will probably die out. Like many harmful traditions, such as burning garbage and smoking, it might be time to give this one up.

Still, if you want to operate a weekend car wash, get yourself a carwash kit to deal with the wash water. Then stand on the corner and wave signs promoting the fact that this is a clean and safe carwash that protects the environment. If I see you, I’ll even stop and donate to the cause.


‘Don’t Drip and Drive’ offers one approach to oil leaks

Tuesday, April 9th, 2013

I would like to share some comments from a story along with an editorial cartoon, but first I want to talk about rain runoff from streets, driveways, parking lots, yards and roofs — also known as stormwater.

Stormwater is considered the greatest pollution threat to Puget Sound, according to studies by the Washington Department of Ecology. Of course, it is not the rain itself that causes the problem. It is what gets picked up along the way: chemicals, pesticides, fertilizers, bacteria … The list goes on.

Among the toxic chemicals, one of the biggest problems appears to be motor oil from vehicles. Oil leaks out of cars as they are moving down the road or while they are parked, then the rains wash the pollution into the nearest ditch and eventually into Puget Sound. By some estimates, that amounts to 7 million quarts of oil each year.

Fortunately, not all the oil goes into the water. In Kitsap County, for example, city and county street sweepers are driving around, picking up some of the oil and other chemicals along with soil particles on the roads. It is a proven effort to reduce pollution.

It would be better still if the oil didn’t get on the roads or parking lots in the first place. But how do you get people to fix the oil leaks in their cars?

An organization of local governments throughout the Puget Sound region is hoping that awareness will provide one answer. More than 80 service shops in the region have agreed to check for oil leaks at no cost or obligation to anyone. See my story in last Tuesday’s Kitsap Sun.

It’s a pilot program with the clever title “Don’t Drip and Drive.” It will run through April. The cost to the government is the cost of advertising on the radio. A federal stormwater permit issued to local governments throughout the region already requires that they try to educate the public. Maybe this campaign will work; maybe it won’t. I’ll report on the results after the program is over.

It seems like a simple approach to the problem. Even if people know their cars are leaking, this program encourages them to think about solutions. Why not get a free estimate to see what it would cost to fix the leak? Maybe it won’t cost much. Maybe a few people will find a way to address the problem sooner rather than later. Maybe it will reduce wear on their vehicles.

If people become informed and are offered a free, no-obligations solution, will it make a difference? I hope it does, because it avoids the more heavy-handed ideas, such as requiring vehicle inspections to obtain a car license.

If you read some of the comments at the end of the story, however, you might think this pilot program is intruding into people’s personal lives, not just asking them to check for oil leaks. I realize that the comments section can be a dark place, occupied by people who see a full glass as empty. But it is amusing to see what bothers some people.

Here are the first few comments:

“I would guess that 99% of drivers park their vehicle in the same spot in their driveway or garage every night. Do we need a government program so they won’t have to look at that spot to see if oil has dropped there?”

“I agree! Government is way outside of what they are supposed to be. This is ridiculous and out of control.”

“Yep so they find a leak and what’s next??? Big time repair bill and just in time to keep your wallet empty! Nice program! Big goverment (sic) get out of my life will you???”

Sometimes a picture is worth a thousand words, so I’d like to share with you an editorial cartoon by Milt Priggee published in Sunday’s Kitsap Sun.

Highway runoff can kill coho before they can spawn

Thursday, January 24th, 2013

Stormwater runoff from highways has been found to contain one or more toxic compounds that can bring on sudden death in coho and possibly other salmon as well.

Researchers from NOAA’s Northwest Fisheries Science Center first noticed the problem in Seattle’s Longfellow Creek, which gets a high volume of stormwater when it rains. Returning adult coho were dying in the stream before they could spawn.

The problem was confirmed last fall at Grover’s Creek Hatchery in North Kitsap, where coho were placed into tanks containing highway runoff. Even after days of rain, the runoff was deadly, causing the fish to become disoriented and die within hours. This was not a disease process but a severe physiological disruption of the salmon’s metabolism.

On Monday, I reported on these dramatic new findings made by Nat Scholz and his colleagues at NOAA. Since then, the story was picked up by the Associated Press and has appeared in dozens of publications and news digests across the country.

I won’t go into detail about the study here, because most of what I know is the story. See Kitsap Sun, Jan. 21. Toward the end, I describe some actions that Kitsap County officials are taking to keep highway dirt and debris from getting into local streams, even before the deadly compounds are identified.

I’ll continue to follow this story as scientists try to narrow down the list of possible toxic compounds that are causing the problem. The next step will be to take clues from tissues removed from the dying salmon at Grover’s Creek Hatchery.

Naturally, these new findings raise many questions about how the unknown chemicals affect the fish so rapidly and where these compounds come from. Could it be from automobile tires or exhaust, or could it be something in the road material itself? Are certain chemicals acting synergistically to heighten the problem? Answering these questions could make a significant difference for urban streams and possibly for rural streams as well.

Personally, I can’t help wondering about the salmon that survive. It’s not easy to find a coho stream where highway runoff does not contribute something to the flow. If these compounds can kill a fish in concentrations found in stormwater, what are they doing to fish exposed to lower concentrations? Are the salmon that survive as successful in finding a mate and conducting their spawning rituals as salmon not exposed at all?

I’m not sure where this line of research will lead, but the early implications appear to be quite serious. On an optimistic note, if the compounds can be identified, Washington state has a reputation for reducing or eliminating toxic chemicals at the source.


Shooting down excuses to permeable pavement

Saturday, June 30th, 2012

Lisa Stiffler of Sightline Institute does an excellent job addressing common objections to permeable pavement in her latest discussion about stormwater solutions. See Sightline’s website.

I’ve heard the excuses from contractors worried about the use and maintenance of new paving materials. Lisa did some research and tells us that when the concerns are valid, there may be ways to work around the problems.

The fears she allays, including sources for more information:

  • Permeable pavement will clog and lose its porousness.
  • Holes in permeable pavement make it weaker.
  • Permeable pavement won’t work on high-speed, high-volume roads such as highways.
  • Permeable pavement won’t work on sloped sites.
  • Permeable pavement will result in groundwater contamination.
  • Permeable pavement is prohibitively expensive.
  • Permeable pavement is more prone to rutting, breaking apart, or otherwise failing.

The latest post is part of Lisa’s ongoing discussion called “Stormwater Solutions: Curbing Toxic Runoff.”


Studies look at effects of stormwater on salmon

Tuesday, December 6th, 2011

It’s the water, or maybe it’s just the nasty stuff that’s in the water.

A new series of studies by federal researchers is delving into the question of which pollutants in urban streams are killing coho salmon.

As I describe in a story in today’s Kitsap Sun, the new studies involve coho returning to the Suquamish Tribe’s Grovers Creek Hatchery in North Kitsap.

Of course, pollutants in streams are just one factor affecting salmon in the Puget Sound region, where development continues to alter streamflows and reduce vegetation, despite efforts to protect and restore habitat. But pollution may play a role that has gone largely unnoticed in some streams.

The new studies continue an investigation that began more than a decade ago with the involvement of numerous agencies. By now, most of us have heard about the effects of copper on salmon, but the latest round of studies will look at the collection of pollutants found in stormwater to see how they work together. It may be possible to pinpoint the chemical concentrations that result in critical physiological changes in salmon.

The latest work involves a team led by David Baldwin of NOAA Fisheries and Steve Damm of the U.S. Fish and Wildlife Service. The Suquamish Tribe is providing the fish, along with facilities and support.

For information on the ongoing effort to understand how toxic chemicals affect salmon, review these pages on the website of the Northwest Fisheries Science Center:

returning to spawn in restored urban streams

The impacts of dissolved copper on olfactory 
function in juvenile coho salmon

Mechanosensory impacts of non-point source pollutants in fish

to polycyclic aromatic hydrocarbons

A page called “Coho Pre-spawn Mortality in Urban Streams” presents a series of videos that show the advance of an apparent neurological disease that first causes disorientation in coho salmon and then death. The video is taken in Seattle’s Longfellow Creek, an urban stream.


Following the money into raw sewage overflows

Sunday, July 31st, 2011

Water-quality leaders in the Washington Department of Ecology and U.S. Environmental Protection Agency were quick to respond yesterday to a Seattle Times’ story, which begins:

“Seattle and King County are poised to spend more than $1.3 billion of ratepayer money on pollution-cleanup programs that won’t even move the water-quality needle in Puget Sound.”

Yesterday’s story, by reporter Linda Mapes, is about combined sewage overflows — something that Bremerton knows a little about, having completed a cleanup program after 20 years and $50 million in expenditures. See my story from May 30 in the Kitsap Sun.

The premise of Linda’s story is that it might be better for local governments to focus on reducing stormwater overall rather trying to meet a 1988 state pollution standard focused on raw sewage discharges. After all, the reasoning goes, stormwater containing toxic chemicals may be worse for Puget Sound than stormwater mixed with sewage.

The state requirement, by the way, limits discharges of raw sewage in stormwater to one overflow per year, on average, for each outfall pipe.

There is plenty of room for disagreement, as the Times’ story points out. Christie True, director of King County Natural Resources and Parks, stresses that upcoming CSO projects will reduce the public’s exposure to untreated sewage. But Larry Phillips, a member of the King County Council, says dollars spent on CSO projects can’t be spent on buying habitat or attacking the surface-runoff problem, which the Puget Sound Partnership has deemed the region’s top priority.

Bill Ruckelshaus, the first administrator of the EPA and former chairman of the Puget Sound Partnership’s Leadership Council, was quoted as saying:

“This is just crazy; we don’t have unlimited funds in this country, and whatever we do, we ought to spend where we get the most bang for the buck … Cost-benefit has not been part of the discussion.”

David Dicks, former executive director of the partnership and now a member of the Leadership Council, said this:

“It’s just momentum. And what you learn in these things is you can go in and scream and yell and be a revolutionary for a while, but the institutional momentum of these laws has a lot of power, and it is just dumb power. … What we need to do is turn off the autopilot and see what makes sense here.”

Ecology and EPA officials took a stand in favor of the existing rules for reducing sewage discharges. Both issued quick responses to the Seattle Times article, writing on a blog called ECOconnect

From Kelly Susewind, manager of Ecology’s Water Quality Program:

“Infrastructure investments are needed to address water pollution caused by both CSO and stormwater discharges. In areas served by combined systems, CSO projects provide solutions to both CSO and stormwater pollution.

“The investments ratepayers make in their communities’ CSO programs protect public health and Washington’s waters, two principal missions of sewer and stormwater utilities. The success of these projects advances the goals of our state and federal laws to protect, clean up and preserve our waters for present and future generations.”

Adds Dennis McLerran, EPA’s regional administrator:

“Discharging large amounts of raw sewage to Puget Sound and Lake Washington is simply not acceptable. That’s why EPA has worked closely with the state, King County and Seattle over many years to address sewage treatment and the ongoing problem of Combined Sewer Overflow (CSO) pollution. With that work nearly completed, now is not the time to lose our resolve to finish the job visionary leaders in the Puget Sound region started some 40 years ago.”

Shellfish were not mentioned in this discussion — maybe because it was focused on Seattle and King County, where industrial pollution is a major problem. In Kitsap County, shellfish are worth millions of dollars a year to the local and regional economy. For Dyes Inlet, the reopening of shellfish beds probably would not have happened except for a lawsuit that forced the city of Bremerton to comply with the federal Clean Water Act on a strict time schedule.

Lisa Stiffler, former PI reporter who now works for Sightline Institute, discussed Bremerton’s accomplishment with a focus on the cost. See “How Bremerton cleaned its waters, and came to wonder about the costs” in the online publication Crosscut.

A case can be made that shellfish beds in Dyes Inlet could have been cleaned up enough to be reopened by spending just the first $33 million, thereby saving the extra $17 million that it took to bring the city into full compliance with federal law.

But state and county health officials have told me on many occasions that Bremerton and Kitsap County, along with local residents, must continue to work hard to keep the Dyes Inlet shellfish beds open. Beaches in the inlet remain on the verge of closure again, and population growth tends to exacerbate the bacterial pollution.

Kitsap County Health District is respected for its monitoring and pollution-fighting program, but it does help to know that release of raw sewage into the inlet has become a very rare event.

Lisa makes a good point when she says Bremerton would have saved money if engineers would have known more about low-impact development during the planning for CSO reductions. Infiltrating rain water near the source (preferably before it runs off the property) reduces the need to deal with stormwater flowing through pipes. Keeping stormwater out of sewer lines by using LID techniques effectively allows the pipes to carry all the sewage to the treatment plants, even during heavy rains.

Bremerton has become a leader in LID. If city officials had known 20 years ago what they know today, they probably would have spent more on pervious pavement and rain gardens and less on expensive piping networks. But it appears they did their best with the knowledge they had — and LID has become a major part of ongoing efforts to address stormwater.

Cities still working on CSO problems may find Bremerton’s experience helpful. Keeping stormwater out of pipes is proving effective, whether or not those pipes also contain sewage.


Watching the water-quality report cards

Thursday, June 30th, 2011

I guess we’re lucky in Kitsap County to have local health authorities who not only gather water-quality data but also know what to do with the information. I’m told that’s not the case for many counties in Washington state or across the nation.

The reason I bring this up is because of a story I wrote for today’s Kitsap Sun. Some of the water-quality report cards being issued by environmental groups are nothing more than a rewrite of raw data from water-quality samples collected by local officials. This could be valuable information in places where no other information is offered. But water-quality specialists at the Kitsap County Health District stand ready to interpret the data and take more samples, if necessary, so we know when we really should worry.

One bad sample does not mean we should run away from the water, but it does serve to raise some questions. Asking questions is the role I play when I see these reports. Fortunately, we have experts in Kitsap County who know our streams and beaches and who are willing and able to answer my questions.

It would be interesting to know how many counties in the state conduct routine monitoring of streams, lakes and marine waters; how many do follow-up tests when they find a problem; how many assess the findings to measure trends; and how many use the data to begin corrective actions. If anyone knows of information compiled on monitoring programs for all counties or cities, please let me know. If not, maybe this would be a project someone could take on.

Kitsap County’s monitoring program is funded by a stormwater fee collected with our property taxes. The residential fee is $70 per year. Commercial businesses may pay more, depending on their size.

Many cities and counties collect stormwater fees, but few use the money for monitoring. Even fewer compile long-term trends with a comprehensive ongoing monitoring program. Such programs deserve consideration.

In addition to paying for water-quality testing, Kitsap County’s stormwater fee is used to investigate sources of pollution; retrofit older communities with stormwater systems; clean out storm drains on county property; inspect all storm drains except for state highways; teach people about clean water; coordinate volunteers in programs including Beach Watchers and Stream Stewards; provide signs and supplies for the Mutt Mit dog-waste cleanup program; fund grants for a backyard rain garden program; and plan for and monitor results of stream-restoration and stormwater-retrofit projects.

I’m not saying that programs such as Heal the Bay and Testing the Waters (by Natural Resources Defense Council) don’t have value. In some cases, this is all that communities have, and they provide a good reason to ask questions about water quality.

But, as Keith Grellner of the Kitsap County Health District told me, these reports may be like crying wolf for some individuals. If people keep hearing warnings when the problems are minimal or nonexistent, will they pay attention in the face of serious water-quality concerns?


New study refines Puget Sound pollution issues

Wednesday, May 18th, 2011

A third-generation study of toxic pollution in Puget Sound claims to be the best estimate so far of total amounts of toxics entering Puget Sound each year.

New report on toxics in Puget Sound (PDF 7.3 mb). Click to download.
Washington Department of Ecology

As Craig Welch of the Seattle Times points out in a story today, it’s a big exaggeration to think that Puget Sound is suffering through enough drips and drabs of oil — largely from vehicles — to equal an Exxon Valdez spill every two years.

Craig is right to point out how previous studies overestimated the amount of several toxics. After all, politicians having been tossing around the dramatic Exxon Valdez analogy when it serves their purposes. Still, the total amount of oil or any other pollutant in Puget Sound is not really a good measure of the problems we face.

If you want to understand pollution in a waterway, it’s better to measure the concentration of the pollutant, see where that level falls on a toxicity scale, then consider how fish and other organisms are exposed to the pollution.

The new study for the Department of Ecology, titled “Toxics in Surface Runoff to Puget Sound,” analyzed 21 chemicals or groups of chemicals in 16 streams in the Puyallup and Snohomish river watersheds. The watersheds contain all different land types — commercial-industrial, residential, agricultural, forest, fields and other undeveloped lands. The idea is that researchers could extrapolate from these land types to represent all of Puget Sound. But such an extrapolation still requires a number of assumptions, which can throw off the estimates by wide margins.

At least we can say the latest study involved actual water-quality sampling. Previous estimates — including those that produced the Exxon Valdez analogy — were based on measurements of stormwater in other parts of the country.

Sinclair-Dyes study: How to get ahead of pollution

Friday, May 6th, 2011

The soon-to-be-released cleanup plan for Sinclair and Dyes inlets could become a leading example of how to reduce all kinds of pollution in a waterway. Check out my story in Tuesday’s Kitsap Sun.

Based on conversations with many people involved in the project, I believe the keys to success are continual and ongoing monitoring of water quality, an unfailing commitment to identify pollution sources, and a spirit of cooperation with people who can help solve the problems.

Officials with the Kitsap County Health District and other local and state agencies will tell you that one can never walk away from a watershed with the belief that the pollution problem is solved. Still, at times, the rewards can be relatively quick, as one observes improvements in water quality after a pollution source is turned off.

Every month for the past 15 years, health district officials have gone out into the field and taken water samples from nearly every stream in Kitsap County — some 58 streams at last count. Often, these monthly tests provide assurance than cleanup plans are working. Occasionally, they offer an early warning that someone in the watershed is doing something to degrade water quality.

If you haven’t checked the health district’s Water Quality website, I would recommend reading through some of the reports under “Featured Water Quality Reports,” particularly the “2010 Water Quality Monitoring Report.”

Monthly water-quality testing over time tells a story about differences between wet years and dry years, about the effects of new development, and about successes that follow cleanup of problem farms, septic systems or yards containing dog feces.

I think it would be a big step forward if every significant stream in the state were monitored monthly for at least bacterial pollution. The results would help all levels of government set priorities for dealing with stormwater and other pollution sources.

Another factor worth mentioning in regard to the Sinclair-Dyes cleanup is the Navy’s funding for Project Envvest, a cooperative effort between the U.S. Environmental Protection Agency, Washington Department of Ecology and the Navy. The resulting computer model helped describe the flow of pollution under various rainfall scenarios. It can even predict the movement of pollution resulting from various kinds of spills.

The animation (right) shows what would happen if the ultraviolet infection system were to fail in the East Bremerton treatment plant, which handles stormwater mixed with sewage during periods of heavy rainfall. Tidal flows make a big difference. This simulated spill is 7,000 gallons per minute for a total of 10 million gallons. See CSO Simulation Scenarios to view other animations from the model.

Recession pushes and pulls on Puget Sound cleanup

Thursday, October 21st, 2010

In some ways, the recession we are going through has been very good for Puget Sound, at least if we’re talking about ecosystem restoration.

Gov. Chris Gregoire spies an eagle flying over Oakland Bay during Friday’s media tour.

In an effort to stimulate the economy and create jobs, Congress appropriated lots of money for projects that were ready or nearly ready to be built. The Puget Sound Partnership lists 614 projects with a price tag of $460 million since 2008. An estimated 15,640 jobs were created in the process, according to the PSP.

But the recession also helped another way. It turns out that when restoration and public-works projects were put out to bid, most of them came in well under their original estimates. Contractors apparently needed the work so badly that they were willing to cut their profit margins and compete hard for the available work. That freed up money for additional projects.

On Friday, Gov. Chris Gregoire led a media tour to some of the projects being built with special federal and state appropriations. One was the Belfair sewage treatment plant, designed to remove nitrogen from Hood Canal to address the low-oxygen problem. Her message was that Puget Sound restoration must not be placed on the back burner until the recession is over.
