Greater Vancouver
Greater Vancouver:
Stop Pretending the Fraser Carries Your Pollution Away
The storm drain outside your home is connected to something bigger. Roads, parking lots, industrial lands and neighbourhoods drain into streams and rivers. The Fraser carries water, sediment and contaminants into the Strait of Georgia and through the Gulf Islands. That connects Greater Vancouver's streets to shellfish beds, forage fish, salmon, birds, wildlife and endangered Southern Resident killer whales.
Greater Vancouver needs to have an uncomfortable conversation about its own backyard.
Not Alberta's pollution. Not somebody else's mine. Not tankers somewhere offshore.
Our roads. Our industrial lands. Our parking lots. Our construction sites. Our aging infrastructure. Our leaking vehicles. Our storm drains. Our outfalls.
A storm drain is not a magic hole where pollution disappears.
It is the beginning of a journey.
Rain falls on pavement. It picks up sediment, tire and brake wear, oil, grease, litter, metals, chemicals, pet waste and everything else we leave behind. Much of that water enters storm drains and eventually reaches creeks, rivers or the ocean.
And across the Lower Fraser, all roads eventually lead to one enormous receiving environment:
The Fraser River and the Salish Sea.
For decades, governments and scientists have documented the problem.
So in 2026 the public should be asking a different question.
What are we actually doing to stop pollution before it reaches the water?
We Saw the Problem From the Air
This investigation did not begin because Veins of Life Watershed Society wanted to write another report.
It started while we were working.
During our work up the Fraser and its tributaries — including work around the Alouette River, Katzie Nation, McBarge, abandoned vessels and marine debris — we were using drones to survey portions of the river system.
From the air, some discharges caught our attention.
We saw several outfalls where the water entering the river or tributaries looked noticeably different from the surrounding water. At some locations there were strong signs of turbidity. At others we saw what appeared to be oil-like sheen.
So we went down and took a closer look.
Decades of working around stormwater, contaminated sediment, industrial drainage and restoration told us something was worth investigating.
A brown plume does not identify a chemical.
A surface sheen does not automatically prove an environmental offence.
But when you see something abnormal coming from a pipe into fish-bearing water, you don't shrug and walk away.
You ask questions.
That is exactly what we did.
In August 2023 we wrote to municipalities, regional districts, federal and provincial agencies and environmental organizations asking who was monitoring the Fraser's storm water outfalls and, more importantly, who was following contamination back to its source. Our correspondence recorded that the outfalls we had seen during Fraser surveys had triggered our concern and that current information was proving surprisingly difficult to find.
And we wrote something then that remains our position today:
Source control. Source control. Source control — before restoration or reclamation.
That Fraser Fieldwork Led to Our Pacific Salmon Foundation Project
Those observations didn't end with a few emails.
They helped lead to our Lower Fraser stormwater and source-control review undertaken in collaboration with the Pacific Salmon Foundation.
The project looked beyond one suspicious pipe.
We wanted to know what municipalities throughout the Lower Fraser were actually doing about storm water.
We reviewed existing guidance and policies. We looked at stormwater impacts on salmon. We interviewed municipal staff. We compared source-control bylaws, green infrastructure, monitoring, catch-basin maintenance, street sweeping and pollution-response programs.
The municipalities participating in the interview work included Vancouver, North Vancouver, New Westminster, Coquitlam, Burnaby, Delta, White Rock, Pitt Meadows and Richmond.
What emerged was not a story of municipal employees doing nothing.
There is good work happening.
There are rain gardens, bio swales and green streets.
There are sewer-separation projects.
There are monitoring programs.
There are stream keepers.
There are environmental staff who care deeply about their watersheds.
There are municipalities experimenting with better ways of handling rainwater.
But our review exposed a fundamental weakness:
Greater Vancouver does not operate as one watershed when it comes to storm water pollution.
Programs vary municipality by municipality.
Some monitor much more than others.
Some clean infrastructure more frequently.
Some have stronger environmental teams.
Some have better data.
Some practices remain largely reactive.
Funding and staffing vary dramatically.
And although sanitary sewage and wastewater discharges are heavily regulated and monitored, our review found nothing comparable to a consistent Lower Fraser-wide system for monitoring stormwater outfalls and connecting those results directly to source control.
Our report put it plainly: water-quality monitoring was often concentrated in creeks and individual watersheds while the connection to downstream receiving waters — including the Fraser River, Burrard Inlet and Boundary Bay — could be overlooked.
That is a major problem when the river receiving all this water doesn't stop at the municipal boundary.
And the Fraser Doesn't Stop at Richmond
Greater Vancouver cannot honestly pretend we do not know where Fraser River water goes.
Scientists have been studying that question for generations.
Satellite work in the 1970s physically tracked Fraser sediment plumes across the Strait of Georgia. Researchers observed Fraser plumes reaching Porlier, Active and Boundary passes, with flood tides carrying the plume northwest along the northern coast of Galiano Island. (EPA Nepis)
Those are the Gulf Islands.
This is not a theoretical computer model produced last week.
Scientists were watching Fraser sediment move through this system almost half a century ago.
Researchers later analyzing suspended Fraser sediment and sediment cores from the Fraser estuary, Vancouver Harbour and Strait of Georgia found the Fraser River to be the predominant source of natural and anthropogenic hydrocarbons to the Strait, with the Fraser's natural hydrocarbon burden augmented principally by petroleum hydrocarbons and combustion PAHs from Vancouver. (PubMed)
So when somebody says:
"The Fraser is a big river. It all gets diluted and goes away."
The question is:
Away to where?
There is no "away."
There is downstream.
Downstream Is Somebody Else's Backyard
Downstream is the Fraser estuary.
Downstream is the Strait of Georgia.
Downstream is Galiano, Mayne, Pender, Saturna, Salt Spring and the surrounding Gulf Islands.
Downstream is beaches.
Shellfish beds.
Forage-fish habitat.
Salmon migration routes.
Bird habitat.
Marine mammal habitat.
And eventually, somebody's dinner plate.
That does not mean every contaminant detected at every Gulf Island location originated from Greater Vancouver.
Local sewage, boating, agriculture, historic contamination, individual properties and other sources also matter.
But we are long past pretending the Fraser isn't one of the major physical pathways connecting Greater Vancouver to the marine environment.
Why Should a Family in Burnaby or Surrey Care About a Shellfish Bed in the Gulf Islands?
Because this is one ecosystem.
Clams, mussels and oysters are filter feeders. They process surrounding water and can accumulate contaminants and disease-causing organisms from it.
Canada's shellfish-safety program specifically recognizes urban runoff as a potential non-point source of shellfish contamination, and federal guidance identifies chemical contaminants including heavy metals, pesticides and petroleum hydrocarbons as potential human-health concerns. (Canadian Food Inspection Agency)
Eating contaminated shellfish can make people seriously ill, and DFO warns that bivalve contamination closures are a public-health measure because contaminants and pathogens can accumulate in shellfish tissue. (PAC Atlantic)
Heavy rainfall makes this connection even more obvious. Federal shellfish guidance recognizes that significant rainfall can cause sewage-system overflows and wash pollution from land into receiving waters, contaminating nearby shellfish areas. (PAC Atlantic)
So stormwater is not simply an engineering problem.
It is potentially a food-safety problem.
A human-health problem.
A fisheries problem.
A wildlife problem.
And an economic problem when harvesting areas cannot safely be used.
Then There Is the Little Fish Almost Nobody Talks About
We keep coming back to the Pacific sand lance for a reason.
Sand lance are small.
They're not glamorous.
You don't see television fundraising campaigns built around them.
But they are one of the little gears that keeps the Salish Sea food web turning.
Research in Puget Sound describes Pacific sand lance as a critical forage species connecting plankton to larger fish, marine birds and marine mammals. NOAA-supported work has identified sand lance as second only to Pacific herring in dietary importance for Puget Sound-origin Chinook salmon in the studied populations. (USGS)
USGS research has also found legacy and current-use contaminants in Pacific sand lance collected around Puget Sound. Scientists have studied PCBs and other contaminants because forage fish can move pollution up the food web into the predators that eat them. (USGS)
And sand lance matter to far more than salmon.
They feed fish.
They feed seabirds.
They contribute to marine mammal food webs.
They are one of the connections between the health of nearshore sediments and the animals Greater Vancouver residents say they want protected.
Sand Lance. Chinook. Orcas. This Is Not Complicated.
Chinook salmon are a primary prey species for endangered Southern Resident killer whales.
Canada itself identifies three major threats to Southern Resident recovery: reduced prey availability, vessel disturbance and contaminants. (Canada)
Environment and Climate Change Canada says Southern Residents and their Chinook prey are exposed to contaminants through pathways that include municipal and industrial wastewater and urban and agricultural runoff. Because killer whales are long-lived predators high in the food web, some pollutants can build up through their environment and prey. (Canada)
This isn't an environmental organization's theory.
It is the federal government's own problem statement.
And the list of contaminants the federal Southern Resident technical working group considers important is sobering.
For Chinook, contaminants of major concern include PCBs, DDT, PFOS, PFOA, copper, phthalates, bisphenols and current-use pesticides. Other concerns include PBDEs, mercury, pharmaceuticals, PAHs, hydrocarbons, cadmium, lead, microplastics and other substances. (Canada)
Meanwhile, federal work in the Fraser estuary has examined more than 400 analytes in water, sediment, juvenile Chinook tissue and wastewater effluent, with some detected compounds exceeding environmental guidelines or toxicity reference values. (Canada)
That should put the argument to bed.
We know contaminants matter.
We know salmon matter.
We know Chinook matter to Southern Residents.
The debate should now be about reducing pollution.
Across the Strait, the CRD Shows Why Monitoring Matters
Greater Vancouver does not have to start from scratch.
Look across the Strait.
The Capital Regional District has operated a regional storm water-quality monitoring program since the late 1990s, building a long-term record of storm drains, creeks and receiving environments.
Today, CRD monitoring covers more than 500 locations in storm drains, creeks, harbours and nearshore marine waters. Its purpose includes identifying contamination sources and assessing potential effects on environmental and human health. (Capital Regional District)
Importantly, that work doesn't end at Victoria.
The CRD publishes stormwater-quality information for the Southern Gulf Islands as well. Its current document library includes a 2023–2024 Southern Gulf Islands Electoral Area Stormwater Quality Program report. (Capital Regional District)
Is the CRD program perfect?
Absolutely not.
And we have spent plenty of time criticizing what happens — or doesn't happen — after a bad result is found.
But the program provides something enormously valuable:
A baseline.
Year after year.
Location after location.
When a storm drain repeatedly shows concern, there is a record.
When somebody says an environmental problem is new, the old data can be checked.
When government says there is no evidence, organizations like ours can open the reports and start asking uncomfortable questions.
The CRD data gives community groups, First Nations, scientists, residents and journalists something stronger than suspicion.
It gives us data with which to raise hell.
And that is exactly what public environmental monitoring should do.
But Monitoring Alone Doesn't Stop Pollution
Here is where the CRD example becomes especially useful.
Across most of the capital region, stormwater regulation remains primarily a municipal responsibility. The CRD conducts important monitoring, but there is not one CRD-led regulatory stormwater source-control program covering every municipality.
The important exception is the Saanich Peninsula, where Central Saanich, North Saanich and Sidney have a CRD-delivered stormwater source-control service under Bylaw 4168. (Capital Regional District)
That distinction matters.
The CRD's separate Regional Source Control Program is largely concerned with what businesses and institutions put into the sanitary sewer system.
Stormwater is different.
CRD itself notes that stormwater is generally regulated by the municipality where the storm drain is located, except for the Saanich Peninsula arrangement. (Capital Regional District)
So the CRD teaches us two lessons at once:
Monitoring works.
And:
Monitoring is not enough.
A report showing a contaminated outfall does not make the contaminant disappear.
Somebody eventually has to stop the source.
That Is What We Mean by Source Control
Source control sounds complicated because governments have a remarkable ability to turn two words into a 400-page manual.
The principle is much simpler.
Stop pollution before it gets into the environment.
That's it.
If oil can be stopped before it enters a storm drain, do that instead of trying to remove it from a river.
If sediment can be kept out of a drain, do that instead of dredging contaminated sediment from an estuary years later.
If road grime can be removed from a street before rainfall carries it into salmon habitat, remove it there.
If garbage can be captured before it reaches the river, capture it there.
If somebody is sending dirty water into a storm drain, stop it there.
The farther pollution travels, the harder and more expensive it becomes to deal with.
And once it is mixed into river sediment, marine sediment, shellfish or the food web, we've allowed a relatively simple pollution-prevention problem to become an environmental restoration problem.
Washington State Has Been Doing This for More Than 20 Years
This is another reason Greater Vancouver cannot say the problem is too complicated.
Look south.
Washington State has been working systematically on urban stormwater for more than three decades.
The Washington Department of Ecology's stormwater-management manuals for the Puget Sound Basin go back to 1992, and its municipal stormwater-permit history goes back to 1995. Source-control practices were already formalized in later Western Washington manuals, including the 2005 source-control volume, and the program continues today. (Washington State Department of Ecology)
Washington now requires many municipal governments in western Washington to manage stormwater so that runoff does not pollute downstream waters. Its programs include pollution prevention, source control, stormwater maintenance, illicit-discharge work, education and monitoring. (Washington State Department of Ecology)
And Washington has spent years connecting stormwater to the health of Puget Sound salmon, shellfish and killer whales.
Our Lower Fraser report with the Pacific Salmon Foundation specifically looked across the border for lessons.
We examined examples from Seattle, Kitsap County and the Dyes Inlet area, Olympia and the wider Puget Sound region because they demonstrate what happens when stormwater is treated as an ongoing public service rather than an occasional environmental project.
The lesson isn't that Washington has solved stormwater pollution.
It hasn't.
Washington State itself still calls urban stormwater a major threat to water quality. (Washington State Department of Ecology)
The important lesson is that they stopped pretending this was a temporary problem.
They built stormwater programs around it.
And they have kept improving them for decades.
Some of the Solutions Are Almost Embarrassingly Simple
Not every solution requires a billion-dollar treatment plant.
Some pollution prevention is basic housekeeping.
Our Pacific Salmon Foundation work identified several of these "low-hanging fruit" measures, and Washington has been studying and using the same kinds of practices for years. Washington Ecology is still studying how street sweeping can reduce pollutant loads, including tire-related 6PPD-quinone entering stormwater. (Washington State Department of Ecology)
For an ordinary resident, business owner or taxpayer, the common-sense examples are easy to understand:
Clean and vacuum catch basins regularly, with at least annual attention to higher-risk locations rather than waiting until they're full or flooding.
Sweep streets regularly, and more often around heavy traffic, industrial and commercial areas where road grime and contaminated sediment accumulate.
Use simple screens, nets and debris-catching systems where appropriate to keep plastics, bottles, garbage and smaller debris from travelling through drains and into waterways.
Keep oil, paint, chemicals, concrete wash, sediment and other waste out of storm drains.
Don't wash your vehicle on the street or driveway where the soap, oil, brake dust and road grime run straight toward a storm drain. A commercial car wash is better; if you wash at home, washing over a lawn or vegetated area keeps the wash water away from the storm drain. King County gives essentially the same advice to Puget Sound residents. (King County)
None of this is revolutionary.
That's the point.
We should not be waiting for revolutionary technology to start doing obvious things.
Citizens Have a Role — But Don't Let Government Hand You the Bill and Walk Away
People can help.
Pick up litter.
Don't pour anything into a storm drain.
Keep vehicles from leaking.
Think about where wash water goes.
Support rain gardens and green spaces.
Ask what that pipe at the end of your street drains into.
But this cannot become another campaign where governments tell citizens to use a reusable coffee cup while enormous municipal and industrial drainage systems continue operating without adequate pollution control.
Individual responsibility matters.
Institutional responsibility matters more.
Municipalities manage roads, drainage systems and thousands of catch basins and outfalls.
Metro Vancouver has regional responsibilities.
British Columbia has environmental responsibilities.
Environment and Climate Change Canada is the federal lead for the pollution-prevention provisions of the Fisheries Act.
DFO has fish, fish-habitat, salmon and killer-whale responsibilities.
When DFO responded directly to us in 2023, it confirmed that ECCC is the federal lead for administration and enforcement of the Fisheries Act pollution-prevention provision and told us that federal scientists were studying contaminants in Fraser freshwater, sediment and juvenile Chinook specifically to understand contaminant sources and support measures such as additional source controls.
So nobody gets to say this is somebody else's problem.
Shared responsibility cannot become a shared excuse.
We Are Not Saying Stop Testing
Quite the opposite.
The CRD demonstrates exactly why long-term monitoring is valuable.
We need the baseline.
We need scientists.
We need laboratories.
We need to know whether conditions are improving or getting worse.
We need to know what is entering salmon habitat.
We need to know what is appearing in sediment and marine organisms.
We need to know what threatens human health.
What we are tired of is testing becoming the destination instead of the starting point.
Canada has studied Fraser contaminants.
British Columbia has studied Fraser contaminants.
Municipalities have studied stormwater.
Universities have studied stormwater.
Washington State has studied stormwater.
Scientists have studied the Fraser plume.
Scientists have studied Fraser sediment.
Scientists have studied hydrocarbons.
Scientists have studied PCBs.
Scientists have studied tire chemicals.
Scientists have studied salmon.
Scientists have studied killer whales.
Government has now even built an online system mapping estimated contaminant releases and environmental-quality exceedances within killer-whale and Chinook habitat. (Canada)
At some point the citizen reading all those reports is entitled to ask:
What got fixed?
That Is the Question Greater Vancouver Residents Should Start Asking
Not:
"Did the city commission another study?"
Ask whether the street is being kept clean enough that polluted sediment isn't simply waiting for the next rain.
Ask whether catch basins are actually being maintained.
Ask whether known industrial and heavy-traffic areas get more attention than quiet residential streets.
Ask whether garbage and plastics can be intercepted before they reach rivers.
Ask whether local stormwater results are publicly available.
Ask whether agencies are working together instead of sending concerns from one jurisdiction to another.
And when monitoring identifies a recurring pollution problem, ask the most important question of all:
Did anybody actually stop it?
You don't need to be a biologist to ask that.
You don't need an engineering degree.
You don't need to understand every chemical name in a laboratory report.
You are the taxpayer.
You are the person eating the fish.
You are the person whose children swim in these waters.
You are the person being told billions of dollars must be spent restoring salmon and recovering Southern Resident killer whales.
You have every right to ask whether government is also stopping pollution at its source.
Because Restoration Without Source Control Is Backwards
Consider how much money we spend restoring habitat.
Rebuilding streams.
Planting riparian vegetation.
Restoring estuaries.
Opening salmon passage.
Rehabilitating shorelines.
Restoring shellfish habitat.
Trying to rebuild Chinook populations.
Protecting Southern Resident killer whales.
All worthwhile.
But if contaminated runoff continues entering those restored environments, we are working backwards.
You don't mop the floor while the tap is still running.
You turn off the tap first.
That is source control.
The Fraser Is Not a Drainage Ditch
Greater Vancouver is fortunate to have one of the great rivers of the world running through its backyard.
The Fraser supports salmon.
It supports birds.
It supports First Nations cultures and fisheries.
It supports communities and businesses.
It feeds an estuary of international ecological significance.
And then it enters another extraordinary ecosystem — the Salish Sea.
Its influence reaches beyond Vancouver.
Scientists have physically tracked its sediment through the Gulf Islands. (EPA Nepis)
Researchers have identified Fraser contributions to contaminant loads in Strait of Georgia sediments. (PubMed)
Federal scientists are studying hundreds of contaminants in the Fraser–Chinook–Southern Resident system. (Canada)
Washington State has spent more than thirty years building stormwater controls on the other side of the same Salish Sea. (Washington State Department of Ecology)
And the CRD has spent decades building a stormwater-monitoring baseline on this side of the Strait that includes the Southern Gulf Islands. (Capital Regional District)
Greater Vancouver cannot credibly say we need another generation to understand the problem.
The Next Report We Want to Read Is the One That Says the Water Got Cleaner
Our work with the Pacific Salmon Foundation started by asking what municipalities were doing.
That work showed us good people, good projects and some genuine progress.
It also reinforced what our field experience had already taught us:
Good intentions don't stop pollution. Source control does.
We don't need perfection tomorrow.
We do need direction.
Keep the stormwater monitoring.
Improve it.
Make the data public.
Support the people doing good work.
Learn from the CRD.
Learn from Washington State.
Do the simple things that prevent pollution before chasing the expensive things required after contamination has already spread.
And give the public something better than another glossy report.
Give us cleaner creeks.
Cleaner Fraser water.
Cleaner sediment.
Healthier shellfish beds.
Healthier forage fish.
Healthier Chinook.
Healthier birds.
And a healthier food web for Southern Resident killer whales.
Because whether you live in Vancouver, Burnaby, Richmond, Surrey, Delta, Coquitlam, Maple Ridge, Pitt Meadows, Langley or farther up the Fraser, the water leaving your community does not disappear.
There is no away.
It goes downstream.
And somebody — human, salmon, shellfish, bird, sand lance or killer whale — lives downstream.
Monitoring tells us where the problem is.
Source control prevents it from becoming somebody else's problem.
After decades of research, the message should finally be simple enough for every Greater Vancouver resident to understand:
