Stand up for a healthy coast—The Coastal Pollution Mapper

Killer whales and salmon are icons of the West Coast. These animals represent nature’s raw beauty and embody the Sea to Sky country by connecting mountains with ocean. It’s hard to imagine a world without them, but their survival in the Salish Sea is uncertain.

There are 78 remaining southern resident killer whales and these creatures have arguably the highest levels of toxic contamination of any species on the planet. This is a result of human impacts on their habitat. Salmon populations are also under stress and are migrating northward in response to a changing climate. Maintaining the current populations of these species in the Salish Sea requires thoughtful management of our impacts on their marine world.

We create a lot of pollution. Toxic chemicals like PCBs, hydrocarbons and pesticides have washed over the land, into rivers and out to the ocean where they enter the food web. Plastics have become a serious problem and microplastics, tiny pieces of degraded plastic, enter the food web just like chemicals. This pollution builds up along the coast and makes its way into shellfish, birds, fish, whales and even people. In high concentrations this causes sickness and death for some animals and turns healthy food into a health risk for people.

We’re supporting the people working hard to make our coasts healthier. A healthy coast means less pollution, sustainable land use practices, healthy animals and healthy people. You can help repair and protect our common environment by putting the right tools in the hands of the people working hard to clean up and maintain our shores.

Your support will allow the field validation and refinement of two tools for reducing the cost of pollution testing.

1)    An algorithm for predicting pollution concentrations throughout a site that combines data collected by drones with lab tested samples of soil and water showing the concentrations pollutants. This will allow pollution to be measured in greater detail with less samples taken, saving time and money.

2)    A new biosensor that will open up the possibility of low-cost in-field testing for initial assessment of pollutants. In some cases this can suit pollution monitoring needs on its own, and in others it can identify pollution hotspots and inform the selection of sample areas for further testing in the lab. 

In addition to supporting the advancement of these technologies and products, your support will directly contribute to the management of the Little Campbell river and estuary in Surrey, BC. It will support planning for the development of healthier salmon habitat (and by extension healthier food for killer whales). It will also provide crucial data that will help the Semiahmoo First Nation advance their goal of re-opening their shellfish fishery, closed since the 1970s due to contamination.
