Pah Removal, Fate And Transport In Stormwater Bioretention Systems Amended With Biochar And Fungi, Chelsea Mitchell
Pah Removal, Fate And Transport In Stormwater Bioretention Systems Amended With Biochar And Fungi, Chelsea Mitchell
Salish Sea Ecosystem Conference
Bioretention is a widely implemented form of Green Stormwater Infrastructure used to prevent the pollution of receiving waters by stormwater runoff. Polycyclic Aromatic Hydrocarbons (PAHs) are a family of organic contaminants which are ubiquitous in stormwater. Several PAHs are toxic to aquatic species. Little is known about the transport and fate of individual PAH compounds in bioretention systems. Even less is known about how amendments to standard bioretention formulations might optimize PAH treatment. We conducted a mesocosm-scale experiment to evaluate the removal of PAHs using four types of bioretention media. We used a standard, planted bioretention media mixture (60:40 sand:compost …
Bioretention For Lakes: Washington's Search To Replace Compost In Our Stormwater Filters, Dr. Dylan Ahearn
Bioretention For Lakes: Washington's Search To Replace Compost In Our Stormwater Filters, Dr. Dylan Ahearn
Salish Sea Ecosystem Conference
Bioretention is the most widely applicable and flexible stormwater treatment practice we have available today. The Washington State Department of Ecology (Ecology) specification for bioretention soil media (BSM) is a mixture of 60 percent sand and 40 percent compost (60/40). Washington is not alone by including compost in BSM; Massachusetts, Nebraska, Maryland, Colorado, the list goes on. While the 60/40 BSM can provide reliable water quality treatment for some contaminants, it has been shown to export high levels of nitrogen and phosphorus. We will present the journey that the state of Washington has taken over the last 6 years to …
Kulshan Carbon Trust Internship, Olivia Benolken
Kulshan Carbon Trust Internship, Olivia Benolken
College of the Environment Internship Reports
The Kulshan Carbon Trust is a Washington-based non-profit implementing collaborative natural climate solutions in Whatcom and Skagit Counties through landholder engagement, supply chain development, market incentives, and workforce training. The KCT aims to promote regenerative land use practices that reduce agriculture, forestry, and land development emissions and increase carbon sequestration by supporting regenerative agriculture, forest restoration, and biochar production in our community. KCT provides an organizational framework that puts people to work protecting existing carbon reserves and rebuilding carbon stockpiles in soils and plants to foster healthy ecosystems for future generations. As an intern for the KCT, my role was …

Kulshan Carbon Trust Regenerative Agriculture Business Intern, Jessica Espy
College of the Environment Internship Reports
The Kulshan Carbon Trust is a local Nonprofit organization. The KCT founders are Howard Sharfstein, Steve Hollenhorst, and Jessa Clark. KCTs mission “is to conserve and sequester carbon through collaborative natural climate solutions in Whatcom and Skagit Counties”. KCT plans to incorporate multiple Natural Climate Solutions to incentivize stakeholders to designate land for carbon sequestration. These Climate Solutions are “Forest Stewardship, Tree Planting & Growing, Biochar Supply, Regenerative Agriculture, and Blue Carbon (marine systems)”. The vision of KCT is “People working together to drawdown carbon in ways that regenerate the land and build prosperous communities”. Ultimately, KCT is interested in …

Kulshan Carbon Trust Internship, Cristal Borrelli
College of the Environment Internship Reports
KCT is a nonprofit organization that is based in Bellingham, WA and was officially founded in April of 2021. Their mission is to implement natural climate solutions through landholder engagement, market incentives and workforce training (KCT, 2021). This internship has allowed me to utilize my three years of environmental education, in a professional setting. On top of implementing my previous knowledge, I obtained more valuable information, experiences and skills that I will carry with me into my future career.
Soil Mesofauna And Microbial Community Response To Mixed Biochar And Compost Application In A Skagit Silt Loam, Jameson Goff
Soil Mesofauna And Microbial Community Response To Mixed Biochar And Compost Application In A Skagit Silt Loam, Jameson Goff
WWU Graduate School Collection
I sampled Skagit silt loam soils from a field trial at the WSU NWREC where biochar and compost were added to potato crops in late spring pre-planting. Soil mesofauna were sampled at mid and late-summer, while soil microbes were sampled at late summer exclusively. Soil treatments included mixed biochar and compost, compost-only, and an unamended control. Mesofauna were extracted with Berlese funnels and sorted to functional groups. F:B ratios and total microbial C were determined using microbiometer test kits. To test whether biochar and compost induced changes to soil mesofauna communities, I used permutational ANOVA. Differences in F:B ratios and …
