University of Saskatchewan Researcher awarded $2.5 million to optimize contaminated site remediation approaches

Over the last five years, University of Saskatchewan soil scientist and Industrial Research Chair (IRC) Steve Siciliano and his team have developed techniques that can reduce hydrocarbons in the soil by more than 90 per cent.  

Now, the Natural Sciences and Engineering Research Council (NSERC) and Federated Co-operatives Limited (FCL) are each providing $1.25 million to renew the five-year term to build on this success and further optimize soil remediation approaches. 

“The overall goal of this innovative research program is to improve how we clean up and manage these impacted sites in a safe and sustainable manner,” said Dr. Siciliano.

“Over the next five years, we will further develop and validate our approach of using naturally occurring biological stimulants and nutrients to further increase hydrocarbon degradation, particularly at sites where traditional approaches have proven ineffective, and reduce hydrocarbons in soil to minimal levels.”  

Canada has more than 30,000 sites contaminated with hydrocarbons or other pollutants. These sites pose significant social and economic costs to cities, towns, and villages.  

NSERC and FCL invested a combined $2 million during the IRC’s five-year first term (2015-2020). Researchers introduced environmentally friendly solutions to impacted soils to stimulate microbial populations that naturally break down petroleum molecules.  

The traditional method of cleanup involves excavating impacted soils and relocating them to a landfill or treatment site. Reducing contamination on site is safer, cheaper and more sustainable as the environment is not disturbed and existing business can continue without disruption. 

The research has proven to be successful and FCL has already applied the findings outside of the initial six locations, said FCL’s Vice-President of Strategy Pam SkotnitskyOur investment demonstrates our responsibility and commitment to the overall health and well-being of our communities. We continue to work together with our academic and industry partners to find innovative solutions that are openly shared and have long-term, widespread benefits.” 

IRCs are funded jointly by NSERC and industry and must be in an area of high priority for both the university and the industrial partner. The funding supports salaries for students and other research personnel, equipment and materials. 

“NSERC is proud to support research endeavours aimed at creating a better future for all Canadians,” said NSERC Vice-President (Research Partnerships) Marc Fortin. This renewed collaboration will support the development of new techniques to remove hydrocarbon pollution from the soil of contaminated sites, resulting in cleaner soils across our country. This research will allow Dr. Siciliano and his team to continue to be leaders in the field of soil remediation, and create positive impacts on our environment.” 

In addition to its share of the matched funding, FCL will provide $1.9 million of inkind support. USask in-kind contributions include $1 million. More than 50 USask undergraduate and graduate students will contribute to the research.

Assessing the Long-term Performance and Impacts of ISCO and ISBR Remediation Technologies

The Environmental Security Technology Certification Program (ESTCP), the U.S, Department of Defence’s environmental technology demonstration and validation program, recently issued a Fact Sheet that summarizes the results of a recent remediation project that assessed the long-term performance of in-situ chemical oxidation (ISCO) and fracturing-enhanced in-situ bioremediation (ISBR) at a site contaminated by trichloroethene (TCE), 1,4-dioxane (dioxane), and chromium.  The project was conducted at Air Force Plant 44, which is part of the Tucson International Airport Area federal Superfund site located in Tucson, Arizona.

The Arizona site comprises several primary source zones and a large, several kilometer long, groundwater contaminant plume that resides in the regional aquifer. The remedial action and performance monitoring were conducted by the Air Force contractor.

Performance monitoring data were obtained for a period of greater than three years after completion of ISBR. The project focused on treating the interface between the vadose zone and saturated zone. This interface region, which consists of primarily lower permeability (clay) media, has been identified as a primary location for remaining contaminant. Slow release of contaminant from this domain is considered a primary cause of the observed delayed attainment of cleanup objectives.

Key Result 1: ISBR employing enhanced reductive dechlorination (ERD) was effective.

TCE, chromium, and dioxane concentrations at site DP003 were reduced by 94, 83, and 36%, respectively. The observation of cis-1,2-dichloroethene, vinyl chloride, ethene, and ethane in groundwater samples after ISBR implementation (but not before) supports that reductive dechlorination of TCE was initiated in the treatment zone.

Key Result 2: ISBR employing enhanced aerobic cometabolism (EAC) was effective.

Dioxane and TCE concentrations at site DP003 were reduced by 92 and 60%, respectively. The concentrations of chromium remained essentially unchanged over the course of the EAC-ISBR treatment, which indicates that the generation of aerobic conditions had no measurable impact on chromium levels in groundwater.

Key Result 3: The performance results are consistent with other field tests.

A meta-analysis was recently reported of enhanced anaerobic bioremediation projects conducted for sites wherein the original contaminants of concern (COC) were either tetrachloroethene or TCE. The median concentration reduction was 90% for 34 sites for which the  erformance-monitoring period was at least three years. The %-reductions observed for the present study are consistent with the meta-data.

Key Result 4: The longer-term performance assessment provided more robust assessment.
Concentrations of the COCs measured after >3 years of monitoring were approximately 50% lower than the values measured after three months for a majority of the sampling points. This demonstrates the advantage of conducting longer-term performance assessments.

Update on the Remediation of Low-Level Radioactive Waste in Port Hope, Ontario

Canadian Nuclear Laboratories (CNL) recently announced that it has completed the excavation and transfer of historic low-level radioactive waste away from the Lake Ontario shoreline in Southeast Clarington.

The placement of the last truckloads of waste in the aboveground mound at the new long-term waste management facility, located about 700 metres north of the shoreline site, marks a milestone for the Port Granby community and the Port Hope Area Initiative (PHAI). CNL is implementing the PHAI on behalf of Atomic Energy of Canada Limited (AECL), a federal Crown corporation.

“The safe and successful completion of this remediation is the culmination of years of hard work and planning carried out by CNL’s Port Hope Area Initiative team, and fulfills a key commitment by the Government of Canada to restore these lands for the local community,” said Joe McBrearty, CNL President and CEO. “This milestone represents continued progress in one of the largest and most complex environmental clean-up missions ever undertaken in Canada.”

Remediation of the legacy waste management site began in 2016 and was undertaken in stages, with each section of the site undergoing a stringent testing process to confirm that all contaminated material had been removed. Verified areas were then backfilled with clean soil and restored by hydroseeding and planting vegetation. As the cleanup neared completion, internal roads and other infrastructure were removed.

Capping and closing of the engineered storage mound at the new facility is underway and expected to be completed in summer 2021, with final landscaping targeted for summer 2022.

Dedicated systems are being installed within the mound and around the perimeter of the new facility to closely monitor the safety and performance of the facility for hundreds of years into the future.

“I want to thank the residents of Port Granby for their support and patience during the decades of community consultation, followed by the remediation and restoration of land in the heart of their rural community,” said Richard Sexton, President and CEO of AECL. “I am very pleased that CNL and its contractors have fulfilled the Government of Canada’s commitment to clean up the lakefront site so generations to come will enjoy the benefits of a cleaner environment.”

ABOUT THE PORT GRANBY PROJECT
The Port Granby Project involves the relocation of approximately 1.3 million tonnes of historic low-level radioactive waste from the legacy storage site on the shoreline of Lake Ontario in Southeast Clarington, to a new, engineered aboveground mound. Ongoing maintenance and monitoring will continue for hundreds of years after the facility is capped and closed. The historic waste resulted from radium and uranium refining operations of the former Crown corporation Eldorado Nuclear and its private sector predecessors, which operated from the 1930s to 1988.

ABOUT THE PHAI
The Port Hope Area Initiative (PHAI) represents the federal government’s commitment to respond to the community-recommended solutions for the cleanup and local, long-term, safe management of historic low-level radioactive waste in the municipalities of Port Hope and Clarington. Through its Historic Waste Program Management Office (HWP MO), Canadian Nuclear Laboratories is implementing the PHAI on behalf of Atomic Energy of Canada Limited, a federal Crown corporation.

Chedoke Creek spill update: City of Hamilton receives additional Orders from Ministry of the Environment, Conservation & Parks

The City of Hamilton, Ontario recently received an additional Provincial Officer’s Order from the Ontario Ministry of the Environment, Conservation & Parks (MECP) as they relate to a spill into Chedoke Creek.

In 2019, the MECP ordered the City to complete an Environmental Risk Assessment of Chedoke Creek and an Ecological Risk Assessment for Cootes Paradise. These studies both found that it was not possible to attribute environmental impacts experienced in these areas exclusively to the spill.

The most recent Order from the Ontario Environment Ministry requests that the City undertake remedial action for Chedoke Creek and Cootes Paradise. In part, the Order asks that the City develop a plan for targeted dredging in Chedoke Creek and recommends mitigation measures to improve water quality in Cootes Paradise.

The City stated that it is committed to continuing its full cooperation with the MECP’s investigation and staff will be consulting with Council regarding how we can best address the environmental concerns in Chedoke Creek and Cootes Paradise.

To date, in response to the spill, the City has taken a number of actions toward addressing the impacts of the discharge, including:

  • Undertaking clean-up of the creek, including removing 242,000 litres of “floatable material” from the surface and edge of the creek.
  • Initiating regular monitoring of water quality in impacted areas of Chedoke Creek.
  • Initiating and implementing enhanced inspections of wastewater facilities and equipment.
  • Undertaking expert studies to determine what kind of further remediation is appropriate for Chedoke Creek and Cootes Paradise.
  • The approval of four new staff members to increase the City’s ability to perform regular, routine physical inspections and preventative maintenance for City water infrastructure, as well as sampling and analyzing water and wastewater quality in Hamilton.

Background Information

In July 2018, the City of Hamilton informed the public that it had discovered that one of its combined sewer overflow tanks was discharging untreated wastewater into Chedoke Creek. The City immediately stopped the discharge and began clean-up activities in the area.

Over the course of a four-and-a-half-year period, the City estimated that approximately 24 billion litres of combined storm water runoff and sanitary sewage was discharged into Chedoke Creek. This represents approximately four per cent of the annual volume of flow to Hamilton’s wastewater treatment plants.

Investigations have determined that the spill was the result of two separate malfunctions at the Main/King combined sewer overflow tank. First, a station bypass gate in the combined sewer overflow tank that should have been in a closed position appears to have been manually opened to approximately five per cent on January 28, 2014. An error in computer programming showed this as normal operation and, as such, this error remained undetected until July 2018. Additionally, a second gate that should have remained in the open position experienced a mechanical failure in January 2018. The sensor on this piece of equipment did not pick up the failure and was reporting normal operation. Despite extensive investigations, the City has not been able to determine why the first bypass gate had been opened in January 2014.

Update on Faro Mine Remediation Project

The Government of Canada recently announced it had reached a significant milestone in the Faro Mine Remediation Project that will help protect the valuable fish habitat of Rose Creek.  Under the North Fork of Rose Creek Realignment Project, clean water has started to flow through a newly constructed channel that will help prevent the contamination of Rose Creek. In collaboration with Yukon partners and First Nations communities affected by the contaminated site, the Government of Canada continues to work to ensure environmental protection work is maintained throughout the COVID-19 pandemic and beyond.

The Faro Mine in south-central Yukon was once the largest open pit lead-zinc mine in the world. Today, it is the site of one of the most complex abandoned mine remediation projects in Canada. While the full remediation plan to clean up the mine is under environmental assessment, certain necessary work like this project have continued at the site as they are critical and essential for protecting human health and safety and the environment.

Realigning this section of the creek has been vital for ensuring that clean water and valuable fish habitat in Rose Creek do not come into contact with the contaminated water from mine wastes. Contaminated water can now be captured for treatment on site while the clean water safely flows into a new channel that reconnects with Rose Creek. Fish overwintering ponds have also been built to compensate for fish habitat lost due to construction.

This project has been important for the environmental protection of the area and to local First Nations: Ross River Dena Council, Liard First Nation and Selkirk First Nation. Yukon-based company Pelly Construction Ltd. was awarded the subcontract for the realignment project and partnered with Ross River Dena Council’s Dena Nezziddi Development Corporation to include training and employment of local Indigenous workers for the project.

The Dena Nezziddi Development Corporation also actively participated in the construction of a new work camp at site. The camp provided temporary housing for approximately 75 workers who came from Ross River and other communities outside of Faro and the Yukon, reducing travel between Northern communities during the COVID-19 pandemic. To date, there have been no confirmed cases of COVID-19 at the mine site.

The North Fork of Rose Creek Realignment Project has been an important and necessary part of protecting the environment and in advancing one of the most complex abandoned mine remediation projects in Canada.

QUOTES

“I would like to extend my congratulations to the Faro Mine Remediation Project team, as well as their First Nations and Yukon partners, on the North Fork of Rose Creek Realignment Project. Canada has been working collaboratively with Northern and Indigenous partners, and we are proud to see opportunities for training, employment, and engagement with Yukon First Nations on this long-term project as a whole and on critical work for environmental protection. We know that by working in collaboration with all partners, we will be able to effectively continue to advance the long-term remediation plan while also managing the immediate risks to both the health of northerners and the environment.”

The Honourable Daniel Vandal, P.C., M.P.
Minister of Northern Affairs

“Remediating the Faro Mine Site is our top priority. The completion of the North Fork of Rose Creek realignment marks an important step towards protecting the water.

We want to see the remediation work continue and for this to remain a top priority for Canada and the Yukon.”

Chief Jack Caesar
Ross River Dena Council

“The Government of Yukon is pleased with the advanced progress on the North Fork Rose Creek realignment project. Our skilled Yukon-based workforce is why this project can continue despite limitations due to COVID-19. We are glad that Yukoners and Yukon First Nations will benefit economically from participation in these urgent works. It also proves that Yukoners are well positioned to contribute to remediation activities being implemented at Yukon’s abandoned mines.”

Minister Ranj Pillai
Energy, Mines and Resources, Government of Yukon

“The Faro Mine Remediation Project is key to supporting our communities, strengthening our economy, and protecting the environment. Yukoners and Yukon First Nations continue to be an important part of this remediation and the North Fork of Rose Creek Realignment Project. I am happy to see the remarkable progress made as work continues during this unprecedented time. It is a testament to the dedication of all those involved in the project.”

The Honourable Larry Bagnell, P.C., Member of Parliament for Yukon

Quick Facts

  • Most work packages and subcontracts at the Faro Mine site are structured to maximize opportunities for Indigenous businesses.
  • To ensure the Faro Mine Remediation Project is a success and that all partners work cooperatively, a Transition Agreement situating management of the Faro Mine Remediation Project under the Government of Canada has been signed by both Selkirk First Nation and Ross River Dena Council.
  • Budget 2019 allocated $2.2 billion over 15 years to create the Northern Abandoned Mine Reclamation Program, starting in 2020–21. The program will remediate the largest, most complex contaminated sites in the North.

Canadian Government Awards Contract for clean-up of KELSET Creek Pond, British Columbia

The Canadian government recently announced that it had awarded a contract to complete the second phase of the ḰEL¸SET (formerly Reay Creek) Remediation Project that will remove sediments with elevated levels of metals from this 200 metre long pond. Last summer, the first phase of creek sediment remediation was completed within the Victoria Airport boundary.

The pond clean-up work will begin this summer and is expected to be complete by fall 2020.  The remediation work will be restricted to a short window of time between the cutthroat trout and coho salmon’s critical spawning timeframe in the ḰEL¸SET (Reay) Creek.

The clean-up work involves diverting the creek around the pond area, excavating contaminated sediment in the pond, transporting the sediment to an approved facility for treatment/disposal, and backfilling the pond. It is estimated that approximately 3,900 cubic meters of sediment will be removed from the pond, which is about seven times more than the volume excavated during last year’s work.

The contract awarded to QM Environmental for $1,144,350 will be closely monitored by Transport Canada to ensure the safety of workers and the community. The work will be conducted in accordance with all federal and provincial guidelines, including those addressing COVID-19. Construction and environmental monitoring will be conducted throughout the project to ensure that clean-up activities comply with Town of Sidney bylaws and do not adversely impact the surrounding environment.

Reay Creek is also known by the Sencoten name ‘Kelset,’ (pronounced “KWAL-sit”). It is a relatively small creek originating both on the east side of the Victoria International Airport and the northeast slope of Mount Newton. It drains into Bazan Bay near Sidney.

A healthy waterway is essential for the well-being of fish who live there. Fish health is threatened when high concentrations of metals that don’t break down remain in the environment, threatening the marine food web.

The ḰEL¸SET (Reay) Creek Remediation Project is funded through Canada’s Federal Contaminated Sites Action Plan (FCSAP). FCSAP provides funding to assess and remediate federal contaminated sites and is coordinated by Environment and Climate Change Canada and the Treasury Board of Canada Secretariat.

Marc Garneau, the federal Minister of Transport stated, “Completing this phase of the ḰEL¸SET (Reay) Creek remediation project demonstrates our government’s commitment to remediating contaminated sites and protecting the environment. Cleaning-up the pond will reduce threats to the pond ecosystem and the food web, in addition to providing a healthier home for cutthroat trout and coho salmon.”

The initial phase of the remediation project, conducted in 2019, removed and treated 923 tonnes of contaminated sediment from portions of the creek bed located on the Victoria Airport.
