Can a Saskatoon brownfield be transformed into fertile green space?

The City of Saskatoon, Saskatchewan is in the process of implementing a Brownfield Renewal Strategy that it deems essential to growth in its main corridors. The initiative aims to assess and prioritize redevelopment potential of abandoned, vacant, derelict, or underutilized properties along the City’s major corridors that may have or do have perceptions of contamination.

The results of the brownfields evaluation will lead to the formulation of an incentive program that will help overcome financial and environmental barriers for redevelopment, as well as provide contamination management plans for future development.

One recent brownfield development in Saskatoon was initiated by a not-for-profit organization called CHEP Good Food.  CHEP has been promoting food security in Saskatoon for nearly 30 years. The organization is currently working toward restoring a plot of contaminated land to an agricultural plot of land.

The non-profit group, which works to promote food security, has already won a grant from CN Rail that will help them plant native trees and bushes at another brownfield site in Saskatoon and to restore the soil.   The project received the CN EcoConnexions grant through Tree Canada / Arbres Canada and Canadian National Railway Company to plant native trees and shrubs on the site.

A previous fruit and vegetable garden project by CHEP began in 2014 under a different name as rooftop gardens at the University of Saskatchewan. The project relocated to the brownfield site  in 2015 and was renamed the Askîy Project — which means “Earth” in Cree.

The latest CHEP project is more ambitious than the existing Askîy Project.  It involves growing trees and bushes directly in the soil as well as remediation the site.  A professor from the University of Saskatchewan, Susan Kaminskyj, will oversee experimental bio-remediation at the site.

The bio-remediation will consist of utilizing native a fungi that will assist the plants in growing but will also biodegrade the petroleum hydrocarbon contamination at the brownfield site.

Professor Kaminskyj explained in an interview with CBC, that the microbe is a common fungus, but one with “unique abilities.”  A property in the fungus allowed plants to grow and thrive on coarse Oil Sands tailings.  In early field trials, Professor Kaminskyj’s team found more than 90 per cent of dandelion seeds treated with the fungus sprouted on coarse tailings while no untreated seeds sprouted. The researchers also found the fungus was able to grow with diesel, crude oil and similar materials as its only nutrient source.

 

 

 

Concern about Hazmat Incidents at Canada’s Proposed Spaceport

In a joint venture with several US firms, Halifax-based Maritime Launch Services (MLS) is building Canada’s first spaceport near Canso, Nova Scotia. At a total cost of $304 million—a figure that includes the cost of the first rocket launch and promotional expenses—the launch pad is slated to deliver commercial satellites to low Earth orbit aboard Ukrainian-built rockets on a due south trajectory, and at a cost of $60 million per launch.

The Canso Spaceport Facility will be 20 hectares in size and is aimed at attracting firms that want to put satellites into orbit for commercial purposes.  The site will include a control centre, launch area and “horizontal integration facility,” where materials will be prepared for the launch and some propellants will be stored

The company would like to launch as many as eight rockets per year starting in 2022.

There are concerns about the spaceport from government experts.  Specifically, concerns related to environmental and health & safety issues.  Recently released documents released by the province detail numerous questions about the planned Canso Spaceport Facility.  Nova Scotia’s environment ministry will not approve the project unless their concerns are addressed.

The specific concerns of the N.S. Environment Ministry is how the company will address an explosion, crash or fuel leak.  According to the recently released government document, a spill would “destroy the impacted ecosystems with no chance of recovery within the next several hundred years.”

According to the Maritime Launch Services proposal, the rockets would use nitrogen tetroxide and unsymmetrical dimenthyl hydrazine, or UDH, for the second portion of their launch into the atmosphere.

A letter from the Canadian Defence Department says the military “does not have sufficient knowledge” to assess the impacts of an accidental discharge of the UDH on the land or surface water, but “suggests an assessment should be completed.”

A professor at the University of British Columbia has raised concerns about an “exceedingly toxic” rocket propellant that will be used at the Canso, N.S., operation. Michael Byers, a political science professor at UBC, said there is a danger associated with UDH — which he said is known in Russia as “the Devil’s Breath.”

Professor Byers stated “If something goes wrong on launch, you know, if the rocket were to tip over and explode, or if there were some kind of spill during transportation or assembly, you’d still have a serious health and environmental concern.”

Other government officials comment that there isn’t enough information in the proposal to assess potential dangers.

Chuck McKenna, a manager with the resource management unit of the provincial Environment Department, says detailed plans on how dangerous goods will be stored and handled weren’t provided.

He says this should include details on the potential effects of a chemical accident, prevention methods and emergency response procedures.

Johnny McPherson, an expert on air quality in the provincial Environment Department, says in his submission that the first stage propellants of a rocket can create “black carbon (soot)” that is “harmful if inhaled because of small particle size and damaging effects.”

The government comments were made in response to the environmental assessment of the project prepared by a consultant.

Nova Scotia Environment Minister Margaret Miller said last week the environmental assessment, submitted in July, didn’t contain sufficient information for her to make a decision on whether to approve the project.

Miller has given the company one year to provide additional information and studies.

The company’s president has said he’s confident the firm will finish the study in response to the concerns raised, and it is “optimistic” it can address the issues raised.

competition to destroy chemical weapons launched by UK and US

The United Kingdom Defence and Security Accelerator (DASA), part of the Defence Science and Technology Laboratory (Dstl) and UK Ministry of Defence (MOD), has launched the ‘Don’t Blow It!’ competition, the first joint UK-US industry competition run by DASA and funded by the MOD and US Department of Defense (US DOD).

Competitors have been asked to identify innovative concepts or adapt current technologies to access, disable and destroy chemical and biological devices. This includes chemical and biological munitions, improvised explosive devices containing lethal agents or containers of bulk quantities of chemical or biological agents discovered on the battlefield or in other austere and resource-limited environments.

Defence Minister Stuart Andrew said:

Horrific incidents stretching from Salisbury to Syria this year have shown us that chemical weapons are sadly still very much a reality – but a reality that we are determined to deal with. Destroying these deadly weapons is a complicated process and not doing it properly could mean devastating collateral damage. These are challenges that we share with our allies like the US. Competitions like this help us to tackle them head on with some of the best and brightest minds across both our countries.

Although it is over 100 years since the first large-scale use of chemical weapons, the threat from both chemical and biological weapons persists. This has been demonstrated by the recent rise in the use of such deadly weapons on the battlefield and in targeted attacks.

Much progress has been made to destroy state-declared global stockpiles of chemical weapons through very successful large scale destruction programmes, utilising techniques such as incineration, explosive destruction or neutralisation. However, to meet emerging and future challenges, such as the destruction of smaller caches produced by terrorists in resource-limited or hostile environments such as Iraq or Syria, there needs to be a focus on developing more robust elimination capabilities that are less labour intensive.

The competition has an initial £500,000 to fund multiple proof-of-concept proposals at low Technology Readiness Levels. Additional funding of £1.5 million is anticipated to be available for future phases.

The competition is seeking innovative ideas from non-traditional supply sectors and is looking for ‘outside-the-box’ proposals that will:

  • enable rapid and flexible destruction
  • reduce logistical support requirements
  • maximise ease of operation and transportability
  • address a greater breadth of threats

MOD Chief Scientific Advisor, Dr Simon Cholerton said:

As the use of chemical weapons in Syria and the Novichok attack in Salisbury demonstrate, the risk from chemical weapons still remains and the issue of safely eliminating them from an austere tactical environment remains an enduring technical challenge. I am delighted therefore that we are working with our closest ally to launch a new industry competition to help us develop effective and safe elimination capabilities. Our collaboration is the first time we have launched a truly joint UK-US competition through the UK Ministry of Defence’s Defence and Security Accelerator, which is charged with enabling us to innovate by rapidly transforming the ideas of today into the capabilities of tomorrow.

Assistant Secretary of Defense for Nuclear, Chemical and Biological Defense Programs, US DOD, The Hon. Guy Roberts said:

The expanding proliferation of chemical weapons use, from state and non-state actors, portends the greatest threat of their use on the battlefield since World War I. My responsibility is to ensure our forces are protected from, and can fight through, any such threats. To that end, we must continually innovate our capabilities, and it is especially important to do so in collaboration with those who fight alongside us. This competition does just that. It allows us to jointly invest in research and development with our closest ally as well as seek innovative ideas from a broader set of brilliant minds who I am confident will lead us to creative solutions.

The competition was launched at an event in London on the afternoon of 26 September 2018. Potential suppliers were provided with context on the challenge by both UK and US speakers, as well as information on how to apply to the competition by DASA.

The submission deadline for proposals is 5 pm GMT (midday EST) on 7 November 2018.

New Technology for Mapping DNAPL Contamination

Laser-induced fluorescence (LIF)

As reported in Groundwater Monitoring and Remediation (38(3):28-42), DyeLIF™ is a new version of laser-induced fluorescence (LIF) for high-resolution 3D mapping of NAPLs in the subsurface.   DyeLIF eliminates the requirement that the NAPL contains native fluorophores (such as those that occur in compounds like PAHs) and therefore can be used to detect chlorinated solvents and other nonfluorescing compounds.

NAPLs were previously undetectable with conventional LIF tools. With DyeLIF, an aqueous solution of water and nontoxic hydrophobic dye is continuously injected ahead of the sapphire detection window while the LIF probe is being advanced in the subsurface.  If soil containing NAPL is penetrated, the injected dye solvates into the NAPL within a few milliseconds, creating strong fluorescence that is transmitted via fiber-optic filaments to aboveground optical sensors. This paper describes a detailed field evaluation of the novel DyeLIF technology performed at a contaminated industrial site in Lowell, Mass., where chlorinated solvent DNAPL persists below the water table in sandy sediments..

The DyeLIF system was field tested at a Formerly Used Defense (FUD) facility in Massachusetts in Fall 2013 (Geoprobe® delivery) and again in March 2014 (CPT delivery). The primary field demonstration completed in 2013 included two components: one week of DyeLIF probing and a second week of follow-on soil coring using research-quality direct push (DP) soil coring methods in order to compare DyeLIF results to colorimetric dye shake tests and laboratory analysis.

Several performance objectives were established in the project demonstration work plan and all were met or exceeded. The performance objective for chemical analysis was 70% consistency between positive DyeLIF responses and samples when DNAPL saturations were greater than 5%. The demonstration results showed 100% consistency between chemical analysis and DyeLIF for saturations greater than 1.9% (35 of 35 samples), and 95% consistency for estimated saturations greater than 0.5% (40 of 42 samples).

ESTCP funded Project ER-201121 to demonstrate the DyeLIF technology.  Additional details on the technology can be found at the U.S. Department of Defence Strategic Environmental Research and Development Program (SERDP) and the U.S. Department of Defence Environmental Security Technology Certification Program (ESTCP) link at SERDP-ESTCP.

Innovation in Detecting Oil Spills at Sea

The company ISPAS AS, headquartered in Norway, recently announced that it has developed a Ku-band polarimetric Oil Spill Detection (OSD) radar that can detect oil spills at sea and the open water under most conditions including dead calm.

The radar is specifically developed for this purpose and uses a higher frequency than typical navigational X-band radars.  The radar has electrically steered antennas with both electromagnetic polarizations and can map an oil spill continuously using the steerable antenna.

Radar image (left) of the oil spill (seen on right).

ISPAS has completed the installation of 4 new OSD radars.  The radars small size and weight makes it easy to integrate without large structural foundations.

ISPAS participated in the 2018 “Oil on water” exercise offshore of Norway recently with a small version of the polarimetric Ku-band OSD radar. The small radar performed exceptionally well. An example showing the real time display of radar measurements of oil on seawater onboard a vessel is presented in this picture. The picture to the right presents the actual view of the sea.

New Technology on Track to Vitalize Confined Space HazMat Training

by Steven Pike , Argon Electronics

Teams operating in confined spaces within hazardous industrial buildings or process facilities understand all too well the importance of adhering to strict health and safety regulations.

The hazards that confined spaces present can be physical or atmospheric in nature – from the risks of asphyxiation or entrapment to exposure to extremes of temperature or the release of toxic chemicals.

Confined Space Entry

According to the Census of Fatal Occupational Injuries, on average two people die in the US every day as the result of incidents that take place within confined spaces.

In many cases too, it is not just the victim who is at risk, but the rescuer or first responder who may be unaware of the hazard they are about to encounter.

Directives such as the Occupational Safety and Health Administration (OSHA), the Control of Major Accident Hazards Regulations (COMAH), the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR), Atex and many others all have a pivotal role to play in ensuring safety.

But despite the emphasis on prevention, any potentially harmful chemical release, and specifically one that occurs within the context of a confined space, will require personnel who are skilled and confident to handle a variety of complex challenges.

With these challenges in mind, a new app-based multigas simulator technology, specifically designed for use in confined space settings, is scheduled for release in late summer 2018.

And the new system looks set to deliver an enhanced level of realism for industrial HazMat training scenarios.

Applying CWA Technology to Industrial HazMat Training

The use of simulation technology for chemical warfare agent (CWA) training is already well established, with intelligent, computer-based training aids such as Argon Electronics’ PlumeSIM and PlumeSIM-SMART systems currently in use by military forces around the world.

The launch of PlumeSIM in 2008 provided CWA and CBRN instructors with a simulation package that enabled them to use their laptops, in conjunction with a map or images, to plan a diverse range of field and table-top exercises.

The type of substance, whether a single or multiple source and an array of environmental conditions (such as wind direction and speed) could all be easily configured. And the innovative technology enabled whole exercises to be recorded for after action review (AAR) and future contingency planning.

In 2016 came the introduction of PlumeSIM-SMART – which offered similar capabilities to PlumeSIM but replaced the use of simulator devices in the field with the simplicity of a mobile phone.

The ability to transform a mobile phone into a look-alike gas detector was to prove especially practical (and budget-friendly) for high-hazard industrial organizations and municipal responders.

And using mobiles offered some additional and unexpected benefits in that it enabled field exercises to take place in any location.

Realistic Multigas Training

The newest addition to Argon’s simulation technology portfolio has been devised for specific use within the training environs of confined spaces and multi-level buildings.

The device will offer HazMat instructors the flexibility to simulate specific levels and concentrations of gases, whether these be in the form of a gas escape or a dangerous device (or devices) concealed within a building.

It will also be highly configurable to enable instructors to select the use of either single or multigas sensors within their training scenarios.

The hardware will be identical to that currently available for CWA training and toxic industrial response training. It has also been configured to interact with existing hand-held gas detection simulators, such as PlumeSIM-SMART, to provide an enhanced level of realism and a more focused training experience.

Simulation sources will be able to be set to emit a signal that replicates the conditions of a particular substance, a low level or oxygen or an explosive atmosphere.

And as students move around the training environment, their display readings will adjust accordingly to simulate an event such as a breached alarm.

The latest detector also promises to overcome the issues posed by communications interference within buildings where GPS technology can often be limited.

Working in confined spaces within industrial complexes can present a daunting array of hazards, both for the staff operating within the facilities and for the emergency teams charged with first response.

The continued development of simulator technology can help to address these challenges by providing realistic, hands-on training opportunities that replicate real-life conditions.

Are there Greenhouse Gas Emission Savings in Hazmat or Remediation Projects?

Up to $575,000 in support available for winners of contest held on Massachusetts Institute of Technology’s Climate CoLab platform

The Centre of Social Innovation in Toronto recently launched a contest to solicit a broad range of possible solutions to help small to medium enterprises (SMEs) in Ontario reduce their direct and indirect greenhouse gas (GHG) emissions.  The winning proposals will be eligible to receive funding and support to pilot their solutions in Ontario over eight months.

In-situ remedation may generated GHG credits vs. dig-and-dump

The contest, now sourcing proposals on the Massachusetts Institute of Technology’s (MIT’s) Climate CoLab platform, allows members of the public to provide feedback to proposal authors, and to cast votes for the People’s Choice Winner.  A panel of judges will select 3-5 winning proposals based on their desirability, feasibility, scalability and impact to potentially be piloted in Ontario.

SMEs make up 98.2% of businesses in Canada, and emit as much climate change-causing greenhouse gas (GHG) emissions per year as Canada’s combined transportation sector, including every car, truck, train, plane, and ship. Reducing their emissions can benefit SMEs by helping them grow while also building healthier communities.

“Recent research from the University of Waterloo shows us that the vast majority of SMEs believe that sustainability is important,” said Barnabe Geis, Director of Programs at the Centre for Social Innovation. “We want to support the implementation of solutions – whether technologies, programs or services – that help SMEs meet their sustainability goals as a powerful way to both strengthen our economy and improve the health and well-being of our communities.”

Barnabe Geis,
Director of Programs, Centre for Social Innovations – Toronto

Many SMEs face barriers to lowering their emissions, from lacking the technical expertise to assess options for reducing emissions to not being able to afford the upfront costs of a low-carbon technology. However, once the right technologies or practices are implemented, the savings and other benefits to SMEs can be substantial. This contest will offer support to demonstrate the value and scalability of solutions in order to make the path towards sustainability more accessible to SMEs across the province.

There may be opportunities in the hazmat and remediation sectors to reduce the generation of GHGs from SMEs.  If so, the contest offers a great chance to secure third-party funding to pursue the opportunities.

The contest is open to proposal submissions until August 3, 2018. Proposals submitted prior to July 11th, will be reviewed by the Judges and given feedback before the contest deadline.

Oil Spill Response using Real Time Tracking and GIS Technology

A new project taking place of the coastline of St. John’s Newfoundland aims to reshape marine oil spill response through real-time tracking and GIS technology.

Integrated Informatics Inc., headquartered in Houston,Texas, recently received funding from the Newfoundland and Labrador Innovation Council to undertake a project that will aim to reshape the way in which asset and personnel tracking are handled for Marine Oil Spill Response in Newfoundland and Labrador.

In November 2008, the Odyssey, a British-owned oil tanker, broke in two, caught fire and sank in heavy seas about 900 miles east of Newfoundland, spilling about a million barrels of oil.

The project will include the development of a new Tracking Data Management System to be deployed to Marine Emergency Response Industry users.

A spokesperson for Integrated Informatics, Sharon Janes, stated in a press release, “It is not uncommon to still see paper maps and documents heavily relied upon in Emergency Response Plans.  The problem with these resources is that they do not present information that is as complete and current as possible within an emergency situation. This is what we are excited to help change – putting this data into the hands of responders as quickly and efficiently as possible.”

The Tracking Data Management System will be completed by August 2019, consisting of a suite of applications for asset and personnel tracking and a data management system to streamline the acquisition of data necessary for emergency preparedness exercises and active response within command centers.  These products will utilize Geographic Information System (GIS) technology – including rich mobile and web interfaces – as well as a robust data analytics and reporting dashboard.

Ms. Janes also stated, “By accessing asset and personnel tracking data through mobile devices and the web, first responders will be able to more efficiently interpret data, analyze trends, and plan response in real-time. Because this system rests on such a familiar platform [mobile, web], those with technical and non-technical backgrounds alike will be able to implement it into their workflows with ease.”

The planned system is one that has long been of interest within the Emergency Response and Natural Resources sectors of the Province – especially as organizations explore new, more challenging environments alongside their own endeavors to align processes and practices with innovative digital technologies.

Integrated Informatics Inc. is a consultancy for Geographic Information System implementation and development. Founded in 2002, Integrated Informatics has offices in Calgary, Alberta, Houston, Texas, and St. John’s, Newfoundland.
