Researchers develop sponge for recovering oil from wastewater

Researchers at the University at Imperial College London and the University of Toronto have developed a cost-effective sponge that can soak up oil relatively fast (less than 10 minutes). The research article, found in the Journal Nature, describes an innovative surface-engineered sponge (SEnS) that synergistically combines surface chemistry, charge and roughness.  The sponge is adept at adsorbing crude oil microdroplets.

The team of chemical engineers led by Pavani Cherukupally sought to find a solution by turning to polyurethane foam, a common material used in everyday household items like mattresses. Although polyurethane foam has good oil absorption properties, it only works well under certain conditions of acidity, which can strengthen or weaken the affinity between oil droplets and the sponge.

“It’s all about strategically selecting the characteristics of the pores and their surfaces. Commercial sponges already have tiny pores to capture tiny droplets. Polyurethane sponges are made from petrochemicals, so they have already had chemical groups which make them good at capturing droplets,” said Cherukupally.  “The problem was that we had fewer chemical groups than what was needed to capture all the droplets.”

The researchers developed a coating that alters the foam’s texture, chemistry, and charge, thus making it more suitable for a broad range of situations. When viewed under a microscope, the coating contains hair-like particles of nanocrystalline silicon that act like fishing rods for the oil droplets.

“The critical surface energy concept comes from the world of biofouling research—trying to prevent microorganisms and creatures like barnacles from attaching to surfaces like ship hulls,” Dr. Cherukupally said in a statement.  “Normally, you want to keep critical surface energy in a certain range to prevent attachment, but in our case, we manipulated it to get droplets to cling on tight.”

The sponge can remove microdroplets of crude oil in less than 10 minutes.  An earlier version of the sponge the the research team developed was able to remove over 95% of the oil in the tested samples, but it took three hours to achieve to same level of removal.

When tested under four different scenarios of acidity, the coated foam soaked up between 95% and 99% of the oil in approximately 10 minutes.  One of the great aspects of the sponge is that it can be reused after being washed with a solvent to remove the oil.  The oil can be recycled.

University of Saskatchewan Professor provides insight on oil spill remediation

A December 9th train derailment near the near Guernsey, Saskatchewan resulted in a spill of an estimated 1.5 million litres of crude oil.  According to Canadian Pacific Railway, it will take a number of weeks to clean up the spill.  The  Canadian Transportation Safety Board stated that 33 oil tank cars and one hopper car derailed.  Guernsey is approximately 115 kilometres southeast of Saskatoon.

In an interview with Global News, soil science professor Steven Siciliano noted details about how fast oil was spilling out of tank cars could make a difference.  “If it’s slowly seeping, what happens is you can kind of imagine a sort of pancakes, so then it doesn’t go as deep. Whereas if it’s rapidly spilling, it can actually get deeper into the soil. And the deeper in the soil it gets, the harder and harder it can get to remediate,” said the professor in the interview.  He added the Prairies have glacial till soil, which means it is made up of large clay layers which make it hard for water and air to go through them and making clearing oil very difficult.

Prof. Steve Siciliano, U of  Saskatchewan

Professor Siciliano is the NSERC/FCL Industrial Research Chair in In Situ Remediation and Risk Assessment Director, CREATE Human and Ecological Risk Assessment Program at the University of Saskatchewan.  Current and recent research projects undertaken by Professor Siciliano include modelling and assessing the transfer of pollutants from soil to children, development of new soil toxicity test methods and approaches for Antarctic and the Arctic, and assessment of cardiovascular effects of metals and polycyclic aromatic hydrocarbons.

Siciliano added many regions don’t have soil that freezes, which means techniques used in other areas won’t be as successful at the derailment site. He said many technologies have been developed in places like Oklahoma, California and southern Ontario, but the soil in Western Canada is much different from those places.

In a 2017 article in the Conversation, Professor Siciliano provided insight into various methods for managing oil spills including in-situ remediation.  In the article he provides estimates for “dig-and-dump” versus in-situ remediation.  He estimated dig-and-dump costing $150 per cubic yard of soil or more ($300 per cubic yard) in remote areas whereas the pricetag for in situ remediation can be as little as $20 to $80 per cubic yard.

Concern over potential slow response time at Burnaby crude oil storage facility

A recently disclosed fire protection audit report on the Burnaby, British Columbia crude oil storage terminal has raised concerns of local politicians and residents.  The facility is owned by TransMountain Pipeline.  The report estimates that the planned response time to a major event, such as a serious spill or fire, at six hours.

The Burnaby storage terminal is the end point of the Trans Mountain Pipeline System. It is a distribution point for crude oil and refined products to local terminals – the Parkland refinery and the Westridge Marine Terminal. The Burnaby terminal currently has 13 tanks with a combined storage capacity of 1.6-m bbl with secondary and tertiary containment.

The fire protection audit was commissioned by the National Energy Board (now the Canadian Energy Regulator [CER]) in 2016.  The audit was conducted by PLC Fire Safety Solutions, a company provide quality fire safety engineering services.

In May, the National Energy Board (now the CER) issued a report on Trans Mountain’s fire preparedness at three oil terminals in Burnaby, B.C., and Edmonton, Alberta. The CER report notes that TransMountain’s response time goal for assembling staff and contractors to initiate the fire fighting activities as six hours.  In its report, it states the TransMountain reduce the response time to four hours.

The PLC Safety Solutions report on the Burnaby terminal concluded in the emergency response plans were generally in compliance, but it raised questions about the time and manner in which the company’s own firefighting team could respond.

“Since there is currently no mutual aid agreement with the Burnaby Fire Department, initial response will be limited and response time could be six hours,” concludes the report.

The fire protection audit report was recently made public after the local Member of Parliament filed a Freedom of Information request.  In response to the report being made public and the  Since the report was prepared, the Canadian Energy Regulator has stated that the response time has been reduced to four hours.

TransMountain Pipeline issued a news release in response to the report’s finding being made public, stating, “At our terminals, we are ready to respond immediately with people and equipment. Trans Mountain has mutual aid agreements in place with other industrial operators in the areas where we operate, and contracts with response companies to provide fire responders to the terminals.”

The Burnaby crude oil storage terminal has been in operation for more than 65 years.  There has never been a storage tank fire.

 

Record $2.7 million fine for company causing oil spill in B.C.

Kirby Offshore Marine Operating LLC was recently sentenced in the Provincial Court of British Columbia, in Bella Bella, after pleading guilty to three charges of violating federal legislation, in connection with an October 13, 2016, spill from the vessel Nathan E. Stewart into Seaforth Channel near Bella Bella, British Columbia.

The company was sentenced to pay the following penalties:

  • $2.7 million for the offence of depositing a deleterious substance into water frequented by fish, in violation of the Fisheries Act;
  • $200,000 for the offence of depositing a substance harmful to migratory birds, in violation of the Migratory Birds Convention Act1994; and
  • $5,000 for the offence of failing to comply with the pilotage requirements under the Pilotage Act.

The $2.7 million penalty imposed under the Fisheries Act is the largest fine for the deposit of a deleterious substance into water frequented by fish from a single spill. This penalty will be directed to the Government of Canada’s Environmental Damages Fund and is recommended to be used toward the conservation of fish and fish habitat in the Central Coast region of British Columbia. The $200,000 penalty for the offence under the Migratory Birds Convention Act1994 will also be directed to the Fund.

On October 13, 2016, the tug boat Nathan E. Stewart ran aground at Edge Reef near Bella Bella, British Columbia, resulting in the release of approximately 107,552 litres (28,412 gallons) of diesel fuel and 2,240 litres (591 gallons) of lubricants. Both substances are deleterious to fish and migratory birds. Kirby Offshore Marine Operating LLC owned the Nathan E. Stewart.

The articulated tug-barge combo was on its way back to Vancouver from Alaska at the time of the incident. The fuel barge was empty, but the tug quickly began leaking diesel into the water. Seven crew members were on board, but no one was injured.

Kirby Offshore Marine is the largest United States operator of coastal tank barges and towing vessels participating in the regional distribution of refined petroleum products, black oil, and petrochemicals. Kirby’s coastal fleet operates along the U.S. coastal network and calls on ports along the Atlantic, Gulf and Pacific coasts, as well as ports in Alaska, Hawaii and on the Great Lakes.

As a result of the federal conviction, the company’s name will be added to the Environmental Offenders Registry.

UBC fined $1.2 million for Release of Ammonia-laden Water

The University of British Columbia and CIMCO Refrigeration were recently sentenced for offences committed in violation of the Canadian Fisheries Act, related to a 2014 ammonia-laden water release that ended up in a tributary of the Fraser River.

CIMCO Refrigeration was fined $800,000 after pleading guilty to depositing or permitting the deposit of a deleterious substance into an area that may enter water frequented by fish.

The University of British Columbia was fined $1.2 million after being found guilty of the several offences including the depositing or permitting the deposit of a deleterious substance into water frequented by fish (Booming Ground Creek) and failing to report the incident in a timely manner.

In addition to the fine, the University was also ordered to conduct five years of electronic monitoring of storm-water quality at the outfall where the release occurred.

The University has filed an appeal against these convictions.

Background on the Incident

On September 12, 2014, Environment and Climate Change Canada was contacted regarding an ammonia odour at an outfall ditch connected to Booming Ground Creek in Pacific Spirit Regional Park. The source of ammonia was identified as coming from a refrigeration plant at Thunderbird Arena at the University of British Columbia.

CIMCO Refrigeration and the University were completing repairs of the refrigeration system and used a negative pressure device, known as a Venturi, to purge residual ammonia vapours from the system. The mixture of water and ammonia was then discharged into a storm drain at the arena, which flowed to the outfall, through a ditch, and into Booming Ground Creek, which is a tributary of the Fraser River.

Officers and park rangers found approximately 70 dead fish in Booming Ground Creek in the two days following the discharge. The level of ammonia deposited in the water in the storm drain and ditch was analyzed and found to be harmful to fish.

As a result of this conviction, both organizations’ names will be added to the Environmental Offender’s Registry.

Researchers to study Arctic Spill Response and Clean-up

Researchers from Dalhousie University recently received $523,000 in Canadian federal government funding to investigate strategies to better separate oil from water and examine the risk of spills in the Canadian Arctic Archipeligo.

As climate change accelerates the melting of sea ice in the Arctic, the Northwest Passage could become a significant route between the Pacific and North Atlantic oceans. With the potential of increased Arctic vessel traffic, the Government of Canada is investing in science and research to ensure that we are prepared in an event of a spill.  

One research project funded under this program will test new methods to remove oil from water for greater efficiency during a cleanup. The other project will use advanced technology to help responders locate and identify spills, while minimizing harm to the marine environment. This new science and data will be important to inform decision makers and will help accelerate efficient decision making capacity. 

The two researchers that will be heading the investigation are Dr. Haibo Niu, and Dr. Lei Liu.

Dr. Niu currently works at the Department of Engineering, Dalhousie University. Haibo does research in Civil Engineering, Environmental Engineering and Ocean Engineering. His most recent research paper is entitled A Comprehensive System for Simulating Oil Spill Trajectory and Behaviour in Subsurface and Surface Water Environments.

For the Arctic research project, Dr. Niu is trying to develop a computer model that will predict the movement of an oil spill so responders know where it’s going and what it threatens.

Dr. Liu’s major research interests include coupled simulation-optimization modeling for groundwater management, site remediation system design, modeling of air/water/waste pollution control systems, and environmental risk assessment. He also has exposure to areas of regional environmental systems planning and management, climate-change impact assessment and adaptation planning, GIS and its application to environmental information systems, system dynamics, and uncertainty analysis.

The federal government is funding Dr. Liu’s project that will involve trying to find a way to use existing membrane technology to filter oil from oily waste water collected on board vessels during a spill cleanup. The goal is to create a unit carried on board to remove oil, allowing clean water to be discharged at sea rather than carried back to shore for treatment.

The projects are funded under the $45.5 million Multi-Partner Research Initiative, which aims provide the best scientific advice to respond to spills in Canadian waters. The initiative connects leading researchers both in Canada and around the world. These efforts will improve our knowledge of how spills behave, how to contain them and clean them up, and how to minimize their environmental impacts.

New Brunswick Marine Research Centre to study impact on spill clean-up chemicals on aquatic life

The Canadian Ministry of Fisheries, Oceans and the Canadian Coast Guard recently announced that it is investing $2.4 million in scientific research at the Huntsman Marine Science Centre in New Brunswick.

With this investment, the Centre will study how spill response measures, such as the use of dispersant chemicals, affect fish and other aquatic species of interest. The goal of the project is to ensure the use of effective response measures, without harming ocean life in the event of a spill.

The Huntsman Marine Science Centre is located in St. Andrews, New Brunswick. The Centre is engaged in a broad range of marine science and applied research initiatives.

Canada to Commits Major Funding to Scientific Research on Oil Spill Response

The Government of Canada recently announced that it was committing $4.1 million to six international organizations to fund research projects that will help improve protocols and decision-making to minimize the environmental impacts of oil spills.

The recipients include: Commonwealth Scientific and Industrial Research Organisation; Johns Hopkins University; New Jersey Institute of Technology; SINTEF Ocean; Texas A&M University; and Woods Hole Oceanographic Institution.

Examples of the projects that will be founded included the following:

  • The Woods Hole Oceanographic Institution in Woods Hole, Massachusetts is receiving $638,000 to conduct a three-year study to quantify the effect of oil photochemical oxidation on the performance of chemical herders in Canadian waters; and
  • Johns Hopkins University in Baltimore, Maryland is receiving $760,000 to conduct a four-year study on the effects of crude oil properties, dispersants, and weathering on the breakup of plumes and slicks.

These projects are part of the $45.5 million Multi-Partner Research Initiative, announced last year to leverage collaboration among oil spill experts in Canada and abroad to ensure we have the capability to provide the best scientific advice and tools to respond to oil spills in our waters.

A total of 35 Canadian and international projects will focus on a wide range of innovative strategies and technologies to aid in oil spill response. Under this initiative, researchers will investigate computer modeling to predict the movement and fate of spilled oil, the use of chemical dispersants and herders, the efficiency of in-situ (or onsite) burning of oil spilled at sea and the potential of bio-based agents to disperse oil through biodegradation.

The Multi-Partner Research Initiative will support a variety of different but interrelated research projects on alternative response measures for oil spills while facilitating partnerships among the best researchers across Canada and around the world. These collaborative efforts will improve our knowledge of how oil spills behave, how best to contain them and clean them up, and how to minimize their environmental impacts.

Leaking Sewers Cost City 50% of Dry Cleaner Site Cleanup Costs

Written by John A. McKinney Jr., Chiesa Shahinian & Giantomasi PC

Are you in a case where an on-site and off-site groundwater plume of dry-cleaning solution (perchloroethylene or PCE) or other hazardous substance is intersected by sewers through which the used and disposed solution flowed?  If so, the case of Mission Linen Supply v. City of Visalia (2019 WL 446358) bears your close review.

Based on the facts and expert testimony adduced at the bench trial, the court determined that: 1) the sewers were installed by the City were below general industry standards which can be better understood if you talked to a professional similar to a pipe lining company in San Diego; 2) the City sewers had numerous defects including holes and broken pipes, cracks, separated joints, missing portions of pipes, root intrusion and other conditions; and, 3) PCE was released into the environment as a result of these defects.

Pursuant to the Comprehensive Environmental Response, Compensation and Liability Act (42 U.S.C. § 9601 et seq.), the two dry cleaners who operated at the site and the City were found liable.  In allocating the future cleanup costs, the court determined the equitable basis for allocation was the plume itself.  The prior dry cleaners were responsible for the on-site costs and the City was responsible for the off-site costs “because the City’s defective/leaking pipes transported and spread the PCE beyond the property boundaries.”   50% of future costs were assigned to the City.

A review of this case’s Findings of Fact show what expert testimony and evidence is necessary to reach the result reached by this court.  The case is also a warning to municipalities with sewer lines intersecting cleanup sites or what could become cleanup sites.  Do not fail to regularly and properly maintain your sewer systems.
