Soil Treatment and Disposal for contaminated soil including Special Waste at the Abbotsford and Burnaby facilities. Sumas also operates temporary bio-cell in several municipal landfills in Western Canada for the treatment of hydrocarbon contaminated soil.

Hazardous and Industrial Wastes Treatment and Disposal including solids, sludges and contaminated water at the Burnaby and Alberta facilities.

Industrial Services, Equipment Rental, and Emergency Response includes confined space entry and industrial tank and equipment cleaning, wastewater treatment equipment rental, and the dispatch of trained emergency response personnel and Sumas owned equipment such as pumps, loaders, excavators, and vacuum truck to the site of the spill.

The Burnaby facility is permitted by B.C. MoE for handling various hazardous wastes through incineration, stabilization and bioremediation. These include TDG Classes 2 to 9, hydrocarbon contaminated soil, water and waste oil.

The Edmonton facility is a hazardous waste transfer station permitted by Alberta Environmental Protection for all classes of hazardous wastes.

The Big Valley facility can handle all types of heavily contaminated solids and sludges such as oilfield waste filters and tank bottoms.

Sumas maintains a highly trained workforce and has extensive experience in dealing with a wide variety of chemicals. Our mandatory training for all personnel includes WHMIS, TDGR and personal protection equipment (PPE). Select personnel are also trained in OSHA and emergency first aid response. This commitment to staff training has earned us an impeccable safety record.

Sumas Environmental provides the full range of services needed to solve the environmental problems facing industry today. For additional information, or to find out more about Sumas, please do not hesitate to contact us.

Sumas Environmental Services Inc. (Sumas) is the only full service environmental contractor in western Canada to independently offer the full range of environmental services in-house, including site remediation, on- and off-site water treatment, on- and off-site soil remediation and disposal, and hazardous waste treatment and disposal.

Sumas provides excavation plans for a variety of removal/remediation action projects with an emphasis on minimizing cost, disruption of facility operations, and overall excavation of soil by evaluating contaminant distribution and geological characteristics with the consultants.

The development of detailed excavation plans includes an evaluation of available subsurface data to determine the most appropriate method of removal. Depending on site-specific considerations, a variety of methods may be employed to facilitate the excavation including selective excavation, bench excavation, slot cutting or mass production excavation. Excavation procedures are designed to accommodate slope stability, lateral earth pressure, and potential surcharge from adjacent structures. Sumas also employs field screening techniques to assist in the segregation of impacted soils during excavation to consistently strive for volume reduction and to maximize reuse of suitable soils on-site.

Sumas operates and maintains a diverse fleet of equipment such as vacuum trucks, excavators, loaders, trucks, and various water treatment systems. Sumas personnel are highly technical and fully trained with years of experience in environmental and remediation services. By providing all services in house, Sumas can manage costs on time and ensure that the project is completed on time in the most cost effective way.

The air is extracted by a vacuum blower or a vacuum pump. By creating negative pressure gradients in a series of zones within the soil, an airflow is induced which causes volatilization of the volatile hydrocarbons. The VOC laden air stream, together with the entrained moisture and dust, is extracted from the impacted soil to a vapor extraction system (VES). VOCs in the vapor stream are treated using granulated activated carbon, catalytic/thermal oxidation, or internal combustion engines.

Sumas also conducts in-situ remediation through dual phase vapor-liquid extraction process also referred to as Bioslurping. Bioslurping is an innovative in-situ remediation technology that utilizes an applied vacuum to recover Light Non-aqueous Phase Liquids (LNAPL) through small diameter recovery piping (Slurp-tube) while simultaneously biodegrading adsorbed phase hydrocarbons in the vadose zone due to the inherent replenishment of oxygen that occurs. Aerobic conditions created by the addition of atmospheric oxygen creates a "bioreactor" degrading the smear zone contaminants in-situ.

Bioslurping and bioventing are proven in-situ remediation technology that have been successfully applied in many site remediation projects involving petroleum hydrocarbons. Sumas has mobile, skid-mounted units for rapid deployment, and the design/construct capabilities to accommodate a variety of project requirements.

In cases where contaminants are discovered, this will be removed by selective excavation and removal of the contaminated soil. The contaminated soil is placed in on-site bio-cells for treatment or loaded on trucks for off-site disposal at one of the Sumas owned facilities. Upon confirmation by the consultant that all contamination is removed, the excavation is backfilled, the fill compacted, and the site returned to existing surroundings.

Sumas' vacuum trucks are used in remediation work such as removal of fuels and sludge, drilling mud, excavation dewatering, and waste water removal. The content (wastewater, fuel, semi-solid waste, etc.) is transported to Sumas owned facilities for further treatment and/or disposal. The trucks are also used during industrial cleaning and high pressure washing of industrial equipment and chemical and fuel storage tanks.

Sumas Environmental Services Inc. (Sumas) is the only full service environmental contractor in western Canada to independently offer such a wide range of services as site remediation, on- and off-site water treatment, on and off site remediation at disposal, and hazardous waste treatment and disposal.

System components include gravity phase separation, filter press, pH adjustment, heavy metal flocculation and settling, and carbon filtration. Upon completion of treatment and confirmatory analysis, the water is discharged to the GVRD Sanity Sewer. The discharge is monitored on a regular basis and fully permitted by the GVRD under permit SC-100029-FSA.
