Municipal Board hearings involving over 25 public and private sector
projects.
- Presentation of expert testimony at
civil litigation proceedings involving contaminated sites.
- Familiar with the preparation of site
investigations and witness statements for litigation purposes.
- Experience working with legal teams
to interpret complex technical reports and develop defence strategies
for litigation proceedings.
Water Supply Projects:
- Completed groundwater exploration,
drilling, and test pumping of numerous water supply wells for subdivision
and commercial/industrial developments in southern Ontario. Projects
involve preparation of detailed hydrogeological reports to obtain permits
to take water.
- Completed testing and evaluation of
several high-capacity water supply wells in Uxbridge, Ontario.
- Peer reviewed the water supply and
sewage disposal options feasibility study for a golf course and conference
centre development in the Town of Caledon.
Environmental Impact Assessments:
- Investigated the hydrogeologic setting
of a potential 40-million tonne landfill site to serve Toronto.
- Investigated the hydrogeologic setting
of a potential 25-million tonne landfill site in an open pit mine near
Marmora, Ontario.
- Conducted hydrogeologic studies for
over 50 operating and potential landfill sites, including private landfills,
industrial landfills, and a variety of small and large (over 20M tonnes)
municipal landfills.
- Conducted preliminary assessment studies
of over 100 abandoned landfill sites for the Ontario Ministry of the
Environment and Metro Toronto.
- Designed and implemented constructed
wetlands and infiltration basins for leachate and stormwater treatment.
- Designed and implemented leachate pumping
wells to control water table mounding in landfills.
- Designed and implemented various leachate
collection systems for remediating landfill impacts during operation
and after completion.
- Completed detailed hydrogeological
assessment of proposed residential development lands on the Oak Ridges
Moraine (ORM) in Richmond Hill, Ontario. Work was completed as part
of Master Environmental Servicing Plan and Secondary Plan studies. Conducted
long-term groundwater and surface water monitoring, drainage basin surveys,
calculated water balances and developed constraint mapping for the development,
focussing on potential impacts to wetland and kettle lake complexes.
Work was presented at OMB hearing regarding development on the ORM.
- Conducted a pilot test and feasibility
study to use infiltration facilities for stormwater management and maintenance
of groundwater recharge conditions in two development areas on the ORM.
- Completed detailed hydrogeological
assessments of several proposed residential and golf course development
sites on the ORM in Uxbridge, Ontario. Conducted water supply drilling
and testing, sewage effluent disposal testing, drainage mapping, groundwater
and surface water sampling, calculated pre- and post-development water
balances and developed best management practices to maintain recharge
and hydrogeological function of the development lands.
- Involved in the design and implementation
of rapid infiltration basins for effluent disposal at the Innisfil landfill.
- Completed aquifer mapping, water budget
calculations and assessment of stormwater management options for the
Downsview Development Project.
- Completed hydrogeological assessments
of proposed development lands (residential and commercial) in Stouffville,
Ontario. Studies in support of Secondary Plan and Draft Plan involved
detailed characterization of geological setting, groundwater flow conditions,
groundwater/surface water interactions, drainage, pre-and post-development
water balance, and identification of development constraints to maintain
hydrogeological functions.
- Conducted a hydrogeological investigation
to assess shallow subsurface flow conditions, infiltration capacity
of soils and recharge conditions for the construction of stormwater
management facilities at a subdivision development in Cobourg, Ontario.
- Completed a hydrogeological assessment
and feasibility study for sewage effluent disposal from large-scale
leaching beds at a subdivision development site on the ORM in East Gwillimbury.
Greenhouse Gas Projects:
- Developed a bioreactor system at a
landfill in Toronto that reduces greenhouse gas emissions. The system
creates aerobic conditions in the landfill which prevents the production
of methane (a greenhouse gas). In addition, the bioreactor system controls
odourous gas emissions, accelerates the decomposition process and allows
healthy reforestions over the entire site.
- Designed and implemented a variety
of positive-pressure barriers to control landfill gas migration. These
systems provide a high level of protection to abutting properties and
eliminate the need to exhaust and treat the landfill gases.
- Evaluation of subsurface landfill gas
migration patterns around landfills and development of gas venting systems.
Remediation Projects:
- Designed a leachate collection system
consisting of 26 wells and a gravity drain on the site perimeter to
capture a leachate plume at the Innisfil landfill site (1995).
- Designed and implemented a groundwater
containment well system for the Uniroyal Chemical plant at Elmira, Ontario.
The system includes several pumping wells that captured contaminated
groundwater in deep sand and gravel aquifers beneath the plant site
(1991).
- Designed and implemented a combined
groundwater/vapour containment system for a fuel and chlorinated solvent
spill site in Toronto. The system includes a vertical geomembrane barrier
for vapour control, a gravity drain to collect contaminant plumes, a
sub-floor vapour extraction system for soil clean-up and a groundwater
flushing system.
- Supervised the clean up of PCE-contaminated
soil at an industrial property in Mississauga, and provided certification
of the site clean-up (1996).
- Provided liaison with government, municipal
and public representatives to resolve remediation strategies for numerous
landfills and industrial spills throughout Ontario.
Landfill Projects:
- Involved in a pilot-test of aerobic
landfill technology to reduce methane emissions at a municipal landfill
in Simcoe County, Ontario.
- Completed hydrogeological investigations
at a flyash waste disposal site in Mississauga. The work included long-term
water quality and landfill gas monitoring and the design and testing
of a groundwater containment well system.
- Completed detailed hydrogeological
studies to address leachate migration, designed leachate and gas control
systems, and developed long-term monitoring programs to support proposed
expansion hearings for several large southern Ontario landfills.
- Completed an impact assessment for
a pulp mill waste disposal facility focussing on surface water issues.
Responsible for annual monitoring reports for the facility in compliance
with Ministry of the Environment Certificate of Approval requirements.
- Coordinated and completed risk assessments
at 14 closed landfill sites in Metropolitan Toronto, focussing on landfill
gas impacts.
- Responsible for the annual hydrogeological
evaluations and monitoring reports for various municipal and private
landfill sites.
Aggregate Resources:
- Completed a detailed hydrogeological
evaluation of an active aggregate extraction operation in Caledon, Ontario.
- Conducted a hydrogeologic assessment
of existing and proposed sand and gravel extractions for TCG Materials.
The work included an assessment of the impacts of below water table
gravel extraction on adjacent groundwater resources and a cold water
stream. The work included successfully defending an application for
an extraction license at an OMB Hearing.
- Conducted hydrogeologic assessments
of proposed gravel extraction below the water table and potential groundwater
and surface water impacts for Cox Construction at two Puslinch Township
properties.
- Assisted in investigations of groundwater
contamination and interference complaints; reviewed applications for

- Involved in an aggregate resources
inventory of the Bruce Mines to Blind River area for the Ontario Geological
Survey. Responsible for assessing the potential of the Nipissing Diabase
as an aggregate material. See publication list for reference.
- Completed a detailed hydrogeological
evaluation of an active aggregate extraction operation in Caledon, Ontario.
