LHC team members have carried out numerous aquifer mapping projects for BC MOE & GBC over the last 10 years.  The projects have been completed in all regions of the Province and about half of the total 1000 aquifers mapped in BC were mapped by our team members.  The BC Aquifer classification system was employed and this includes aquifer vulnerability, level of development and productivity plus a statistical analysis of all well record data.  Aquifer mapping (delineation) is one of the first steps in ground watershed studies.

Aquifer Storage Recovery (ASR) component of the Englishman River Water Intake Project which will increase the water supply capacity for Parksville, RDN and Qualicum Beach to meet increased water demand up to the year 2050.  The target storage capacity will be 1,000,000 m3 in the ASR well field.  The ASR wells which store treated drinking water will allow a major reduction in the water treatment plant size and represent a significant cost saving over alternative water storage options.

A comprehensive regional groundwater study is being undertaken.  Phase 1 of the work included a stress analysis on the 12 mapped aquifers in the CVRD, monitoring well data analysed and correlated with precipitation data, geology modelling and groundwater flow calculations.  Exploration drilling sites were indentified with potential for wells with up to 390 L/s capacity.

Water supply and Wastewater disposal to ground hydrogeological and environmental impact studies for a 500 Lot development ongoing since 2005. Regional geology modelling and well pumping impact on the Cowichan River are major components of the project.  Three separate Hydrogeologists have peer reviewed the LHC analysis for this high profile development.

Between 2007 and 2010 LHC carried out hydrogeological assessments for the wastewater disposal to ground facility upgrading and fire protection well testing.  The project included an Environmental Impact Assessment of sewage disposal impacts and designing a monitoring well network to determine long term impacts.  Well protection planning and retrofitting drinking water wells with surface seals was included in the upgrading.

Water supply and wastewater disposal for a 350 lot development on Cowichan Lake.  Work included an Environmental Impact Study on wastewater disposal to ground and groundwater source development for water supply.  Tasks included geology modelling with cross-sections, well capture zone delineation, GWUDI water testing, soils testing, monitoring well drilling and groundwater sampling.

Study of potential development impacts on Goudie Creek flows and water quality.  The study included geologic modelling, estimation of groundwater recharge, estimation of groundwater discharge to the creek in summer and streamflow measuring plus watershed delineation.

Regional Groundwater Study including geology modelling with cross-sections, calculation of well pumping volumes compared to well capacities, delineation of groundwater development target zones. Recommendations for management of the groundwater resource were developed.

Regional groundwater study of the Mill Bay area.  Geologic modelling, aquifer flow calculations and water demand estimates.  Water balance determination and groundwater exploration, two successful wells completed with capacity to supply 500+ homes.

Regional groundwater assessment with the objective of locating water sources for fracking CBM production wells and identifying options for fracking water disposal including injection into deep saline aquifers.  Area of study – Comox coal basin from Nanaimo to Courtenay-Comox.

Regional groundwater study and groundwater resource development with geophysical exploration and production well drilling. The water supply on the Island was increased by 40%.

Drilling site selection, well construction supervision and pumping tests.  Groundwater resource exploration and development project.  Work included geology modelling and aquifer computer modelling plus geophysical exploration. Location – St. Kitts and Nevis, Caribbean.
