Recent Projects

Permit to Take Water (PTTW) Applications and Monitoring

G&M has been involved with numerous PTTW applications and related annual monitoring programs. PTTW applications have been conducted in relation to mines, quarries and pits, commercial, agricultural and construction projects. We have completed the hydrogeological and surface water studies required to support the applications.

Hydrogeological Studies – Development / Servicing

G&M has completed several hydrogeological investigations in order to support land development applications through groundwater availability and review of potential interference. These studies have included well inventory surveys, pumping test analyses, and water quality sampling.

Hydrogeological Studies – Landfill Development

G&M have conducted several Hydrogeological Investigations to support the development of landfill properties. These investigations have included well installations, monitoring, the development of conceptual models, and contaminant migration modelling, for both municipal and private clients.

Hydrogeological Studies – Sewage Systems (D-5-4)

G&M regularly conducts hydrogeological investigations in support of sewage system applications to the MOE or MOE D-5-4 Studies. These studies have been used to support development of new areas, lot severances, or the use or installation of a subsurface sewage disposal system over 10,000 litres per day.
