David Ruttan

Since 1972, Mr. Ruttan has been practicing engineering geology and hydrogeology with a variety of companies in several countries. Since 1985, as an independent hydrogeologist and groundwater modeller, he has been providing hydrogeological services on a sub-consulting basis. His experience ranges from Phase 1, 2 and 3 environmental site assessments and site remediation, supervision of pumping tests and drilling, piezometer installation and packer testing, pumping test analysis and complex computer groundwater flow and contaminant transport modelling. He has extensive experience in modelling including international experience spanning over 30 years using Modflow/Modpath/ MT3D99/MT3DMS and related programs and POLLUTE and HELP. Mr. Ruttan has had wide-ranging experience in assessing hydrogeological conditions for dewatering projects and modelling dewatering including proposed large pits and quarries. He also has extensive contaminant transport modelling experience including modelling subsurface heat flow impacts on cold water streams, landfill leachate, nitrates from septic systems and hazardous chemicals. He has done many determinations of groundwater and rainfall inflows at proposed construction sites for obtaining Permits to Take Water. While at WSP Canada he mentored a groundwater modelling group. He is currently involved in determining municipal well capture zones and wellhead protection areas for two municipal water supplies in Ontario. He has participated in many public meeting and hearings to present the finding of modelling projects. He has worked on groundwater modelling and geological/hydrogeological projects in most of Canada, New York, New Jersey, Idaho, North Carolina, Nicaragua, Venezuela, St. Kitts and Nevis, and Saudi Arabia. He is a registered professional engineer in the province of Ontario, Canada with a B.A.Sc in Geological Engineering from the University of Toronto 1972.
