Senior Environmental Scientist
Carl completed a BSc in Biology in 2008 at the University of Auckland and commenced work as an environmental consultant for Mitchell Partnerships Ltd, focussing on resource consent acquisition. During his time with Mitchell Partnerships, Carl has been involved assisting a project team on a number of large developments including wind farms, hydro stations, thermal power stations, geothermal developments and mining activities. In addition to resource consent acquisition, he has actively been involved in developing and preparing adaptive management plans, consent compliance reports, policy and planning analysis, and summarising a diverse array of technical information for inclusion with supporting documentation for resource consent applications.
In 2013, Carl completed a Post Graduate Diploma in Science (Environmental Management) with distinction, again from the University of Auckland. The diploma focussed on the application of legislation to complex development issues and the application of different problem solving techniques to promote high quality decision making amongst environmental professionals. His research topics included analysis of sustainable management principles against renewable energy projects under the RMA 1991 and on the application of National Policy Statement on Indigenous Biodiversity within large scale developments.
Since joining Geosciences, Carl has conducted, and managed a variety of preliminary, detailed, and soil quality site investigations for a range of sites from current and former horticultural land to current and former industrial sites. In addition to site investigations, he has also been involved in designing a range of remediation projects to provide for future landuses of impacted sites and the validation of those projects following completion of remedial works. He has also provided due diligence risk analysis in respect of potential contamination issues for pre purchase assessments on a number of industrial sites.
Carl brings a diverse range of knowledge gathered from over 7 years consulting experience and offers expertise in investigation, analysis, remediation, validation, and the preparation of associated technical documentation including site investigation reports, remedial actions plans, site validation reports, environmental management plans, adaptive management plans, resource consent applications, and consent compliance reports.
Brodie has recently returned to Geosciences after attending the 100-year Gallipoli ANZAC Landing Commemorations in Turkey, and followed by spending a year overseas on an OE playing rugby for Kirkby Lonsdale Rugby Football Club, and exploring Europe.
Now back in New Zealand, and back at Geosciences Ltd, he is picking up where he left off, further developing on his previous contaminated land and environmental experience, knowledge, and interests.
Brodie completed a BSc in Geography and Environmental Science at Massey University, graduating in 2013, and followed this with a Postgraduate Diploma in Environmental Management from Massey University, graduating in 2014. The focus of his most recent study was on soil and water contamination, primarily from nutrients and heavy metals from agricultural, horticultural, and industrial activities. He also studied eutrophication of waterways by wastewater and agricultural discharges at both individual waterway and catchment levels; the pathogenic contamination of waterways; and the production of EIA reports.
Prior to joining Geosciences in 2014, Brodie has gained work experience working in a Chemistry Laboratory on a seasonal basis during his study, performing a range of environmental and food-related analytical testing.
Jean completed a Bachelor of Science, majoring in Anatomy, at the University of Dunedin in 2009, and after a gap year working as an environmental technician, he returned to Dunedin to complete a Bachelor of Arts, majoring in Computer Science, in 2013.
Jean is a computer enthusiast. In addition to looking after GSL’s information technology requirements, Jean has also been involved in numerous soil quality field surveys, from preliminary site inspections to detailed site investigations.
David has a BSC hons degree in Geology from the University of Edinburgh and a Masters Degree in Geothermal energy and Geology from the University of Auckland. He has extensive field work experience from his studies, including soil and rock sampling, geological mapping, and laboratory analysis (X-ray diffraction and spectroscopy and Electron microscopy).
In his most recent studies for his Masters project he worked on a selection of silica sinter samples from the Coromandel Peninsula using an array of analytical methods to determine their evolution. In 2015 he was selected from his graduating class to present the findings of his study to members of the geothermal research and energy industries over the course of two days in Rotorua and Taupo.
David has recently joined Geosciences Ltd and is currently involved in extensive fieldwork programs that include soil sampling and analysis of former horticultural land that are designated for large scale residential development, the redevelopment of a school complex and a large scale remediation project of a former native plant nursery.
Chris entered the contaminated land industry in 2010 when he began his postgraduate research into the effects of gold mine pollution on mammals. Following the completion of his BSc Honours, he expanded his research into the dynamics of gold mine pollution and local food webs as an indicator of potential human risk. Upon completion of his MSc, he began consulting to the southern African mining and smelting industries, focussing on the remediation of severe contamination.
Prior to immigrating to New Zealand, Chris worked on contaminated land and remediation projects in South Africa and Namibia. Projects included contaminated land assessments focussing on the rehabilitation and management of severe arsenic trioxide and heavy metal contamination. This included desktop investigations, intrusive field sampling in Hazardous Materials conditions, and laboratory work.
Following his arrival in New Zealand, Chris joined Geosciences Ltd bringing his solid skill set developed over five years in the contaminated land consulting industry to our company. He has since been involved in a number of contaminated land investigations, including preliminary and detailed site contamination investigations, human health and environmental risk assessments as well as remediation and validation projects. Investigations include industrial and commercial sites, road corridor land, former horticultural land, and general green and brown field areas designated for commercial, industrial, and residential development.
Our Mission is to facilitate in a cost effective and professional manner the restoration and maintenance of land and water from the impact of human endeavours where these may cause degradation in human health or the environment.
