Lead exposure: no safe level – act now to end exposure

A unique blend of environmental and geotechnical expertise to support projects across all stages.

Charlotte is a Senior Engineering Geologist and Certified Environmental Practitioner who works within our environmental science team. She undertakes contaminated site investigations across Canterbury, the West Coast and Nelson, and supports projects from preliminary stages through to remediation.

Much of Charlotte’s role involves navigating contaminated land considerations and reporting to meet NES CS requirements. Her experience spans investigation through to consent, earthworks supervision and long-term monitoring, as well as sites affected by historic industrial use, asbestos, petroleum hydrocarbons, pesticides and closed landfills. 

Charlotte has also worked within our geotechnical team where she was involved in citywide geotechnical site assessments following the Christchurch earthquakes. She draws on this experience to bring a strong understanding of geotechnical site conditions and development constraints to contaminated land assessments. 

Technically great at all things environmental, particularly asbestos.

Gareth leads our environmental science team and specialises in the identification of contaminated sites and their remediation, management and safe use.

His experience includes investigation, risk assessment, remediation and consenting, and sites associated with chemical manufacturing, aviation, waste management, heavy and light manufacturing, transport, downstream oil and gas, timber treatment as well as defence sites in New Zealand and internationally.

With a background in contaminant hydrogeology, Gareth helps evaluate the potential effects of land contamination on groundwater and surrounding surface water receptors. He’s a Certified Environmental Practitioner Site Contamination Specialist (CEnvP SC) and prepares contaminated land assessment reports to meet NESCS requirements.

Gareth also holds qualifications in asbestos surveying and management. He supported local and central government and private clients following the Canterbury and Kaikōura earthquakes, and also assists with planning refurbishments or demolition where asbestos‑containing materials may be present.

Takes a hands-on approach to site remediation and contaminated land.

Julian is an environmental scientist based in our Christchurch team who investigates the environmental aspects of a variety of projects - from large-scale developments through to small residential sites, as well as commercial, agriculture and horticulture sites.

His role commonly centres on contaminated land assessments, sampling and remediation, supporting projects as they move through investigation and management stages. 

Alongside this, Julian plays a key role in consent monitoring, where he is involved in assessing groundwater and surface water quality across Canterbury, Nelson, Tasman and the West Coast. This includes work related to dewatering consents, water-take consents and erosion and sediment control monitoring.
