We believe that soil and water are two of mankind’s most valuable assets, and seek to remediate, re-use and manage soil and water adversely impacted by human activities in a sustainable and cost effective manner.

Geosciences Ltd was established in 2009 to provide services and advice to industry and to the commercial, residential and agricultural sectors on matters related to soil contamination, surface water and and groundwater pollution. In 2023 we are proud to have joined forces with SQN.

Our staff understand the regulatory framework that dictates investigation, remediation and validation processes alongside having expertise in industrial trade activity obligations and disposal to land requirements. Our client driven approached ensures a smooth process for obtaining consent from local government for any earthworks activities related to impacted land.

We undertake work throughout New Zealand.
