Why Use LDE Environmental – Land Contamination Remediation services
Our highly skilled Scientists are ‘suitably qualified and experienced practitioners’ (SQEPs) and chartered environmental practitioners (CEnvP) who can provide you with technical advice at the forefront of legislation, guidance and the industry’s best practice. We will find cost-effective solutions for your land issues.
Developing, subdividing, carrying out earthworks, or otherwise changing your land use may require a Preliminary or Detailed Site Assessment (PSI/DSI) to determine if your land has been exposed to harmful material according to the National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health (NESCS), Regional and Unitary Council Plans and the Contaminated Land Management Guidelines (CLMG).
Preliminary Site Investigations (PSI’s) establish if your property has or has previously had a HAIL (Hazardous Activities and Industries List) land use on or around it. The HAIL details the operations likely to cause land contamination due to hazardous substance use, storage or disposal.
If your property is identified as having a HAIL activity undertaken on it a DSI report will likely need to be undertaken.
The DSI will quantify the contaminant levels and the subsequent strategy for dealing with it. This may be do nothing and your project can continue if the levels are low enough.
Where contaminants are found in levels above the Ministry for the Environment (MfE) accepted levels, in consultation with you the client mitigation, steps will be put in place to support your project while meeting all necessary compliance requirements. A Remediation Action Plan (RAP) followed by a Site Management Plan (SMP) and Site Validation Report (SVR) are just some of the services we offer.
Don’t get caught out with contaminated land halting your project. Our experienced environmental services team will help you navigate the process, from testing to resource consent application, and ensure your project complies with National Environmental Standards (NES).
LDE also offers a quick and efficient Soil Quality Investigation (SQI) to inform on various offsite disposal options. An SQI can be conducted before earthworks commence or on stockpiles of soil already excavated from a development, considering the MfE Landfill Waste Acceptance Criteria and WasteMINZ Technical Guidelines for Disposal to Land.

LDE’s Environmental -Land Contamination Specialities
LDE are specialists in a diverse range of contaminated sites, including:
Asbestos contamination has become a significant problem in New Zealand. Asbestos in soils pose an inhalation risk to exposed populations. Land converted to residential use puts families in danger of exposure through building, renovations, and gardening, so testing for asbestos before significant projects is essential.
Our Environmental specialists often work in multi-disciplinary teams with other professionals to ensure successful project outcomes.
Our highly skilled Scientists provide you with technical advice at the forefront of legislation, guidance and the industry’s best practice. We will find cost-effective solutions for your water issues.
LDE's Water Contamination project examples include:
LDE's Preliminary Freshwater Ecological Assessments can cover:
LDE has strong relationships with freshwater ecologists who can provide further expertise and advice as required.
Our Environmental specialists often work in multi-disciplinary teams with other professionals to ensure successful project outcomes. LDE can offer various complementary services such as engineering geology and civil engineering to undertake such work as:
Combining these competencies and complementary services ensures that we can address multiple requirements for our clients.
Industry, businesses, councils often have operations which result in discharges into the environment in the form of groundwater, surface water and air discharges. To ensure discharges minimise environmental impacts, discharge permits are issued that can include conditions for regular monitoring, reporting and improvement.
LDE’s team of experts can prepare and negotiate monitoring regimes and undertake regular compliance monitoring and reporting to address discharge permit conditions and Council bylaw monitoring requirements.
Compliance Monitoring Capabilities
LDE's Environmental Compliance Monitoring Capabilities include:
LDEs team of environmental scientists have extensive experience with asbestos in both soils and in buildings. We are currently able to provide services for Class B and Asbestos Related Work with the aim of expanding our services to Class A Work. LDE can complete investigations for asbestos in soils and buildings and advise on remedial works so that it meets the New Zealand Guidelines for Asbestos in Soils and Health and Safety at Work (Asbestos) Regulations 2016.
LDE can offer asbestos services such as:
LDE utilise geospatial analysis to solve geospatially complex problems. We have the capability to gather, display, and manipulate geospatial data such as aerial imagery, historical information and GPS coordinates with associated attribute data within our environmental team. Examples of geospatial work completed by team members include modelling of contaminant levels in soil and groundwater, land use and landcover assessments, catchment sizing and stormwater flow calculations, slope impact assessments, needs analysis and assessment for irrigation, refuse and septage services, and wetland development. The team are proficient in QGIS and ArcGIS software and online tools.
LDE can offer the following geospatial services:
LDE provide acid sulphate soils assessments and acid sulphate management plans for susceptible areas. The assessment includes field pH and pH(fox) assessments, as well as laboratory analysis for Chromium Reducible Sulfur (CrS) and Suspension and Peroxide Combined Acidity and Sulphate (SPOCAS). Groundwater samples will also be collected and analysed as part of the assessment. All results are compiled into a factual report. An acid sulphate management plan is developed to identify how acidic soils can be avoided, minimised and/or neutralised to prevent harm to infrastructure and the environment.
LDE's Acid Sulphate Soil Capabilities include:
LDE offers Environmental Advisory Services such as:
