Sustainable Remediation and Management of Contaminated Sites
Remediation isn't merely about restoring a piece of land for compliance purposes; it's about ensuring that the solutions are sustainable, cost-effective, and tailored to the unique attributes of each site.
Where traditional remediation approaches like 'dig and dump' might seem straightforward, they don't always account for the full lifecycle costs of a landfill, or consider the human health risks associated with vehicle emissions and traffic incidents.
Landfill disposal is a quick fix that fails to recognise deeper complexities and can create intergenerational pollution issues if managed incorrectly. It is also incredibly costly.
That’s where HAIL Environmental comes in – we provide deep expertise, innovative techniques for sustainable remediation, and ensure a comprehensive solution tailored to the requirements of your specific situation.
The Challenges of Sustainable Remediation
For your development to proceed, you need to resolve any contaminated land issues identified in the Detailed Site Investigation (DSI) phase. But selecting the right approach and carrying it out properly often comes with inherent complexities.
Here are a few challenges that we regularly encounter:
-
Remediation options might be limited due to the need for swift actions and keeping project development timelines on track.
-
Remediation in itself can have adverse effects. For example, removing soil to landfill is not only expensive, it also entails heavy vehicle movements, carbon dioxide emissions, and serious crash risk. It takes up limited and valuable resources - landfill space, fuel, and often replacement clean fill and topsoil are required. Without careful consideration of these issues, remediation can result in more risks being generated than the contamination itself.
-
For some clients, displacing soil from its origin is more than an environmental or risk issue; it affects the spiritual and cultural ties to the land. In these situations, local remediation solutions that don’t remove soil from the rohe are essential.
Tailored Solutions, Proven Results: How We Can Help
Choosing HAIL Environmental isn't just about hiring a service provider; it's about partnering with experts who genuinely understand the nuances of sustainable remediation.
Here’s why:
-
We are Aotearoa’s most experienced team of contaminated land consultants. Unlike many generalist consulting and project management firms, we only look after one type of work: identifying and resolving contaminated land issues. This enables us to deliver excellent sustainable remediation outcomes for your project.
-
Tight deadlines? Internal staff at capacity? We'll act as your agent, quickly securing the right consents, arranging disposal permits, managing contractors, and undertaking validation sampling & reporting to ensure that your development can proceed in a timely manner.
-
If required, we can formally assess and manage remedial decisions in accordance with the ISO 18504:2017 Soil Quality - Sustainable Remediation standard.
-
From common contaminants to persistent organic pollutants listed on the Stockholm Convention’s POPs list, we can work with almost any hazardous substance, and have a proven track record you can trust.
-
Our team has experience in the design, construction, and monitoring of in situ remediation systems for soil, groundwater, soil vapour, and sediment. We can deliver a wide range of sustainable remediation techniques that treat contaminants locally, instead of removing soil and transporting it to landfill.
-
Sometimes the most cost-effective solution is to manage contaminants on a site through a combination of physical and institutional controls. Physical controls such stabilisation or encapsulation are designed to isolate the contamination, thereby eliminating exposure pathways. They can often be built into a redevelopment project to avoid extensive cleanups or soil removal.
-
Developing a better understanding of site specific risks can often lead to eliminating or reducing remediation requirements, providing clients or future land owners with certainty that they are not at risk.
-
Some solutions (such as implementing physical controls) require ongoing management and monitoring to verify their long term effectiveness. We can look after these ongoing responsibilities on your behalf.
Steps to Resolving Your Contaminated Land Issues
Resolving your contaminated land issues and securing the green light for development involves a series of methodical stages. Clients typically identify the need for remediation as a result of undertaking a detailed site investigation (DSI).
Once you know that remediation is required, here’s how the process works:
-
We start by preparing an assessment of the remediation options that are feasible within your timeframes and for the specific contamination issues that you are trying to mitigate.
-
This document outlines key details such as the remediation methods proposed, timelines, and expected outcomes.
-
Before work can begin, your local council needs to review the remediation action plan and grant consent to proceed.
-
With consent in hand, we will then manage your remediation project - often in collaboration with external contractors and other specialists.
-
Once the remediation work has been completed, we prepare a site validation report to verify that the contamination issues have been adequately resolved.
-
The final stage involves your local council reviewing the validation report and confirming the remediated site's readiness for development.

“HAIL Environmental was nominated by HEB Construction as the Suitably Qualified and Experienced Practitioner (SQEP) for Kiwirail’s Waltham Mechanical Hub Project, playing a key role in contamination investigations, producing DSIs, obtaining resource consents, and developing a good working relationship with Environment Canterbury. Their approach, which considered multiple solutions to determine the most effective way to deal with contaminated materials, has enabled the re-use of approximately 14,000t of material on-site, saving the client in excess of $2.5m - a ‘perfect example of what a collaborative approach should look like.’”
