We charge a single, low flat fee per sample tested. It’s the same price per sample whether you’re having one sample tested or 10.
As one of NSW’s most experienced work health and safety consultancies, we have many years’ experience dealing with sites with difficult or complex contamination issues, from residential lots to large commercial and industrial sites. We are familiar with, and comply with, the relevant guidelines including the National Environment Protection (Assessment of Site Contamination) Measure.
Contaminated land assessments
Two things shape how we work. We identify asbestos in soil in our own NATA-accredited laboratory, and recover and send the wider site chemistry, including metals, hydrocarbons, PFAS and solvents, to an external NATA-accredited laboratory. And we are an independent consultant: we investigate, assess, write the remedial or management plan and validate the work, but we don’t carry out the removal or remediation. A separate licensed contractor does that. Because we don’t sell the clean-up, our reports have no stake in the outcome. Our contaminated land reports are signed off by Michael Edwards, our Certified Environmental Practitioner (Site Contamination Specialist), a sign-off recognised by the NSW EPA that gives a development application the best chance of progressing through council. The full four-stage process is set out on our Contaminated Land Assessments page.

Frequently asked questions
-
It’s the work of finding out whether a site is contaminated, with what, how much, and what it means for how the land can be used. It usually runs in stages: a preliminary site investigation of the site’s history and condition, a detailed site investigation with sampling and lab testing, then, where needed, a remedial action plan and a validation report once the work is done. See our Contaminated Land Assessments page for the full process.
-
No. Airsafe is an independent consultant. We investigate, assess, plan and validate. The remediation itself is carried out by a separate licensed contractor, which we can tender and oversee for you. Because we don’t sell the clean-up, our reports stay independent.
-
For asbestos in soil, yes, in our own NATA-accredited laboratory (No. 2959). The wider chemistry of a contaminated site goes to an external NATA-accredited laboratory, with samples recovered on site by our consultants. Using an external lab for that work keeps the results independent.
-
We’re based in Sydney and carry out contaminated land assessments across Sydney, Newcastle, Wollongong and country NSW. Travel is built into our quotes for sites outside the metropolitan area. If you have a site anywhere in NSW, call us on 1300 888 338.
