Led by a forensic mycologist.
NSJ EnviroSciences is an independent environmental consultancy, led by David Lark, Principal Mycologist and Indoor Environmental Professional. We identify the biology of water-damaged buildings and interpret what it means for the people living and working in them. The laboratory analysis is a tool we use; the work is the judgment that surrounds it.
One conviction
For more than two decades, David has worked on a single idea: in a water-damaged building, it is rarely the amount of mould that decides who becomes unwell — it is how the people inside respond to it. Two households can share the same exposure and fare completely differently.
Reading that difference — weighing the environment against the people in it — is what an environmental mycologist is for, and it is what NSJ is built around.
The person behind the report
David is a forensic mycologist and Indoor Environmental Professional with more than twenty years in environmental mycology, including building and leading a dedicated environmental laboratory. He is a published co-author on peer-reviewed research into how indoor exposure affects human health, and he prepares independent expert reports to the standard required for cross-examination in court and in AFCA disputes. That depth sits behind everything NSJ delivers — whether you hold a $549 screening kit or you are a solicitor briefing an expert witness.
“Expert independent advice to help get things back on track. David’s knowledge and experience has been so reassuring... if you need someone highly experienced who can give you the right advice, I would highly recommend David and his team.”

What we actually assess
We assess the indoor environment and the exposure of its occupants — not mould alone. Where it matters, that means the wider biological picture: bacteria (including Actinobacteria and endotoxin), allergens such as dust-mite residue, and the moisture that drives them all. We read the building as a system, and the people in it as the reason for reading it. What we do not do is judge how the building was constructed — whether it was built or repaired to standard is the engineer's remit, not ours. Our lane is the environment inside, and what it means for health.

Talk to the scientist
Most people find us partway through something stressful — an illness without an explanation, a dispute that will not resolve, a remediation they are not sure worked. A short conversation with the person who will actually read your result is often the quickest way to understand what you are dealing with.
