Our landfill team has strong experience in landfill hydrogeochemistry, assessment, remediation, design, management, and monitoring, coupled with expertise in sportsfield and open space design and soil specification.
iEnvi is now one of Australia’s fastest organically growing consultancies with offices in Sydney, Melbourne, and Brisbane and more than 100 supporting specialist consultants.
We work with experts from universities, individuals and companies to form the best team for providing innovative approaches, without the overheads of corporate structures and offices.
Understanding Land Systems
Often our parks, sportsfields and open spaces are underlain by historical filling activities or landfills. Our multidisciplinary team has expertise in helping government bodies and private companies address problems associated with managing active and former landfills, as well as developing on top of them and mitigating environmental risk in ongoing operations.
