At EnviroScience Solutions, we work hand-in-hand with the construction and infrastructure sector to ensure the health of your worksite, surrounding environment, and workforce are protected.

Specialising in the identification, monitoring and management of contaminants and hazardous substances in building materials, air, soil and water, our services are often called upon prior to the commencement of a project to identify, test, and monitor for any environmental issues.

With more than 50 technical and scientific specialists based across regional New South Wales, our team is extremely mobile, ensuring minimal disruption or delay to your project. We also offer an emergency response (less than 24 hours) to most regional locations.

Meanwhile, our in-house NATA accredited laboratory ensures quick turnaround on asbestos testing. And we also specialise in the identification and management of Naturally Occurring Asbestos (NOA) found in rocks, sediment and soil, which could be disturbed when constructing roads, rail, dams, pipelines and transmission towers.   

In our 15 years of operation, we have undertaken many projects for State and Local Government, Tier 1 and Tier 2 construction companies, multi-nationals, local and regional firms, and insurance companies. We have also held multiple NSW Department of Land and Housing contracts (LAHC), directly for the LAHC and under Joss Facility Management and O’Donnell & Hanlon.

Holding ISO accredited quality, environment and WHS systems, we are approved under the NSW Government Prequalification Schemes and for Consultants in Construction and are a member of the Schools Infrastructure NSW Panels for Occupational Hygiene and Environmental Services.

EnviroScience Solutions is also an approved Consultant Hygienist under an NSW Land and Corporation panel of providers for assessment, remediation or replacement of public housing in NSW.  

Other common hazardous materials we test, and monitor for, include soil contaminants and crystalline silica. We also carry out comprehensive airborne dust level monitoring (including routine dust monitoring during the operational period), vibration monitoring to protect sensitive buildings and underground infrastructure, noise monitoring, and water testing and monitoring.

EnviroScience Solutions is an industry leader in protecting the health of personnel working onsite, by conducting individual occupational health assessments for repetitive strain injuries such as, hand and arm vibration, and respirator fit testing for inhalable and respirable dust.

We pride ourselves on being at the forefront of innovation, and continually work to identify new hazards and develop solutions to remediate and manage them. This includes different types of tyre contaminants (6PPD) and microplastics.

Case Studies

EnviroScience Solutions was engaged to conduct an initial site assessment and remediation works following the internal contamination of a residential property during its refurbishment. The friable asbestos contamination was created by tradespeople unknowingly cutting and drilling fibre cement ceilings and walls that contained chrysotile, amosite and crocidolite asbestos.

Prior to the commencement of remediation works, the entire building was sealed within a bubble and a thorough smoke test of the structure took place to ensure no fibres could be released throughout the duration of the project. To ensure the property was free of friable dust on internal surfaces, all soft furnishings and ceiling insulation were removed, while all hard surfaces were vacuumed and wet-wiped. Walls and timber frames remaining in-situ were cleaned and sprayed with a PVA solution to minimise the potential of free fibres.

During remediation, ongoing air monitoring took place and was provided each morning to workers and the client to validate the works were being conducted in a safe environment. Upon completion of the remediation, a visual inspection, clearance air monitoring and adhesive tape samples were collected to ensure with high confidence that the site had been fully remediated.

EnviroScience Solutions was commissioned to undertake preliminary investigations following the growth, and infestation, of mould within the wall cavities of a hospital ward.

The mould, which occurred due to a faulty thermostatic mixing valve that had released an unknown quantity of water, was thoroughly investigated to assess likely pathways of water and mould growth. Inspection holes were drilled into walls of the ward and once the areas of concern were identified, the walls were dried with portable air driers while the ward remained closed.

Several days after the initial issue had been addressed, EnviroScience technicians returned to site for further assessment. Moisture readings, swabs and bio-tape impressions of the wall cavities were taken, and results returned positive for fungal spores within the ward. Nursing administration was contacted, and access was limited until fungal clearance could be issued.

Recommending HEPA vacuuming and wiping down of hard surfaces with a fungal biocide, remediation works were then carried out by a professional cleaning company.

Following these works, EnviroScience conducted validation sampling which found the wall cavities were dry and were able to be resealed. Clearance air samples showed normal fungal ecology and the ward was commissioned to reopen safely.

EnviroScience Solutions was engaged to conduct indicative soil sampling along a rail corridor in the Central West of New South Wales to identify potential areas of contamination prior to removal and subsequent disposal of the soil.

The exact history of the verge soil along the rail corridor was unknown, except that the deposits appeared following rain events and the subsequent flood. Based on industrial activities in the catchment area, the site was identified as potentially containing contaminants.

A visual inspection of the sample location found a silty residue, with seven samples taken from the rail corridor. Samples for TRH, BTEXN, PAH and heavy metal analysis were collected in laboratory supplied clean glass jars, while the soils were couriered to NATA accredited laboratories for analysis.

Analysis at each sample location for heavy metals, PCBs, PAH’s and total recoverable hydrocarbons were found to be below the detection limit, or below the threshold, for General Solid Waste.

EnviroScience recommended further investigation may be warranted if soil is to be removed and disposed of from any other location outside the parameters of the rail corridor, while any further investigations should be completed in accordance with the Waste Classification Guidelines (EPA, 2014).

Based on the analysis undertaken, the rail corridor soil material was found to fit the requirements for General Solid Waste and could be disposed of accordingly.
