Engage Environmental Services has the ability to safely conduct sampling of building materials and soils for asbestos analysis.  We use NATA accredited laboratories for sample analysis. We have licensed asbestos assessors on staff.

We can conduct Hazardous Material Surveys for small renovations, demolition projects, risk registers, commercial sites, industrial premises and individual sample collecting to ease the mind of renters, potential homeowners, home owners, leasing agents, strata companies and business owners.

When is the last time your Asbestos Risk Register was updated?

Our team has licensed asbestos assessors (and trusted LAA subcontractors) who can provide specialist advice, strategies, methodologies and clearances for all forms of asbestos contamination.

We also undertake asbestos air monitoring to quantify any risk to site workers or surrounding residents when removing asbestos containing material, moving asbestos impacted soils or during friable asbestos work.

Our staff have experience in performing the whole range of LAA duties for friable and bonded asbestos.

We work closely with Licensed Asbestos Removal companies to independently check and assess the works performed by Class A and Class B Licensed Asbestos Removalists. We can provide Clearance Certificates for small, medium and large projects.

Our Risk Registers can be used to assist in developing costings for renovations, demolitions and ongoing maintenance work. Under the current Safework NSW technical notes Risk Registers are to be updated every 5 years.

Compliance monitoring is undertaken on a routine basis to ensure the NSW EPA EPL conditions of a licensed industrial or commercial activity are being met.

Petroleum storage and distribution is a major source of soil and groundwater contamination. Leaks can occur in underground storage tanks (USTs), above ground storage tanks (ASTs) and underground petroleum storage systems (UPSS) which includes, fill points, tanks, pipework and bowsers.

Petroleum leaking from USTs or ASTs can have significant, adverse impacts on people, property and the environment. Without the aid of groundwater monitoring and statistical inventory reconciliation analysis (SIRA) leaks within an UST can go unnoticed for a lengthy period of time. A leaking UPSS can cause significant impacts for people, the site, adjoining properties and the environment.  There can be significant costs in remediation of a site and penalties from EPA

Our team can with the aid of subcontractors install groundwater monitoring wells or sample the existing groundwater monitoring wells to assess whether an underground storage tank has leaked, contaminating the groundwater, and provide ongoing UST monitoring services at six monthly intervals as per the current best industry practice. In addition we are able to provide a wetstock reconciliation statistical analysis service in line with SIRA guidelines to provide monthly tracking.

We can help with:

• Undertaking routine monitoring as per EPA EPL conditions;
• Assist with EPA EPL annual returns;
• Due diligence site investigations for new purchases or refinancing;
• Detailed Site Investigation for change of use;
• Installation of groundwater monitoring wells;
• Finding existing groundwater wells;
• Inspect and sample existing groundwater wells
• Design remediation strategies for UST removal;
• Remediation of contaminated soil;
• Validation of Tank Pits;,
• UST and UPSS compliance monitoring services;
• SIRA services;

Reporting for Tank Pit Validation, UPSS Monitoring, Groundwater Assessments, validation soil and groundwater assessment to determine if remediation works has been performed to a satisfactory standard and due diligence for new purchases

Soil vapour consists of volatile chemicals that occupy the porous space within soil. Engage Environmental Services personnel can assess soil vapour through both active and passive sampling methods to assist in developing a soil vapour risk assessment.

A risk assessment utilises site specific exposure scenarios to determine the potential harm posed by volatile contaminants

Our team has decades of experience in preparing Environmental Site Assessments (ESA) for a variety of purposes, from simple desktop review and site inspection, through to a detailed technical assessment of the soil and groundwater conditions at a site.

Stage 1 Preliminary Site Investigation

A Stage 1 Preliminary Site Investigation (PSI) may be required as part of a Council development application (DA) for redevelopment, before a change of land use or as part of due diligence prior to the sale/purchase/lease of a property.

Our in-depth Preliminary Site Investigation incorporates:

A desktop study of a site’s history, including current and historical aerial photographs, council documentation, certificates of title; an inspection of the site (with or without sampling) to identify potential sources of contamination and associated contaminants. This is where our Licensed Asbestos Assessors are invaluable on site inspections.

The Preliminary Site Investigation report will conclude whether a site is suitable for a proposed land use or if a further investigation is required through a Detailed Site Investigation (DSI) or targeted DSI.

Stage 2 Detailed Site Investigation (DSI)

A Stage 2 Detailed Site Investigation (DSI) typically incorporates the findings of the Stage 1 PSI, and includes soil, and groundwater sampling (if required) of the Site.  The DSI is undertaken to identify contamination, and then delineate the vertical and lateral extent of the contamination. The DSI then assesses potential contaminant migration and exposure pathways.

The results of the DSI are used to determine whether a site is suitable for a proposed land use, or if remediation is required through the form of Remediation Action Plan (RAP).

Engage Environmental Services can provide a clear understanding of the soil profiles that exist on a site, along with onsite tracking and classification of soils for off site disposal.  This is essential to provide time efficiencies and staying within project budgets.

Prior to the removal of potentially contaminated soils from a site to a licensed waste or recycling facility, soils must be classified in accordance with NSW EPA Waste Classification Guidelines and the NSW EPA Orders and Exemptions.

Disposing of materials to landfill has become the least preferred option of State environmental authorities and as such is an expensive exercise.  This means that effective onsite management and treatment of contaminated soils becomes increasingly important.

We can assist in maximising onsite reuse through supervising sorting of materials which can reduce remediation costs significantly. We can liaise with EPA and NSW EPA Accredited Site Auditors to develop specific exemptions for projects.

Asbestos in Soils

Guidelines for the assessment of asbestos in soils that permit the safe onsite management of soils with low levels of asbestos now exist. Identifying the type and nature of asbestos contamination in soils is crucial to assessing the risk and implementing the most appropriate management approach. Currently the industry is developing a new benchmark and reviewing best practice for asbestos in soils.

Our team has licensed asbestos assessors (and trusted LAA subcontractors) who can provide specialist advice, strategies, methodologies and clearances for all forms of asbestos contamination.

We can also undertake asbestos air monitoring to quantify any risk to site workers or surrounding residents when moving asbestos-impacted soils or during friable asbestos work.

Acid Sulfate Soils

Engage Environmental Services can prepare Acid Sulfate Soil (ASS) Management Plan to manage earthworks on your site if ASS have been identified at your site or the site is located within an area of potential ASS on Local Government and State Government plans or documents.
