Remediation design and management

ESG Environmental has experienced remediation specialists with national and international experience in the design, trialling, implementation and management of both insitu and exsitu remedial programs. Our team has remediated sites that have been impacted by hazardous building materials (including asbestos) and contaminated soil, soil vapour, sludge and groundwater. 

Depending on the land use setting and your requirements, the need for active remediation may be avoided if it can be shown through an ecological/human health risk assessment that the risks are acceptable for the impact to remain in place. Alternatively, we can work with you to develop a site specific solution to minimise any required remedial works that safely manage the risk presented by the contamination, within your project’s constraints.

Cost effective, sustainable and risk based solutions are often found by managing contamination issues on-site. Our remediation specialists can provide innovative options to complement your project’s objectives using a variety of technologies and management measures such as, reuse of materials, on-site treatment and containment systems. We have implemented many novel remedial technologies and low cost, low impact techniques to achieve remedial targets. More substantial remedial programs may require a tailored strategy sometimes requiring multiple technologies. With remedial targets and potential limitations in mind, we can work with you to develop an appropriate outcome resulting in significant cost savings and avoidance of ‘over treatment’.

Groundwater, surface water and soil

ESG Environmental’s hydrogeologists, geoscientists and geochemists have extensive experience in a wide range of groundwater, surface water and soil studies. Our firm has undertaken numerous investigations from relatively small sites to more complex environments. In most situations, our investigations are conducted in a staged approach, designed to clarify the key environmental risk drivers. Working closely with you we can tailor a successful outcome to your project, without over delivering.

ESG Environmental has established long term relationships with expert primary contractors and service providers allowing us to achieve greater efficiency and cost benefits for your organisation’s projects.

State-of-the-art equipment used in our investigations are largely company owned and are regularly calibrated, serviced and updated (as needed) by our senior technician. Our equipment includes water quality meters, hand-held x-ray fluorescence analyser (XRF), photoionisation detectors, landfill gas monitors, flow meters, soil vapour probes and associated in-situ testing equipment, interface probes and water level meters, below ground cable/pipeline.

The XRF analyser is a specialist field tool used to assess the elemental composition of materials in real time. This provides many benefits during assessments (provision of instant indications of site impact) and remedial programs (avoids many iterations of the remediation-validation cycle). ESG Environmental also have other specialist equipment utilised for remedial monitoring.  As part of our innovative approach we can design, fabricate and install specialist investigative and remedial equipment as required.

Construction dewatering

We provide tailored practical dewatering solutions for your site, no matter the size, from car-stacker pit dewatering, to full scale bulk groundwater management for multi-level basements.  We can provide an effective solution to ensure that your project remains on-time and on-budget.

Water discharge and management

Discharge of excavation water must be managed in accordance with the regulations of the relevant Water Authority for your site. ESG Environmental can undertake the appropriate water testing to determine the suitability of excavation water for discharge to either stormwater or sewer.  

We advise on the most cost effective way to manage the discharge of water and if required will negotiate a Trade Waste Agreement on your behalf.

If a Trade Waste Agreement is required, we will provide and install the required apparatus to fulfill Trade Waste requirements (i.e. settling tanks, electromagnetic flow meter). 

Tailored practical dewatering solutions

ESG Environmental has extensive experience working within the Melbourne area and is familiar with the complexities and potential issues which arise during construction dewatering.  Our knowledge and experience will allow you to manage your dewatering as effectively as possible. 

We offer the following dewatering services:

•  Pre-construction groundwater investigation 
•  Groundwater modelling 
• Well point/spear sytem dewatering 
• Multi-stage well point dewatering
• Deep well dewatering systems
• Sump dewatering
• On-site installation and system management in a safe and timely manner
• Trade waste agreement negotiation with the  relevant water authority
• Water testing and screening for suitable disposal options
• On-hand advice for the duration of the project
