Simple contamination risk assessment

Leaks from underground storage tanks or spills on the forecourt, pose one of the biggest sources of groundwater contamination. Not only can leaks cause huge environmental damage, they can result in massive remediation costs, huge fines and even law suits should the contamination go beyond your site boundary. An efficient groundwater monitoring solution can considerably reduce this risk.

Regulations in NSW and Victoria require storage tank operators to take all practicable measures to prevent pollution. As well as mandatory leak detection systems like SIRA, under NSW guidelines site operators must have groundwater monitoring wells installed and then monitored every six months.

In Victoria, operators are required to undertake groundwater monitoring if the site is sensitive. However, we can’t stress enough the importance of introducing a regular groundwater monitoring system as part of a proactive risk management strategy.

We believe any responsible fuel retailer sitting on thousands of litres of underground fuel SHOULD KNOW the potential for groundwater contamination both on your site/s and neighbouring properties. This can open up huge liability concerns – not to mention huge remediation cost blowouts – that can be prevented with an efficient well monitoring system.

By incorporating groundwater monitoring, not only do you reduce your site’s environmental liability, but by keeping groundwater monitoring records, you can also greatly increase the value of your asset should you wish to sell in the future. A record of your site’s history is very valuable information for any prospective buyers. As the market leader in leak detection solutions, our highly qualified groundwater consultants offer a comprehensive groundwater quality risk assessment, measurement and groundwater analysis that can help you:

  • Understand your groundwater monitoring obligations
  • Determine if your site is sensitive using an experienced hydrogeologist*
  • Establish a baseline of groundwater quality
  • Assess your site for the presence of contamination by taking a sample of the water quality from your groundwater monitoring well

*Applicable in Victoria only

How it works

  • Leighton O’Brien’s services include conducting a site assessment to establish the location and condition of your groundwater monitoring wells
  • We gauge the depth to water and check for any petroleum product residing on top of the water in your well monitoring system
  • If a layer of petroleum is present in the monitoring well, a sample will be collected to evaluate the contamination, noting the colour and thickness in the bailer
  • We provide a comprehensive and easy to interpret report with recommendations for further action (if any)
  • Where no further action is required, we develop an ongoing groundwater sampling and quality management plan to monitor groundwater quality
  • Where further action is required, develop a plan to identify, contain and remediate the contamination while meeting compliance obligations
  • Waste generated during the collection of groundwater quality samples is removed from site and disposed of appropriately
