Save time and protect your development with 3rd party verification

Read More

Everyone agrees that Britain needs new homes, and quickly. Targets at both local and national levels increasingly focus on the redevelopment of brownfield sites; with the dream of transforming derelict space into thriving communities. Of course, the simple message sold to voters doesn’t encompass the difficulty of clearing and converting a former industrial unit into flats, or building on old landfill. Ground-gas can be a danger in any development but, as the focus switches to brownfield, developers are increasingly being expected to officially validate that effective ground-gas measures are ensuring the safety of future site users.

Environmental Monitoring for the Onshore Oil & Gas Industry Event

Read More

Ground Gas Solutions Limited (GGS) are delighted to be involved in a new course on the environmental monitoring of water and methane for the onshore oil and gas industry. This new course  is delivered by Envireau  Knowledge in partnership with Envireau Water, Peter Dumble Hydrogeology, GeoWater, In-Situ and GGS and will take place on the 25th August 2015 at the University of Birmingham.

 

The course is aimed at a relatively high level, to demonstrate to onshore oil and gas operators why monitoring is required and what the key issues are for their industry. It is directed at operating companies and those responsible

BS 8485:2015 – Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings

BSI have just published the long awaited revision to the 2007 document.

Toxic, asphyxiating or explosive gases can leak from the ground and accumulate in buildings, posing health risks. The standard describes how to characterize sites and prevent the entry of carbon dioxide and methane into new buildings. This revision has now been substantially expanded and revised to reflect changes in good practice and reference other standards since the last edition was published. 

 

Key Changes

The revised document provides the highest level of guidance in the UK on this subject and while keeping to the ethos and spirit of the simple point scoring system of design, it is much expanded to provide clearer guidance on:

  • interpreting gas monitoring data
  • selecting membranes
  • changes to gas protection scores
  • worked examples
  • user flow charts

And in addition to methane and carbon dioxide it also provides recommendations through new annexes on radon and volatile organic compounds (VOCs).

Hazardous gases may be present in the ground naturally, or from contamination, mine working or buried wastes. Two of the major risks are methane, which is flammable (explosive in confined spaces) and an asphyxiant, and carbon dioxide, which is both toxic and an asphyxiant.

The standard provides guidance on site investigation, determining ground gas parameters and using those to identify protective design solutions. It is not prescriptive – recognising that there are many factors involved, that a range of design solutions are available for different situations, and that professional judgement is often needed. Emphasis is placed on justification and recording of risk assessments and design decisions so that the whole process will be transparent for consultants, developers and regulators. 

 

Ground-Gas Solutions Comment

Ground Gas Solutions works hard to promote best practice in the contaminated land sector and believes that this document provides a further step forward to improved ground-gas protection for the UK construction industry.

GGS/PAG “A-Z of Ground-Gas” – everything you need to know in a 2 day seminar!

Read More

Given the serious dangers that ground gases can pose, it is no surprise that local authorities are increasingly demanding effective ground-gas protection measures be installed and verified. Ensuring that you’re up to speed with best practice in the entire process – from data collection and risk assessment to the final verification can be a critical skill for many industry professionals.

New and improved innovative landfill monitoring services

Read More

GGS has developed a range of innovate services arising from the results of the highly successful ACUMEN research project. The ACUMEN project is now entering it’s final few months, if you are unaware of the project and wish to find out more information please follow the link here and here.

 

These new and improved services, along with our well established ground-gas  monitoring services, can provide landfill operators and / or owners with a range of tools to assess key aspects of landfill gas management.  Should you wish to find out more on how GGS can measure and quantify landfill gas emissions

How does continuous monitoring save you money?

Continuous ground-gas monitoring involves the use of unmanned data collection instrumentation.  On the face of it, this can seem to be an expensive way to collect ground-gas data.  Read on to find out why it can actually be the solution to saving you money.

GGS involved in Closed Landfill Workshop

Read More

Ground Gas Solutions will be speaking at a closed landfill workshop as part as the ACUMEN project.  The event is free and will take place in Tullamore, County Offaly, Ireland.

 

The full day workshop will focus on approaches to reducing methane emissions from closed landfills that have been demonstrated by the ACUMEN project, such as small scale landfill gas engines, low calorific gas flaring and bio-oxidation technologies.  The workshop will also address the monitoring techniques to help site owners assess a site that then can be used to better understand the ground gas regime or improve upon gas management systems.

Health risks of radon in buildings

Read More

What is radon?

Radon is a gas produced from the decay of uranium, a naturally occurring element in the earth’s crust. Radon is radioactive, emitting harmful alpha radiation when it decays.

Radon is present in outdoor and indoor air, usually in small amounts. We breathe it in and out all the time. If a radon atom decays while inside our lungs, the alpha radiation released may damage lung cells. This has the potential to cause lung cancer. It is estimated that 1,100 people die prematurely every year from radon exposure, just in England and Wales.

3 ways continuous ground-gas monitoring saves you time

Read More

Ground-gas monitoring programmes can hold up brownfield development. Spot monitoring periods can be prescribed for up to 12 months. Continuous monitoring can provide a solution to this.

Continuous monitoring involves the use of unmanned data collection instrumentation. There are many benefits to collecting continuous data, including improved risk prediction, but continuous monitoring also saves you time. Here’s how:

The Onshore Energy Services Group Publish a Series of Factsheets

Read More

The onshore energy services group (OESG) have a series of factsheets published on their site to inform on aspects of the oil and gas industry. Each factsheet provides a very useful resource for policymakers and public stakeholders to understand the processes of extracting energy, along with the risks, the safeguards employed to protect against these risks, and the regulatory framework within which oil and gas extraction takes place.

 

All the factsheets can be found on this link www.oesg.org.uk/resources/factsheets
