Here is what some of the speakers had to say about their presentations:
Identification and assessment of risks from a very large, complex former industrial site
"Large, complex former, industrial sites present special challenges for the risk assessor whether looking at human health or risks to the water environment. These challenges may be exacerbated by long development programmes and by the presence on non-standard receptors that need to be considered. The presentation will discuss development of the conceptual site model where several sources may be present and ways of considering unusual receptors."
More effective investigation of chemically and radioactively contaminated land using on-site measurements
"On site measurements can reduce the cost of investigating and developing brownfield sites, but they are treated with a lack of trust my many users and regulators. The solution to this problem is to evaluate and state the uncertainty of all measurements (on site and in lab-based) and allow for this uncertainty in the assessment of the hazard, exposure and risk. Recent case studies on chemically and radioactively contaminated sites will be used to illustrate this solution. The interpretation on both on site and lab-based measurements will be made using the Support Tool for Reliable Environmental Measurement (STREM), which includes the Optimised Contaminated Land Investigation (OCLI) method. This will be used to show that on site measurements often have larger uncertainty than their lab-based equivalents, but can be equally fit-for-purpose in many situations."
The assessment of risks to human health from PAHs in soils and dust
"PAHs are prevalent in soils in many urban areas of the UK and can arise from a variety of sources, including the historical legacy of burning coal. Simon will summarise the results of the SoBRA one day workshop held in York earlier this year which aimed to identify key uncertainties in the assessment of risks to human health from PAHs in soil and to find where there is (and is not) consensus of opinion on how these uncertainties are best managed. Exposure assessment for the inhalation of dust pathway was one of the key uncertainties identified and Chris will summarise recent work conducted by Reading University where PAH concentrations in indoor dust were measured and compared with concentrations in nearby garden and allotment soils."
Technical Risk is Commercial Risk - risk management post downturn
"This presentation will use NHBC statistics to illustrate the effects of the economic downturn on the housing sector, and will discuss changes in the ways that land is purchased by developers. It will reaffirm the purpose and role of NHBC and our approach to risk management. The presentation will conclude by showing how NHBC’s Land Quality Endorsement scheme has been used on a number of major brownfield sites to reduce technical risk for all parties, thereby providing comfort regarding the technical (and hence commercial) feasibility of the site”
A new approach to semi continuous indoor air monitoring of VOCs
"This case study presents one of the first commercial applications of an exciting new technology, the VOC GasClam. This device for semi-continuous monitoring of VOCs in air was used to supplement human health risk assessment at a property adjacent to a leaky petrol station. Delegates will gain insight into a new technology, and will be interested to discover how semi-continuous monitoring data can be incorporated into human health risk assessment for gases in indoor air."
