Keynote Waste Regulation and the Construction Industry: The Regulators' Update
-
Waste and Legality: What it Means to your Site
Exploring some of the main areas of potential liability (civil and criminal) associated with waste on development sites and possible consequences of unlawful deposits, including waste removal notices and confiscation orders under the Proceeds of Crime Act.

AGS Guidance on Waste Classification for Soils Review and Update
The presentation is on a guidance note produced by AGS specific to the classification of waste soil
This guidance is specific to waste soil and builds on WM3
- It provides guidance on the amount of sampling required;
- Segregation of the site in to zones of differing properties / waste class;
- Assistance in assigning the likely metallic species in the soil, so that appropriate hazardous properties can be adopted; and
- Discusses the use of statistics to interpret data sets
-

Reclaiming Landfills for Development
- Practicality of landfill redevelopment;
- How the regulatory regime has developed to accommodate this
- How industry can be proactive in ensuring such developments are successful and ‘safe’ in the future.

Landfill Remediation, Detailing the Options Available
-
Case Study: Waterside Drive
The site is a historic landfill and so required extensive investigation and characterisation to determine potential risks to both site users, surrounding properties and the adjacent river from contaminants within the landfill and changes that may arise from the redevelopment. Following the characterisation a detailed remediation methodology was developed in conjunction with the local authority and Environment Agency which was then closely monitored whilst being carried out, including regular groundwater monitoring to confirm that risks to potential receptors were being appropriately managed.

Coastal Landfills, Dealing with Leaching of Contaminated Material
Historically, it was common practice to dispose of landfill waste in low-lying estuarine and coastal areas where land had limited value due to flood risk. Such ‘historic landfills’ are frequently unlined with no leachate management and inadequate records of the waste they contain.
Some historic coastal landfills have already started to erode and release waste, and with the anticipated effects of climate change, erosion events are likely to become more frequent. Strategies to mitigate the risk of contaminant release from historic landfills such as excavation and relocation or incineration of waste would be prohibitively expensive for many countries.
Therefore, it will be necessary to identify which sites pose the greatest pollution risk in order that resources can be prioritized, and to develop alternative management strategies based on site specific risk.
-
Satellite Based Ground Motion Surveys for Environmental Safety and Security
Ground motion surveys have a variety of environmental applications, including the monitoring of landfill sites. Over landfill sites subsidence results as a consequence of shifting solid waste and the decomposition of garbage and can be an indication of leachate, which may cause pollution. Land stability is also an important prerequisite for the reclamation of landfill sites.
GVL's wide-area land motion maps provide the ideal source for site-specific reports on ongoing and historical ground stability and subsidence risks. These can be used to support a wide range of environmental assessments and planning applications.
