“…In the coming years, many countries will have dramatic increases in significant tunneling projects throughout major cities and population hubs. For example, in Australia, there are currently 18 major tunneling projects in the expression-of-interest or tender phases, including: the Snowy Hydro Project 2.0 in New South Wales, which will use underground tunneling to link dams and to generate power, creating 750,000 cubic meters of fill [8]; sections of the Forrestfield Airport Link in Western Australia, with 8.5 km of rail tunnels, which is expected to generate one and a half to two million tons of fill [9], and the North East Link in Victoria, with two six-kilometer twin tunnels [10]. In most of these projects, PFASs will be encountered when tunneling [11], which leads to an extraordinary amount of PFAS-contaminated construction waste to be disposed of.…”

Cleaning up Forever Chemicals in Construction: Informing Industry Change

Per- and polyfluorinated alkyl substance (PFAS) contamination has been found in the construction spoil of many major projects, and there is growing concern about the health and environmental implications of these “forever” chemicals. In a context where construction and tunneling have experienced substantial growth, Australia and other countries are still developing their PFAS management. This study used convergent interviews to surface the key common issues that are associated with the management of PFAS contamination in the construction industry. The construction industry appears stuck in their ways and extremely financially driven. Regulation is not working because of poor enforcement and policing from the Environmental Protection Agency (EPA). The EPA could look to employ individuals with more construction industry experience in order to become a strong regulator in the industry, as well as to streamlining decision-making processes, while maintaining quality. To speed up changes in the management of PFASs within the construction industry, large organizations could be targeted by the relevant sustainability rating scheme, and there could be further use of the alliance models to research, develop, and implement PFAS treatment methods.
