Specialist scaling its consultancy once again, emerging engineering firm Hexa has launched a specialist PFAS (per- and polyfluoroalkyl substances) investigation and assessment service led by a newly appointed expert in the contaminant.
Will Spraggs has joined as an associate in the Hexa Land team, which was formed in 2024 to support Hexa’s expertise in ground engineering for complex brownfield sites. With over 13 years’ experience in geo-environmental and contaminated land investigation, including complex PFAS investigation and assessment at former Ministry of Defence barracks and commercial airports, Will is set to play a key role in enhancing Hexa’s PFAS service offering.
PFAS (per- and polyfluoroalkyl substances), often referred to as ‘forever chemicals’, are a growing topic of national conversation and an emerging environmental priority in the UK. PFAS contamination is commonly associated with firefighting foams and industrial use, particularly across airfield, defence, fuel infrastructure and manufacturing sites. A forensic approach to tackling these sites, informed by the latest evidence, is essential.
“PFAS are an evolving area of environmental risk,” says Will. “Official guidance is still developing, so we will be taking a pragmatic, evidence-led approach to support clients facing this challenge.”
Only three PFAS compounds are currently restricted in the UK, though the government is exploring further legislation. With understanding and regulation rapidly advancing, Hexa is positioning itself at the forefront of PFAS investigation, assessment and remediation support services.
“I was ready for a change and a new challenge, with the culture at Hexa appealing to me. It’s an ambitious and quickly growing company and the team has given me the scope to apply my expertise, which complements the existing offering too.” Hexa provides end-to-end land contamination support, from early-stage due diligence checks, site investigation and sampling, through to risk assessment, regulatory support and remediation design. In bolstering the business’s geo-environmental capability, Will’s appointment demonstrates Hexa’s ambition to lead PFAS expertise in the sector.
Matt Lomas, director at Hexa, said:
“We’re always looking at evolving our services to better support industry challenges and we are proud to be able to attract top talent from across the sector to support us in doing that. Will’s drive and expertise will boost our capability in this emerging area, strengthening the growth of our PFAS services as the business continues to scale. We’re looking forward to seeing how he shapes the team.”
