Langan Emerging Contaminants Experience
Langan provides an integrated mix of environmental and engineering consulting services in support of design and application of remediation technologies in treating emerging contaminants (EC) for our corporate, energy, developer, property owner, public agency and institutional clients.
Langan’s environmental scientists and professionals understand the technical and regulatory challenges posed by ECs – particularly 1,4-dioxane, perfluorinated and polyfluorinated alkyl substances (PFAS). We are applying our expertise to guide our clients in assessing and addressing EC concerns, and we are contributing to the development of new approaches for managing and remediating ECs through our involvement with various state-led regulatory stakeholder processes and through our participation in PFAS team recently formed by the Interstate Technology and Regulatory Council (ITRC).

Hyde Beach Residence Dewatering
This project involves the construction of 40+ story condominium tower and parking garage. The site, a former gasoline service station, was contaminated by petroleum hydrocarbons in the soil and groundwater, which was very shallow and required dewatering to enable construction. Excavations were to occur in an organic peat layer and the Miami Limerock, which is highly permeable but not suitable for many methods of dewatering. Langan provided dewatering design and permitting services for multiple phases of the foundation and utility construction at the entire project site.
