Alan Fowler is a Senior Principal based in New Hampshire with more than 25 years of experience focused on the assessment and remediation of contaminated sediment. Alan is a recognized expert in the field of contaminated sediment management and is responsible for developing the technical and regulatory strategies for high-liability sediment sites.
Alan's technical expertise includes dredging and capping design for sediment containing PCBs, coal tar/NAPL, dioxins/furans, and mercury. His expertise also includes developing engineering plans, technical specifications, cost estimates and contracting strategies for sediment remediation projects. Alan helps his clients by developing and implementing investigation, remediation, and risk management strategies that meet regulatory requirements. He has worked with clients whose sites are regulated under RCRA and CERCLA.
His project experience spans remedial investigations, feasibility studies, remedial designs, and construction oversight. This includes multiple large-scale dredging and capping efforts, such as serving as a design engineer for the dredging and capping of a Northeastern U.S. river with approximately 2.6 million cubic yards of sediment containing PCBs; designing, permitting and overseeing construction for a two-acre confined disposal facility (CDF) constructed in Boston Harbor; and managing the design and implementation of a large time-critical removal action for the Beech Creek Superfund site. He has also worked on multiple Natural Resource Damage Assessment and Restoration (NRDAR) projects including the development of restoration projects and the use of restoration-based approaches for settlement purposes.
Additional U.S. experience includes Ashtabula River, Berry's Creek, Coosa River, Hudson River, Ohio River, Columbia River, Lake Okeechobee, New Bedford Harbor, Newtown Creek, Passaic River, Portland Harbor, San Francisco Bay, and San Diego Harbor. Alan's project experience in Canada includes Howe Sound (Squamish, B.C.) for a large-scale site with mercury containing sediment; the Fraser River (Burnaby, B.C.), where he coordinated the design and construction of a large project to dredge and cap coal-tar-containing sediment at a former wood-treating site; Beaverdams Creek/Channel (Thorold, Ontario), where he managed design and construction of a large PCB-dredging/capping project; and the Pemberton Avenue site (North Vancouver Harbor, B.C.) where he led the dredging and capping design for sediment containing coal tar/NAPL.
