Per- and polyfluoroalkyl substances (PFAS) were detected in water samples collected from our client’s on‐site public water supply well in March 2022, as part of the quarterly sampling required by the MassDEP drinking water program. The reported detection of PFAS started an inquiry by MassDEP and prompted a site audit. The MassDEP required the sampling … Read more
Portions of the five-acre, industrial Classic Chemical site were developed as early as 1891. Historical operations – including cloth manufacturing and dying; leather dying and tanning; chemical manufacturing; and, most recently, paper sorting and recycling – left a legacy of contamination and regulatory concerns. Challenge To achieve regulatory compliance of this complex site under the … Read more
Challenge The Barnstable Fire District Water Department (BFDWD) Wells #2 and #5 have the highest concentrations of PFAS within the public water system, approaching the Massachusetts maximum contaminant level for a combined concentration of 6 compounds. In addition, more stringent PFAS regulations from the USEPA were anticipated in the future. Iron and manganese concentrations would … Read more
Challenge Per- and polyfluoroalkyl substances (PFAS) were detected in White Pond, the backup water supply for the Town of Maynard, Massachusetts. The Massachusetts Department of Environmental Protection (MassDEP) subsequently initiated a subsurface investigation to evaluate whether the possible historic use of aqueous film-forming foam (AFFF) at the Massachusetts Firefighting Academy (MFA), which is located upgradient … Read more
Challenge The Barnstable Fire District Water Department (BFDWD) required the reactivation of its Well Pump Station #1 and a new Treatment Building #3. Well #1 is the only well of the 5 Barnstable Fire District wells which was found to not contain PFAS, so it was imperative to reactivate as quickly as possible. Being an … Read more
Challenge The client’s proposed 150-acre, mixed-use development is adjacent to an industrial site at which plastics and coatings were used. The adjacent site has been identified by the state as a source of per- and poly fluoroalkyl substances (PFAS) contamination contributing to soil and groundwater impacts. Because PFAS have been identified as a potential hazardous … Read more
Challenge Emery & Garrett Groundwater Investigations, a division of GZA (EGGI/GZA), has provided groundwater consulting services to a former military base for 15 years as part of the base’s redevelopment. The mixed-use development proposed for the site will be exclusively reliant upon groundwater resources to meet its current and anticipated potable water supply needs, utilizing … Read more
Challenge Since 2010, GZA has performed investigation and post-remedial action monitoring on behalf of the New Hampshire Department of Environmental Services (NHDES) at the New Hampshire Plating Company (NHPC) Superfund Site on the bank of the Merrimack River. NHPC had operated an electroplating facility there from 1962-1985 resulting in groundwater contamination that included metals, cyanide, … Read more
Challenge In a rural New England community, groundwater contaminated with per-and polyfluoroalkyl substances (PFAS) was discovered in a community supply well located near a former industrial facility that historically handled PFAS-containing materials. PFAS contamination associated with this site was also found in soil, sediment, and surface water. The facility is now owned and operated by … Read more
