Rey D, Briggs M, Tokranov A, Lind H, Scordato P, Iery R, et al.
Sci Total Environ . 2025 Jan; 964:178533. PMID: 39862507
Groundwater-dependent ecosystems in areas with industrial land use are at risk of exposure to a PFAS chemicals. We investigated one such system with several known PFAS source areas, where high...

Pickard H, Ruyle B, Haque F, Logan J, LeBlanc D, Vojta S, et al.
Environ Sci Technol . 2024 Oct; 58(43):19440-19453. PMID: 39412174
Most monitoring programs next to large per- and polyfluoroalkyl substances (PFAS) sources focus on drinking water contamination near source zones. However, less is understood about how these sources affect downgradient...

Hill N, Becanova J, Vojta S, Barber L, LeBlanc D, Vajda A, et al.
Environ Toxicol Chem . 2024 Jun; 43(8):1795-1806. PMID: 38896102
Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with toxicity in wildlife and negative health effects in humans. Decades of fire training activity at Joint Base Cape Cod...

Ruyle B, Thackray C, Butt C, LeBlanc D, Tokranov A, Vecitis C, et al.
Environ Sci Technol . 2023 May; 57(21):8096-8106. PMID: 37184088
Drinking water contamination by per- and polyfluoroalkyl substances (PFAS) is widespread near more than 300 United States (U.S.) military bases that used aqueous film-forming foams (AFFF) for fire training and...

Barber L, Pickard H, Alvarez D, Becanova J, Keefe S, LeBlanc D, et al.
Environ Sci Technol . 2023 Mar; 57(14):5544-5557. PMID: 36972291
Aqueous film-forming foams historically were used during fire training activities on Joint Base Cape Cod, Massachusetts, and created an extensive per- and polyfluoroalkyl substances (PFAS) groundwater contamination plume. The potential...

Tokranov A, LeBlanc D, Pickard H, Ruyle B, Barber L, Hull R, et al.
Environ Sci Process Impacts . 2021 Nov; 23(12):1893-1905. PMID: 34779453
Elevated concentrations of per- and polyfluoroalkyl substances (PFAS) in drinking-water supplies are a major concern for human health. It is therefore essential to understand factors that affect PFAS concentrations in...

Bradley P, LeBlanc D, Romanok K, Smalling K, Focazio M, Cardon M, et al.
Environ Int . 2021 Mar; 152:106487. PMID: 33752165
Background: Humans are primary drivers of environmental contamination worldwide, including in drinking-water resources. In the United States (US), federal and state agencies regulate and monitor public-supply drinking water while private-supply...

Ruyle B, Pickard H, LeBlanc D, Tokranov A, Thackray C, Hu X, et al.
Environ Sci Technol . 2021 Mar; 55(6):3686-3695. PMID: 33667081
Water supplies for millions of U.S. individuals exceed maximum contaminant levels for per- and polyfluoroalkyl substances (PFAS). Contemporary and legacy use of aqueous film forming foams (AFFF) is a major...

Lane Jr J, Briggs M, Maurya P, White E, Pedersen J, Auken E, et al.
Sci Total Environ . 2020 Sep; 740:140074. PMID: 32927542
The hydrogeology below large surface water features such as rivers and estuaries is universally under-informed at the long reach to basin scales (tens of km+). This challenge inhibits the accurate...

McCobb T, Briggs M, LeBlanc D, Day-Lewis F, Johnson C
J Environ Manage . 2018 May; 220:233-245. PMID: 29783177
Identifying and quantifying groundwater exchange is critical when considering contaminant fate and transport at the groundwater/surface-water interface. In this paper, areally distributed temperature and point seepage measurements are used to...
