Surface water, pore water, pond bottom sediments, and groundwater were sampled within and downgradient from five groundwater flow-through ponds that ranged from oligotrophic to eutrophic in Cape Cod, Massachusetts during different seasons from 2015 – 2018. The sampled ponds included Ashumet, Santuit, Snake, Shubael, and Longs. Pore water was collected between 15 to 100 cm below the pond bottoms on the upgradient and downgradient sides of the ponds. Groundwater was collected on the downgradient side where the pond water recharges the groundwater resulting in a “pond shadow”. Within the pond shadow, groundwater is under the direct influence of surface water. The pond shadows were sampled vertically and at various...

1. Riverbank Filtration (RBF) Microbiology: Determination of removal efficiencies of microbes within bank filtration sediments under varied geohydrologic conditions (sediment geology, organic/inorganic geochemistry and flow regime) using flow through, 2-D sand tank, and static minicolumns. 2. Compare RBF attenuation rates for pathogen surrogates (virus to oocyst-sized) to those of natural systems (outflow regions in lakes and ponds) using our previously published methods. These have important implications regarding groundwater under the direct influence of surface water (GUDI). One component involved assessing the subsurface mobility of non-toxic cyanobacteria, subsurface mobility of cyanobacteria and cyanophage...
