Stormwater runoff from urban areas is primary cause of flooding and erosion of urban streams, as well as a major source of pollution of receiving water bodies. Green stormwater infrastructure (GSI) is increasingly being employed as a stormwater management tool in urban areas, with the intent of using infiltration to address both water quantity and […]
Wastewater-based epidemiology is increasingly being viewed as a powerful tool for providing information about the health of a community because each person in a treatment plant’s service area inevitably contributes to the wastewater. Here, we partnered with two wastewater treatment plants in the Commonwealth of Pennsylvania – Derry Municipal Water Authority (WWTP A) and a […]
Successful restoration of the urbanized Delaware Estuary will provide great benefit to people and wildlife alike by improving ecosystem services. Although considerable progress has been made towards this goal of restoration, the estuary’s location at the center of complex urban, suburban, and agricultural land use makes this a challenge. In urban areas, one of the […]
Nonpoint sources of contaminants and nutrients have led to impairments of many water systems in the Delaware and Susquehanna watersheds. Stormwater management practices (SMPs) have been implemented to improvement both water quantity and water quality outcomes, and Green Stormwater Infrastructure (GSI), a stormwater management approach which is largely based on water retention and infiltration, is […]
Thousands of tons of plastic pollution end up in the Great Lakes every year having adverse effects on marine life and on water quality. Quantifying major sources and pathways of plastic pollution entering the Great Lakes can be highly valuable for developing suitable mitigation strategies. We propose a two yearlong study to quantify urban plastic […]
The primary focus of this project is to determine the distribution, prevalence, and genetic composition of non-native Salmincola spp. (commonly referred to as gill lice) and the potential impacts that Salmincola spp. are having on the Commonwealth’s wild trout populations. Of particular concern are the impacts of Salmincola spp. on Pennsylvania’s wild Brook Trout and […]
Overview Coastal wetlands of the Delaware River Estuary and much of North America are converting at a rapid pace to near-monocultures of the invasive lineage of the common reed Phragmites australis (hereafter Phragmites). Unfortunately, we know surprisingly little about how Phragmites invasion affects coastal blue carbon, specifically carbon (C) sequestration or soil C processes (e.g. […]
Tidal wetlands are important ecosystems that provide a number of ecosystem services such as nutrient transformation and removal, carbon sequestration, and habitat for fish and wildlife. Tinicum marsh in John Heinz National Wildlife Refuge is Pennsylvania’s largest and last remaining tidal wetlands. Tinicum is one of nine wetland monitoring sites within the Mid-Atlantic Coastal Wetland […]
Understanding and predicting fish community interactions and their responses to changes in the environment are critical to the conservation and management of Pennsylvania fish communities and to water resource management. However, quantifying and predicting the effects of environmental stressors on fish communities is made difficult by the complex interactions that exist between species and between […]
Flathead Catfish Pylodictis olivaris are an indiscriminate predator of other fish and an expanding invader to large river systems outside of its native range, including the Susquehanna River Basin in Pennsylvania. Research efforts are beginning to provide insight on the distribution of this invader in the Susquehanna River Basin, however, there is considerable uncertainty about […]
