Exploring Sulfate Sources and Transport Across and Land Use Gradient in the Piedmont

The Clean Air Act Amendment in 1990 has been successful in limiting sulfate atmospheric deposition, but sulfate stream concentrations remain high, particularly in unglaciated regions.  There are several anthropogenic sources of stream sulfate, including building materials, road salt, septic systems, and agriculture. Beyond acidification, sulfate fluxes have ecological consequences for nutrient cycling through mobilizing phosphate. […]

Oregon Avenue Watershed Green Streets

The Oregon Avenue Watershed Green Streets (OAWGS) project was part of the District Department of Transportation’s (DDOT’s) efforts to address requirements for stormwater retention in accordance with its MS4 permit issued by the Environmental Protection Agency (EPA). DDOT and its consultant team developed the OAWGS project to reduce runoff from streets within the 360-acre Oregon […]

2021 Update-Phase III of the Chesapeake Bay Watershed Implementation Plan, Agricultural Sector Goals and Actions Part II

As a continuation to 2021 UPDATE-PHASE iii OF THE CHESAPEAKE BAY WATERSHED IMPLEMENTATION PLAN, AGRICULTURAL SECTOR GOALS AND ACTIONS – PART I we will review the direction that the Virginia Agricultural Cost Share (VACS) program has taken to achieve our WIP III goals. The WIP III requirements include structures designed to manage concentrated animal waste. […]

2021 Update-Phase III of the Chesapeake Bay Watershed Implementation Plan, Agricultural Sector Goals and Actions Part 1

One year after sediment and nutrient reduction goals were finalized, Virginia’s agricultural sector is working hard to meet these goals.  This presentation will provide an update to agricultural sector goals and what the Department of Conservation and Recreation, in partnership with Soil and Water Conservation Districts and the USDA-Natural Resources Conservation Service, is doing to […]

Everything in Life Must Have Balance…Including Water Quality and Quantity

Virginia Beach, is experiencing more frequent flooding due to sea level rise, increased storm intensity, and aging infrastructure. These issues coupled with tidal impacts and low elevations has resulted in severe flooding in portions of the City. Hurricane Matthew (2016) resulted in the worst structural flooding ever experienced.  As a result, the City embarked upon […]

An Interdisciplinary Approach for Determining Efficacy of Agricultural Best Management Practices

Despite increasing numbers of agricultural best management practices (BMPs) on the landscape and billions of dollars spent on BMP programs, stream health continues to decline in Virginia due to agricultural nonpoint-source pollution. The efficacy of BMPs for restoring stream health is potentially enhanced or constrained by conditions in the stream and watershed, as well as […]

Problem to Product: Evaluating the Use of Stormwater Pond Algae to Bioremediate Ponds and Generate Compost

While stormwater ponds are an effective best management practice for reducing stormwater runoff, often the algae that accumulates in them is considered a nuisance. Traditional treatments such as copper-based algaecides are not environmentally friendly, and other methods of removal can be costly and time consuming. Additionally, algae has a high capacity to remove contaminants from […]

Potential Impacts of Shared-Use Facilities on Conservation Programs

Numerous programs exist for farms to integrate conservation into their existing production framework to increase water quality and soil conservation while providing technical support and financial incentives for farmers to succeed. Yet despite these incentives, farmers often do not adopt these conservation practices for a variety of social, cultural, informational, and financial reasons. Thus, finding creative and informed ways of increasing adoption […]

Epilimnetic Mixing Deepens Maximum Phytoplankton Biomass and Reduces Phytoplankton Biodiversity in a Eutrophic Reservoir

Phytoplankton are primary producers which are critical for reservoir ecosystem function. However, certain phytoplankton, particularly cyanobacteria, can form noxious blooms in freshwater ecosystems. Epilimnetic mixing is a management strategy intended to disrupt surface scums of harmful cyanobacteria while promoting less-harmful phytoplankton taxa, such as diatoms. Many studies have examined the degree to which epilimnetic mixing […]

Environmental Services Strategic Plan Development and Implementation

The role of the eight coastal planning district and regional commissions (PDCs/RCs) in regional environmental services has been growing with increased support from federal programs to provide technical assistance to member localities. The Virginia Department of Environmental Quality, administering federal funds for coastal zone management and water quality improvement programs, asks PDCs to prepare scopes […]
