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 […]
The Campostella Landfill is in Norfolk, Virginia along Berkley Avenue and near the Steamboat Creek. It was constructed unlined on a wetland and accepted waste from 1944 to 1992 with no leachate collection system. Groundwater monitoring began in 1994, since 2001 on a semi-annual basis. Groundwater monitoring shows leachate-contaminated groundwater beneath the landfill with primary […]
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 […]
A flexible approach to meet ongoing local and Bay TMDL requirements is required to stay current with changing guidance and regulations, climate, and citizen needs. The recent modifications by DEQ to the calculation of street sweeping credits for meeting TMDL pollutant reduction goals have significantly reduced the pollutant removal credit for this compliance strategy, effective […]
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 […]
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 […]

Loudoun County’s Illicit Discharge Detection and Elimination (IDDE) program dates back almost 20 years. The County is one of the fastest growing communities in the Country, and its stormwater network of 3,000 outfalls is continually increasing. As the outfall inventory grows and land uses change, it is imperative that the County adjust its procedures to […]
Timmons Group is providing drainage and environmental improvement services to reduce water impacts and minimize safety concerns along a channel in Hampton, VA. The waterway currently flows through an old concrete channel that is in disrepair in several sections and is bordered with sites that have old concrete and construction debris buried. The City recognized […]
Anthropogenic activity is responsible for changing environmental conditions in many environments, including nutrient over-enrichment in lakes and coastal waters, and elevated temperatures and carbon dioxide concentrations in the atmosphere and water. Due to these changes, many lakes have become increasingly stratified and eutrophic. These factors create a perfect environment for the proliferation of cyanobacterial harmful […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
