Virginia has a pollution problem. The state ranks 20th in the nation for air quality and is the second-worst state for toxic chemicals dumped into its waterways. Sources of air pollution in Virginia include power plants, automobiles, construction sites, and road repair areas. As for water pollution, industrial facilities, farms, and urbanisation are the main culprits. This has contaminated Virginia's rivers, streams, and drinking water with toxic chemicals, heavy metals, and bacteria.

Automobile emissions
Ground-level ozone, which is the main ingredient in smog, is formed by the reaction of sunlight with vehicle emissions, gasoline fumes, solvent vapors, and power plant and industrial emissions. Automobile emissions are also a source of volatile organic compounds (VOCs) and ammonia, which are not criteria pollutants but contribute to their formation and are therefore regulated and tracked by the Virginia Department of Environmental Quality (DEQ).
The DEQ is responsible for monitoring air pollution at various locations throughout Virginia and works with federal and state authorities to promote clean air and enforce air quality regulations. The department issues air quality permits, monitors and analyzes air quality data, and provides daily Air Quality Forecasts and Health Alert Notifications to help individuals plan their activities during periods of high pollution.
To improve air quality and reduce automobile emissions, Virginia can focus on increasing the efficiency of automobile engines, promoting the use of hybrid vehicles, and encouraging alternative modes of transportation. These measures will not only improve air quality but also help reduce greenhouse gas emissions, contributing to the fight against climate change.
While automobile emissions are a significant source of pollution in Virginia, it is important to note that other sources, such as power plants, industrial facilities, and construction sites, also contribute to the state's air and water pollution levels.

Industrial facilities
The New River, for instance, experienced the highest level of toxic pollution in Virginia, with over 12 million pounds of toxic chemicals discharged into its waters. Richmond's James River also saw over 1.1 million pounds of toxic pollution in 2010, while the Shenandoah River received 377,090 pounds of toxic pollution in the same year. These toxic chemicals, including arsenic, mercury, and benzene, pose serious risks to both environmental and human health. Exposure to these pollutants has been linked to cancer, developmental disorders, and reproductive issues.
The Clean Water Act, enacted in 1972, aimed to address industrial water pollution. However, recent Supreme Court decisions have called into question the Act's jurisdiction over Virginia's streams and drinking water sources. Environment Virginia has recommended several strategies to curb toxic pollution, including reducing toxic discharges, finalizing guidelines to protect all waterways, and implementing tougher permitting and enforcement measures.
In addition to water pollution, industrial facilities also contribute to air pollution in Virginia. The Virginia Department of Environmental Quality (DEQ) monitors air pollution levels throughout the state, including emissions from industrial sources. While emissions of criteria pollutants from point sources, such as power plants and factories, have decreased over the years, industrial emissions still play a role in the overall air quality of the state.
To improve air quality and reduce the impact of industrial facilities on the environment, Virginia can focus on transitioning to cleaner energy sources for electricity generation and encouraging the use of alternative modes of transportation. By reducing the reliance on coal-burning plants and promoting energy efficiency, Virginia can mitigate the pollution caused by industrial facilities and improve the health and well-being of its residents.

Construction sites
Air Pollution from Construction Sites
Water Pollution from Construction Sites
Construction activities are a major source of nonpoint source (NPS) pollution in Virginia's waterways. NPS pollution occurs when rainwater washes pollutants from various sources into streams, rivers, and other bodies of water. Construction sites contribute to NPS pollution through soil erosion, releasing sediments, and the runoff of harmful substances such as toxins, excess nutrients, and pathogens.
Sediment from construction sites is the largest pollutant by volume in Virginia's waterways. The eroded sediment smothers underwater habitats, clogs fish gills, and blocks sunlight, negatively impacting aquatic plants and animals. Additionally, the runoff of toxins and excess nutrients from construction sites can lead to uncontrolled algae growth, further degrading water quality and harming aquatic ecosystems.
Regulatory Efforts and Improvements
Virginia has implemented several measures to address pollution from construction sites and other sources. The state's Department of Environmental Quality (DEQ) plays a crucial role in monitoring and improving air and water quality. The DEQ issues permits, analyzes data, and works with authorities to enforce air quality regulations.
Virginia's Nonpoint Source Pollution (NPS) Management Plan, updated every five years, provides guidance and funding for controlling NPS pollution. The state has also made efforts to reduce air pollution by closing coal-powered plants and improving air quality in mountain regions. As a result, Virginia's overall air quality ranks 20th best in the nation, with improvements in smog and air particulate levels.

Power plants
In 2023, natural gas accounted for 55% of Virginia's electricity generation, while coal contributed 2%. The state's largest power plant, the Bath County Pumped Storage Station, is a hydroelectric plant with a net generating capacity of 3,015 megawatts.
Virginia has taken steps to transition to cleaner energy sources. The Virginia Clean Economy Act of 2020 aims to achieve 100% renewable energy by 2045 by constructing more solar and wind power sources. Most coal-fired plants are planned to be closed by 2024, with only two allowed to operate until 2045.
The Virginia Department of Environmental Quality plays a crucial role in regulating and monitoring air quality, issuing permits, and enforcing regulations to reduce emissions and improve air quality in the state.

Farms
Air Pollution
Water Pollution
Water pollution from farms in Virginia is primarily through non-point source pollution, where rainwater washes pollutants from farmland into nearby waterways. This form of pollution is challenging to manage as it does not meet the legal definition of "point source" pollution outlined in the Clean Water Act. Farms contribute to water pollution through the use of pesticides, fertilizers, and manure, which can contaminate streams, rivers, and other water bodies. Excessive amounts of nitrogen and phosphorus from these sources can deplete oxygen levels in water, creating "dead zones" where aquatic life cannot survive.
Additionally, farming practices can increase erosion, leading to higher levels of sediment in nearby waterways. Sediment is the greatest pollutant by volume and can smother underwater habitats, clog fish gills, and block sunlight for aquatic plants.
Virginia has implemented measures to address non-point source pollution, including the Nonpoint Source Pollution (NPS) Management Plan, which is updated every five years and provides guidance for federal, state, and local actions. The state also promotes watershed planning, stream restoration, and education initiatives to reduce and prevent this type of pollution.
Sewage Sludge Contamination
Virginia farmers have also discovered PFAS contamination in sewage sludge used as fertilizer, posing risks to farms and local communities. PFAS contamination has been identified as a concern by the Virginia Conservation Network, with efforts to regulate and control this type of pollution.
