Indoor air quality
The pollutants that impact indoor air quality include volatile organic compounds (VOCs), particulate matter (PM), carbon dioxide (CO2), and humidity levels. Particulate matter includes dust, tobacco smoke, diesel emissions, pollen, pet dander, and mold spores. These particles are so small that they can enter the lungs and even the bloodstream. Other sources of indoor pollution include burning fuel, which releases harmful emissions such as carbon monoxide and benzene. Appliances like cook stoves release these emissions directly into the home, while furnaces and water heaters typically vent them outdoors. Allergens such as pet dander, mouse and cockroach droppings, mold, and mildew also contribute to poor indoor air quality.
To improve indoor air quality, the general strategies are to eliminate or reduce the sources of pollution, improve ventilation, and clean the air. Opening doors and windows daily for at least 10 minutes can help improve air quality by allowing outdoor air to dilute indoor pollutants. However, this may not be advisable if you live near sources of outdoor air pollution or on poor air quality days. Instead, a portable mechanical HEPA air cleaner can be used to capture particulate matter, chemicals, and pollutants. Advanced designs for new homes are also incorporating mechanical systems that bring in outdoor air, including energy-efficient heat recovery ventilators.

Water quality
The United States Environmental Protection Agency (EPA) offers a valuable tool called "How's My Waterway." This platform provides the public with comprehensive information about the quality of their local waters. It utilizes data from states, federal and tribal agencies, and other sources to offer insights at the community, state, and national levels. "How's My Waterway" covers a range of topics, including swimming, fishing, aquatic life, restoration efforts, permitted dischargers, impairments, and local drinking water information.
Additionally, organizations like the New York State Department of Environmental Conservation (NYSDEC) work to protect water resources and ensure safe water quality. NYSDEC's activities include addressing climate change impacts, promoting responsible waste management, monitoring air quality, and overseeing contaminated site cleanups. They also engage in community outreach through newsletters, magazines, webinars, and environmental education sessions.
To further enhance water quality monitoring, NYSDEC adheres to specific regulations and standards. They receive funding from the NYS Environmental Protection Fund (EPF) and the federal Performance Partnership Grant (PPG), which supports their monitoring programs. NYSDEC also implements quality assurance thresholds for their water programs to ensure that the data collected meets acceptable standards for its intended use.
Water pollution and contamination are pressing issues, and it is crucial to take proactive measures to protect yourself and your family. Resources like EWG's Tap Water Database highlight the presence of contaminants in drinking water and offer guidance on effective filters to reduce these contaminants, thus safeguarding your health.
By staying informed, supporting initiatives for improved water quality standards, and taking individual actions, we can collectively work towards ensuring clean and safe water for our communities and the environment.

Toxics Release Inventory
The Toxics Release Inventory (TRI) is a resource for learning about toxic chemical releases and pollution prevention activities reported by industrial and federal facilities. TRI data supports informed decision-making by communities, government agencies, companies, and others. TRI tracks the management of over 650 toxic chemicals that pose a threat to human health and the environment. US facilities in certain industry sectors that manufacture, process, or otherwise use these chemicals in amounts above established levels must report how each chemical is managed through recycling, energy recovery, treatment, and releases to the environment. A "release" of a chemical means that it is emitted into the air or water or placed in some type of land disposal.
TRI information helps support informed decision-making by industry, government, non-governmental organizations, and the public. Note that TRI does not provide any safety or health information about these chemicals and compounds. TRI data, in conjunction with other information, can be used as a starting point in evaluating exposures that may result from industrial activities involving toxic chemicals.
TRI facilities are legally required to report to the EPA by July 1st of each year. Every year, the EPA also publishes documents and webpages that provide analysis and interpretation of the most recent TRI data, including national and local trends of toxic chemical releases into the environment. Geo-specific analyses include Indian Country and Alaskan Native Villages, large aquatic ecosystems, urban communities, and state fact sheets. TRI National Analysis documents are available online, and many are in Spanish.
TRI was first proposed in a 1985 New York Times op-ed piece written by David Sarokin and Warren Muir, researchers for an environmental group, Inform, Inc. Congress established TRI under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and later expanded it in the Pollution Prevention Act of 1990 (PPA). The law was developed out of concern about Union Carbide's releases of toxic gases in the 1984 Bhopal disaster (India) and a smaller 1985 release at its plant in Institute, West Virginia.
To check the pollution in your area, you can refer to websites such as WAQI.info, which provides a real-time air pollution map for more than 80 countries. The Air Quality Index is based on the measurement of particulate matter (PM2.5 and PM10), Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Carbon Monoxide (CO) emissions. Similarly, the UK government website provides information on air pollution levels across the UK.
