Checking Air Quality
You can check your neighbourhood's air quality through online platforms such as AirNow.gov, which provides an interactive map with data for air quality monitors in the US, Canada, and Mexico. The map includes a Fire and Smoke Map feature that shows how wildfire smoke may be impacting the air quality in your area. Each data point on the map represents a city or reporting area that issues a forecast, allowing you to assess the overall Air Quality Index (AQI) for your location.
Improving Air Quality
There are several ways to improve the air quality in your neighbourhood, both indoors and outdoors.
Indoor Air Quality
To improve indoor air quality, the US EPA recommends three basic strategies:
- Eliminate individual sources of pollution or reduce their emissions. For example, seal or enclose sources of asbestos, and adjust gas stoves to decrease emissions.
- Increase ventilation to remove or dilute indoor airborne pollutants. This can be achieved through natural ventilation, such as opening windows and doors, or mechanical means, such as a heating, ventilation, and air conditioning (HVAC) system.
- Introduce more outdoor air into your home. Most residential forced air-heating and air-conditioning systems do not mechanically bring outdoor air inside, so infiltration and natural ventilation are important.
Outdoor Air Quality
To improve outdoor air quality in your neighbourhood, consider the following:
- Use public transportation, walk, or cycle instead of driving your own car. This helps reduce congestion and air pollution, and can also improve your health.
- Advocate for better air quality data and clean air actions by writing to politicians, city councils, and government offices. Show your interest in improving air quality and inquire about participating in initiatives like Urban Innovative Actions.
- Install a green roof, which is a vegetative layer grown on rooftops. Green roofs can purify the air, reduce ambient noise, provide insulation, and protect your home from heat in the summer.
- Install solar panels on your roof to power your home with clean, renewable energy, and consider changing to an energy supplier that uses renewable sources like sun, wind, and water.
- Volunteer to host an air quality sensor on your premises to provide valuable data for governments and citizens to make informed decisions about improving air quality.
By taking individual and collective actions, we can actively contribute to improving the air quality in our neighbourhoods and creating a healthier environment for all.

Water quality
One way to assess the water quality in your neighbourhood is to refer to the "How's My Waterway" platform provided by the US Environmental Protection Agency (EPA). This platform offers the public information about the state of their local waters based on data collected from various sources, including state and federal agencies. The water quality information is presented on three scales: community, state, and national. It covers a range of topics, such as swimming, eating fish, aquatic life, restoration efforts, permitted discharges, impairments, local drinking water, and water monitoring. However, it is important to note that more recent or detailed water quality information may exist that is not yet available on the EPA databases.
Another concern regarding water quality is the presence of contaminants in drinking water. Organisations like the EWG highlight the issue of chemical contaminants in tap water for many Americans. They advocate for improved drinking water standards and provide resources to help individuals reduce their exposure to contaminants, such as guides to top-rated filters. Access to information about the contaminants in your local drinking water is crucial for making informed decisions and taking appropriate measures to protect your health.
Additionally, local government websites and reports can be valuable sources of information regarding water quality in your neighbourhood. They often provide data and updates on the condition of local water sources, any identified issues, and ongoing restoration or protection efforts. It is worth checking your local government's website or contacting them directly to inquire about water quality data specific to your neighbourhood.

Soil quality
One common way to test soil quality is to collect samples and send them to a laboratory, such as your nearest USDA extension program or a private company. This method can be relatively expensive, with costs varying based on location and the specific tests conducted. When collecting samples, it is important to create a map and record the exact locations from which each sample is taken. Surface growth should be removed, and a clean tool should be used to collect soil from a depth of at least 12 inches.
There are also several DIY methods for assessing soil quality that can be performed at home. One simple test is to dig a hole about 6 to 10 inches deep in damp soil and observe the structure of the soil. Healthy soil will consist of different-sized aggregates or chunks that retain their shape under slight pressure. Rich, organic soil often has rounder aggregates, facilitating better water and air movement around plant roots.
Another DIY test is to examine the soil's colour. Typically, nutrient-rich soil has a dark brown to black hue. However, it is important to note that soil colour can vary depending on the minerals and organic matter present.
Additionally, the presence of earthworms can be indicative of soil health. Digging a hole about 1 cubic foot deep and counting the number of earthworms can be informative. Healthy soil should contain at least 10 earthworms, as they contribute to nutrient-rich soil and better aeration.
It is worth mentioning that these DIY tests provide a general assessment of soil health. For more comprehensive information, sending samples to a laboratory for professional testing is recommended.
If your soil is contaminated, there are several options to consider. Mixing the soil with compost can help dilute contaminants, although this approach depends on the level of contamination. Creating a raised-bed garden with a landscape cloth at the bottom can prevent plant roots from coming into contact with contaminated soil. Alternatively, investing in containers and fresh soil, or joining a community garden, can be viable options.

Radon gas
Radon is a naturally occurring, colorless, odorless, radioactive gas that can seep into homes and buildings. It is created when natural radioactive uranium slowly decays in the ground and seeps to the surface. Radon gas can enter buildings through building materials made from natural substances, such as concrete, wallboard, and granite countertops, as well as water, especially from underground wells. The gas can become trapped indoors, and high levels of radon can lead to serious health issues over time, including lung cancer.
The US Environmental Protection Agency (EPA) estimates that one in every 15 American homes has radon levels above the recommended safety level. Similarly, in the UK, areas like Cornwall have some of the highest radon levels in the country. However, instances of lung cancer associated with radon are among the lowest in the UK, which is a bit of a mismatch.
Testing is the only way to determine if your home or neighborhood is affected by radon. Radon levels can fluctuate with changing seasons and weather conditions, so it is recommended to test multiple times throughout the year. There are radon maps available that can give you an idea of whether your area is likely to be affected by high radon levels. Additionally, you can place plastic detectors in your living room and bedroom for three months and then send them for testing to calculate your radon level.
If high levels of radon are detected in your home or neighborhood, there are effective mitigation measures that can lower radon levels to acceptable limits. These include simple building works, such as replacing or adding ventilation bricks in outside walls or installing a small pump in the loft to improve airflow.

Industrial pollution
Air pollution is caused by various industrial sources, such as fracking, steel-making plants, petrochemical plants, and hazardous waste sites. Natural gas, plastic, chemical, electric generation, and waste disposal industries can also generate hazardous waste, which, if not properly disposed of, can create significant air pollution. The Clean Air Act of 1963 in the United States aimed to address airborne pollutants, and subsequent amendments have expanded its scope to include issues like ozone depletion and acid rain.
Water pollution from industrial sources is also a significant concern. Industrial waste or pollutants are generated from manufacturing or industrial processes, and the rapid production growth has increased the volume of wastewater discharged into water bodies. Solid and liquid industrial wastes are released into watercourses, disrupting marine life and degrading water quality. The Clean Water Act (CWA) was introduced in 1972 to prevent water pollution sources and restore the nation's waters.
In addition to air and water pollution, industrial activities can also contaminate land. Legacy pollution refers to the long-lasting pollution of sediment, which is challenging to remedy. One approach is to store the polluted sediment in enclosures for long-term storage, but this does not address the underlying contamination.
To address industrial pollution, there is a need for comprehensive waste treatment strategies that aim to eliminate priority pollutants at their source. This can be achieved by utilizing indigenous microorganisms that can indicate pollution and detoxify polluted wastewater. Additionally, organizations like the Clean Air Council work to prevent hazardous industrial waste and advocate for testing to identify pollutants of concern.
To determine if your neighborhood is affected by industrial pollution, you can utilize resources such as the Environmental Protection Agency (EPA)'s Toxics Release Inventory, which tracks pollution from industrial facilities. Websites like AirNow.gov provide real-time air quality data, and you can also refer to water quality databases to assess the safety of your drinking water.
