Environmental testing refers to the process of analyzing air, water, soil, and other environmental samples to assess their quality and safety. This testing helps identify pollutants, contaminants, and other harmful substances that can affect human health and ecosystems. Common methods include laboratory analysis and field sampling. The results of environmental testing are crucial for regulatory compliance and public health. Organizations often conduct these tests to ensure that industrial activities, waste disposal, and other practices do not harm the environment. Regulatory bodies, such as the Environmental Protection Agency (EPA), set guidelines and standards for acceptable levels of various substances.
