Environmental testing refers to the process of analyzing and assessing the quality of the environment, including air, water, soil, and other natural resources. This testing helps identify pollutants, contaminants, and other harmful substances that may affect ecosystems and human health. It is essential for ensuring compliance with environmental regulations and for protecting public safety. Various methods and techniques are used in environmental testing, such as sampling, laboratory analysis, and field measurements. Organizations like the Environmental Protection Agency (EPA) often oversee these tests to ensure accurate results and promote sustainable practices. The data collected can inform policy decisions and environmental management strategies.
