The Environmental Protection Agency (EPA) is an agency of the U.S. government established to enforce federal pollution abatement laws and implement various pollution prevention programs. The EPA regulates various environmental aspects, including air and water quality, waste management, pesticide usage, and industrial pollution.
Parts Per Billion (PPB) measures the concentration of a contaminant within a specific volume, expressed as the number of molecules of the contaminant per billion molecules of the total volume. It is a crucial metric used to ensure safety and compliance with environmental regulations.
Parts Per Million (PPM) is a unit used to measure the concentration of a substance in a mixture or solution, often used in environmental science, chemistry, and real estate for analyzing air, water, and soil contamination levels.
