It includes monitoring pool and bathing beach water to assure their safety. It also includes testing the ocean, bays, lakes, rivers and streams for pollutants and nutrients that can damage fauna, flora, and appearance. The PEHL analyzes samples of ambient air and the air from soil located above petroleum spills for toxic, organic and inorganic substances.
