Popis:	The nature, occurrence and analysis of water pollutants is interesting chemically and relates well to the interdisciplinary nature of the modern chemistry curriculum. The issue is of worldwide significance and affects both wealthy and poor nations. In the first part of this paper we present an overview of water pollution in the United States and Mexico, including sources, federal regulations and standards, and standard methods for the assessment of overall water quality. The second part of the paper focuses on three water pollutants, lead, atrazine, and nitrate. We chose these as important representative examples of heavy metals, organic herbicides and inorganic pollutants. In addition to a background discussion of each substance and analysis methods for it, we describe laboratory activities that are suitable for the high school audience.
