The Clean Water Act references the Toxic Pollutant List at section 307 (a) (1); 33 U.S.C. 1317 (a) (1). The list appears in the Code of Federal Regulations at 40 CFR 401.15.

Here are some of the most terrifying toxins that pervade America's water supply. Lead poisoning was at the heart of the Flint crisis, but it's also a problem in places like Detroit, Pittsburgh, and Washington, DC. A water collection device handed to the citizens of Flint in 2016.
The Toxic Pollutant List was developed in 1976 and subsequently added to the Clean Water Act by Congress in 1977.
Chlorine. Chlorine is a powerful oxidant added to the water by several municipal water systems to control microbes. Chlorine can be absorbed through physical consumption as well as through your skin while bathing.

Richard Fuller (RF): Toxic pollution is contaminated water, soil, and air that is harmful or poisonous. It includes industrial wastes like toxic heavy metals from mining or chemicals from factories, and also sewage and particulates from power plants.

All in all, mercury is one of the most deadly toxic pollutants in the air. Not only is Sulfur Dioxide (SO2) a substantial pollutant in our air and a direct result of coal power plants, it is also one of the causes of some serious health problems. It can be a root cause of lung cancer, asthma, emphysema, and bronchitis.
What Are Toxic Air Pollutants? Toxic, or hazardous, air pollutants cause or are suspected of causing cancer, birth defects, or other serious harms. They can be gases, like hydrogen chloride, benzene or toluene, dioxin, or compounds like asbestos, or elements such as cadmium, mercury, and chromium.
The Pollutants Examples of toxic air pollutants include benzene, which is found in gasoline; perchlorethlyene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries.
run-off from agricultural land containing substances including pest control products, animal medicines, slurry, sewage sludge and manure. run-off and leaching from contaminated land. silt and dust from mining, quarrying, construction and demolition. groundwater drainage discharging from disused mines.
Main causes of water pollution are: Untreated sewage. Industrial wastes. Fertilizers and pesticides.
Chemical contaminants are elements or compounds. These contaminants may be naturally occurring or man-made. Examples of chemical contaminants include nitrogen, bleach, salts, pesticides, metals, toxins produced by bacteria, and human or animal drugs.
The Toxic Pollutant List was developed in 1976 and subsequently added to the Clean Water Act by Congress in 1977. The list was intended to be used by EPA and states as a starting point to ensure that Effluent Guidelines regulations, water quality criteria and standards, and NPDES permit requirements addressed the problems of toxics in waterways.
Starting with the list of toxic pollutants, EPA used four criteria to select and prioritize specific pollutants: We included all pollutants specifically named on the list of toxic pollutants; There had to be a chemical standard available for the pollutant, so that testing for the pollutant could be performed;
The Priority Pollutants are a set of chemical pollutants EPA regulates, and for which EPA has published analytical test methods . The Priority Pollutant List makes the list of toxic pollutants more usable, in a practical way, for the purposes assigned to EPA by the Clean Water Act. For example, the Priority Pollutant list is more practical ...
Originally, there were 129. When three pollutants were removed from the list of toxic pollutants in 1981 (see " Modifications " above), they were also removed from the Priority Pollutant List.
De-listing the three pollutants did not change the 65 entries because the three de-listed pollutants were specific compounds within entries for the groups Halomethanes (list entry 38) and Haloethers (list entry 37).
For the 14 states that did not timely adopt such numeric criteria, EPA promulgated the National Toxics Rule (NTR) on December 22, 1992 (57 FR 60848). The NTR uses the criteria listed in section 304 (a) to promulgate numeric criteria for states that had not yet adopted numeric criteria for those toxic pollutants.
Therefore, EPA developed the Priority Pollutant List in 1977 to make implementation of the Toxic Pollutant List more practical for water testing and regulatory purposes. Portions of both lists are outdated.
