Paints often contain toxins and pollutants that can seep into groundwaters if not disposed of properly. Most communities have special toxic round-up days when they accept batteries, paints, and other toxic chemicals.
Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.. that emit fluids of varying quality directly into urban water supplies. In the United States and other countries, these practices are regulated, although this doesn't mean that pollutants can't be found in these waters. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere via rain water. Soils and groundwaters contain the residue of human agricultural practices (fertilizers, pesticides, etc..) and improperly disposed of industrial wastes. Atmospheric contaminants are also derived from human practices (such as gaseous emissions

The three classifications of sources of information are primary sources, secondary sources, and tertiary sources. Primary sources offer firsthand accounts or original data, secondary sources analyze and interpret primary sources, and tertiary sources provide summaries and overviews of information from primary and secondary sources.
