Question

Quizplus · Accepted Answer

The main sources of lead, mercury, and arsenic water pollutants are unlined landfills, household chemicals, mining refuse, and industrial discharges. These pollutants are often found in waste products from various industries and can contaminate nearby water sources. Electric power plants (A) can also be a source of water pollution, but they tend to emit different types of pollutants such as sulfur dioxide and nitrogen oxides. Sewage and inorganic fertilizers (C) can contribute to nutrient pollution, but they do not typically contain lead, mercury, or arsenic. Runoff from streets and parking lots (D) can carry pollutants such as oils, salts, and metals, but again, these are not typically the main sources of lead, mercury, and arsenic. Land erosion from farms that have used chemical insecticides (E) can contribute to soil erosion and pesticide runoff, but again, these are not typically the main sources of these specific water pollutants.
