Quizplus · Accepted Answer

Unlined landfills, household chemicals, mining refuse and industrial discharges are the main sources of lead, mercury and arsenic water pollutants. These pollutants leach into groundwater and surface water, contaminating them and posing a risk to human health and the environment. Other sources mentioned in the other options (electric power plants, sewage and inorganic fertilizers, runoff from streets and parking lots, land erosion from farms that have used chemical insecticides) may contribute to water pollution, but they are not the main sources of these specific pollutants.
