Water contaminants

  • Naturally occurring chemicals and minerals, such as arsenic, fluoride, iron and uranium, in the earth layer.
  • Local land use practices like fertilizers, pesticides, livestock, and concentrated feeding operations.
  • Contaminations can also be by manufacturing processes like heavy metals or cyanide near drinking water sources.
  • Water contamination also includes malfunctioning on-site wastewater treatment systems such as septic systems and twin pit toilets; microbial contamination through a mixture of wastewater in the drinking water source or distribution line.
  • Drinking water that is not properly treated or that travels through an improperly maintained distribution system, pipes, may also create conditions that increase risk of contamination.
