Nitrate is one of the most important parameters
in assessing surface and ground water quality.
Nitrates are naturally present in surface and
ground waters in low concentrations, but are
harmful to humans and livestock and cause aquatic
ecosystem degradation in high concentrations.
Nitrates enter the environment as human-induced
pollution from a variety of sources, but the largest
source is from agricultural fertilizer runoff . Other
sources include wastewater treatment discharge,
septic systems, and from pet waste. Nitrate is
highly soluble in water and therefore readily
leaches into water sources, whereas other human associated pollutants, such as phosphates and
ammonia, are not transported as easily. This ability to be quickly transported into ground and natural
waters such as drinking water wells, aquifers, reservoirs, lakes, and streams, coupled with its health
and environmental implications make nitrate pollution and monitoring of major concern.
