Nitrates in the Conodoguinet Creek
Conodoguinet Creek
Conodoguinet comes from an Indian word meaning "A long way with many bends". The creek was rightly named this for its twisting and bending path. The Conodoguinet Creek is approximately 90 miles long and flows east into the Susquehanna River. The creek drains an area of 470 sq miles that is occupied by both agricultural and developed land.
There are 33 permitted point source discharges into the Conodoguinet Creek. Water tested from wells in Cumberland county and in the Carlisle area near the Condoguinet Creek have nitrate concentrations that are among the highest in the nation, frequently exceeding 10 mg/L.
Nitrates
What are nitrates?:
Nitrates are Nitrogen-Oxygen chemical units. The primary sources of organic nitrates come from human sewage and livestock manure. The primary inorganic sources of nitrates are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. Nitrates migrate to ground water which is often used as utility or drinking water. They do not evaporate naturally in water. The only way nitrates can be removed from water is if they are consumed by living organisms or treated at a water treatment center.
Health Effects of Nitrates
Short-term and Long-term exposure can cause serious health effects to humans and the environment. Standards and regulations have been set by the Environmental Protection Agency (EPA).
