Total Nitrogen

Total Nitrogen is a measurement of the sum of organic and inorganic nitrogen in a water body. Factors that introduce this nutrient into the environment include sewage and residential runoff, soil erosion, and organic decomposition. The state criteria for total nitrogen content in a healthy body of water should not exceed 0.25 mg/L. Most of the data collected from Enchanted Lakes gave figures that were far above state criteria, such as a level of 1.437 mg/L collected from site 2 on March 4, 2004. It is possible that heavy spring showers caused an overflow of nutrient rich untreated sewage, thereby boosting the total nitrogen level.
