Water Testing
110 Samples Collected

​Prevention is far better than remediation.

The NLPA consulted with experts within TDEC and UT to determine what four critical pollutant indicators that we should include in water quality testing.

​​

  1. Ammonia:  Elevated levels via direct means, such as municipal discharges, animal/human waste, and agricultural runoff. Normal range is 0.01-0.50 mg/L. Cause for immediate concern is 2.5

  1. ​​

  2. Nitrate: Major sources of nitrate contamination can be from fertilizers, animal waste, and human sewage. A nitrate-nitrogen normal range is 0.2-3.0 mg/L.

  3. Conductivity:  A measure of the ionic content (such as chloride, nitrate, sulfate, sodium, magnesium, calcium, or iron) in a body of water by measuring the water’s ability to conduct electricity; a large variance to a site's typical reading may mean that a pollution event has occurred.  Freshwater lakes typically have a range of 100 - 2,000. 

  4. pH:  Optimal pH level for fish ranges from 6.5 to 9.0. At levels outside this range, fish become susceptible to poisoning from toxic chemicals. Changes in pH can also cause an overload of available plant nutrients, resulting in excessive plant growth and depleted oxygen levels for fish.
