Description

This lab analysis measures Nitrate (as N), Ammonia, and Total Kjeldahl Nitrogen (TKN)—key indicators of nitrogen dynamics in a lake. Together, these parameters provide insight into how nitrogen is entering, transforming, and accumulating in the system, helping to characterize overall nutrient conditions and biological activity. 

  • Nitrate (as N):  Methodology: EPA 300.0  MDL: 0.01 PPM  RL: 0.1 PPM    
  • Ammonia:  Methodology: EPA 350.1  MDL: 0.04 PPM  RL: 0.05 PPM  
  • Total Kjeldahl Nitrogen (TKN): Methodology: EPA 351.2  MDL: 0.15 PPM  RL: 0.02 PPM   

What problem does this solve?

Testing for nitrate, ammonia, and TKN helps identify whether nitrogen is contributing to water quality issues in your lake. Elevated nitrogen levels can fuel algae growth, increase the risk of harmful algal blooms, and contribute to oxygen depletion—especially when ammonia levels are high or nitrogen inputs are ongoing.

Regular monitoring allows lake associations, homeowners, and lake managers to track nitrogen sources and trends over time, assess impacts from runoff, septic systems, or internal recycling, and make informed decisions about preventative actions, watershed controls, or the need for further monitoring or treatment.
