This lab analysis measures Nitrate (as N), Total Phosphorus (as P), and Total Kjeldahl Nitrogen (TKN). Together, these parameters serve as a reliable indicator of a lake’s nutrient status and potential for algae and plant growth. Results are reported in parts per million (PPM), helping you assess the overall nutrient loading and eutrophication risk in a lake. Nitrate (as N): Methodology: EPA 300.0 MDL: 0.01 PPM RL: 0.1 PPM Total Phosphorus: Methodology: EPA 365.1 MDL:0.008 PPM RL:0.01 PPM Total Kjeldahl Nitrogen (TKN): Methodology: EPA 351.2 MDL: 0.15 PPM RL: 0.02 PPM Show more
