Table 2. LTIMP surface-water sample analysis; constituents, abbreviations, parameter codes, and reporting levels
[Total nitrogen = total organic plus ammonia nitrogen (TKN) plus dissolved nitrite plus nitrate (NO2 + NO3); soluble reactive phosphorus (SRP) = dissolved orthophosphate phosphorus. Abbreviations: mg/L, milligrams per liter; µg/L, micrograms per liter; °C, degrees Celsius; ft3/s, cubic feet per second; µS/cm, microsiemens per centimeter]
