The USEPA recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments. Total ammonia levels, at this limit, can range from 160 ppm at pH 6 and temperature of 5 degrees C to 0.06 ppm at pH 9 and temperature of 25 degrees C.he USEPA recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments.

Ammonia solutions decrease in density as the concentration of dissolved ammonia increases. At 15.6 Â°C (60.1 Â°F), the density of a saturated solution is 0.88 g/ml and contains 35% ammonia by mass, 308 g/l w/v, (308 grams of ammonia per litre of solution) and has a molarity of approximately 18 mol Lâ1.
