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 is a nutrient that contains nitrogen and hydrogen. Its chemical formula is NH 3 in the un-ionized state and NH 4+ in the ionized form. Total ammonia is the sum of both NH 3 and NH 4+ .Total ammonia is what is measured analytically in water.mmonia can be converted to nitrite (NO 2) and nitrate (NO 3) by bacteria, and then used by plants. Nitrate and ammonia are the most common forms of nitrogen in aquatic systems. Nitrate predominates in unpolluted waters.
