What is Ammonium/Ammonia? Ammonium (NH4+) is a positively charged ion (or cation) that is formed by the addition of a hydrogen proton to ammonia (NH3). Ammonia is found naturally in water, but if it is found at higher than natural levels this is a sign of contamination. Ammonia levels higher than around mg/L usually indicate polluted waters.
