“One of the chief reasons for lagoon failures in the US are that most lagoons were built in the 60’s, 70’s, and 80’s before a sound understanding of lagoon hydraulics, biology and chemistry was available. Today with a greater understanding of these dynamics, changes can be made to overcome original design deficiencies for better effluent quality.”
