In the control of pathogens removal in W.S.P. in Portugal, other indicators than the classic ones were used to quantify die-off kinetics (Faecal coliforms, Faecal Streptococci, Clostridiumperfringens, Pseudomonasaeruginosa and Heterotrophies).

The influence of climatic parameters (temperature, precipitation, solar radiation) in that kinetics was studied, different equations being tested to express relationships existing among climatic parameters and microbial removal in different types of ponds.

The existence of significant correlations among these factors and parameters was concluded, as well as the dominance of certain models to quantify these relationships, differing according to the microorganisms considered, the type of lagoon and the climatic factor (θ) studied.
