The studies aimed at sanitary evaluation of two small lakes situated in the city of Szczecin, Poland:
Rusaka and Syrenie Stawy. The studies were performed in summer months (June to August) in 1995-1996
and 1998-1999. In water samples, total coliforms, faecal coliforms, faecal streptococci and pollution-indicative
index bacteria (TVC 20oC, TVC 37oC) were estimated. The analyses demonstrated that Rusaka
lake exhibited lower levels of pollution than that shown by Syrenie Stawy. Also, the obtained results demonstrated
in general higher level of pollution than that noted by other authors in municipal lakes.
