This paper presents results of bacteriological investigations concerning coastal seawater and sandy sediments in the Three-city region at the outlet of four streams: Kacza (KaS), Swelina (SwS), Grodowy (GS) and Kamienny (KmS). The numbers of facultative psychrophilic bacteria, mesophilic bacteria and indicator bacteria (coliforms, fecal coliforms, fecal enterococci) were determined. It was found that all streams are carrying fecal bacteriological pollution of human and animal origin which contributes to poor quality of coastal seawater and sandy sediments. The lowest sanitary quality was KaS water, where the number of all indicator bacteria, as a rule, exceeded admissible levels. In sandy sediments of the estuaries of all four streams the average number of indicator bacteria was about one order of magnitude higher than in water. Enterococcus was the bacterial indicator that exceeded single water or sediment sample standards most often.

A number of indicatory microorganisms are found in clean and lightly polluted surface water in the ditch in Słupy village and in the drainage ditch in the region of Barczewo; in the Elżbieta Canal and in Wójtowo stream - for clean (TVC 37°C), lightly (TC, FC, and FS), or strongly (TVC 20°C) polluted surface water; and for inconsiderably or noticeably (TVC 20°C and TVC 37°C) and strongly (TC, FC, FS and Clostridium perfnngens) polluted surface waters, in the Orzechówka and Pisa Rivers. An inconsiderable amount of pollution by indicatory microorganisms is characteristic of the waters of Wadąg Lake and the Wadąg River, which flows from this reservoir. The greater amount of pollution by these microorganisms in the investigated watercourses occurs after rainfall in May and/or June, in September 1992, and after rain and thawing in the lake in January 1993.
