Abstract
We analyzed and discussed bathing water quality at 11 official bathing sites in Kaštela (Croatia)
in the period 2009-2022. The results showed spatial and temporal variations in quality. The worst
bathing water quality was in the eastern part of the area, at beaches Torac, Kamp and Gojača. Levels
of indicator microorganisms at identified sources of fecal pollution near these beaches indicate a
significant load of fecal material to these areas. The observed decrease in annual fecal indicator
bacteria exceedances, while not statistically significant, indicates a trend toward improvement in
water quality. The number of sites with worse annual and final assessment showed a decreasing
trend only since 2017 and 2020, respectively, which is not a ‘sufficient’ time period to draw a clear
conclusion about the trend. The improvements are probably the result of intensive work in recent
years to improve the sewage system in the area. In the annual and final assessment, bathing sites from
Kaštela with ‘poor’ water quality accounted on average for more than 27% of all waters with ‘poor’ quality
in Croatia. This implies that additional efforts are needed to eliminate the sources of fecal pollution in the area.
