Sažetak
We tested the validity of the traditional hypothesis of a causal effect between rainfall occurrence, groundwater discharging into the sea, and marine microbial contamination. For groundwater characterisation we used the 18O isotope. Stable isotope 18O of water is a physical, naturally occurring environmental tracer. Its usefulness as tracer in hydrology has repeatedly been demonstrated, especially in karst regions such as the Adriatic Sea coastal belt. We tested the approach on locations in Bakar Bay and selected adjacent Rijeka city beaches. To test for statistical associations, we used the Panel Data Pairwise Granger Causality test. At examined locations, we found statistically significant relationships between the amount of rainfall and the abundance of 18O isotope in groundwater, as well as relationships between the abundance of 18O isotope in groundwater and faecal bacteria concentrations. Accordingly, 18O isotope, when used as an indicator for the functioning of karstic groundwater systems, may also be used as predictor of faecal contamination of bathing waters in associated karst littoral areas. We believe this physical method could be a valuable addition to present methods of predicting microbiological contamination and economic allocation of stock and flow pollutants in scarce common pool resources such as fresh water basins, springs and beaches.
