This study is focused on the microbiological quality of a sandy beach in the coastal area around Rome, Italy. The microbiological surveys were carried out on the sands collected both on the beach and on the waterline. A low-concentration of faecal bacteria (streptococci outnumbered Escherichia coli) and a constant rate of staphylococci were detected over the sampling period. Significant statistical correlations were calculated between yeasts and moulds, Escherichia coli and streptococci, streptococci and sulfite-reducing clostridium spores. This survey's data could be a baseline for future studies.
