Study of the Physiochemical and Microbial Properties of the Waters of the Seashore in the City of Tocra, Libya

The current study aimed to assess the state of water quality in Tocra beach (Libya). The physical, chemical, and bacterial properties of water were also studied. Water samples were collected from the sea and sediments for three consecutive months in the year (2020-2021) to study the following factors (water temperature, salinity, electrical conductivity, pH, total dissolved salts, chemical and biological requirements for oxygen, dissolved organic matter, and active nitrate). It was noted through these results that the proportions of these variables did not exceed the record numbers of seawater, in addition to the presence of contamination with the bacteria Escherichia coli (Negative gram) and it has proven its effectiveness for antibiotics, which indicates sewage pollution.
