“…Many bacterial species have been reported in groundwater with different antibiotic susceptibilites [8]. During bacterial infiltration through soil layers, different microbiogeochemical reactions and interactions can occur [9,10]. In groundwater as in river water, different interactions can lead to potential genetic mutations of microorganisms [11].…”

Little is known about the variation of the antibiotic susceptibility of different bacterial strains of the same cells species, isolated from different aquatic environments. The present study aims to evaluate the susceptibility towards some 3rd generation cephalosporins (Ceftriaxon, Ceftazidim and Cefotaxim) and Amoxicillin/Clavulanic acid, of Enterobacteriaceae strains isolated from groundwater, stream, hospital wastewater and slaughterhouse wastewater. Enterobacteria species were isolated on Mac Conkey agar, then identified using enzymatic and MALDI-TOF MS system. The antimicrobial susceptibility was carried out using the disk diffusion method. The antibiotic minimum inhibitory concentrations (MICs) were carried using the VITEK®2 system. Bacterial species mostly identified were Klebsiella pneumoniae, Escherichia coli, Salmonella typhi and Ewingelia americana. The antibiotic inhibition diameters and the MICs varied depending on the antibiotics, bacterial species and type of aquatic environment hosting the microorganism. Relatively lower MICs were recorded with Cefotaxim against different bacteria in slaughterhouse wastewater, in river water and in well water. Antibiotic resistance was noted with all strains from hospital wastewater. Significant differences (P˂0.05) amongst antibiotic inhibition diameter was noted for K. pneumoniae and S. typhi in most cases. The relative variations in the action mechanisms amongst antibiotics and the intrinsic defense potential of each bacterial strain, as well as the potential influence of the physicochemical properties of each water medium, could partly be at the origin of the relative differences observed at the phenotypic level. It seems necessary to explore the diversity, similarities and differences amongst antibiotic resistance genes in these different types of aquatic biotopes.

Groundwater is utilized as a clean water source including in Pelauw and Kariu Villages. Drilling and excavating are frequent techniques utilized in the construction of wells that serve as sources of groundwater. As a result of the ocean encircling the majority of this area, salinity may infiltrate wells. Consequently, the purpose of this study was to ascertain whether seawater intrusion had occurred in 12 nearby wells. Major ion tests were carried out in the lab, while surveys and measurement fields were carried out for the sampling procedure. Ion Cl, EC, TDS, Simpson ratio, and BEX data are used in the analysis to determine whether seawater intrusion is present. Additionally, the Piper diagram is used to categorize different types of water based on the outcomes of the main ion test. The findings indicated that Cl-, EC, and TDS levels have increased at a number of the sampling sites. At point A09, there is an indication of seawater intrusion based on the BEX values, which shows a negative number. The majority of the well water, as determined by a water classification analysis using the Piper diagram, is of the calcium carbonate type. Meanwhile, the remaining portion is separated into the calcium sulfate and sodium bicarbonate types.
