Background: Access to safe drinking water remains a global challenge, particularly in arid regions such as Libya, where groundwater is the primary source of domestic water supply. This study assessed the chemical and microbiological quality of groundwater from selected domestic wells in western Tripoli and compared results with Libyan drinking water standards. Material and Methods: A total of 20 groundwater samples were collected from domestic wells (35–100 m depth) in Al-Sarraj, Janzour, Al-Swani, and Bu Ghubba. Physicochemical parameters, including pH, electrical conductivity (EC), total dissolved solids (TDS), major ions, and hardness, were analyzed. Microbiological analyses targeted total coliforms, Escherichia coli, and total bacterial counts. Statistical analysis was performed using ANOVA. Results: Most samples exceeded Libyan standards for TDS (>3000 mg/L) and total hardness (>1400 mg/L). Approximately 60% of shallow wells (35–60 m) exhibited the highest contamination rates. E. coli concentrations reached up to 129 CFU/100 mL. Overall, the majority of wells were unsuitable for human consumption. Conclusions: Domestic wells in western Tripoli exhibit significant chemical and microbial contamination, rendering them unsafe for drinking water. Urgent interventions, including regular monitoring, enforcement of drilling regulations, and public awareness campaigns, are required.

Others who have participated in certain substantive aspects of the manuscript but without intellectual input should only be recognized in the acknowledgements section of the manuscript. Also, one of the authors should be selected as the corresponding author to communicate with the journal and approve the final version of the manuscript for publication in the LJMR.
Peer-review Policy
- All the manuscripts submitted to LJMR will be subjected to the double-blinded peer-review process;
- The manuscript will be reviewed by two suitable experts in the respective subject area.
- Reports of all the reviewers will be considered while deciding on acceptance/revision or rejection of a manuscript.
- Editor-In-Chief will make the final decision, based on the reviewer’s comments.
- Editor-In-Chief can ask one or more advisory board members for their suggestions upon a manuscript, before making the final decision.
- Associate editor and review editors provide administrative support to maintain the integrity of the peer-review process.
- In case, authors challenge the editor’s negative decision with suitable arguments, the manuscript can be sent to one more reviewer and the final decision will be made based upon his recommendations.
