Evaluation of the effectiveness of filtered drinking water purification systems in Janzour Municipality in eliminating intestinal parasites

Provision safe drinking water is a fundamental public health priority. In recent years, filtered groundwater has become a widely used source of drinking water in Janzour Municipality. The present study aimed to evaluate the effectiveness of filtered drinking water purification systems in Janzour Municipality in eliminating intestinal parasites. The study's findings also serve to assure the local population about the safety and potability of the distributed water, contributing significantly to public health. To this end, 20 filtered drinking water samples were randomly collected from 20 groundwater treatment and filtration sites across the municipality. Approximately two liters of water were collected per site using clean, sterile plastic bottles. Following collection, the sample were placed in a refrigerated container and immediately transported to the laboratory at the Center for Communicable Disease Control and Prevention in Tripoli for analysis. Microscopic examination confirmed that none the samples contained intestinal parasite stages. These results demonstrate that the drinking water purification system in Janzour Municipality is highly effective in eliminating intestinal parasite contamination not only immediately after filtration but also during the storage and distribution phases. The system follows a well-designed, fully enclosed process from initial filtration through to final delivery, ensuring the continued safety and potability of the treated water.
