Abstract

This study investigates the impact of pipeline corrosion on drinking water quality, with a focus on secondary contamination caused by metal ion release and biofilm formation. The technical condition of water supply systems was assessed using metallographic and elemental analyses, while the presence of corrosion products was examined through spectroscopic. The results confirm that corrosion of pipelines contributes to the accumulation of iron oxides and the formation of microbial biofilms, leading to deterioration in water quality. It has been established that damage to protective coatings on steel pipes accelerates oxidation, increasing the risk of microbiological contamination. Additionally, disruptions in water supply schedules contribute to water stagnation, further intensifying contamination risks. Furthermore, the release of heavy metal ions from corroded pipelines poses potential long-term health risks for consumers. To mitigate these issues, a water purification system is proposed at the consumer supply stage, integrating multi-stage filtration, sorption technologies, and disinfection methods. This approach enhances the removal of corrosion byproducts and microbiological contaminants, ensuring safer drinking water. The study highlights the necessity of corrosion control strategies, regular pipeline maintenance, and systematic monitoring to reduce contamination risks and improve water supply quality and public health safety.
