Principal Component Analysis in Long Term Assessment of Total Viable Plate Count of Municipal Water Distribution Network System in Healthcare Facility

The microbial quality of water is a critical safety aspect that should not be overlooked, especially when considering human consumption in the facilities for healthcare and treatment health compromised populations. present work aimed to study municipal network city within facility microbiologically. implementation multivariate analysis was conducted over collected data decipher trends microbiological count samples from different points-of-use. statistical involved an Eigenvalue determination, score graph, loading plot outlier diagram. Data showed clustering tendency with aberrant values could observed. first component appeared associated bioburden density water. While other link relative locations distribution points length lines source feeding great extent. two components explained more than 55% variations data. A property highlighted strong agreement between order points-of-use ratio factor which obtained Total Viable Count hypothetical distance sampling port reference entrance. Thus, there evidence variation affected by biological stability system needed attention improvement plan better control content prevent possible excursions future. valuable perspective approach quantitative examination system.
