本研究共使用了25份饮用水样本。调查的环境参数包括pH、电导率、总溶解固体(TDS)、总悬浮固体(TSS)、溶解氧(DO₁)、/ DO₅、盐度、电阻率、总大肠菌群(作为在分配系统中可能存在生物膜的指标)和生物膜。在加沸水中观察到总大肠菌群的总患病率为1。和负沸水饮用水样本，除了女性宿舍显示中度染色生物膜定性测试。对于负沸水样品，pH值在5.04±, 0.47 - 6.82±, 0.48;总悬浮物之间范围0.09 ± 0.05 - -0.17 ± 0.02,总溶解固体介于4.07 ±之间;0.73 - 5.58 ± 0.70,电导率值介于8.02 ±之间0.90到11.54 ± 1.67,溶解氧之间的远程1.97 ± 0.26 - 3.12 ± 0.13,DO₅，范围为1.91±电阻率为7.79±0.13 ~ 10.88±0.18。值 为+煮沸和过滤样品显示pH范围 6.02±0.26至6.95±0.26; conductivity 7.21±0.10 to 9.88±0.67; DO ranged between 1.01±0.14 to 2.08±0.35, DO 5 was 1.02±0.02 to 2.01±0.38, TSS and TDS ranged between 0.02±0.001, 3.74±0.62 to 0.03±0.002 and 4.95±0.42 respectively while resistivity ranged between 1.02±0.11 to 1.98±0.16. For all parameters analyzed, values obtained falls within the WHO limit for potable water except for the qualitative biofilm test on FSH minus-boiling water sample which gave moderate stain with 0.1% crystal violet stain and the pH values which fall below WHO acceptable limits. Boiling and filtration of potable water irrespective of the source is campaigned from this study in order to enhance the prevention and management of water borne diseases within the institute community.
