Abstract

Poor water quality is problematic for the health of public swimmers. This study focused on the water quality of three main swimming pools coded as MS, ES and HC in the city of Bujumbura, Burundi. Water samples were collected from June to the end of August 2020 and analyzed for physicochemical parameters such as pH, turbidity, conductivity, nitrates, free chlorine and microbiological parameters (total coliforms and faecal coliforms). Our results indicated that 2/3 of the sampling days showed pH >7.8 and pH<7.2 in the MS and HC pools, respectively. All these pools exhibited high turbidity whereas ES manifested very high value (6.05NTU). Free chlorine appeared very low in the MS pool with contamination by total coliforms (<1MPN 1mL-1 and 1.17x107MPN 1mL-1, <1MPN 1mL-1 and 6.32x106MPN 1mL-1, and < 1MPN 1mL-1 and 5x102 MPN 1mL-1) for MS, ES, and HC respectively. Both MS and ES pools revealed higher thermotolerant coliforms contamination of (<1MPN 1mL-1 and 2.18x104MPN 1mL-1) in MS and (<1MPN 1mL-1 and 2.32x104MPN 1mL-1) in ES, but the HC pool showed a single contamination case with values of <1UFC 1mL-1 and 5UFC1mL-1 throughout the sampling period. Additionally, extreme concentrations of nitrates (104.89 mgL-1) were observed at the ES pool. The findings showed a non-compliance with WHO standards for all three swimming pools and therefore advocates for an urgent need to monitor and treat or change the water frequently for quality assurance of swimming pools.

布隆迪布琼布拉市三个游泳池水质状况评价

水质差对公众游泳者的健康构成问题。本研究的重点是布隆迪布琼布拉市三个主要游泳池的水质，编号为MS、ES和HC。2020年6月至8月底采集水样，分析理化参数，如pH、浊度、电导率、硝酸盐、游离氯和微生物参数(总大肠菌群和粪便大肠菌群)。结果表明，MS池pH >7.8, HC池pH<7.2，占采样天数的2/3。这些池的浊度都很高，而ES值非常高(6.05NTU)。MS、ES和HC总大肠菌群污染的MS池中游离氯含量极低，分别为<1MPN 1mL-1和1.17 × 107MPN 1mL-1， <1MPN 1mL-1和6.32 × 106MPN 1mL-1， <1MPN 1mL-1和5 × 102 MPN 1mL-1。MS池和ES池均显示出较高的耐热大肠菌群污染(<1MPN 1mL-1和2.18x104MPN 1mL-1)， ES池显示出较高的(<1MPN 1mL-1和2.32x104MPN 1mL-1)，而HC池在整个采样期间均显示出<1UFC 1mL-1和5UFC1mL-1的污染病例。此外，在ES池中观察到硝酸盐的极端浓度(104.89 mg -1)。调查结果显示，所有三个游泳池都不符合世卫组织的标准，因此主张迫切需要经常监测和处理或更换水，以保证游泳池的质量。
