摘要

背景和目标:保护水资源成为世界许多地区关注的一个主要问题,因为它旨在为人类提供安全和健康的水。水质监测是一种流行的工具,可以确保水质安全,并在社区健康的允许范围和标准内。为了提供修复干预措施和战略,制定了水质监测计划,以描述河流的水质和分类。方法:本研究进行了环境分析,以确定周围环境的现有条件和过程,如土地利用、排水模式、河流勘测,并进行了关键访谈,以描述巴郎盖剖面以及社区的用水和实践。水质监测包括对十个水质参数的评估:温度、pH、溶解氧、总溶解固体、总悬浮固体、磷酸盐、硝酸盐、油脂、氯化物和大肠杆菌。结果:研究结果表明,水质符合十项水质标准。四个站测得的磷酸盐含量在2.40-4.50 mg/L之间,超过了允许的0.50mg/L;油和油脂超过标准2 mg/L,在2号、3号和4号站的测量值为2.40-4.60 mg/L;而所有站点的氯化物测量结果都证明该水是含盐的,其值超过了250mg/L的淡水需求;监测站2、3和4的TSS在32.30至49.3mg/L范围内超过30mg/L的标准。在所有采样站采集的水样中也检测到大肠杆菌。计算出的水质指数为39.02,说明水很差,总是受到损害,并受到周围环境的威胁。结论:磷酸盐、油脂、氯化物和TSS的测量浓度超过了水质要求,表明水受到了污染。在所有水样中检测到大肠杆菌,进一步建议禁止娱乐活动,以避免意外摄入和皮肤接触受污染的水。由于排水系统不可靠、缺乏适当的卫生设施以及社区的收集和处理行为,周边居民区、商业区和农业区的现有活动加剧了水污染。由此,可以为如何修复和保护河流提供科学依据,并为决策者和水资源管理者实施实现可持续水资源的战略提供指导。

Laboratory analysis to determine the accurate characteristics of urban food waste
BACKGROUND AND OBJECTIVES: Safeguarding water resources became a major concern in many parts of the world as it aims to provide safe and healthy water for humans. Water quality monitoring is a popular tool in ensuring water quality is safe and within the allowable limits and standards for the health of the community. To provide interventions and strategies for the rehabilitation, a water quality monitoring plan was conducted to describe the water quality and the classification of the river.METHODS: This study conducted an environmental analysis to determine existing conditions and processes in the surrounding environment such as the land use, drainage pattern, reconnaissance survey of the river, and a key interview to describe the barangay profile and the community's water use and practices. The water quality monitoring covers the evaluation of ten water quality parameters: temperature, pH, dissolved oxygen, total dissolved solids, total suspended solids, phosphate, nitrate, oil and grease, chloride, and E. coli.FINDINGS: Results of the study presents the water quality against the ten water quality criteria. Phosphate measured on four stations ranges between 2.40-4.50 mg/L exceeding the allowable 0.50mg/L; the oil and grease exceeds the standards 2 mg/L with measured values of 2.40-4.60 mg/L in stations 2, 3, and 4; while measured chloride in all stations prove that the water is salty with values exceeding the freshwater requirement of 250mg/L; and the measured TSS in stations 2, 3 and 4 ranges from 32.30 to 49.3 mg/L exceeds the standards of 30mg/L.  E. coli was also detected in water samples collected in all sampling stations. The computed water quality index of 39.02 described water as poor, always impaired, and threatened by the surrounding environment.  CONCLUSION: The measured concentrations for phosphate, oil/ grease, chloride, and TSS exceeds the water quality requirement suggesting that the water is contaminated. The E. coli detected in all water samples, further recommends prohibition of recreational activities to avoid accidental intakes and skin contact on the polluted water.  The existing activities in the surrounding residential, commercial and agricultural areas contributed to water contamination as aggravated by the unreliable drainage system, absence of proper sanitation facilities, and collection and disposal behavior of the community. From this, a scientific basis can be drawn on how the river can be rehabilitated and protected and serve as guide for policymakers and water managers on implementing strategies to achieve sustainable water resources.
