Abstract

This research aimed to investigate the actual water use of residents and the quality of well water used daily at the urban kampung located in Bandung, Indonesia. The status of wastewater treatment and residents' awareness of the water environment were also investigated in the target area. The methodology used included a survey of residents, water quality testing, and an assessment of wastewater practices. The results showed that approximately one-half of the respondents used water from the water utility, with the other half using well water as their main domestic water source. Identifying water sources by end-use revealed that residents mainly used bottled water for drinking and cooking. Since Escherichia coli was detected in many wells, it is not recommended that residents drink well water without disinfection. In addition, most of the wastewater in the area was discharged into a nearby river without treatment.

Abstract

This research presents a comprehensive citizen-scientific water quality assessment and evaluation, focusing on water quality at the points of water consumption in public and private high school campuses in the Province of Antique, Philippines. The water quality assessment showed that Escherichia coli was detected in several samples from tap water exclusively used for handwashing by public school students, indicating potential contamination sources such as outdated treatment facilities. To improve the WASH environment of the provincial school campuses, old facilities, such as filters and pipes, need to be checked and renovated to avoid contamination caused by penetration and leakage. School-level and individual practices, such as chlorination, covering water tanks, and encouragement of handwashing, could be the first step. The citizen scientific methodology facilitated the collection of water quality information and enhanced discussions with stakeholders, generating practical and affordable solutions based on the findings.
