We did a physico-chemical analysis of bottled water (in plastic bottles) by GLOBE protocol, after storage under different conditions. In cooperation with the Institute for Quality Assurance (ZIK) we conducted the control of metals in water. We also conducted a survey, since we wanted to investigate the habits of our students and school staff regarding the use of plastic packaging, as well as awaken the issue of waste because of plastic packaging. We have asked questions souch as: Does water quality influence on how we store bottles within the shelf life? How many percent of our school students are using water bottles onlz once? How much is the share of our school students who properly dispose of used packaging in general? Based on the physico-chemical and organoleptic analyzes and spectrophotometric measurements, we have not found any significant differences in the quality of drinking water depending on the storage conditions, so our hypothesis that the storage mode will cause poorer quality within the deadline has not been confirmed. Our assertion that a large proportion of students using daily bottled single-pass bottles is confirmed (84.5%), while teachers and other school staff are more oriented to alternative packaging. The claim that our school students have a habit of recycling waste is partially confirmed because about 50% of respondents confirmed this. We also affirmed the claim that most students did not check the date of production, and generally declare on plastic bottles when purchasing as a guideline for further education. We think that they could be more responsible for the recycling of waste packaging and that one-time plastic bottles should be replaced with bottles that are a viable alternative.
