Surface water analysis

This article presents a mini-control analysis of surface waters at the wastewater discharge site after treatment. The cleanliness of natural water bodies in populated areas is always a problem of concern to people. This is all the more important if there is a water intake from this natural reservoir for food supply to the population. The problem is also aggravated by a large population, many enterprises with various wastes and many other reasons. In our mini-study, an attempt is presented to independently "check" how much official information about the cleanliness of reservoirs in places where wastewater is discharged corresponds to the reality. Compare the results of the analysis in a large settlement with the analysis of a regular settlement.
