1. Evaluate the quality of artesian water proposed for hospital water supply: odor – taste – turbidity – 0.5 mg/L, iron – 0.3 mg/L, fluorides – 1.2 mg/L, microbial count – 80, Total coliform bacteria, in 100 mL – absent.
2. The tap water has an odor and a taste, turbidity 2.0 mg/L, color — 30 °, microbial count — 90, residual chlorine 0.1 mg/L, F content — 0.1 mg/L, phenol index — 0.1. Can this water be consumed? Provide an assessment of the water quality.
3. Assess the technical condition, water quality in the well, and propose measures to improve decentralized water supply for the population. In the village of X, water supply is provided from the only public well for the entire village, for which no sanitary passport has been drawn up. The well is fed by groundwater, with a depth of 12 meters, an old wooden structure, and flagstones around the well, with water pooling in some depressions. The well is public. A gate is installed for water collection. Next to the well, there is a trough for livestock watering, and the area around is marshy and contaminated with manure, and the water is not chlorinated. The population complains of high water hardness. Analysis results: Turbidity, mg/L — 2.5 Color, ° — 30 Taste — 3 Odor — 3 Nitrates, mg/L — 55 Chlorides, mg/L — 480 Sulfates, mg/L — 300 Total coliform bacteria, in 100 mL — 9 Total microbial count, in 1 mL — 250 Total hardness, mg-eq/L — 8 Dry residue, mg/L — 1450
