1. Group 2 Tap water analysis

2. In Campania there are two big areas: the “coastal” area, supplied by the Campania aqueduct and by the aqueduct of western Campania; the “inland” area supplied by more aqueducts, set up in a cooperate management scheme

3. Our area is situated inland and is supplied by this system.

4. There might be cuts and falls of water supply due to the impoverishment of the water table and to a higher demand of water in summer periods. For this reason there are tanks of water supply (storage) in almost all public buildings

5. There is a water tank in our school too

6. it has been interesting to analyse both the water from the tank (the data we got are the first two in the table) and the water coming directly from the aqueduct
