Tap water analysis

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

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

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

There is a water tank in our school too

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

Analysis of the results• From this data we notice that there

are not remarkable variations between the two types of water

• The water coming from our taps shows that the parameters examinated do not diverge from those provvided by laws in force
