Drinking water in San Ferdinando di Puglia
One supply zone, published by Acquedotto Pugliese S.p.A.. The values come from the publications of the Italian water suppliers (gestori), which D.Lgs. 18/2023 requires of them from 12 January 2026. Italian parametric values apply: trihalomethanes 30 instead of 50 µg/l, chromium 25 µg/l, uranium 30 instead of 10 µg/l; for hardness there is no maximum value, it is given in French degrees (°F).

Values taken unchanged from the publications linked below — for each parameter the most recent recorded value. „—" in the parametric value column: no currently valid legal parametric value is stored in our database for this parameter; the parameter register with all parametric values is being expanded continuously.
How to read the share of the parametric value
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

The values are not official — the publication of the Gestore, to which every row links, remains authoritative.
