Drinking water in Frattamaggiore
One supply zone, published by Ottogas Srl. 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).

Ottogas SrlNo date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.

| Nitrite | <0,05 mg/l NO2 below limit of quantification | 0.5 mg/l | < 10 % * | Mean · Frattamaggiore, Marzo-Aprile 2020 |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.

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.
Legal basis: Art. 18 D.Lgs. 18/2023 as amended by D.Lgs. 102/2025 (transposition of EU Directive 2020/2184). The values are not official — the publication of the Gestore, to which every row links, remains authoritative.
