The Veneto Region has identified a series of initiatives to bring down and control PFAS concentrations in water intended for human consumption. Recently the DGR 691/2018 was issued which, by modifying the "Surveillance Plan on the population exposed to perfluoroalkyl substances", has redefined the areas of interest.
This site presents the results of the analyzes carried out by ARPAV on water intended for human consumption at the exit of the drinking water treatment plants, located in Brendola, Lonigo and Sarego, which serve, in whole or in part, the 30 municipalities falling within the area of Maximum Health Exposure (Red Zone).
For 21 of these municipalities, identified by the DGR 2133/2016, the previus DGR 1591/2017 has established that, over a period of six months, the values, of PFOA + PFOS must be less than or equal to 40 ng / L, thanks to the adoption of a series of interventions aimed at experimenting treatment technologies for the reduction of pollutant loads in water intended for human consumption.

(5) From 16/07/2018 Lonigo is no longer served by Acque del Chiampo. The monitoring of the water quality served to the municipality of Lonigo is guaranteed by Acque Veronesi. The withdrawal point of Acque del Chiampo can be reactivated when necessary.
( NQ ) NQ: Not quantifiable. The substance or group of substances are below the quantification limit.
The limit is 5 ng / L corresponding to 0.000000005 g / L.
