Those numbers collected in Padua in the third stage of the event raise some alarm bells Operation Riversthe campaign of citizen science and scientific environmentalism of Legambiente Veneto.
For the Padua stage, the waterways put under the magnifying glass were: the Padua section of the Bacchiglionemonitored in 3 points, and the Piovego channel, with a single point.
The parameters observed in this fourth edition, in addition toEscherichia colithe fecal bacteria that allow us to verify the state of water purification, are the glyphosate and, new for 2024, i PFASchemical compounds used since the 1950s that are increasingly present in water and harmful to the environment.
And it is precisely with respect to these evaluation criteria that the data collected on the Padua section are not encouragingIndeed, they highlight a situation of growing difficulty.
«This year too, the results of our monitoring along the Bacchiglione highlight a situation that presents some critical issues for its stretch in the province of Padua» he declares Francesco Tosato, Spokesperson for Operation Rivers and President of Legambiente Padua.
«The extent of fecal bacteria values in the locality Roncajette» he explains «despite being below the recommended discharge limit, for the fourth consecutive year it was above 1,000 MPN/100ml (method used for the analysis of microorganisms in water). There was also a significant breach in the canal It’s rainingeven higher 6,867 MPN/100ml”.
At the basis of this condition there are several possible variables «Bad or insufficient purificationpresence of illegal discharges or spills or the lack of connection to the sewerage system of some buildings, are some of the possible causes” explains Tosato “The situation from a chemical point of view also deserves attention, while awaiting the results of our analyzes also for the Vicenza stretch, the monitoring carried out constantly by Arpav since the substances herbicides found in the river basin Bacchiglioneremind us of how urgent a national law on multi-residues is, which prohibits the co-presence of active ingredients in agriculture”.
