Regional Network for Environmental Quality: groundwater. Data for 2015

_Chemical, chemical-physical and quantitative data year 2015_ Data on the monitoring carried out in 2015 at stations of underground water bodies belonging to the regional network for environmental quality, in accordance with DIR 2000/60/EC, are presented. Monitoring of regional underground networks for which an optimisation functional review had already been carried out in accordance with regulatory updates took place in 2015. The 2015 monitoring in fact represents both the second year of the 2015-2021 planning cycle as required by the Hydrographic District Authority for the purpose of the correct review of the third cycle of PdG, but it also represents the last year of monitoring of the first six-year start of Directive 2000/60/EC, an important year for the verification of the required objectives; indeed, the Directive called for the achievement of a good status in 2015 and risk analyses were carried out on the basis of that request. The classification, which will reasonably be completed by the end of the year, will therefore allow a first verification of the correctness of what was assessed.
