Regional Network for Environmental Quality: groundwater. Data for 2016

_Chemical, chemical-physical and quantitative data year 2016_ Data are presented on the monitoring carried out in 2016 in the stations of groundwater bodies belonging to the regional environmental quality network, pursuant to DIR 2000/60/EC. The monitoring of groundwater bodies belonging to the regional network established pursuant to Directive 2000/60/EC continued in 2016, concluding the first three years of the 2015-2021 planning cycle, as requested by the Hydrographic District Authority. Between 2014 and 2015, a review of the water bodies and the network was carried out, in order to better describe the environmental status of the underground water bodies in the region; the results of the 2014-2016 monitoring, supplemented subsequently by the monitoring already underway for the three-year period 2017-2019, will help to obtain an overview of the environmental status of groundwater and, once the six-year cycle included in the 2015-2021 district planning cycle has been completed, will provide guidance for the revision of the PdG itself, identifying the necessary measures to maintain or improve the quality of water bodies.
