PUG - Constraints form - Infrastructure, soil, servitude ‘Sites subject to remediation procedure’

the dataset is derived from the cartographic layer used to draw up the Table of Constraints on Infrastructure, soil and servitude, but only shows the centroids of the polygons of the ‘sites subject to the remediation procedure’ – updated in December 2019.Contaminated sites are areas affected by anthropogenic phenomena (activities in course/concluded) which have caused the introduction of one or more pollutants into at least one of the environmental matrices (soil, subsoil, groundwater), altering the natural content of some elements and determining the overcoming of Eligible concentrations for use (CSR - risk threshold concentrations). CSR identify in fact the levels of contamination related to the reality of the site (site - specific), which meet the risk acceptability criteria under the legislation in force. The identification of sites where an alteration of environmental matrices has been detected is aimed at highlighting those areas in which, as a result of specific interventions, it is it has been verified that the quality of the matrices themselves and the exposure levels of the targets human beings are acceptable for the use for which such sites are or will be intended.本数据集源自用于编制《基础设施、土壤与地役权限制表》的制图图层，仅展示了“需实施修复程序的场地”多边形的质心，相关数据于2019年12月完成更新。 污染场地指受人为活动（正在进行或已完成的活动）影响的区域，此类活动已向至少一种环境介质（土壤、下层土、地下水）中带入一种或多种污染物，改变了部分元素的自然含量，并导致超过了场地适用合规浓度（Eligible concentrations for use，缩写为CSR，即风险阈值浓度）。CSR实际上是与场地实际情况（场地专属）相关的污染水平，符合现行立法规定的风险可接受标准。 对已检测到环境介质发生改变的场地开展识别，旨在明确那些通过针对性干预措施后，已证实其环境介质质量与人体暴露水平符合场地当前或未来既定用途要求的区域。
