The most impacted waters are those forming surface and shallow reservoirs, which usually play a key role in supplying waters to civil, agricultural, and industrial activities. The terminal portion of the Metauro River plain, located in central Italy along the Adriatic Sea coastline, hosts a strategic phreatic aquifer that, along with the surface water of the Metauro River, supplies water to the local population (i.e., about 60,000 people). This shallow coastal aquifer experiences a long-lasting story of nitrate contamination since the 1970s when the increase in the use of agricultural fertilizers contributed to very high levels of pollution (NO3\u2212 &gt; 100 mg\/L). This fact prompted the local authorities to carry out remediation actions that involve a pumping system to inject the NO3\u2212-poor waters from the Metauro River course directly into the shallow aquifer. The present work was aimed at defining the contamination of nitrates in this important water resource. The main geochemical characteristics and the temporal evolution of NO3\u2212 concentrations (between 2009 and 2020), in the shallow coastal aquifer of the Metauro River plain, were analyzed by means of classical geochemical analyses and multivariate methods accounting for the compositional nature of the data, to assess the efficiency of the in-situ remediation over time.<\/jats:p>","DOI":"10.3390\/ijerph191912231","type":"journal-article","created":{"date-parts":[[2022,9,27]],"date-time":"2022-09-27T23:12:12Z","timestamp":1664320332000},"page":"12231","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Contamination Assessment and Temporal Evolution of Nitrates in the Shallow Aquifer of the Metauro River Plain (Adriatic Sea, Italy) after Remediation Actions"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0646-4562","authenticated-orcid":false,"given":"Marco","family":"Taussi","sequence":"first","affiliation":[{"name":"Dipartimento di Scienze Pure e Applicate, Universit\u00e0 degli Studi di Urbino Carlo Bo, Via Ca\u2019 Le Suore 2\/4, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8384-8696","authenticated-orcid":false,"given":"Caterina","family":"Gozzi","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze della Terra, Universit\u00e0 di Firenze, Via G.
