The localization and characterization of hydraulically active zones in a\u0000geothermal well is a major task in understanding the hydro geothermal\u0000reservoir. This is often done based on interpretations of spinner flow meter\u0000measurements that are performed at the end of the well test while injecting\u0000cold water. Once a production well is equipped with an electric submersible\u0000pump, data collection inside the reservoir and monitoring of the flow zones\u0000is usually barely possible. In a 3.7 km (MD) deep geothermal production well\u0000in Munich, Germany, it was successfully demonstrated in 2019 that a\u0000permanently installed optical fiber cable could close this measurement gap.\u0000We used this fiber-optic monitoring system to collect distributed\u0000temperature data once the well was set into production. We inversely modeled\u0000the inflow from the formation into the borehole from the production\u0000temperature data with an energy and mass balance model. The derived flow\u0000profile correlates with previous flow meter analysis and indicates that a\u0000karstified region at the very top of the reservoir is the driving factor for\u0000hydraulics and obtained production temperature. Qualitatively, the two\u0000profiles acquired by distributed temperature sensing (DTS) and flow meter\u0000are matchable, yet the production inflow profile by DTS logging is more\u0000differentiated compared to spinner flow meter logs interpretation during\u0000injection.\u0000","PeriodicalId":7329,"journal":{"name":"Advances in Geosciences","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83289995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Puigserver, Silvia Burdons, M. Enrich","doi":"10.5194/adgeo-59-59-2023","DOIUrl":"https://doi.org/10.5194/adgeo-59-59-2023","url":null,"abstract":"Abstract. Groundwater is a vital resource for the development of\u0000urban areas, where the problem focuses on the quantity and on the quality of\u0000this freshwater resource. Barcelona is a good example as because currently\u0000groundwater is used for irrigation of parks and gardens and street cleaning\u0000due to its poor quality as drinking water source. Among the pollutants found\u0000in groundwater, of special interest are contaminants of emerging concern\u0000(CEC), as they pose a high risk to the aquatic environment and human health.\u0000The behaviour, spatial distribution and processes that control them in the\u0000aquatic environment are still uncertain and most of them are unregulated. In\u0000this paper we study the inputs and processes controlling the hydrochemistry\u0000of Barcelona urban groundwater with special emphasis on the CEC. We selected\u000029 CEC that were detected at high concentrations of up to 1 µg L−1 (e.g.\u0000gemfibrozil, benzotriazole, among others). Towards the higher zones we\u0000identify groundwater with relative low mineralization more proximate to the\u0000natural recharge composition, while towards the urban area the anthropic\u0000inputs are evident (e.g. nitrate concentrations range from 50 to 200 mg L−1).\u0000Near the Besòs river there is a clear contribution from this superficial\u0000water highly polluted, mostly from wastewater treatment plant (WWTP)\u0000discharges, and reducing conditions. The main contributor of CEC pollution\u0000in groundwater was the river-aquifer interaction (Besòs river), while\u0000towards the urban area it might come from sewage seepage and probably a\u0000minor input from urban runoff. The redox state of these waters seems to\u0000control the fate and occurrence of several of these CEC. The limitations of\u0000this study are restricted to a single sampling campaign, therefore these\u0000results should be corroborated with other sampling campaigns, including the\u0000seasonal variations, which would allow establishing more robust conclusions.\u0000","PeriodicalId":7329,"journal":{"name":"Advances in Geosciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90189763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
