GeoGold Kárpátia Ltd.'s latest water research projects in Transylvania

Abstract

The extreme weather conditions of recent years have affected Transylvania as severely as the rest of Europe. 2022 was the third hottest year on record, and the spring and summer drought severely limited agricultural activities and negatively affected large-scale livestock production as well. Surface water extraction points have been drastically reduced, and low-flowing streams, shallow groundwater wells and springs have dried up. River flows have fallen to one third, and the Mureș, Someș and Criș rivers have set century-long negative water level records. A particular problem is that the municipal public water supply in Romania is 74% built, according to the National Institute of Statistics. In practice, the water supply of many municipalities is based on water resources from which continuous service cannot be guaranteed. In July 2022, more than 200 municipalities had water restrictions.

The local governments of Dealu, Lupeni, Sovata, Corund, Atid, Dărjiu, Ulieși, Reci, Joseni decided to explore the underground water resources and to provide the financial capacities for drilling wells and building pipelines in order to ensure a long-term and safe drinking water supply.  As an example, we describe our water exploration in Atid. We will also discuss the geophysical survey for the ceramics and building materials factory in Săndulești, near Turda. The geophysical investigations were carried out using the electrical resistivity tomography (ERT) method with the SYSCAL PRO SWITCH 96 -384 instrument from IRIS Instruments, France.
