In this work, a physical-chemical, elemental and microbiological groundwater monitoring was performed on wells of the Serra Geral aquifer, located in the western region of the Brazilian state of Paraná, along with an evaluation of the elemental composition of soil sediments in the region of groundwater monitoring. The monitoring was carried out in 10 wells distributed throughout the rural area of the municipality of Toledo-PR. Elemental analyses were performed using the analytical technique of total reflection X-ray fluorescence spectrometry. From the results obtained, it was observed that in some wells, iron and lead concentrations were above the maximum limits allowed by the Brazilian legislation in some months, demonstrating that the evaluated groundwater is susceptible to contamination. By the analysis of the soil sediments, the presence of iron and lead in the region soil/rock was verified, which may be associated to rainwater percolation making it necessary to periodically monitor the groundwater consumed by the population of the municipality of Toledo-PR.
在这项工作中，对位于巴西巴拉那州西部地区的塞拉热拉含水层的水井进行了物理化学、元素和微生物地下水监测，并对地下水监测区域的土壤沉积物的元素组成进行了评估。监测在托莱多-巴拉那州农村地区分布的10口水井中进行。使用全反射X射线荧光光谱分析技术进行元素分析。从获得的结果可以看出，在某些月份，一些水井中的铁和铅浓度高于巴西立法允许的最大限值，这表明评估的地下水容易受到污染。通过对土壤沉积物的分析，证实了该地区土壤/岩石中存在铁和铅，这可能与雨水渗透有关，因此有必要定期监测托莱多-巴拉那州居民使用的地下水。
