“…They are characterised by very stable parameters, such as temperature and physicochemical composition. In most cases, well water can be used for drinking purposes, provided that the chemical composition meets the sanitary requirements (Cierniak et al, 2020;Hermanowicz et al, 1999;Rodrigues-Narvaez et al, 2017;Romero et al, 2014;Jha et al, 2020;El Baba et al, 2020;Mohamed et al, 2019;Kapembo et al, 2022;Abbasnia et al, 2019).…”

The aim of this study was to analyse the quality and compare the functional value of water from traditionally dug and drill wells located in west Poland. Basic physicochemical and microbiological (Escherichia coli in 100 ml, coliform bacteria in 100 ml, enterococci in 100 ml, total number of bacteria in 1 ml grown at 22 °C, total number of bacteria in 1 ml grown at 36 °C) were determination for the water samples. Additionally, some waters samples were analysed of the presence of heavy metals , TN (total nitrogen), TOC (total organic carbon) and NPOC (dissolved organic carbon). The conducted research has indicated that mineral and microbiological contamination occurs in the waters collected from the wells. This confirms that the wells were not sufficiently protected and that penetration of pollutants into the water occurs from their immediate surroundings, geological layers with which underground water resources come into contact.

Impact of Artificial Infiltration on the Removal of Nonsteroidal Anti-Inflammatory Drugs during Treatment of Surface Water

et al. 2021

View full text Add to dashboard Cite

The content of pharmaceuticals in natural waters is steadily increasing. Especially nonsteroidal anti-inflammatory drugs (NSAIDs) are often detected in natural waters due to their widespread use. This group of compounds includes commonly used representatives, such as paracetamol and ketoprofen. The quality of natural waters determines the processes applied for the treatment of drinking water. The methods used in order to remove pharmaceuticals from treated water include adsorption and biologically active filtration. Both processes also occur during artificial infiltration (forced flow of intake surface water through the ground to the collecting wells) at surface water intakes. The processes, which occur in the soil, change the water quality characteristics to a great extent. The goal of the study was to evaluate the removal efficiency of paracetamol and ketoprofen in the process of artificial infiltration used as a pre-treatment of surface water. The studies were conducted at a field experimental installation located at the technical artificial infiltration intake. The experimental installation consisted of three metering wells (piezometers) which were located on the way between the bank of the infiltration pond and the collecting well. The collected water samples allowed to evaluate the change of selected NSAIDs concentrations during the passage of water through the ground. The analysis procedure included solid phase extraction (SPE) and high-performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Removal of the studied NSAIDs in the infiltration process occurred with variable effectiveness throughout the year. Paracetamol was removed with annual efficiency equal to 42%, although no significant removal of ketoprofen was observed.
