Assessment of typical natural processes and human activities’ impact on the quality of drinking water

Abstract

This paper provides insight into the quality of groundwater used for public water supply on the territory of Temerin municipality (Vojvodina, Serbia). The following parameters were measured: color, turbidity, pH, KMnO4 consumption, total dissolved solids (TDS), EC, NH4+, Cl-, NO2-, NO3-, Fe, Mn, As, Ca2+, Mg2+, SO4(2-), HCO3-, K+, and Na+. The correlations and ratios among parameters that define the chemical composition were determined aiming to identify main processes that control the formation of the chemical composition of the analyzed waters. Groundwater from three analyzed sources is Na-HCO3 type. Elevated organic matter content, ammonium ion content, and arsene content are characteristic for these waters. The importance of organic matter decay is assumed by positive correlation between organic matter content and TDS, and HCO3- content. There is no evidence that groundwater chemistry is determined by the depth of captured aquifer interval. The main natural processes that control the chemistry of all analyzed water are cation exchange and feldspar weathering. The dominant cause of As concentration in groundwater is the use of mineral fertilizers and of KMnO4 in urban area. The concentration of As and KMnO4 in the observed sources is inversely proportional to the distance from agricultural land and urban area. 2D model of distribution of As and KMnO4 is done, and it is applicable in detecting sources of pollution. By using this model, we can quantify the impact of certain pollutants on unfavorable content of some parameters in groundwater.

Assessing Water Quality and the Non-Carcinogenic Health Risks of Surface and Groundwater in Ibi – Taraba State

“…This implies that temperature is strongly contributing to the dissolution of variables that impact the colour and turbidity of water. Findings from other studies (Aladejana et al, 2020;Amfo-Otu et al, 2014;Khatri and Tyagi, 2015;Kurilic et al, 2015) further support this suggestion that both natural and anthropogenic factors are together playing a key role in surface and groundwater water quality. .…”

Determination of Groundwater Quality Index in Rural Area: The Case of Bartın City

“…For this reason, monitoring groundwater quality and determining the factors affecting its quality are important in terms of water quality management. Groundwater chemistry and properties are affected by many sources such as aquifer mineralogy, geochemical processes, excessive land use, source of recharge waters and anthropogenic sources [6][7][8][9]. For this reason, the sources that affect the groundwater quality can be categorized in two classes as geological and anthropogenic sources.…”

Survival of Human Norovirus Surrogates in Water upon Exposure to Thermal and Non-Thermal Antiviral Treatments

“…Several factors such as hardness, solar radiation and phosphate levels, have also been suggested to influence virus survival in the water column [22][23][24][25]. The increased use of fertilizers has also led to a rise in chemical concentrations in natural water systems [26][27][28], but the impacts of these chemicals, particularly ammonium and phosphates, on pathogen survival have not been widely studied [29][30][31][32].Due to the long-term stability of human noroviruses in the environment, an effective, economical method for eliminating the virus from surface water and produce wash water is needed. As a result, several thermal and non-thermal strategies have been investigated to inactivate human norovirus, but the results have not always been conclusive [33,34].…”
