“…The availability of electrolytes in the groundwater system is the consequence of the dissolution of minerals by water. Water from precipitation infiltrates the soil, dissolves minerals, and carries suspended particles along its path (Prakash and Somashekar 2006;Chegbeleh et al 2020).…”

The municipality of Santa Ignacia in the Province of Tarlac is highly dependent on groundwater as its major water supply for various purposes, but there is inconsistency in monitoring groundwater quality in the area which may impact the health of consumers. This study presented the preliminary assessment of groundwater quality through the application of spatial mapping. Out of 6,815 wells in the municipality, groundwater samples were collected from 274 hand pump wells. The measurements of selected groundwater quality parameters such as pH, conductivity, nitrate, nitrite, and iron of groundwater samples were determined on-site. The geographical coordinates of sampled wells and measurements of groundwater quality parameters were used in Geographic Information System software, QGIS, to construct the spatial distribution and spatial variation maps. The values of measured parameters were interpolated using the inverse distance weighted technique to predict the parameters at other sites in Santa Ignacia. Spatial variation maps revealed that the groundwater quality parameters varied in the municipality. All measured parameters, except the nitrite content, were within the acceptable limits set by the World Health Organization for drinking water. The high level of nitrite content in groundwater may be attributed to the application of fertilizers during agricultural activities. The nitrite content of groundwater, which exceeded the permissible limit, may cause long-term public health problems. Hence, an upscale evaluation and monitoring of groundwater quality and existing anthropological activities in the municipality are highly recommended. The identification of other possible source(s) of nitrite is necessary to lessen possible contamination risk and to protect the groundwater sources in the municipality. The results of this preliminary study would be useful in prospect studies of groundwater quality in the study area and in other provinces in the Philippines.

“…The Q-and R-mode HCAs of the groundwater samples were further introduced to outline groups of samples with the content of alike hydrochemical parameters and to provide helpful statistics to the results gotten from PCA. The HCAs were computed by Ward's agglomeration method and squared Euclidean distance was measured to nd the distance between clusters of analogous parameter contents (Bhuiyan et al 2016;Chegbeleh et al 2020). Furthermore, including Gibb's diagram, various bivariant plots are constructed to evaluate the hydro-geochemical processes in the study area.…”

Groundwater is a vital source of irrigation water, and it provides over 80% of the irrigated water supply in Bangladesh. The study aimed to assess the status of irrigation water of the Ganges river basin areas in the middle-west part of Bangladesh through the hydrogeochemical characterization and classification of groundwater. The study parameters were pH, EC, TDS, Ca2+, Mg2+, total hardness, Na+, K+, B, Cl−, HCO3 −, SO 42−, NO3 −, and PO43− along with irrigation water quality index (IWQindex), Na%, soluble sodium percentage, sodium adsorption ratio, residual sodium bicarbonate, magnesium adsorption ratio, permeability index, and Kelley’s ratio. The results showed that most of the water samples were acidic in the pre-monsoon and alkaline in the post-monsoon seasons, and the water type was Ca-HCO3. The significant geochemical process in the area determined was calcite and dolomite mineral dissolution, and there was no active cation exchange, and silicate weathering occurred. The statistical analyses showed that both the geogenic and anthropogenic sources were controlling the chemistry of the groundwater aquifers. Concerning irrigation water quality, the results revealed that all the quality parameters and IWQindex (32.04 to 45.39) were within the safety ranges, except for the EC and total hardness. The study results would be useful for future groundwater monitoring and management of the Ganges basin areas of Bangladesh part.

This paper presents the results of the assessment of interactions in the water-rock system using an integrated approach including the balance method and the method of geochemical (thermodynamic) modelling. Assessment is carried out for conditions of Cenomanian-Callovian and Bajocian aquifers within the Obolon groundwater intake structure in Kyiv. The results obtained demonstrate that groundwater of the Cenomanian-Callovian and Bajocian aquifers within the Obolon groundwater intake structure differ in chemical composition, physicochemical conditions, and especially in the formation of water composition due to the interactions in the water-rock system. This paper proposes division of water into groups, taking into account both the features of chemical composition and its formation process. The water group characterized by anomalous ratio of chlorine and sodium is distinguished, as well as the possible formation mechanism of this water composition is proposed. The chemical composition of the waters of both aquifers meets the requirements of Ukrainian legislation for drinking water quality (GSanPiN 2.2.4-171-10). Groundwater quality of the Cenomanian-Callovian complex is shown to be higher than that of the Bajocian aquifer. For both aquifers, the water of higher quality is the one with cationic composition determined largely by ion exchange. The ion exchange processes can be controlled to a certain extent by regulating the water withdrawal from the wells, and hence the water quality can be regulated in this way as well. Another way to regulate water quality could be the mixing of water from two aquifers during water treatment, which would, on the one hand, compensate the insufficient water quality of individual aquifers and, on the other hand, provide for continuous well operation contributing to the maintenance of more or less stable physicochemical processes. However, these hypotheses require further detailed consideration and, if confirmed, a detailed justification of their feasibility.
