“…The maximum mean TDS (1532 mgL -1 ) of water was observed at downstream. The highest TDS and EC due to runoff inflow from both uraban and rural regions as well as leachate from a nearby landfill site (Kasa et al, 2022). The highest mean concentration of fluoride (0.12 mgL -1 ) was recorded at downstream.…”

The present investigations were focused on the systematic analysis of surface water quality of the Thamirabarani River from upstream (Pechiparai dam to Gnaramvilai) to downstream (Vettuvenni to Thengaipattinam estuary) during the period from September 2020 to January 2021. The different hydrochemical parameters such as temperature, pH, EC, TDS, fluoride, turbidity, nitrate, phosphate, sulphate, chloride, calcium, magnesium, total hardness, DO, BOD, bicarbonate, carbonate, sodium and potassium were determined upstream (S1-S5) and downstream (S6-S10) of the river water samples. The results showed that the weighted Arithmetic Water Quality Index (WAWQI) values designated two sampling stations out of ten sampling stations 'Good' category and another eight sampling stations 'poorunsuitable' category. The results obtained were subjected to multivariate statistical analysis using Correlation matrix the significant relationship among the parameters (significance level with 0.01 and 0.05) PCA and Cluster was also calculated to determine the high pollution loads in the water sample. The mean values of the respective major ions determined are represented in the Schoeller-Berkaloff diagram. From this study the water quality was severely polluted both upstream and downstream region the water quality index and multivariate techniques can be employed for monitoring river resources which can help inadequate planning and management of the Thamirabarani river system.

“…When LSI equals zero, no calcite can dissolve nor precipitate, whereas when it is positive (respectively negative), calcite can form (dissolve). LSI can give indications on the usability of water for agriculture [26,36] or its drinkability [37], and it is part of a set of indicators designed to characterise the aggressiveness of water in water supply networks.…”

The common phenomenon observed for concrete in aggressive water is leaching, which involves the dissolution of cement hydration products. Many studies have focused on leaching in demineralised water or acid attacks, but mineral water still deserves further investigation. In most standards, the aggressiveness of a given water body is determined by its pH and not its composition. The effect of the calcium content of the water on degradation is yet to be determined. In this paper, the leaching of Portland cement-based mortar was induced by two types of drinking water with different calcium contents and buffer capacity in controlled conditions. The Langelier saturation index (LSI) was used to describe water aggressiveness based on the calco-carbonic equilibrium. The studied waters had the same pH but LSIs of +0.5 and −1.0 corresponding to scaling with respect to aggressive water; demineralised water was used as a reference. Microstructural damage was checked by TGA and X-ray microtomography. Macroscopic measurements were used to monitor global degradation. The soft water caused a 53% deeper deterioration of the mortar sample than the hard water. Soft water-induced leaching was found to be similar yet slower to leaching via demineralised water (with a mass loss of −2.01% and −2.16% after 200 days, respectively). In contrast, hard water induced strongly time-dependent leaching, and the damage was located close to the surface. The roughness of leached specimens was 18% higher in hard water than in soft water. The formation of calcite on the sample surface not only affects the leaching rate by creating a protective surface layer, but it could also act as a calcium ion pump.

Water bodies are containers that receive a large load of pollutants through the release of domestic, industrial, and agricultural e uents. With this focus, this work aimed to conduct a temporal-spatial variability study in the Rio de Ondas Hydrographic Basin through multivariate statistical analysis. For this, seventeen collection sites were established in four stations along the Rio de Ondas and its tributaries between 2017 and 2018. Ionic chromatography with suppressed conductivity was used for ions determination, while ICP-OES determined metals' total concentrations. The land use and occupation assessment between 1985 and 2015 was conducted using images from Landsat 5 and 8 satellites and the descriptive and multivariate analysis of the data using version 10 of the Statistica software. The results showed that, in thirty years, there was a growth of 569% of agricultural activities in the watershed area, with signi cant suppression of native vegetation, favoring the transport of pollutants to rivers. Ca 2+ , PO 4 2− , Al, Cu, and Zn concentrations showed a statistically signi cant difference between the seasons, with higher medians in the rainy season. Rainy season in uenced the formation of three groups in the PCA, consisting of electrical conductivity, salinity, TDS, and PO 4 2− (group 1); temperature, Fe, SO 4 2− and Cl − (group 2); and Ca 2+ , Mg 2+ , Na + , and HCO 3 − (group 3). The strong correlation between parameters of each group indicates anthropic in uence on the watershed's water quality. However, levels are within the potability standard.
