Assessment of the Water Quality of Troia for the Multipurpose Usages

Abstract

The aim of this study was to determine the origin and quality of waters in Troia. For this purpose total of 25 water samples including 2 springs, 14 surfaces and 9 groundwaters, were collected at eight different times. Global positioning system (GPS) was used to determine to coordinates of sampling points. The concentration of 6 minor elements (B, Cu, F, Fe, Pb and Zn), 9 major anions and cations (Na(+), Ca(2+), K(+), Mg(2+), SO(4)(2-), PO(4)(3-), HCO(3)(-), Cl(-) and, CO(3)(2-)) were determined by spectrometric, colorimetric and volumetric methods. Water pH, EC, DO, ORP and TDS were measured in situ using probes. The data showed that the concentrations of most of minor elements were below the EPA and TSE limits except Pb which ranged between 0.001 and 4.832 mg L(-1). Statistically significant relationships (P<0.01 and r>0.70) were observed between Fe and Cu, Cu and K(+), Cu and Ca(2+), B and Na(+), Na(+) and K(+). Assessing the water based on irrigation using Wilcox model showed that some well waters were not suitable for irrigation. Troia water was found to be highly corrosive and the average corrosion coefficients varied from 0.5 to 4.6. According to the Piper and Schoeller diagrams results, the water in Troia was classified as mixed water type.

Identification of surface water-groundwater interaction by hydrogeochemical indicators and assessing its suitability for drinking and irrigational purposes in Chennai, Southern India

“…help to ascertain the usability of water for various purposes. Assessment of groundwater quality in populated regions, including large cities based on drinking water standards have been carried out by several researchers (Sujatha and Reddy 2003;Howari et al 2005;Rao et al 2005;Raju 2007;Ö zcan et al 2007;Umar et al 2009;Gupta et al 2009;Dar et al 2011).…”

Groundwater hydrochemistry of an overexploited aquifer: the case of the Toluca Valley, Mexico

“…This effect might be associated with the increase in bicarbonate ]. According to [8], a k-value  0.25 indicates resistance to corrosion, while higher values are generally more corrosive and can damage the water supply systems. The k obtained data indicated that 2/49 wells in the dry season and 4/49 in the rainy season showed aggressive characteristics.…”

An approach to estimate total dissolved solids in groundwater using electrical resistivity sounding and geochemical methods

“…The issue of ensuring useable water in sufficient quantities to meet the needs of the growing human population has emerged as one of the primary challenge of the 21 st century. Obtaining useful information on groundwater quality of an area is necessary for managing and sustaining the resource for managing and sustaining the resource for various use (Gowd, 2005;Ozcan et al, 2007;Dar et al, 2011).…”
