“…The PC1, which explains 24.7 % of the total variance, consists of Li, B, Mn, Fe As, and Si. Trace elements in groundwater should reflect the physical and chemical characteristics of the groundwater such as local temperatures, groundwater sources, chemical compositions of aquifer materials and weathering reactions (Tanji and Valoppi 1989). Among them, the chemical composition of the rock, one of the major aquifer materials, was reported as one of the major factors influencing groundwater chemistry (White et al 1963).…”

A rapid increase in the use of ground source heat pump (GSHP) systems for heating and cooling of buildings potentially threatens to harm shallow groundwater quality. As a necessary preliminary step toward evaluating GSHP impact on shallow groundwater quality, this study used multivariate statistical analyses to investigate characteristics of trace elements in groundwater in Fuchu city in western Tokyo Metropolis. Water samples were collected twice a month from two aquifers at 30-and 45-m depths using four observation wells for more than a year. Concentrations of 14 trace elements (Li, B, Al, Cr, Mn, Fe, Ni, Cu, As, Se, Sr, Cd, Sb, and Pb) and Si as well as oxidation-reduction potential (ORP), dissolved oxygen (DO), electrical conductivity (EC), and pH were measured. All elements were under the environmental water quality criteria issued by the Japanese Ministry of the Environment. No clear seasonal trends were observed in the concentrations of 15 elements in groundwater. Principal component analyses showed the element properties were well characterized by three principal components (PC). PC1, which represents the more mobile trace elements in the groundwater, consisted of Li, B, Mn, Fe, As, and Si. PC2 included Al, Ni, Cd, and Sb, and represents ORPinsensitive properties. PC3 consisted of Pb, Cu, and Se, which are less mobile in groundwater. Samples collected from the same aquifer had high similarity in distribution and variation of the trace elements. This study proposes a useful statistical platform for assessing future effects of GSHP systems on shallow groundwater quality.

“…Analysis of trace elements indicated that cationic trace elements (mainly trace metals) tend to be strongly retained by earth materials owing to ion exchange, sorption and mineral solubility, and do not typically accumulate to very high concentrations in groundwaters; the exception being shallow soil profiles with coarsetextured soils and large water fluxes. Anionic trace elements (mainly oxanions), although retained by earth materials (clays and sesquioxides) to some extent, are subject to greater mobility and may accumulate to high concentrations groundwaters (Tanji and Valoppi, 1989). The recent study explains that a better understanding of the environmental impacts of fly ash disposal or utilization and the solubility characteristics of various chemical species associated with fly ash were examined previously and summarized in Tables VII and VIII (Bayat, 1998).…”

In this work, trace metals such as Hg, Pb, As, Cd, Cu, Fe, Mn and Zn in underground water samples obtained from three wells, an ash-pond and drinking water located near the Yatagan Thermal Power Plant were measured. As, Hg, Cu and Zn contents of the underground water were lower than those reported in the EEC (European Economic Community) and WHO (World Health Organization) guidelines. In contrast, the levels of Fe, Pb, Cd and Mn in some groundwater samples were higher than EEC and WHO guideline values. The trace metal concentrations in coal ash-pond water were observed to be lower than water quality standards with the exception of Pb. The obtained results indicated that the trace metal concentration in the sampled drinking water site did not exceed WHO limits.

“…The only exception was the higher degree of lead accumulation (Roszak, 1987). Heavy metal accumulation was also lower, sometimes much lower, than in the shallow ground waters of California (Tanji and Valoppi, 1989).…”

Abstract. In the period 1984-1990 the following vegetables were grown: red beet, carrot and parsley in four allotment gardens of Ptock city (Central Poland), situated near the refinery and petrochemical works. Cadmium, lead, copper, chromium, zinc and manganese concentrations were determined in the leaves and roots of vegetables, The heavy metal accumulation in the soil, dustfall (measure of air pollution), and ground water was determined. The quality of the vegetable yield, notably of the leaves, was low. This was mainly due to the excessive chromium and cadmium content in the leaves. Accumulation of heavy metals was relatively low in the soil, rather high in the ground water and variable in the dust.
