“…Current studies on coastal carbonate aquifers throughout the world are undertaken in aquifers with lower nitrate concentrations than those of the Daweijia area. For example, NO 3 − concentrations are less than 265 mg/L in groundwater from carbonate aquifers along the Mediterranean coast (Schiavo et al, 2006;Ghiglieri et al, 2012), less than 80 mg/L along the Gulf of Mexico (Andrews, 1994;Katz, 2004;Katz et al, 2004), and less than 20 mg/L along the Caribbean coast (Mutchler et al, 2007;Young et al, 2008;Null et al, 2014). In the coastal carbonate aquifer of the Daweijia area, NO 3 − concentrations are characterized by high values reaching 521 mg/L.…”

“…In the coastal carbonate aquifer of the Daweijia area, NO 3 − concentrations are characterized by high values reaching 521 mg/L. The major ion geochemistry of groundwater in coastal carbonate aquifers has been used in conjunction with multiple environmental tracers (e.g., δ C) for defining the recharge patterns of karst aquifers (including recharge origin, amount and distribution) (Jones et al, 2000;Horst et al, 2008;Charideh and Rahman, 2007;Frot et al, 2007;Murad et al, 2011;Khaska et al, 2013), building hydrogeological conceptual models (Falcone et al, 2008;Frondini, 2008;Long et al, 2008;Cerar and Urbanc, 2013), assessing possible anthropogenic influences on groundwater Schiavo et al, 2006;El Yaoutia et al, 2009;Urresti-Estala et al, 2015) and estimating the residence time of younger groundwaters and flow rates (Katz, 2004;Horst et al, 2008;Ettayfi et al, 2012). In this study, we report the major chemical and δ H and CFC compositions of groundwater from the coastal aquifers in the Daweijia area of Dalian City, north-eastern China.…”

• Examine high nitrate contents in the coastal carbonate aquifer of northeast China • Estimate renewal rates and mean residence times of groundwater in coastal aquifers • Evaluate the relation between groundwater age distribution and nitrate transport • Propose potential pollution patterns of nitrate distribution in the coastal aquifer • Identify anthropogenic input mainly responsible for increasing groundwater salinity a b s t r a c t a r t i c l e i n f o H and CFCs methods were applied to provide a better understanding of the relationship between the distribution of groundwater mean residence time (MRT) and nitrate transport, and to identify sources of nitrate concentrations in the complex coastal aquifer systems. There is a relatively narrow range of isotopic composition (ranging from − 8.5 to − 7.0‰) in most groundwater. Generally higher tritium contents observed in the wet season relative to the dry season may result from rapid groundwater circulation in response to the rainfall through the preferential flow paths. In the well field, the relatively increased nitrate concentrations of groundwater, accompanied by the higher tritium contents in the wet season, indicate the nitrate pollution can be attributed to domestic wastes. The binary exponential and piston-flow mixing model (BEP) yielded feasible age distributions based on the conceptual model. The good inverse relationship between groundwater MRTs (92-467 years) and the NO 3 − concentrations in the shallow Quaternary aquifers indicates that elevated nitrate concentrations are attributable to more recent recharge for shallow groundwater. However, there is no significant relationship between the MRTs (8-411 years) and the NO 3 − concentrations existing in the carbonate aquifer system, due to the complex hydrogeological conditions, groundwater age distributions and the range of contaminant source areas. Nitrate in the groundwater system without denitrification effects could accumulate and be transported for tens of years, through the complex carbonate aquifer matrix and the successive inputs of nitrogen from various sources.

“…Quality of groundwater is equally important to its quantity owing to the suitability of water for various purposes [8,9]. Groundwater chemistry, in turn, depends on a number of factors, such as general geology, degree of chemical weathering of the various rock types, quality of recharge water and inputs from sources other than waterrock interaction.…”

“…The groundwater quality is as important as its quantity owing to its suitability for various purposes (Schiavo et al 2006;Subramani et al 2005). Assessment of hydrochemical quality of groundwater systems is usually based on the availability of a large amount of information concerning groundwater chemistry (Afzali et al 2014;Naseem et al 2011;Aghazadeh and Mogaddam 2010;Hossein 2004).…”

Hydrogeochemical investigation of groundwater resources of Kashipur Block, Purulia district, West Bengal has been carried out to assess the water quality for domestic and irrigation uses. Twenty groundwater samples were collected and analyzed for pH, electrical conductivity, total dissolved solids, hardness, major anions (CO 3 2− , HCO 3 − , Cl − , SO 4 2− , F − ) and cations (Ca 2+ , Mg 2+ , Fe 2+ , Na + , K + ). Study results reveal that the groundwater of the area is mostly acidic in nature. The trend amongst average ionic concentrations of cations and anions is Mg 2+ > Ca 2+ > Na + > Fe 2+ > K + and Cl − > HCO 3 − > CO 3 2− > SO 4 2− > F − respectively during the post monsoon whereas the trend for cations and anions are Mg 2+ > Ca 2+ > Na + > K + > Fe and Cl − > HCO 3 − > SO 4 2− > F − > CO 3 − in pre monsoon session, respectively. To explore the ionic toxicity of the study area, the derived parameters like sodium adsorption ratio, soluble sodium percentage, residual sodium carbonate, magnesium adsorption ratio, Kelly's ratio and permeability index were calculated. The hydro geochemical data suggest that weathering of rock forming minerals along with secondary contributions from agricultural and anthropogenic sources are mainly controlling the groundwater composition of Kashipur Block, Purulia District. According to piper diagram, water samples of most of the area of the block are fresh water and in some areas sulphate rich throughout the year. All samples are distributed to central rock dominance category. Groundwater chemistry of this block is mainly controlled by the interaction existing between the litho units and the percolating water into the subsurface domain. However, the groundwater quality and suitability of this study area can be termed as good to moderate with a few exceptions which have been encountered on a local scale.
