The groundwater present in the hard rock region of the dry zone of Sri Lanka is made up of the shallow 'Regolith Aquifer' and the deeper fracture zone aquifer is now clearly recognized. However, up to now no study had been carried out or reported in this country on the dynamic nature of this shallow regolith aquifer. This is the very first study carried out and reported in this regard. As part of the study, the impact of the Mau Ara trans-basin canal on the groundwater conditions below the area of influence of this trans-basin feeder canal has also been examined.

The groundwater of Gwalior region was assessed for its irrigational suitability. Fourteen water samples collected from dug-cum bored wells tapping shallow to deep aquifers from the clay with Kankar, silt, sandstone were used. The Groundwater samples were analyzed for major cations: Na+, Ca++, Mg++, K+,and anions: Cl-,HCO3-, CO3- -, SO4- and NO3-. The important constituents that influence the water quality for irrigation are total dissolved solids (TDS), electrical conductivity (EC), sodium adsorption ratio (RSC), sodium percentages (Na%) and permeability index (PI). These parameters were compared with standard limits and were found to be within the safe limit suitable for irrigation purpose. In addition the total dissolved solids in ground water ranged between 256-1324 mg/l during the investigation period, revealed that irrigation using groundwater of the study area would not cause salinity hazards.

Water scarcity in agriculture sector forced farmers to use city wastewater without any regard of its quality effects on environment and resultant contamination of soils and plants, particularly with heavy metals. A survey of effluent, tube well and canal water irrigated areas in Faisalabad, Pakistan was conducted to appraise Cd concentration in these waters and soils, and its uptake by cereal and legume crops. Water, soil and plant (seeds, shoot & roots) samples were collected and analyzed for Cd concentration. Results illustrated that wastewater contained 11.0 and 3.7 times higher Cd than tube well and canal waters, respectively. Location-wise the lowest Cd concentration was 0.6 µg L-1 at Bypass Samandari Road (BSR) while the highest was 1.4 µg L-1 at Malkhanwala (MW). Maximum AB-DTPA extractable Cd (0.30 mg kg-1 & 0.248 mg kg-1) was found in soil samples collected from 0-15 cm depths at Uchkera and Ghulam Muhammad Abad (GMA), respectively. It was the lowest (0.04 mg kg-1) in soil samples collected from Chak No. 235/RB (C235) location. Long term effluent irrigation resulted in 248 and 260% increase in Cd contents at 0-15 cm depth of soils compared to tube well and canal waters irrigated soils, respectively. In all the cases, Cd was within safe limits. About 70% of the metal was deposited in upper 30 cm layers. Seeds of effluent irrigated chickpea acquired the highest concentration of Cd (0.177 mg kg-1), while was the lowest in wheat seeds (0.034 mg kg-1). Concentration of Cd was higher in mungbean shoots (0.62 mg kg-1) than in wheat shoots. The order for Cd concentration in seeds was chickpea > maize > mungbean > wheat for wastewater irrigated crops. Similar trend of Cd concentration was observed in tube well and canal waters irrigated crops.
