This study was conducted to assess the effect of wastewater quality of Paharang drain Faisalabad on ground water quality of adjacent areas. Ground water samples and drain water samples were collected and analyzed by using standard methods. Parameters of wastewater samples were compared with Pakistan National Environmental Quality Standards (NEQS). Results indicated that physico-chemical parameters including pH, total dissolved solids (TDS), chloride, fluoride and total hardness were found exceeding the permissible limits in wastewater samples. Similarly, few physicochemical parameters in groundwater were found within the permissible limit while electrical conductivity (EC), TDS, chlorides (Cl), fluoride (F), and total hardness in most of samples were found above the Pak EPA and WHO standard limits. Heavy metals like nickel (Ni), chromium (Cr), iron (Fe), lead (Pb), and arsenic (As) were found within the prescribed concentrations in drain and ground water samples. Statistical analysis showed significant effect of some drain wastewater parameters like conductivity, TDS, salt, temperature, and Cl on the corresponding ground water quality. A strong positive correlation between pH, EC, TDS, Salt, and Cl in drain wastewater and strong positive correlation between EC, TDS and Salt in ground water samples was observed. For improving the ground water quality in the adjacent areas textile wastewater treatment all factories is required, and a combined effluent treatment plant (CETP) at the Paharang drain is also recommended.

Ground Water Quality

The quality of coastal ground water on small islands has characteristics that are influenced by environmental and area factors. Yeben Island is a small island with an area of 0.57 km2 with priority coastal and marine tourism areas in the islands of Raja Ampat. This study aims to (1) analyze levels of ground water quality parameters and (2) analyze water samples against water quality standards. Groundwater samples taken as many as 4 samples from the study location. The location of water samples is in the morphology of the coastal plain. The analysis of each physical and chemical parameter of each groundwater sample is carried out by comparing the value of drinking water quality standards. The results are presented in a comparison table of quality standards and a graph of scaled values.Based on the results, the laboratory shows that it exceeds the quality standard of physical elements and chemical elements including fluoride, hardness, sulfate and organic substances. In general, the quality of water is poor. Poor ground water quality occurs due to the influence of sea water intrusion.

Due to industrialization and over population, surface water resources are out of reach from many people so consumption of ground water is the only choice to overcome the water scarcity. Naturally, ground water is one of the significant and potable water resource but some geographical conditions and anthropogenic activities deteriorate the water quality and make it objectionable for drinking. This study was conducted to evaluate the ground water quality of Karachi, Pakistan. For this, 42 ground water samples were collected from different districts of Karachi and analyzed their physicochemical and microbiological characteristics and compared with both international (WHO) and national (SEQS) drinking water standards. Observations of the study declared that overall contamination (physicochemical and microbial) in the ground water samples of different districts of Karachi was as follow West (21%), South (20%), Central (17%), Malir (16%), Korangi (14%) and East (12%). Physical assessment of the study area declared that pH and turbidity of the ground water samples varies in the range of (6.54-7.9) and (0-1.01 NTU) which exist in the standard prescribed limit. Whereas, detection of chemical contaminants particularly TDS (457-12090 mg/L), hardness (118.8-3645 mg/L) and chloride (190-4918 mg/L) content in most of the samples were also exceed from the prescribed limit. Additionally, arsenic was abundantly present ranging from 3.52-13.63 mg/L in all collected samples of Karachi city while the concentration of cadmium (range: 0.0005-0.5012 mg/L) and lead (range: 0.201-1.817 mg/L) were also high in few samples, from the permissible limit of drinking water. Microbial contamination was also detected in which coliforms were present in the range of 0-150 CFU/100mL, which also unfit the water quality. This deteriorated ground water quality of Karachi can be improved by maintenance of proper sanitary conditions of the communities and implementation of water treatments, otherwise consumption of such water may develop serious health related consequences in the consumers.

Ground water quality of Horticultural College and Research Institute (HC & RI), Periyakulam located in Theni District, Tamil Nadu was assessed during January 2021. Ground water samples were collected from bore wells and their quality parameters were assessed. pH values ranged from 6.88 to 7.81; electrical conductivity values ranged from 0.20 to 1.28 dSm-1 and most of the samples were under high salinity class (C3) (84.6%). Calcium, magnesium, sodium and potassium content ranged from 1.68 to 4.72 m.e L-1, 0.72 to 10.6 m.e L-1, 1.35 to 10.3 m.e L-1 and 0.05 to 0.23 m.e L-1 respectively. Most of the samples were found to be magnesium dominating and magnesium exceeds the calcium content in most of the water samples. Magnesium toxicity will be exhibited in the continuous use of water to crops. No carbonates were noticed. Bicarbonates, chloride and sulphate concentration varied from 2.0 to 13.4 m.e L-1 , 1.12 to 7.52 m.e L-1 and 0.02 to 0.99 m.e L-1 respectively. The sequence of cations were found in the order of Mg2+ >Na+> Ca2+ >K+ and anions followed the sequence of HCO3- >Cl- > SO42-. Total hardness in the study area varied from 120 to 686 mg L-1 and majority of the samples (61.5 %) were very hard. RSC values varied from -3.76 to 5.24 meL-1 and most of the samples come under the moderate category (61.5%) followed by safe (38.5%). RSBC varied from 0.32 to 9.48 m.e L-1 and majority of the samples come under the safe category (61.5%) followed by unsafe (23.1%) and moderate (15.4%). SAR values ranged from 0.83 to 5.11 and all the samples were found to be low sodium category (S1). There is no sodicity problem existing in the ground waters. In the present study, the permeability index ranged from 39.4 to 80.3 per cent and the majority of the samples come under the permeability hazard class II, which can be used for irrigation without any permeability problem in the soils. As per CSSRI, Karnal classification, majority of the ground water samples coming under good (76.9), followed by marginally alkaline (15.4%) and alkaline (7.7%). Marginally alkaline and alkaline waters should be managed carefully to avoid a negative impacts on soil and crops.

Present study is carried out for the assessment of ground water quality and comparing its suitability for drinking purpose in Ambur city in Tirupattur District, Tamil Nadu, India. Water quality index is calculated on the basis of pH, conductivity, total dissolved solids, total hardness, Ca2+, Mg2+, Na+, K+, Cl-, alkalinity, and SO42- content of the water samples. Water quality index study show that the ground water quality of the study area is deteriorated due to high value of total dissolved solids, conductivity, total hardness, calcium, magnesium, chloride, and sulphate in water samples.

AbstractUranium concentration in the ground water samples from the district of Tiruvannamalai, Tamil Nadu, was measured using an LED fluorimeter. All the samples were qualified as potable water from the radiological perspective. Though some samples showed mild chemical toxicity, they are still safe for ingestion. Different risk coefficients were calculated, and they were compared with recommended safety limits specified by various agencies. Software tools such as QGIS 15, GraphPad Prism 8 and Surfer 15 were employed for developing maps and plots.
