Water Intrusion

Ground water quality changes or depleting day by day due to various contaminated substances presence in the environment and also other factors influences of excessive drawing of ground water, intrusion of septic sewage, improper dumping of solid waste disposal, untreated industrial effluents, sludge and waste water disposal without giving any treatment and also seasonal changes, etc., all are leads to decrease the quality and depth of ground water table, which leads to cause severe health issues like diarrhea, dysentery, digestive problems etc., on human life. In this contest an attempt has been made to find the ground water quality and also to know the level of contamination presents in Akividu area. About 16 number of ground water samples were collected, which covers the entire area of Akividu, by the estimation of ground water quality parameters includes pH, CO3 , HCO3 , NH3 , NO2 - , DO, Salinity, Hardness, Chlorine ,Total Alkalinity and Total Ammonia, during post monsoon months of October to November 2019. It was found that many of ground water samples have excess amount salinity and hardness and reaming parameters were in permissible range. All these accumulations of salinity (more than 0.5 ppm) and hardness (more than 600 ppm) may cause due to practices of aquaculture near and around the area of Akividu, and hence it is very necessary to done the periodical examination and also need to stop contaminate sources entering into nearby water bodies

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.

Abstract Munroe Island in Kollam District of Kerala is a typical backwater village situated at the confluence of the Ashtamudi backwater and the Kallada river system. It is an amalgamation of eight small islands with a total area of 13.4 sq. km. Salinity intrusion has been a serious threat in the downstream areas of Kallada river for more than one and half decades, affecting the groundwater quality of Munroe Island. The present study focuses on the seasonal variation in physico-chemical characteristics of the underground water system of Munroe island and Kallada river with special reference to saline water intrusion. Physico-chemical analysis of ground water revealed that samples were unsuitable for drinking due to higher content of Na, Ca, and K. Microbiological analysis of island groundwater showed the presence of coliform and E-coli bacteria above the permissible limit. Results indicated a significant correlation between salinity and major anions viz., Cl− and SO42 and cations viz., Mg, Na, Ca, and K of both river surface and island groundwater. In the present study it is clearly evident the occurrence of salt water intrusion in Kallada river from Ashtamudy lake and the its severity become higher during premonsoon season. The results also indicated that the salinity increase in kallada river has a negative impact on island ground water quality. The paper also suggest suitable management strategies for overcoming the salt water intrusion thereby upgrading island sustainability.

This study shows the effect s of solid waste dumpsite on ground water quality in Farin-gida, Kaduna State Nigeria. Water samples were collected from six (6) different wells in three(3) strategic areas that have major dumpsites in Farin-gida. These samples were collected in November from both bore holes and hand dug wells within (0-50 meters) to the dumpsite. The following physico-chemical properties of well water was tested for, in the laboratory thus; Total Dissolve Solid, Total Alkalinity, Fluoride, PH, Turbidity and Electrical Conductivity. The results obtained as shown in table 1,2 and 3 respectively indicate that all the wells have varying levels of physico-chemical concentration that is different from the standard as recommended by World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ), which implies that the water from the study areas are not safe for drinking. Hence, should be treated.

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.
