Abstract.
Earth is a blue planet because of the rudimentary cause of life, that is water. All the biochemical reactions which are pre-requisite for nourishing life of animals and plants, use water as a basic element. Being a universal solvent, it dissolves almost all minerals present in the soil. It is one of the basic and necessary compounds responsible for the survival of life. The main purpose of research was to determine the quality of groundwater in Kasur near the tanneries. The study is focused on the bacteriological and physicochemical (pH, Temperature, DO, BOD, CO2, TOSM, TDS, TM and heavy metals) parameters. We selected four sites as Din Garh, Qatal Garhi, Mangal Mandi and Kot Haleem Khan for investigation. Coliforms were present in high concentration that produce viruses and bacterial diseases such as typhoid fever, hepatitis, gastrocnemii, dysentery and ear infections. World Health Organization (WHO) has justified that the drinkable water must have zero level of coliform and E.coli. Regarding the Total Suspended Matter (TSM), the values ranged from 0.3-0.5g/l in DIN GHARH, 0.2-0.5g/l in QATAL GHARHI, 0.2-0.5g/l in MANGAL MANDI and 0.2-0.6g/l in KOT HALEEM KHAN.
The study concludes that the water pollution due to tanneries in Kasur have changed the bacteriological and physicochemical properties of ground water to a considerable level which is not drinkable. It also conclude that groundwater was contaminated with high concentrations of BOD, TOSM, TDS, TM and Heavy metals due to discharge of industrial effluents.

INTRODUCTION

            Earth is a blue planet because of the rudimentary cause of life, that is water [1]. All the biochemical reactions which are pre-requisite for nourishing life of animals and plants, use water as a basic element [2]. Water is a universal solvent due to its dissolving property. The rule “like-dissolve-like” encompasses water solubility because of its chemical and electrostatic bonding, that is hydrogen-bonding which leads one to comprehend that water is not pure in nature, and it obtains polar-pollutants from its adjacent environment, humans and animals as well as from biological microscopic organisms [3,4,5].

         Being a universal solvent, it dissolves almost all minerals present in the soil. It is one of the basic and necessary compounds responsible for the survival of life [6,7,8,9]. All the basic process including photosynthesis, osmosis, production and transportation are based on water. Water is the only compound which is found below, over and above the surface [10,11].

         Ill-managed urban planning with its huge wastage, is one of major sources responsible for water to get polluted rapidly. There are many other sources which are turning fresh water to turbid like polytene bags, dumping sites, industrial discharge and many others. These sources produce bacteria, viruses and other health hazard factors especially carcinogenic elements [12,13,14,15].

         As being a universal solvent, water plays a crucial role in purgative processes and become coherent with other elements [10,16,17,18]. Such contaminated water transports various unwanted elements to life governing cells that cause many water borne diseases like hepatitis and lung cancer etc[19,20]. As being a lattice of microbial growth, water becomes contaminated with bacterial as well as viral organisms. Bacterias are human friendly at one end but carry harmful diseases at the other end [21,22,23]. Numerous people suffer from different fetal diseases like typhoid, jaundice, diarrhea and diphtheria etc due to water pollution [24].

         Demographic and weather changes affect the water quality and water table [25,26,27]. A variety of activities such as industrial waste, septic tank overflow or leakage of agricultural inputs, pesticides and urban waste are the major sources of groundwater pollution. The tannery is one of the major industrial sectors in Pakistan, which generate considerable amount of polluting materials that are discharged without any treatment into ponds or stagnant pools [28,29,30]. The water bodies receiving such highly polluted effluents are constantly becoming harmful to be used in agriculture, industry and drinking [31,32].

         Throughout the biosphere, people used groundwater for drinking and believed that ground water could be used without any treatment [33]. But now it is proved scientifically that ground water is no more drinkable without treatment because we are fronting with many health hazardous challenges tactlessly grown from water mismanagements, poor drainage system and non-degradable polytene wastages in open places [34,35].

            Pure water yields a healthy life. The availability of pure water has become a major problem for the developing countries like Pakistan [36,37,38]. In this research, the industrious adjoined populated area of Kasur is chosen to study the effect of industrial wastage on ground water [39,40]. The study site has become extra byzantine by total absenteeism of run-off treatment facilities [41]. 

         Logistically, the surface water is unconstrained open water that is not suitable for drinking [42,43]. Unwanted elements including organic, inorganic or biological and bacteriological events e.g. Escherichia coli, coliforms and pseudomonas putida that churlish the water quality [44,45,46,47]. Among the biological pollutants, coliforms, fecal coliform and Escherichia coli are considered as main indicators of fecal contamination [48,49].

         By definition, a coliform is a facultative anaerobe that ferments lactose to produce acid and gas when incubated at 35-37oC and is a gram-negative, non-spore forming rod shaped bacteria [50,51]. Escherichia coli and Entrobacter aerogens are the major representatives of this group. The Most Probable Number (MPN) of coliform and E. coli/100ml of water samples may range from <1 to>1100 which is significant while investigating the water borne diseases [52,53].

            A record of E.coli or either coliform in water samples is an established protocol for assessing the fecal contamination of water sources, storage vessels and nature of pipes transporting water from a treated or untreated water reservoir [54,55]. Clearly it is the contribution of anthropogenic activities higher than the prescribed limit by international standards for human, agrarian and industrial customs [56].

         Organic and inorganic compounds in water, are highly toxic and their toxicity depends upon the electronegativity [57,58]. Along with electronegativity of the elements, polarity also leaves a devasting effect on the nature of ground water because it decides the soft or hard nature of water [59]. Groundwater contaminated with transition metals pose a devasting effect to public health. It is so because transition elements are highly electron donors and also highly toxic as per environmental standards [60,61,62,63].

            As being xenobiotics, the metals including cadmium, beryllium, aluminum, uranium, mercury, lead, bismuth, barium, antimony, arsenic, and so forth are known as toxic metals [64]. The heavy metals emitted by accidental oil spillage and discharged by industries, traffic, municipal wastes, and hazardous waste sites as well as from fertilizers for agricultural purposes are another source of water contamination [63,64,65,66,67].           

         The main purpose of research was to determine the quality of groundwater in Kasur near the tanneries. The study is focused on the bacteriological and physicochemical (pH, Temperature, DO, BOD, CO2, TOSM, TDS, TM and heavy metals) parameters.

MATERIALS AND METHODS

Present research focuses the ground water of Kasur. Groundwater samples were collected from four different locations: Din Garh, Qatal Garhi, Mangal Mandi and Kot Haleem khan. The water samples were collected at the same day with the difference of ten to fifteen minutes. About eighty groundwater samples were taken in sterilized glass bottles of 1000ml and immediately processed to compute temperature, pH, and Dissolved oxygen (DO). Same water samples were taken in another sterilized glass bottles of 500c.c which were brought to the laboratory for further analysis. One of the two bottles, was processed for Biological oxygen Demand (BOD) measurements while the other processed for determination of different bacteriological and physicochemical parameters. Carbon dioxide, Total Suspended Matter (TSM), Total Minerals and Total Organic Suspended Matters (TSOM) were computed by standard method. Sterile bottles are capable to prevent the accidental contamination of the water while its transportation to laboratory.

All the human activities which take part in economic growth, either these are industrial, agrarian, fabric or fashion, these all affect groundwater badly. Current research was conducted in four different residential areas of Kasur. Kasur is an industrial city where physical, chemical and microbiological properties of groundwater had been changed due to anthropogenic activities during recent decade. People use ground water for drinking and for irrigation to their crops. In present study, 80 groundwater samples were collected from four different areas and different parameters (pH, Temperature, BOD, DO, CO2, TDS, TOSM and Heavy metals) were used to check the physicochemical and bacteriological contamination of groundwater. The physiochemical and bacteriological parameters of ground water were observed changed while making a comparative analysis with previous studies conducted in Kasur. The results show that the ground water of study site was polluted with physiochemical elements like heavy metals. Groundwater temperature was computed using a glass thermometer that ranged from 25-26ºC in DIN GARH area, 23-26ºC in QATAL GARHI area, 25-26ºC in MANGAL MANDI and 25-26ºC in KOT HALEEM KHAN area. The temperature values are within the permissible limits set by National Environment Quality (NEQS) so it can be used for irrigation purpose.

The pH of groundwater ranged between 7.5-7.9 in DIN GHARH, 7.5-8.0 in QATAL GHARI, 7.5-7.8 in MANGAL MANDI and 7.7-8.0 in KOT HALEEM KHAN. The pH of groundwater was observed neutral to alkaline in nature. These values of pH are within limit set by NEQS for pH that is 6-10.

The DO values were measured which were from 6.198-7.036 mg/l in DIN GHARH, 6.254-7.370 mg/l in QATAL GHARHI, 6.757-7.370 mg/l in MANGAL MANDI and 6.199-7.091 mg/l in KOT HALEEM KAN. There was a gradual decrease in DO values when computed after a temporal window of 5 days. The decrease in DO value ranged from 3.573-4.411mg/l in DIN GHARH, 3.573-4.132mg/l in QATAL GHARHI, 3.797-4.355mg/l in MANGAL MANDI and 3.462-4.132mg/l in KOT HALEEM KHAN. The decrease in the DO values after 5 days of respiration for first sampling might be due to elevated level of fecal bacteria. The DO concentration for groundwater ranged from 1.7mg/l-6.7mg/l according to international standards.  Dissolved oxygen (DO) is the most important factor in the assessment of water quality. Suitable DO is energetic for aquatic life.

The BOD values of groundwater samples were ranged from 2.458-3.519 mg/l in the study areas. High levels of BOD in study area was due to industrial effluents containing huge amount of organic matter. Biological oxygen demand trials the recyclable materials in water and helps in the growth of bacteria and other organic by-products.

The values for CO2 were ranged from 0.616-1.144mg/l in DIN GHARH, 0.704-1.232mg/l in QATAL GHARHI, 0.616-1.232mg/l in MANGAL MANDI and 0.616-1.232mg/l in KOT HALEEM KHAN. Unlike oxygen, CO2 enters into chemical combination with water to form H2CO3, which in turn reacts with available limestone to form CO2 and bicarbonates.

Coliforms were present in high concentration in the complete study site. MPN values ranged from 20 to >1100 in all the groundwater sample sites. When the groundwater samples were processed for the coliform estimation, contaminants were found in all the samples of research areas restricted more than >1100 MPN. In fact, this value is in maximum range as per normal.

Coliform bacteria remain active in human and animal wastes. The bacterial contamination in ground water is studied by coliform test in water drainage system. The presence of coliform bacteria in groundwater indicates the mixing of surface water with ground water. Viruses and bacterial diseases such as typhoid fever, hepatitis, gastrocnemii, dysentery and ear infections can be contracted in water with high fecal coliform counts. World Health Organization (WHO) [67]has justified that the drinkable water must have zero level of coliform and E.coli. In this research it is justified that ground water of Kasur area is contaminated with fecal coliforms.

Regarding the Total Suspended Matter (TSM), the values range from 0.3-0.5g/l in DIN GHARH, 0.2-0.5g/l in QATAL GHARHI, 0.2-0.5g/l in MANGAL MANDI and 0.2-0.6g/l in KOT HALEEM KHAN. The nature of TSPM includes settleable particles, which require more than 6hrs. For the total minerals (TMs), more or less the same pattern was observed.  WHO further designates the limit of TDS in drinking water that is 1000 mg/L however, high TDS concentration indicates that various minerals and solids have been dissolved in groundwater. High concentration of TDS governs the remarkable changes in water that effect the taste, hardness and corrosive property of the water. High TDS concentrations are due to the presence of bicarbonates, carbonates, sulphates, chlorides and calcium, which may originate from natural sources, sewage, urban runoff and industrial wastewater.

Total Organic Suspended Matter (TOSM) values of all the groundwater samples were ranged from 0.1-0.4g/l in DIN GHARH, 0.1-0.3g/l in QATAL GHARHI, 0.1-0.3g/l in MANGAL MANDI and 0.1- 0.5g/l in KOT HALEEM KHAN. High concentration of organic carbon states high concentration organic compounds as contaminants.

Atomic Absorption Spectrophotometer was used for the detection of heavy metals which resulted that both, surface and ground water are contaminated with heavy metals. The limits prescribed by WHO for toxic metal production as residual of industries is much lower that is in groundwater available in Pakistan. Both surface and groundwater are sponsors of heavy metals. Many of these metals are important in trace amount of human health. However, in higher amounts they cause water pollution and can be toxic causing serious health issues. Arsenic (As) and Zinc (Zn) are heavy metals which were found in the groundwater of Kasur.

The concentration of As in ground water was observed as 24-52 mg/L. Arsenic concentration vary widely in this groundwater. However, the chronic intake of high arsenic value in groundwater would potentially cause health hazards in future over a long-range period, since this element is reduced into arsenic, which is accumulated in the human body and arsenic is more difficult to remove from drinking water supplies than arsenate. The results show that the value of Zn was ranged from 0.21-0.74 mg/L in DIN GHARH, 0.68-1.12 mg/L in QATAL GHARHI, 0.54-0.95 mg/L in MANGAL MANDI and 0.38-0.94 mg/L in KOT HALEEM KHAN. The chronic drinking of additional Zn in water include severe gastrointestinal effects. Diminished immune function, vicissitudes in lipoprotein and cholesterol levels, abridge copper status and Zinc iron interactions.

CONCLUSION

The study concludes that the water pollution due to tanneries in Kasur have changed the bacteriological and physicochemical properties of ground water to a considerable level. Groundwater was contaminated with high concentrations of BOD, TOSM, TDS, TM and Heavy metals due to discharge of industrial effluents. The continuous release of agricultural runoff, untreated industrial discharges and drainage are the major causes of groundwater pollution in Kasur.
