508.55 K m

Sindh province covers 17.7% of the total land area of Pakistan and has about 23 % of total the population of country, on globe it is located between 23o 35‘to 28o 30‘ North latitudes and 66o 42‘and 71o 1‘East longitudes. The entire region forms the southern part of Pakistan, physiographically called "Lower Indus Plain". The length of the region from North to South is about 508.55 kilometers and nearly 436 kms at east to west, covers 140,915 square kms (Fig.1). Sindh province is bounded by Punjab province at North, Balochistan province at West, India at East and Arabian Sea at South. Geographically Sindh has 241.395 kilometers of the coastal strip in the south-west along the Arabian Sea. In the extreme west of 436.13 Km Sindh is the mountainous region consisting of the Kohistan section of barren Kirthar Mountains. To the east is the sand belt stretching from Bhawalpur to the Run of Kutch/Kachh and between these Fig1. Shows the Physiography of Sindh Province tracts lies the Indus Valley terminating in the deltaic area in the south-west, except for a small hilly (Nagarparkar) tract in the South East corner of the Tharparkar District (Fig. 1). Geomorphologically lower Indus plain is formed by alluvial deposits carried by river Indus and its tributaries and is underlain by an unconfined aquifer. In Sindh about 28% of the area is underlain by fresh Supplemental irrigation. The quality of groundwater and surface-water is low and is further deteriorating because of unchecked disposal of untreated municipal and industrial wastewater and excessive use of fertilizers and insecticides. The estimated ground water resource in the province varies between 13 to 16.2 MAF with an estimates safe yield between 4.4 to 8.1 MAF (UNITAR, 2004). The groundwater resources are under the threat of seawater intrusion caused by groundwater overdraft. On the basis of agro-ecology Sindh province is divided into three main zones (Fig. 3), two of which are JACOBABAD A1 e - SHIKARPUR further divided into sub-zones as: n Zone- B1 Zo SUKKUR LARKANA Zone-A: The Right Bank of river Indus (upper Sindh). KHAIRPUR - Sub-Zone A1 Main area - Sub-Zone A2 Piedmont soil region DADU Zone-B: The left bank of river Indus. SANGHAR - Sub-Zone B1 Guddu Barrage command area - Sub-Zone B2 Sukkur Barrage command area MIRPUR KHAS HYDERABAD Zone-C: Lower Sindh. UMARKOT In addition to the above three agricultural KARACHI THATTA BADIN zones, there are two more zones in Sindh i.e., zone-D Zone - C is a desert area in the east of Sindh, and zone-E is the western hilly zone. The fresh ground water is only available in zone- A and zone-B, however, in zone- C, zone- D and zone- B fresh ground water is very limited. Fig.2. Shows the agro-ecological zones of Sindh The climate of Sindh is arid and hot, mean annual precipitation is 140 mm. In the last eleven years the rainfall varied from a low of 23 mm to a high of 468 mm. Overall rainfall is scarce, erratic and unpredictable. The mean annual maximum and minimum temperatures are 35oC and 19oC, respectively. The maximum daily temperature commonly exceeds 45oC in April through June. e

INTRODUCTION Water is a great gift of nature, there is a common saying “No life without water” it is universal solvent and is a major constituent of all living organisms. Ground water pollution is usually traced back to four main origins viz, Industrial, Domestic, Agricultural and over exploitation (Anil & Musadique, 2005). The quality of water whether it is used for drinking, irrigation or recreational purposes, is significant for health worldwide. Water quality can have a major impact on health, both through outbreaks of waterborne disease and by contributing to background rates of disease (Lorna & Jamie, 2002). Water for drinking purpose should have good smell, taste, and should be free from contaminants that are harmful to health. Thus the domestic water should be low in hardness and sediments; however industries require the water quality according to their nature. All water from natural sources contains dissolved substances and their presence in water can result from either natural processes or human activities. The water shortage and its increasing competition for various uses badly affected its quality. Most of the reported health problems are directly or indirectly related to water, the only way to know; its use for drinking and cooking contains potentially harmful substances is to have it tested. To determine safety, the contaminant concentrations in the water are compared to maximum contaminant levels (MCLs) established by the world Health organization (WHO) for public drinking water supplies in accordance with the Safe Drinking Water Act. In current study 245 water samples were collected from the hand pumps and Dug-wells at different localities i.e., Jamshoro, Dadu, Larkana, Shikarpur, Kamdar at Shahdakot, Jacobabad, Kashmore, Ghotki, Sukkur, Khairpur, Nawabshah, Sanghar, Umerkot, Mirpur Khas, Tharparkar, Badin, Thatta, Tando Mohammad Khan, Hyderabad, Mitiari and Tando Allahyar districts of the province in for the assessment of the ground water quality. It was observed during study that the hand pumps are mostly installed at the depth of about sixty feet, but information about the exact depth is not known, even to the owners. It is also observed that the quality of ground water is better in the samples collected near river Indus. During field it is notified that most of the cities and towns are using ground water rather than surface, however, almost all the rural communities are using ground water for domestic purpose except the areas where the ground water is brackish as: Mithi, Islam Kot, Thatta and Badin which are using surface water. Manghand town is also using surface water, no hand pump or well was seen during field, people informed that ground water is brackish, while the town is located near the bank of river Indus. Plate.1. Showing on the spot testing of Physical pH, electrical conductivity, salinity and total parameters of ground water during field dissolved solids were analyzed on the site during sample collection, while As, Cd, Pb, Zn were analyzed from the laboratory of NCE in inorganic chemistry university of Peshawar. The perceived data is compared with recommended drinking water quality standards of WHO and US environmental protection agency.

GROUNDWATER QUALITY OF DIFFERENT DISTRICTS IN SINDH To asses the groundwater quality all the districts of Sindh province were surveyed except Karachi division. The process of drawing sample up from the aquifers makes variation in the chemistry of water, therefore, vigilant procedure was considered mandatory during the collection of water samples. To avoid any possibility of contamination the bottles used for the collection of water samples were treated with 5% HNO3 and then rinsed with deionized water. Two bottles of water were filled from the sample site, among these the water of one bottle was acidified by adding few drops of HNO3 and the other was kept un-acidified. The water of un-acidified bottle was analyzed for the determination of, temperature, pH, electrical conductivity and total dissolved solids (TDS) at the site and the water of the acidified bottles was kept for analysis heavy metals. The collection of groundwater samples was planned as follows: a.

Selection of various representative spots in the field, where by the quality of water could possibly be affected. Collection of limited number of samples that could be representative about the contamination and other factors involved. b. Checking of accuracy and precision of the laboratory analyses by other techniques. The purpose of which is to assure that the analytical result reported by the laboratory accurately express the actual concentration of the solutes in the water, as it existed in the field. c. It was decided that total 245 water samples will be collected from the all the districts of Sindh except Karacki area. The detailed analysis groundwater account of all the districts is given below. The perceived data is compared with international standards for drinking water recommended WHO (2004) and US-EPA (2006). Arial distribution and concentration of elements is also given in both contour and relief map. The possible sources of contamination as well as remedial measures are also given in discussion. Determination of pH pH is one of the important abiotic factors that serves as an index for water pollution. No health based guideline value is proposed for pH, but it is one of the most important operational water quality parameters. An increased concentration of carbon dioxide will lower the pH and vice versa. The direct effects of exposure of humans and animals to extreme pH values (below 4 or above 10) for extended periods of time may result in irritation to the eye, skin and mucous membranes (Shastri, 2005). Fig. 3. Shows the pH level at difefrent area of Sindh 9

The instrument used for determination of pH level in ground water is WTW info-lab pH meter. The maximum contamination level of pH in normal drinking water is 6.5 - 8.5 (WHO, 2004) annexure (2). 86 water samples different localities of Kashmore, Jacobabad, Shikarpur, Larkana, Dadu, Jamshoro and Thatta districts at right bank of river Indus were collected; the samples were collected from hand pumps mostly and the water of these hand pumps is used for drinking purpose. Details of the sample collection area are given below: 07 water samples were collected and analyzed from Kashmore district for pH level; the samples were collected from Ghospur, Kandhkot, Kashmore city at south, Kashmore city at north, Guddu, Darkhan and Risaldar. 10 samples from Jacobabad district were collected at Ramzanpur, Abad, Mirpur, Maulabad, Dil Murad, Jacobabad city east, Jacobabad city center, Jacobabad city North, Thul and village Karim Bux. While from Shikarpur district 06 water samples were collected at Garhi Yaseen, Shikarpur city south, 8.5 8

CHEMICAL PARAMETERS OF GROUNDWATER IN SINDH The detail geochemical study of Lead (Pb), Cadmium (Cd), Aresnic (As) and Zinc (Zn) in groundwater is determined. Nowadys heavy metal pollution is a great problem to environment. The groundwater contamination particularly by the industrial effluents (hevymetals) and their persistence in food chain has been major concern. As these are bio-accumulative and relatively stable as well as toxic/ carcinogenic and there four require close monitering. To asses the Pb, Cd, As, and Zn in groundwater samples were collected from different locations of Sindh province, due to limited resources three to four representative samples from every district were collected totling 82 samples. Mr. Muhammad Waseem PhD., Schlor carriedout analytical work at NCE in Inorganic Chemistry, university of Peshwar on the instrument Electro thermal Atomic Absorption. The obtained data is discussed below, while the healthaffects are given in Annexue 1. Arsenic (As): Arsenic occurs naturally in rocks and soil, water, air, and plants and animals. It can be further released into the environment through natural activities such as volcanic action, erosion of rocks and forest fires, or through human actions. Higher levels of arsenic tend to be found more in ground water sources than in surface water sources. The demand on ground water from municipal systems and private drinking water wells may cause water levels to drop and release arsenic from rock formations. Human exposure to arsenic can cause both short and long term health effects. Short or acute effects can occur within hours or days of exposure. Long or chronic effects occur over many years. Long term exposure to arsenic has been linked to cancer of the bladder, lungs, skin, kidneys, and nasal passages, liver and prostate. The maximum allowable limit of As in drinking water is 10 µg/l. The concentration of Arsenic is found high above the permissible limits at Maripur Mathelo 24.53 µg/l, at Rohri city 66.11 µg/l, at Sukkur city 46.93 µg/l, at Dadu city east 216 µg/l, at Tando Mohmmad Khan II 74.04 µg/l, at Mirpur Bathoro 73.34 µg/l, at Diplo 137.8 µg/l, at Nagarparkar 20.67 µg/l, at Bhalwa 20.42 µg/l, at Tandojam 20.31 µg/l, at Nawabshah I 17.29 µg/l and at Sanghar I 20.19 µg/l, and it is alaraming condition in above areas. However, rest of the groungwater sample showed Arsenic contents within the permissible limit. The data would be different if the number of sample could be collected more than three or four from every district. The obtained data is presented graphicall (Table.2; Fig. 5). The aerial distribution of Arsenic is shown through contour map and relief map in Figure. 6 & 7. Cadmium (Cd): Cadmium occurs naturally in Zn, Pb, Cu and other ores which can serve as source to ground and surface water. Cd can be relesed in drinking water fron corrosion of some galvanize plumbing and water main pipe material. Average concentration of cadmium in dinking water is (10 µg/l) 0.005mg/l (WHO, 2004). It can cause the health hazards such as nausea, vomitimg, diarrhea, muscle cramps, salivation, semsry disturbances and renal failure. The long term Cadmium exposure can cause certain effects such as kidney, liver, bone and blood damage problems. The concentration of cadmium in ground water is found higher in all the parts of Sindh province. In district Jamshoro: it is found at Ali Abad 0.03mg/l, at Sunn 0.037 mg/l, at Shwan 0.037 mg/l, at Bubak 0.079 mg/l, at Bhan Saeedabad II 0.095 mg/l. in Dadu district areas: at Boriri 0.093 mg/l, at Dadu east 0.368 mg/l, at Dadu City center 0.383 mg/l, at Johi 0.371 mg/l, at Kakar 0.383 mg/l, at K.N shah 0.127 mg/l, at Mehar 0.144 mg/l.

In Mirpurkhas district: it is found at Naukot 0.495 mg/l, at Mirpurkhas North 0.596 mg/l, Sultanabad 0.324 mg/l. In Umarkot district: Umarkot city 0.496 mg/l, Thar Nabisar 0.578 mg/l, Samaro 0.586 mg/l. In Sanghar district: Tando Adam 0.529 mg/l, Khadro 0.619 mg/l, at Sanghar I 0.615 mg/l, at Shahpur Chakar 0.633 mg/l. in Nawabshah district: at Nawabshah city-I 0.515 mg/l, at New Saeedabad 0.541 mg/l, at Sakarand 0.563 mg/l, at Qazi Ahmed 0.301 mg/l is above the permissible limits of WHO (2004). However, the Cd concentration is found within the allowable limits at Mirpur Bathoro -0.392 mg/l (Thatta district), Tharehi -0.279 mg/l (Khairpur district) Vilage Ghindin -0.294 mg/l. The obtained data is presented graphicall (Table.3; Fig.8). The aerial distribution of Cadmium is shown through contour map and relief map in Figure 9 & 10. Lead (Pb): Lead is used in lead-acid batteries and alloys. The organolead compounds tetraethyl and tetramethyl lead have also been used as anti knock and lubricating agents in petrol. This use is now in a decline and the exposure from the air is declining but source from drinking water constitutes the major proportion. Lead is a general toxicant and accumulates in the skeleton. It is toxic to both central and peripheral nervous systems (Go´mara et al., 2007). Most of the lead in drinking water arises from the plumbing systems in the buildings. The measures to control the corrosion may reduce the amount of lead in drinking water. Allowable limit of Pb concentration in water by WHO (1975) is 0.01mg/l - 0.05 mg/l. Lead concentration in groundwater is found high in at Nousharo Feroz II 0.087 mg/l, Badin I 0.076 mg/l, Lakho pir 0.092 mg/l, Mithoro Chachar (Meghwar para) 0.068 mg/l, Mithoro Chachar (Bhel para) 0.078 mg/l, Nagarparkar 0.08 mg/l, Nagarparkar 0.062 mg/l, Bhalwa 0.071 mg/l, Mithi 0.065 mg/l, Tando Allahyar 0.074 mg/l, Umarkot, 0.084 mg/l, Sakarand 0.07 mg/l, Samaro 0.064 mg/l, Mirpur Khas North 0.069 mg/l (Table. 3), this concentration of Pb can be attributed to the Lithology of land and percolation of agricultural and municipal waste. However, Pb concentration at Ali Abad, Sunn, Shwan, Bubak, Bhan Saeedabad II, Boriri, Naseerabad-I, K.N shah, Mehar, Larkana city west, Larkana city center , Larkana city north, Fateh Pur, Bungul Dero, Garhi Yaseen, Shikarpur, Khanpur, Ghospur, Kandh kot, Kashmore, Guddu, Maripur, Obauro, Daharki, Pano Aqil, Ghotki, Sukkur I, Rohri I, Sukkur II, Sukkur III, Sukkur IV, Sukkur VI, Babar loi,Tharehi, Ramzanpur, Abad, Jacobabad city east, Jacobabad city center, Khairpur Mirs II, Kot Deji, Kumb, Ranipur, Bhehlani, Dadu east, Dadu City center, Johi, Kakar, Matli, Talhar, Tando Mohmmad Khan II, Mirpur Bathoro, Tari III, Kadhan, Diplo, Tandojam, Matiari, Tando Adam, Nawabshah I, New Saeedabad, Thar Nabisar, Khadro, Halla, Sanghar I, Shahpu Chakar, Qazi Ahmed, Sultanabad and at Village Ghindinm is found within the permissible limits of WHO. The obtained data is presented graphicall (Table.1; Fig. 12). The aerial distribution of Lead is shown through contour map and relief map in Figure.13 & 14. Zinc (Zn): Zinc, like magnesium and selenium, is also an essential trace element. It is found in all foods and potable water. The levels of zinc in surface and ground water normally do not exceed 0.01 mg/l and 0.05mg/l respectively (WHO, 1996). Concentration in tap water may increase due to dissolution from the pipes (WHO, 2004). For any water to qualify as potable, these constituents must be below the specified limits. According to WHO (1975), the permissible limit of zinc in all the water samples is 5 mg/l or 500 µg/l. Zinc concentration in the water samples collected from different district in Sindh province is given in Table 3 and graphically presented in Figure 15 and the data is also plotted on contour and relief map(Fig.16 & 17). The concentration of Znic in all the groundwater samples is found within the permissible limit (Table.1).However, the higher concentration is noticed in the sample collected from hand pump at Sakarand it contents 10.95 mg/l ZnHigher than that of recommended by WHO for Normal drinking water.

Disscussion and Conclusion Lower Indus plain formed by the alluvial deposits of the I n d u s Riv er a s w ell as of H a kra Riv er (Lambrick, 1964; Pithawala, 1976; Kalyanaraman, 2003; Panhawar, 2002). The entire surface is furrowed and cross-furrowed by beds of older river channels, which have left their fertile meanders in many pieces. Hydrologically the entire province is irrigated by water originating from Guddu, Sukkur and Kotri barrages; however, the groundwater is 28% fresh. According to pipper (1944) water classification scheme the groundwaters of Sindh provence are generally prevailing (hydrogen) Carbonatic type and prevailing sulfatic There is a greater variation in the pH of the waters of all the area. It is Fig 9. Map shows the distribution of ground water and its ranging from neutral (pH = 7.2) to slightly quality in Sindh Province. (after Panwhar, 1964). alkaline (pH = 8.5). however it is found within the pemissible limits of WHO (2004). The total dissolved solids (TDS) and electrical conductance (EC) in the ground waters of the study area are genrally within the permissible limits of US-EPA (1978) and WHO (2004) and considered as fresh water in Dadu, Jamshoro, Larkana, Nawabshah, Sukkur, Ghotki, Kashmore, Jacobabad, Thatta, Badin Mirpur Khas, sanghar, Umarkot and Hyderabad district. However, all the sample collected from Tharparkar district showed very high concentration of TDS and EC in groundwater (Table.1). The heavy and trace elements (i.e., As, Cd) in the subsurface waters of Sindh area are generally above the permissible limits of US-EPA (1978); WHO (2004). The Arsenic contents are found higher at Maripur Mathelo, Rohri, Sukkur VI, and Dadu east, Tando Mohmmad Khan II, Mirpur Bathoro, Diplo, Nagarparkar, Bhalwa, Tandojam, Nawabshah I, Sanghar I. The Lead concentration in groundwater is found high at Nousharo Feroz II 0.087 mg/l, Badin I 0.076 mg/l, Lakho pir 0.092 mg/l, Mithoro Chachar (Meghwar para) 0.068 mg/l, Mithoro Chachar (Bhel para) 0.078 mg/l, Nagarparkar 0.08 mg/l, Nagarparkar 0.062 mg/l, Bhalwa 0.071 mg/l, Mithi 0.065 mg/l, Tando Allahyar 0.074 mg/l, Umarkot, 0.084 mg/l, Sakarand 0.07 mg/l, Samaro 0.064 mg/l, Mirpur Khas North 0.069 mg/l. This may be due to Lithology, agricultural waste, municipal waste water percolation. The lack of proper outlet to rain water to its natural courses can not be ignored, because due to this water table raises which it brings soluble minerals with it, which never goes back after the water table fall down. However, Cadmium is within the permissible limit in groundwater. The concentration of Zinc is also found within the allowable limits of WHO (2004) except the sample collected from Sakrand which showed higher contents of Zn. During this study, it has been noticed that the LBOD, KPOD and DPOD and the sea intrusion are the main cause of disturbing ground water in lower Sindh. Specific measures should be taken before it turns into any kind of disaster. The following necessary remedial measures are suggested to minimize the affects of natural and anthropogenic sources of pollution in the area: • To save groundwater in the area, the alternative/ safe ways shall be adopted to dispose the wastewaters.

21

• •

• • • • •

During monsoon proper arrangements shall be taken to dispose off water rather than making it stagnant. Operation and maintenance of irrigation canals is essential. Efforts should be made to carry out for their proper operation and maintenance because Sindh has mainly arid climate and the ultimate source for the recharge of aquifer is river water, otherwise remaining 28% fresh groundwater will turn into brackish. The treated effluents shall be discharged into surface water system to abide by minimum dilution factor. The industrial wastewater and sugar mill waste effluents are mainly disposed in surface waters as untreated (i.e., in Badin). The owners of the industries should be penalized for discharging, untreated effluents in the drainage system. In order minimize the effects of pollution on the in habitants; the people should be educated about hazards of the polluted water and its impacts on the environment. In this regard, workshops for the awareness of local communities shall be convened. NGO’s can also play their role in the advocacy and awareness among the people on water quality and its health issues. It is strongly suggested that Sindh government should routinely monitor the quality groundwater.
