Abstract
Water is essential for survival of all living organism present on earth. There is no life without water. Water may be polluted due to anthropological activities, industrial discharge and sewages which affect the physical and chemical properties of water. The safe water is essential for healthy living. The present study area was Gilgit Baltistan. Water samples were collected from the springs, lakes, rivers, tap water and underground water and analyzed for physio chemical parameters. Six different physio chemical parameters were analyzed by using different laboratory methods and procedure. In the present study the value of pH ranged from 5.93-8.09, electrical conductivity 186μS-1444.3μS, total alkalinity 0-1638ppm, Calcium 20-174.6ppm, total dissolved oxygen 7-13.2, total dissolved solid 51.1-461.6, turbidity 0.18-19.86, Magnesium 6.4- 64.4ppm, and Chloride 68.25-191.27. The results obtained were compared with WHO standards for drinking. Some parameters fall within WHO standard while some parameters were exceeding or below permissible limits.
Introduction
General Introduction
Water is the most important gift from nature to living organism. It is necessary for the growth and maintenance of human body and many biological activities. It plays an important role for the survival of all living organism. Because of solid suspended particles and dissolve impurities nature water is not pure for human. Due to presence of heavy metals in natural water, it is not safety for human life. Metal contamination is due to atmospheric deposition, weathering or release of agricultural residential or manufacturing runoff. 66% of drinking water in Pakistan is obtained through pipe and hand pumps. 30% of waterborne diseases and 40% of people dies due to unavailability of clean and safe water [1,2].
The main constituent of human body is water. The water produce by metabolism or ingestion of food is not enough to fulfill our body needs. So we have to pay attention of our drinking water. Water is important for life and is important constituent of cell, tissue and organs [3]. The human body weightconstitutes75%water and most vegetables contain 80% water [4]. Water has various roles in the human body. It acts as a building material; as a solvent, reaction medium, as a carrier for nutrients and waste products; in thermoregulation; and as a lubricant and shock absorber [5].
Because of harmful physical, chemical and biological agents many water resources are unhealthy. At least 2.5 billion peoples in developing countries have poor hygienic water system and over 780 million people have no right to use safe drinking water. As a result across the world about 2.3 billion people suffering from water related disease. [6]. Due to presence of high concentration of chemicals or its poor supply in water may cause different diseases like goiter and cancer [7]. Due to lack of cleanliness, better sewage treatment and use of extremely dirty water many gastrointestinal illnesses are in common [8]. Dental flurosis is cause by low or high level of fluoride ions concentration in water. Goiter is mainly due to low concentration of iodine in human. A potential high risk group has been considered in infant to the toxic effects of sodium from drinking water [9]. There would be 200milion fewer cases of diarrhea and 2.1 million fewer deaths caused by diarrheal illness each year if everyone had pure drinking water and satisfactory sanitation service [10]. Different acute and chronic health issues may cause because of toxic inorganic chemicals in water. Vomiting, nausea, dizziness, lungs irritation, skin rash and sometime death may occur due to acute effect. Cancer, birth defect, organ damage and some disorders of nervous system and immune system are included in chronic effect.
In northern area of Pakistan glacier and snow deposits are the main source of water for domestic purpose. The main contaminated source of water is spring water and showed the positivity of different bacteria like E.coli, total coliform bacteria and salmonella, human and animal fecal waste easily contaminate the exposed water [11]. Natural water is a universal and impressive symbol of life. Every person requires around 2 liters of clean drinking water and this amount reaches approximately 12 million m3 /day for the world population. According to WHO in total, there is 1400 million billion liters of water, but most of this water is not used for potable purpose, because 97% is sea water and only 3% is fresh water, out of which 2% is routed in the polar icecaps and glaciers, only 1% water is accessible for drinking purpose, whereas major water goes for irrigation than to drinking and all other use. The feasible water is of very poor quality. At the present situation, only 80% of the population in case of urban areas and only 11% in case of rural areas have access to the piped water [12].
All living organisms, most ecological systems, human health, food production and economic development depend on water [13]. Rivers, lakes, glaciers, rain water, ground water are main source of water. Besides the need of water is not only use for drinking purpose but also play an important role in different area of economy such as agriculture, livestock production, forestry, industrial activities, hydropower generation, fisheries and other creative activities. Due to some important factors like increasing population, industrialization, urbanization etc, the feasibility and quality of water either surface or ground, have been disintegrate. By using physical, chemical and biological parameters water quality of any specific area or specific source can be assessed. If the values of these parameters become more than defined limits, is harmful for human health [14].
Good quality and adequate water supply services are basic requirement for community health and well-being. Due to harmful physical, chemical and biological agents many water resources in developing countries are unhealthy. Due to presence of microorganisms in drinking water, usually has a physically great influence on the public health. So drinking water play important role in the spread of disease. Unfortunately, many people in the world are despoiling of this basic need [15]. Many of the freshwater sources are contaminated by use of pesticides in agricultural fields and other anthropogenic activities that completely change the physical, chemical, and biological processes related to water resources [16].
Introduction to Study Area
Northern area of Pakistan now called Gilgit Baltistan falls at junction of three mountain ranges namely Karakoram, Himalaya and Hindukush [17]. Geographically Gilgit Baltistan is mountainous, with zero temperature in winter, while in summer it may go beyond from 35 C0 [18].
Gilgit Baltistan is located at the extreme north of Pakistan. It consist of 10 districts namely Gilgit, Skardu, Diamer, GhizirShiger, Hunza, Nager, Kharmang, Ghanche, And Astore. It lies between 350- 70 North, and 720-750 East. it is surrounded by chitral in West, Kalan, Kohistan and Kaghan valley in the South, and Ladakh and Kashmir in the South. Its area is 7294km² along with a population of about 1.5 million bordering Afghanistan, China, India and Iran [19].
The study area includes different regions of Gilgit Baltistan including: Skardu, Shiger, Gilgit, Nager, Kharmang, and Khaplu.
Physio-Chemical Parameters of Water
pH: The hydrogen ion activity is known as pH and is a measure of acidity and alkalinity of sample [20]. pH is most important in determining the acidic nature of water [21]. According to designated limits set by WHO pH values ranged between 6.5-8.5 [11]. Due to high decomposition activities in summer pH value become high [22]. Due to aggregated organic matters and decomposition of vegetation which release CO2 which basically reduces the pH [23]. A pH meter is an instrument used to measure acidity or alkalinity of a solution. pH meters consist of a glass electrode made of a specialty glass membrane that is sealed at the end forming a bulb. Inside the glass is an internal standard acidity solution, usually 0.1 M HCl, along with an internal reference electrode, (typically an Ag/ AgCl wire electrode). This solution is called the reference solution of known pH, 7.A second electrode REext is placed in an external tube immersed in KCl. This external tube forms a concentric enclosure around the first enclosed glass tube containing the 0.1 M HCl (the internal tube).The external tube is made of pH sensitive glass and is in contact with the test solution through an opening called a porous diaphragm. The inclusion of a reference electrode encased by the internal tube is necessary as its pH is known and can be compared to a test solution so that its pH value can be determined. This set-up is called a combination pH electrode.
Electrical conductivity: Determination of concentration of electrolytes in water is known as electrical conductivity [24]. Or Electrical Conductivity (EC) is the calculation of capacity of water to conduct electric current through it [25]. During the summer season the value of conductivity was recorded as high while it were low in monsoon [26]. Conductivity of water depends upon the concentration of ions and dissolves solid particles. Because of evaporation in summer season the concentration of salt increase which results in variation in conductivity [27]. The addition of rain water in monsoon season dilutes the water as a result electrical conductance decrease [28]. The estimated values of EC prescribed by WHO ranged between 1400 μS [2].
An Electrical Conductivity meter (EC meter) measures the electrical conductivity in a solution. An alternating voltage is applied across two electrodes which are immersed in the same solution. This applied voltage is use to flow a current. The magnitude of current depends upon the electrolytic conductivity of the sample solution.
Total hardness: Calcium and magnesium are the main source of water hardness, which are present in many mineral like limestone consisting chalk (CaCO3), some industrial products and common ingredients of food. A secondary donation to the total hardness of water is made by polyvalent ions like zinc, manganese, aluminum, strontium, barium, and iron [29] TH determine capability of water for domestic, industrial and drinking purposes [30]. Magnesium is one of the major ingredients of the hardness of water [31]. The reasonable amount of magnesium changes the quality of water [32]. The value of hardness of water becomes high due to evaporation during summer and addition of calcium and magnesium salts by mean of plants and living organism [33]. High values of hardness are probably due to regular addition of large quantities of garbage and detergent into lakes from the close residential sectors [34]. According to WHO standards water is soft if its hardness value ranges between 0-50, it is moderately hard when the value is between 50- 150 and water is said to be hard if hardness value rises from 150-300 [35].
Total alkalinity: The ionic concentration, which can neutralize the hydrogen ion, is known as total alkalinity of water or the capacity of water to neutralize a strong acid is called alkalinity. Alkalinity of water is due to presence of bicarbonates, carbonate and hydroxide compounds of calcium, sodium and potassium. [36]. Or the concentration of titratable bases in water is known as total alkalinity. A hydrogen ion (H+) will neutralize when base will react, for example, in the reaction:
H+ + OH- = H2O,
Hydroxyl ion is the base.
Carbonate (CO3 2- + H+ = HCO3-)
Bicarbonate (HCO3- + H+ = H2O +CO2)
Ammonia (NH3 + H+ = NH4)
The word “total” is added to alkalinity because of presence of different ions. Total alkalinity may sometimes be reported separately, for example, hydroxide alkalinity. In most natural water alkalinity is mainly due to HCO3, CO3 2, and OH [37]. The recommended value of total alkalinity is 500 mg/L [38]. Water having alkalinity less than 100mg/L is best for domestic use [39].
Dissolved oxygen: The majority of animals living in water required dissolve oxygen (DO) for the process of respiration.[18]. During the period of active photosynthesis DO is more in water [40]. Low value of DO in water is due to high temperature,increased microbial activities, addition of garbage and other waste product [41,42].
Chloride: One of the major inorganic anion in water is chlorine. The salty taste in drinking water is produced by the Chloride concentrations [43]. The high concentration of chlorides in water is due to throwing of garbage and industrial waste [44]. Human urine and feces are also source of chlorine in water. High rate of evaporation in summer and organic waste product of animal may increases the concentration of chloride in water [45].
Total dissolved solid: Water has the ability to dissolve a wide variety of organic and inorganic minerals and salts. WHO guidelines limit for TDS is 1000ppm [15]. The main components are usually chlorine, calcium, magnesium, sodium, potassium cation, potassium carbonates, hydrogen carbonate, chloride, sulphate and nitrate anion. Water containing TDS level less than 600ppm is safe while TDS level greater than 1000 ppm is not acceptable for drinking purpose. High level of TDS cause bitter taste to drinking water. It also affects a person who are suffering from kidney and heart problem [2]. Eutrophication of aquatic ecosystem may cause by high concentration of TDS [46].
TDS meter indicates the presence of total dissolved solid. All elements dissolved in water have some electrical charge. Therefore, it is possible to estimate the quantity of TDS by measuring the electrical conductivity of water by passing current through it
Turbidity: Turbidity of water shows the optical property in which the light is scattered by the particles present in water [47]. Turbidity in water is cause by clay, slit, phytoplankton’s, organic matter and other microscopic organism [15]. Turbidity also shows the presence of disease-causing organisms. These organisms include bacteria’s, viruses and parasites that can cause cramp, nausea and diarrhea. According to WHO guideline limit the turbidity of drinking water should be less than 5NTU [18].
Turbidimeter is an instrument use to measure the relative clarity of a fluid by measuring the amount of light scattering by particles suspended in a fluid sample

Conclusion
Physiochemical analysis of water is important to indicate their quality profile for various water uses for example associated with domestic and agricultural uses. The present investigation of water quality assessment of fresh water in Gilgit Baltistan has led us to conclude that some parameters fall within WHO standard while some parameter were exceeding or below permissible limits. According to WHO the pH value for drinking water ranged from 6.5- 8.5. All the water samples have pH value range in WHO standard limit. EC of all water samples ranges prescribed by WHO standard except main hot spring Shiger and chumik Shiger Bisil they exceeding the limit. Total alkalinity of all water samples exceeding the standard limit except few that is tap water Skardu, Burganala Skardu, Hopper Nager, Manthokha Abshare and Kharmang. Amount of calcium and magnesium of all samples ranges within limit. tubidity of all samples range within standard limit except Kharmang river and Mashrabrum glacier which exceeding the limit. Amount of dissolved oxygen total dissolved solid and chlorine also ranges in WHO standard limit.
