Omdurman is situated at the junction of the Blue and the White Nile. Results Six samples were taken from the groundwater in north of Omdurman mainly ( Algezira Islanj and Huraizab areas). The samples were subjected to physical and chemical examinations. The main investigated parameters were, total dissolved solid, pH, turbidity, electrical conductivity, alkalinity, total hardness and heavy metals. The turbidity level from Algezira Islanj was in range of (7.10 - 21.40) which was higher than the acceptable level for drinking water stated by World Health Organization (WHO), and Sudanese Standards and Metrology Organization (SSMO) specifications. The levels of alkalinity, total dissolved solids and hardness in all samples were in the range. Ammonia content from Huraizab samples were higher than the maximum value (1.5mg/L). The study showed that the concentrations of iron, arsenic, nickel, and lead for groundwater in the study area were higher than the permitted limits suggested by World Health Organization and Sudanese Standards and Metrology Organization specifications. Analytical Chemistry Physical properties chemical constituents ground water drinking water Omdurman Figures Figure 1 Introduction Water is vital natural resources for living organisms and human being. It effects the life and economy of surrounding people of certain area [1]. The world health organization [2] mentioned that a number of organic and inorganic chemicals have been reported in drinking water, with ow or high concentrations, the chemicals indicated include the potential hazards to mankind. One billion of people in the world do not has access to safe water and 2.5 billion lack access to adequate sanitation services [3]. Ground water comes from small percentage of precipitation that falls, in filtrates, traveling downward, and fills the available pore spaces within rock sand, gravel, and clay. This forms a large subsurface storage area of water which interacts with various rocks, minerals, microorganisms, most chemicals contact the ground water can be positive or negative to water quality [4]. Contaminants such as, heavy metals, nitrates, salt, bacteria and viruses reaches water supplies due to inadequate treatment and disposal of waste (human and livestock), industrial discharges, and over-use of limited water resources [5]. High levels of metals and other chemicals that can harm people health. Chemicals containing arsenic, barium, chromium mercury, nickel, , lead , selenium , copper and zinc, effect natively on human health (Kidney, liver and brain) [6]. Sudan is one of the largest country in Africa and lies mostly in the arid region where water limited resource, however it is considered to be rich in water resources. The available water resources are Nile system, rain water and ground water [7]. The objective of this study was to investigate the physical and chemical parameters of six water samples collected from ground water from Algezira Islanj and Huraizab water stations resources and compare the results values with the Global standards (world health organization) and local standards (Sudanese Standards and Metrology Organization). Main Text Al gezira Islanj and Huraizab are villages are located about 10 km northeast of Omdurman city and are a part of Karary locality that lies between longitudes 15 -11.5 /16- 39.5 east and latitudes in 32-36.5 / 31 -37 north. The population is about 12 thousand people for both regions. The distance from Algezira Islanj to Huraizab is about 5.4 km. Algezira Islanj contains 4 main wells, while Al Huraizab contains two main wells for drinking water supply as showed in Figure 1 Ground water samples were taken from Algezira Islanj in from four stations (A, B, C and D) and Huraizab two stations (E and F), the depth between 13-20 m. Water samples were taken after allowing the water pumps, from wells, to run for short time to remove the first water flushes, one and a half liters were collected in clean plastic bottles and half liter were collected in clean glass bottles. The bottles were rinsed twice with water before collection, and the samples are acidified with 1.5 ml of nitric acid per liter, closed and immediately transported to laboratory for physical and chemical analysis. These samples are stored at 4°C before analysis. The samples were collected during the month of July 2020. The pH, Electrical conductivity, and total dissolved solid were measured in the field. The pH was measured using (portable-jenway pH meter). Electrical conductivity and total dissolved solid were measured using HQ30d-HACH conductivity meter. Turbidity was measured using TL2360-HACH Turbidity meter. Total hardness of water expressed as calcium carbonate, measured by Ethylene diamine tetra acetic acid EDTA titrimetric method. Alkalinity, calcium content and chloride were determined by titration method. Magnesium was determined by subtracting the calcium hardness from total hardness as mg / L. Sodium and potassium were determined by using Flame photometric method (Flame photometer). Nitrate, ammonia, Phosphate and Silica were determined by using spectrophotometer DR HACH (5000). Iron, Zinc, Lead, Arsenic and Nickel were determined by using inductively coupled plasma mass spectrometry (ICP-MS). Table 1 showed pH values, electrical conductivity (EC), total dissolved solid (TDS) and turbidity levels. Table 1. pH, electrical conductivity (EC), total dissolved solid (TDS) and turbidity levels for six water samples collected from Al gezira Islanj and Huraizab areas, Omdurman Sudan. Parameter A B C D E F pH 7.20 7.10 7.00 7.10 7.10 7.10 EC 813 402 853 451 868 595 TDS 534 226 503 247 508 319 Turbidity 13.40 7.10 21.40 9.20 1.84 1.02 The levels of alkalinity (Table 1 supplementary materials), total dissolved solids and hardness in all samples were in the range. All the pH values, electrical conductivity (EC), total dissolved solid (TDS) fall within the acceptable level of WHO (1993) and SSMO (2002) standards (6.5-8.5). The readings of turbidity in ground water from Algezira Islanj stations (A, B, C and D) fall above the maximum level of WHO (1993) and SSMO (2002) standards (≥ 5 NTU), while the readings of turbidity in ground water from Huraizab water stations (E and F) fall in the range. The highest value of turbidity (21.40NTU) was found in (A) sample, while the lowest value (1.02NTU) was found in (F) sample. High turbidity of water is often associated with high levels of disease causing organisms such as viruses, parasites and bacteria responsible for symptoms such as nausea, cramps and diarrhea [8]. The total hardness and alkalinity readings fall below the maximum level of WHO (1993) and SSMO (2002) standards for maximum level (500mg/L) The highest values of concentrations of chloride, ammonia, phosphate, silica and nitrate in (mg/L) were found in station (E), (F), (D), (F), and (A) respectively (Figure 1 supplementary materials). Except ammonia all these readings fall below the maximum level of WHO (1993) and SSMO (2002) standards for maximum level (500mg/L). Ammonia content from Huraizab samples were higher than the maximum value (1.5mg/L). Presence of ammonia in ground water may be attributed to natural minerals or through pollution by application of fertilizer, sewage and industrial waste [9]. Table 2. Iron, zinc, lead, arsenic and nickel values present in six water samples collected from Al gezira Islanj and Huraizab areas, Omdurman Sudan Parameter A B C D E F Iron 0.837 1.352 0.753 0.947 0.656 0.616 Zinc 1.670 2.340 3.020 0.120 1.350 1.270 Lead 0.278 0.270 0.275 0.274 0.279 0.271 Arsenic 0.286 0.260 0.278 0.293 0.277 0.301 Nickel 0.117 0.122 0.123 0.119 0.125 0.116 From (Table 2) the highest values for iron, zinc, lead, arsenic, and nickel were found in station (B), (C), (E), (F) and(C) respectively. Except zinc, all these readings of trace elements fall above the maximum acceptable level, of WHO (1993) and SSMO (2002) standards. Lead concentration scale in all studied samples are exceeding compared WHO Standards, all water samples were shown Lead contain in levels above the maximum contaminant Level (0.01mg/L) with the maximum concentration detected being (0.279 mg/L), these results are of concern as lead has been recognized for centuries as a cumulative general metabolic poison [10]. High values may be due to the effects of discharge of industrial effluents compounds including heavy metals [11]. As well as with reduced intelligence quotient in children and with attention disorders Lead enters into environment from industry, mining, plumbing, gasoline, coal, and as a water additive [12]. The elevated levels of arsenic in the study area may be due to its evaporative environment since the climate of this region is arid which can lead to more loss of water by evaporation than its gain by rainfall. Arsenic contamination is also strongly associated with high concentrations of iron, phosphate, and ammonium ions, and anthropogenic activities such as excessive groundwater withdrawal for agricultural irrigation [13]. The major source of metal pollution in water is use of pesticides in the form of calcium arsenate, lead arsenate, sodium arsenate and arsenic acid (Figure 2 supplementary materials) [14]. Iron is the second most abundant metal in the earth’s crust. i t may be released to water from natural deposits, industrial wastes, refining of Iron ores, and corrosion of Iron containing metals. The maximum allowable limit for Iron as per WHO guidelines is (0.3 -0.947 mg/L), Iron concentration levels in all studied samples are exceeding then compared WHO Standards. Nickel concentrations in groundwater depend on the soil use, pH, and depth of sampling, the primary source of nickel in drinking-water is leaching from metals in contact with drinking-water, such as pipes and fittings. However, nickel may also be present in some groundwater as a consequence of dissolution from nickel ore-bearing rocks. Acid rain increases the mobility of nickel in the soil and thus might increase nickel concentrations in groundwater [15]. Limitations This work concluded that groundwater in the study area is chemically unsuitable for drinking use. The analysis of water samples revealed that the groundwater samples from almost all the locations is highly contaminated with some heavy metals, turbidity and ammonia. It is recommended to carry out a continuous water quality monitoring program and development of effective management practices for utilization of water resources. However due to lack of some lab facilities and more sophisticated and advanced equipment, as well as lack of funding.

Except zinc, all these readings of trace elements fall above the maximum acceptable level, of WHO (1993) and SSMO (2002) standards. Lead concentration scale in all studied samples are exceeding compared WHO Standards, all water samples were shown Lead contain in levels above the maximum contaminant Level (0.01mg/L) with the maximum concentration detected being (0.279 mg/L), these results are of concern as lead has been recognized for centuries as a cumulative general metabolic poison [10]. High values may be due to the effects of discharge of industrial effluents compounds including heavy metals [11]. \u0026nbsp;As well as with reduced intelligence quotient in children and with attention disorders Lead enters into environment from industry, mining, plumbing, gasoline, coal, and as a water additive [12]. The elevated levels of arsenic in the study area may be due to its evaporative environment since the climate of this region is arid which can lead to more loss of water by evaporation than its gain by rainfall. Arsenic contamination is also strongly associated with high concentrations of iron, phosphate, and ammonium ions, and anthropogenic activities such as excessive groundwater withdrawal for agricultural irrigation [13]. The major source of metal pollution in water is use of pesticides in the form of calcium arsenate, lead arsenate, sodium arsenate and arsenic acid (Figure 2 supplementary materials) [14]. Iron is the second most abundant metal in the earth\u0026rsquo;s crust.\u003cstrong\u003e i\u003c/strong\u003et may be released to water from natural deposits, industrial wastes, refining of Iron ores, and corrosion of Iron containing metals. The maximum allowable limit for Iron as per WHO guidelines is (0.3 -0.947 mg/L), Iron concentration levels in all studied samples are exceeding then compared WHO Standards. Nickel concentrations in groundwater depend on the soil use, pH, and depth of sampling, the primary source of nickel in drinking-water is leaching from metals in contact with drinking-water, such as pipes and fittings. However, nickel may also be present in some groundwater as a consequence of dissolution from nickel ore-bearing rocks. Acid rain increases the mobility of nickel in the soil and thus might increase nickel concentrations in groundwater [15].\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLimitations\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThis work concluded that groundwater in the study area is chemically unsuitable for drinking use.
