In the present study, a successful attempt has been made to develop a simple method for the simultaneous determination of manganese (II) and iron (III) in an industrial effluent using differential pulse polarography (DPP) technique. Quantification of manganese (II) and iron (III) was done in Triethanolamine and KOH as a supporting electrolyte. The polarogram recorded for the industrial effluent in triethanolamine and KOH showed two peaks at -0.3V and -0.82V vs. saturated calomel electrode which were confirmed to be of manganese (II) and iron (III) respectively by the method of standard addition. The linear working range for manganese (II) and iron (III) both was 1.408 µg/mL to 4.977 µg/mL. The proposed method was found to be simple, precise, and accurate and can be successfully applied for the analysis and simultaneous determination of manganese (II) and iron (III) in industrial effluents.

Studies of Physico chemical parameters of groundwater quality based on Physico chemical parameters of Ajmer city in Rajasthan have been taken up to evaluate its suitability for domestics purpose. 21 ground water samples were collected from different places of Ajmer city in Rajasthan. The quality analysis has been made through the pH, EC, TDS, Dissolved Oxygen, BOD, COD, Total Hardness, Sodium, Potassium, Calcium, Magnesium, Chloride, Sulphate, Nitrate, Fluoride and Alkalinity. A systematic calculation of the correlation coffecient has also been carried out between different analysed parameters. Comparative studies of samples in different seasons were conducted and it was found that Electrical Conductivity and Total Dissoved Solids TDS were decreased. Alkalinity and Total Hardness were increased after the rainfall. Ajmer is one of the major and oldest cities in the Indian state of Rajasthan and the centre of the eponymous Ajmer District. It is located at the centre of Rajasthan, and is home to the Ajmer Sharif shrine. The city was established as Ajayameru translated as Invincible Hills by a Chahamana ruler, either Ajayaraja I or Ajayaraja II, and served as their capital until the 12th century CE. Ajmer is in the northwest of India and is surrounded by the Aravali Mountains. It is situated on the lower slopes of the Taragarh Hill of that range. To the northwest is the Nagapathar Range of the Aravali Mountain Ranges which protects it from desertification from the Thar Desert.

Hepatitis A virus and environmental quality indicators in aquatic ecosystems ...Agriculture Journal IJOEAR
Abstract - Research into the occurrence of microbiological contaminants, including hepatitis A virus (HAV), in river waters intended for oyster farming is of extreme importance for public health. This study aimed to detect the occurrence of HAV in the aquatic environment for ostreiculture in northeastern Pará, Brazil, and correlate with microbiological, physico-chemical and climatological variables. The HAV research was based on the method of water concentration by filtration membrane adsorption-elution and in the organic flocculation method with skim milk, followed by Nested-PCR. Quantification of coliforms, Enterococci and heterotrophic bacteria was performed. The physico-chemical variables were measured with multiparametric probe and spectrophotometry. Positive samples were purified and submitted to sequencing. From March 2017 to December 2018, 203 samples of river water were collected and analyzed in the municipalities of Augusto Corrêa, Curuçá, Salinópolis and São Caetano de Odivelas. In 10.8% of the analyzed samples the HAV RNA was detected, in all localities the HAV was classified in genotype IB. There was no significant difference between the concentration methods of the water samples. The only physicochemical variable that most influenced HAV detection was dissolved oxygen. Regarding the bacterial indicators, the highest statistical significance occurred with thermotolerant coliforms and Escherichia coli. The detection of HAV in the four municipalities studied shows that the virus is circulating in the aquatic environment and, therefore, in the community. In this context, more effective hygienic-sanitary measures are necessary in these communities dedicated to oyster farming.

Water samples were collected from different sources of Silchar Municipal area of Cachar district, Assam, India.
Physicochemical parameter such as PH
, EC, Hardness, Chloride, Fluorides, Iron, TDS of sixteen water samples
from different sampling sites of Silchar were determined. The experimental results were compared with
drinking water quality standards laid down by Indian Council of Medical Research (ICMR) and World Health
Organization (WHO) and it was found that only a few water samples are not suitable for drinking and other
domestic purposes due to high concentration of iron. Overall all the ground water is clear, odourless and soft.
Even few samples contain fluoride ion but the values are much below the permissible limits.
Environmental Indicators: Measuring Urban Development in Mountains of India. Presented by Kashinath Vajpai at the "Perth II: Global Change and the World's Mountains" conference in Perth, Scotland in September 2010.
The study was conducted to evaluate the groundwater
quality of Aligarh city, (India). Groundwater samples were
collected from 40 wells and analyzed for 20 water quality
parameters in post-monsoon seasons during the year 2013. High
coefficient of variance indicates variability of physico-chemical
parameters concentrations in ground water. The descriptive
statistical analysis was done beside Pearson correlation. From
correlation analysis it was observed that very strong correlations
exist between total hardness and Mg++ (0.99), TDS and total
hardness (0.88), TDS and Chloride (0.87). In 100% of the
samples recorded alkalinity and magnesium concentration were
found higher than maximum permissible limit prescribed by BIS.
Concentration of hardness, cadmium, pH, iron, lead, and total
dissolved solids were also found above the standard limits
prescribed by BIS. This reveals deterioration of water quality. It
is therefore, suggested to take up regular monitoring of
groundwater in areas of Aligarh city.

The Effluent Quality Discharged and Its Impacts on the Receiving Environment ...Agriculture Journal IJOEAR
The study evaluates the performance of Kacyiru Sewage Treatment Plant and its effluent impacts on the receiving wetland. Influent and effluent wastewaters as well as receiving wetland water qualities were measured from April to September 2019, at Kacyiru estate. The average removal efficiency (%) of the parameters such as TN, TP, COD, BOD 5 were recorded as 46.57; 61.49; 50.51; 66.79 respectively. The parameters such as pH, TDS, temperature value, were recorded within the prescribed limit of Rwanda standards for domestic wastewater discharge. The other parameters such as NTU, TN, TP, TSS, BOD 5 and Fecal coliforms were not complying with National standards requirements for domestic wastewater discharge. The finding showed that the excess nutrient observed may present potential sources of pollution in wetland and decrease the oxygen levels which affect the water living organisms. The discharged effluents contain microbes which can negatively devastate the receiving environment, thus the effect of discharged wastewater on environment is significant.
The challenges of river water quality management are so enormous, due to the unpredictive modes of contamination. Monitoring different sources of pollutant load contribution to the river basin is also quite tasking, resulting to laborious and expensive process which sometimes lead to analytical errors. This study deals with the assessment of the physico– chemicaland bacteriological parameters of water samples from River Amba during the period of August 2017 to January 2018 and developing regression models. Water quality Parameters such as Temperature, Turbidity (NTU), Suspended solids (mg/l), Colour, Total solids, Total dissolved solids, Electrical conductivity (μs/cm), pH, Hardness, Chemical Oxygen Demand, Dissolved Oxygen (DO), and Total Coliform were obtained and compared with water quality standards. The results of the water quality analysis of the study in comparison with drinking water quality standard issued byWorld Health Organization(WHO) and National Agency for Food and Drug Administration Control (NAFDAC) revealed that most of the water quality parameters were not adequate to pronounce the water potable. Hence adequate water treatment processes should be employed to make the water fit for consumption and other domestic uses. Statistical analysis was done, in which the systematic correlation and regressionanalysis showed a significant linear relationship between different pairs of water quality parameters. The highest correlation coefficient between different pairs of parameters obtained is (r = 0.999), resulting from the correlation between TS and SS. Multiple regression analysis was also carried out and regression equations were developed. It was observed that the parameters studied had a positive correlation with each other.

:In the present study, Paliurus spina-christi Mill. Frutis and Seeds (PSCFS) was used as an adsorbent for the investigation of the adsorption kinetics and thermodynamic parameters of methyleneblue (MB) from aqueous solution at various temperatures and concentrations. Six kinetic models, the pseudo-first-order, pseudo-second-order, intra-particle diffusion, Elovich, Bangham and Avrami equations were used to predict the adsorption rate constants. It was found that the kinetics of the adsorption of MB onto PSCFS at different operating conditions was the best described by the pseudo-second-order model. The rate parameters of the other kinetic models for adsorption were also evaluated and compared to identify the adsorption mechanisms. The equilibrium constants were used to calculate thermodynamic parameters, such as the change of free energy, enthalpy and entropy. Thermodynamic analysis showed that adsorption was favourable and spontaneous, endothermic physical adsorption and increased disorder and randomness at the solid-solution interface of MB onto PSCFS

Synthesis and Characterization of Different Molecular Weights PolyacrylamideIOSRJAC
Polyacrylamides of varying molecular weights (very low, low, medium, high and very high) were synthesized using free radical polymerization and characterized by Infra Red (IR) spectroscopy, viscosity measurements, glass transition temperature (Tg) measurement and thermal gravimetric analysis (TGA). Thioglycolic acid and hydrogen peroxide were used as initiators to synthesis very low and low molecular weight polyacrylamides respectively. Molecular weights (medium, high and very high) polyacrylamides were synthesized using potassium persulfate and N,N,N',N'- tetramethylethylenediaminesystem as initiators. The synthesis of medium, high and very high molecular weight polyacrylamides were achieved by increasing the concentration of acrylamide monomer. Fourier Transform Infrared Spectroscopy (FTIR) of polyacrylamides showed strong absorption at wave number 1655 cm-1 due to the presence of primary amide band. The results also showed that the increase in the intrinsic viscosity and glass transition temperature were proportional to the increase in molecular weight of polyacrylamide. On the other hand it can be seen an increase in molecular weight caused a decrease of weight loss %.
Kinetic Modeling of Vitamin C (Ascorbic Acid) Degradation in Blanched Commonl...IOSRJAC
Vitamin C (ascorbic acid) is one of the most important and popular vitamins, and is contained in most fruits and vegetables; the problem with vitamin C is its easy degradation during processing. In this study, the degradation kinetics of vitamin C was determined in Lettuce and Cabbage, and the processing treatment considered was blanching at 700C of water differently for 5, 10, 15, 20,25,30,35 and 40 minutes. Samples were dried in mild temperature (15–200C) and ground to find dust and High Pressure liquid chromatographic (HPLC) was used for determination of the AA of vegetable salad samples which consisted of an isocratic elution procedure with UV-Visible detection at 245nm. The rate constants were calculated for both vegetable salad samples under the same processing method using the integrated law method; half-life was also calculated. Degradation of ascorbic acid in Lettuce and Cabbage under the same pretreatment procedure followed the firstorder kinetic model, as the coefficient of determination (R2 -value) were 0.8981 and 0.9785 respectively. The rate constant of ascorbic acid degradation for Lettuce and Cabbage under the same blanching conditions were 0.099 min-1 and 0.088 min-1 respectively. The half-life of Lettuce and Cabbage were 420.0892 and 472.6004 seconds respectively. The most appropriate vegetable salad under the blanching pretreatment procedure is the cabbage because its rate constant depicted from the model equations was lower, and the half life longer, hence, slower rate of degradation. The first order forecast (Ln(C)), was 0.657964 for Lettuce and 1.330017 for Cabbage, which further authenticate that blanched Lettuce degradation was higher than Cabbage under the same pretreatment conditions.

The efficiency of the husk, stalk, cob and seed chaff from maize biomass in the removal of Zn2+ ions from solution under different conditions was studied and compared. Fourier Transform Infrared spectra of the different biomass parts before and after adsorption of metal ions showed that the husk and cob had more available functional groups and as such active sites for the adsorption of Zn2+ ions than the seed chaff and stalk. Percentage removal of Zn2+ions from solution increased with increase in the studied pH range for all the parts. This value also increased with increase in biomass load for the husk and cob but showed an alternating increase and decrease in Zn2+ ions removal as biomass load increased when the seed chaff and stalk were studied. At optimum pH and biomass load for the studied parts the maize husk gave the best removal efficiency of 72.8 %, making it a promising green packing material for industrial scale water treatment application.

The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Abstract: The quality of drinking water in some of the northern suburb communities of Khartoum North, Sudan
was investigated with respect to electrical conductivity (EC), total dissolved salts (TDS), pH, major ions (Ca+2
,
Mg+2
, Na+
, K+
, SO4

, NO3
-
,HCO3
-
, Cl-
) and total iron, beside coliform bacteria (E.coli and streptococci) as an
indicators of fecal contamination. The results obtained revealed that 20% of the samples were above the
maximum limit of both 1.6dSm-1
and 1000mgl-1
set by SSMO and WHO for EC and TDS, respectively. About
25% of the samples exceeded the maximum limit of 200 mg/l set by SSMO and WHO for Na+
. Most of the major
ions and total iron were found within the recommended limits of the local, regional and international standards
of drinking water. Microbiological analyses indicated that 55% of the samples were contaminated with coliform
bacteria. It may be recommended that continuous assessment of drinking water quality, on routine basis, is
imperative and a better management and monitoring are warranted to reduce the deterioration of aquifer water
quality in the region.
Keywords: Water quality, contamination, major ions, coliform, standards.
I. Introduction
During the last decade, it has been observed that groundwater is vulnerable to pollution due to the
increasing urbanization and human activities. Consequently a number of cases related to water borne diseases
were detected which may be linked to deterioration of water quality. Therefore, basic monitoring on water
quality is deemed necessary to cope with the rising demand and hence the expected, pollution risk level of
groundwater (Abdel Magid, 2016). A good number of water analysis experiments were regularly conducted by
different groups of chemists and biologists in this regard (Abdel Magid et al.,1984; Abdel Magid, 1997;
Redhaiman and Abdel Magid, 2002, Shomo, 2007; Abdellah et al., 2013). Based on taste, Abdellah et al. (2013)
suggested the following classification for groundwater on the basis of TDS level: 1) < 200 mg TDS/l as
palatable water ; 2) 200 - 500 mg TDS/l as potable water ; 3) 500 - 750 mg TDS/l as none palatable water ; 4)
750 - 1000 mg TDS/l as salty taste water ; 5) 1000 – 1500 mg TDS/l as saline water ; and 6) > 1500 mg/l TDS
as brine water . However, water used for drinking purposes should be free of suspended impurities, dissolved
harmful salt and disease - causing microorganisms. The suitability of groundwater resources is determined by
both the quality of the water and by the available yield. The chemical quality of groundwater depends primarily
on the level of TDS (Abdellah et al., 2014). Equivocal and undocumented concern indicated that potential health
hazards may arise from drinking saline and bacteriologically contaminated water in the area of study since the
drinking water is still distributed by vendors on donkey mounted water distribution carts (Plate 1 and 2).
However, absence of current or previous aquifers study data for wells drilling, legislations and sanitary laws
may accentuate the problem. The main objectives of this study are to evaluate the physico - chemical and the
microbiological characteristics of well water samples collected from diverse drinking water sources in the study
area and to compare the results obtained with the local (national), regional and international standards and
guidelines.
II. Materials And Methods
Description of study area:
The area under study is located at the northern eastern part of Greater Khartoum State, Sudan. Wells
under investigation were drilled in Samrab, Dardog, and Hattab suburban communities. Khartoum city the
capital of Sudan is located in the central part of the country which is located between latitudes 15º26’ and
15º45’ N and longitudes 32º25’ and 32º40’ E, at an altitude of 405.6 m above sea level (Shakesby, 1991).
According to Perry (1991), the main climatic conditions of Greater Khartoum are conditioned by its location on

the southern fringes of the Sahara, the city experiences four climatic seasons, the winter season extends from
mid-November to March, with a minimum temperature ranging between 8ºC and 10ºC which falls to 5ºC during
night, and maximum temperatures varying from 23ºC to 25ºC, and a relative humidity which may sometime be
as low as 20 per cent, the hot, dry summer season is well in place by the end of March, the maximum
temperatures may exceed 45ºC by the end of May, the rainy season covers the period from July to September,
with August being the rainiest month. Generally, annual rainfall ranges between 110 and 200 mm. A short, hot
(about 40ºC) transitional season occurs between mid-September and the beginning of winter.
Collection of water samples:
For the physico - chemical tests twenty drinking water samples were collected in clean plastic bottles
after rinsing with the sampled tap (public stands water known locally as Sabeel drinking water) or well water at
the collection site. For the bacteriological tests the water samples were collected in sterile glass bottles and
immediately rushed to the laboratory in iced containers.
Laboratory work:
Laboratory analyses were mainly carried out at the Dept of Soil & Environment Sciences, Faculty agriculture,
University of Khartoum.
Chemical Examination:
The pH value was measured by pH-meter (Jenway. Model: 3510. England 2009). EC (dS/m at 25o
C)
was measured by EC-meter (Model: M35. Serial NO: 3405). Na+
and K+
were determined by flame photometer
(Model: PFP7, Jenway-England) according to the APHA (1985,1998). Ca+2
and Mg+2
were determined by
titration with Ethylene Di amine Tetra Acetic acid (EDTA) disodium salt (0.01N). Sulfate, nitrate, bicarbonate
and chloride were determined according to Richards (1954). Total dissolved salts were determined by
multiplying the EC value obtained by (640) according to Rhoades (1982).
Microbiological analyses:
The media and chemicals used in this study were purchased from Elrebooa CO. Ltd., Assouk-el-Arabi,
Khartoum, Sudan. These media and chemicals were used to detect and enumerate different types of
microorganisms according to Harrigan (1998) Before sterilization, glassware, to be used in the analysis, was
washed thoroughly with deionized water and left to dry and then sterilized in a hot oven at 160o
C for at least 3 h
(Harrigan and McCane, 1976). Instruments such as loops, needles, forceps, spoons and knives were sterilized by
flaming directly after dipping in spirit.. The total viable count of bacteria was carried out by using the pour plate
count method. For the determination of coliform bacteria in water samples, the multiple tube technique was used
according to Harrigan (1998). This method is known as the dilution method or Most Probable Number (MPN)
technique. The number of positive tubes was calculated from the MPN tables and the results were recorded.
Statistical analysis:
Statistical analysis of the data obtained were performed using calculator to estimate the mean and
standard deviation. The means obtained for the various parameters were evaluated according to the current
national (SSMO, 2002), regional (SASO, 1984) and international (USEPA, 1976 and WHO, 1993) drinking
water standards and guidelines.
III. Results And Discussion
Groundwater samples of Samrab Community:
The results obtained for the Samrab community well water samples analysis (Table 1) revealed
differences in the magnitudes of the various levels of the parameters studied: EC ranged from 0.28 to 0.64dSm-1
(TDS range =179.2 to 409.6 mgl-1
) with an average value of 0.45dSm-1
(TDS = 313.8mgl-1
. Comparison with the
recommended standards and guidelines for drinking water salinity revealed that all of the samples studied are
falling within the recommended limits of the national (local), regional and international standards . Likewise,,
none of the following parameters, as shown in table 1, is above the guideline limits set by the respective
standards : pH values ranged from 6.5 to 7.1 with an average value of 6. 8. Ca+2
concentrations ranged from
1.4 to 3.5mgl-1
with a mean value of 1.9mgl-1
, . Mg+2
concentrations ranged from 1.1 to 2.5mgl-1
with a mean
value of 1.6mgl-1
.Na+
concentrations ranged from 30 to141mgl-1
with a mean value of 77.3mgl-1
.K+
concentrations ranged from 2.05 to 4.22mgl-1
with a mean value of 3.34 mgl-1
. Each of SSMO, SASO, USEPA
and WHO standards has not set any guideline value or limit for K+
. Cl-
concentrations ranged from 0.3 to

Well water samples of Dardog Community:
The results obtained for the Dardog community well water samples analysis (Table 2) are more or less
similar in magnitude to those obtained for Samrab community(Table 1) i.e. comparison with the standards and
guidelines of drinking water revealed that all of the samples studied are falling within the limits recommended
by the national, regional and international standards.
Groundwater samples of Hattab Community:
The results of the analysis of the water samples from Hattab community with respect to pH, Ca+2
,
Mg+2
, K+
, Cl-
, SO4
-2
, NO3
-
and HCO3
-
are within the limits recommended by the respective standards (Table 3).
However, the EC ranged from 0.88 to 18.0dSm-1
(TDS range = 563 to 11520 mgl-1
) with a mean value of 5.2
dSm-1
( TDS = 3296 mgl-1
) by the respective standards . Comparison with the standards and guidelines for
salinity of drinking water revealed that 66.7% of the samples studied are falling above the standard limit of
1.6dSm-1
(TDS =1000 mgl-1
) set by SSMO, 50% of the samples are falling above the standard limit of 2.3dSm-1
(TDS =1500 mgl-1
) set by SASO while 100% of the samples are falling above the standard limit of 500mg l-1
set by USEPA guidelines and standards.
High salinity drinking water with TDS levels violating the maximum recommended levels (as that
found in some wells of Hattab Community) is considered unsuitable for drinking but could be used for irrigation
of crops with good salt tolerance (Al-Redhaiman and Abdel-Magid, 2002). Previous studies indicated that in
some of the villages located to the extreme northwestern boundary of the study area the TDS levels were found
to range between 1088 and 1952 mg/l (Abdel-Magid etal., 1984). Abdellah et al. (2013,2014) reported a TDS
level ranging between 97 and 2600 mg/l in the southern suburb of Omdurman City and between 128 and 1024 g
in some wells in Grand Khartoum City. Moreover, Abdellah et al. (2012a) reported that, in the Al-Butana
region, groundwater salinity tends to decrease by continuous discharge which replaced by fresh recharge from
the low salinity Blue Nile water. Conversely, Al-Redhaiman and Abd-Magid (2002) and Munday and Andrew
(2008) incriminated over exploitation and excessive water pumping among factors that may elevate salinity
level in groundwater. Increasing levels of TDS in some groundwater areas are usually caused by the intrusion of
high salinity water due to over-exploitation in aquifers adjacent to seawater or by the replacement of low salinity
water with high salinity water in temperate climates (Drisckol, 1986). Sodium concentration (Na+
) ranged from
160 to 922 mg/l with a mean value of 424 mg/l thus revealing that about 83..3% of the samples studied are
falling above the Standard limit of 200 mg/l set by both of the SSMO and WHO standards and guidelines. The
WHO guideline for Na+
(200 mg/l) is based on taste considerations rather than the impact on human health
(Raveendran and Madany,1991; AL – Redhaiman and Abdel – Magid ,2002).
Microbiological analysis:
Table 4 shows the total count values as Log10 plate count per ml for the three study areas. It may be
observed that only 25% of the samples studied showed negative total viable count. On the other hand, 55% of
the samples were contaminated with coliform bacteria (35% of which are source well water samples and 20%
are Sabeel (public water stands) water samples. The high total viable count of bacteria for the water samples in
the study area indicates that the drinking water in the three communities is highly contaminated; the presence of
coliform in the studied water samples is an indicator of fecal contamination , especially, in public water stands.
This result agrees with a previous study by Abdella et al (2012b), which linked bacterial contamination in public
water stands to a variety of factors : among these are the microbially contaminated hands of water consumers,
children in particular ; handless cups used for drinking exacerbate bacterial transmission by the contaminated
hands that are immersed to various depths into the bulk of the drinking water inside the container ; coverless
water containers also facilitates the bacterial accession into drinking water; especially widely open clay-pots.
Hamad and Dirar (1982) added that dust storms, unattended domestic animals and insects increase the potential
for bacterial contamination as well. Moreover, the absence of the daily cleaning practice, prior to filling the
water containers, allows growth of bacteria, algae and other microorganisms, especially in overlooked locations.
The hoses that are usually used for filling the containers are another potential source of bacterial contamination
(Abdel-Magid ,1997). The mechanism of pathogenic contamination in public water stands is independent of
pollution at the groundwater source. Jensen et al. (2004) reported that drinking water of poor rural communities,
even if it is obtained from ‘safe’ sources, it may become contaminated during storage in the house under non
hygienic and non-sanitary conditions. Pathogenic effects on human life that are related to water were
summarized by Abdellah et al. (2012b) into direct and indirect effects .
IV. Conclusions And Recommendations
Well drinking water quality in both Samrab and Dardog communities is suitable for human
consumption since its physico – chemical characteristics are falling within the permissible limits recommended
by the national, regional and international standards and guidelines. However, well drinking water in Hattab

community is highly saline and is, therefore, not suitable for human consumption. Bacteriological contamination
is evident in the drinking water belonging to all of the three communities studied: 55% of the investigated
drinking water samples were found to be contaminated with coliform bacteria since drinking water is distributed
by random vendors throughout the study area. Therefore, it is imperative to consider connecting these
communities to the municipally treated non - saline drinking water network supply. To avoid microbial
contamination, distribution network pipes should be installed throughout the three communities.
