The present work aims to study the progressive deterioration of groundwater quality over a period of
eight years, in and around the Vrishabhavathi Valley, an erstwhile fresh water stream, now carrying huge amounts of
industrial, agricultural and domestic effluents from the western part of Bangalore metropolis. Groundwater samples were
collected from both the borewells and open wells along the Vrishabhavathi valley watershed during April 2014 from the
same sampling sites, that were chosen for the study in 2006 by these authors and subjected to a comprehensive
physico-chemical analysis and water quality indices were worked out for the entire study area, both for the 2006 and the
present data. The water quality indices have risen alarmingly and it has been found that nearly 67% of the samples are
non-potable and it is seen that this number has risen sharply from 50 % non-potability in study 1 conducted in 2006. This
clearly shows that there is a massive deterioration of water quality in the study span of 8 years, clearly reflecting the
unabated and huge increase in the concentration of pollutants from municipal, industrial and agricultural sources that
have been making their way to the groundwaters of Vrishabhavathi valley basin. The results imply that the groundwater
of all the affected areas are completely unfit for human consumption and needs elaborate and appropriate treatment for
improving its quality.

This time, we're diving into the murky waters of the Fuxnet malware, a brainchild of the illustrious Blackjack hacking group.
Let's set the scene: Moscow, a city unsuspectingly going about its business, unaware that it's about to be the star of Blackjack's latest production. The method? Oh, nothing too fancy, just the classic "let's potentially disable sensor-gateways" move.
In a move of unparalleled transparency, Blackjack decides to broadcast their cyber conquests on ruexfil.com. Because nothing screams "covert operation" like a public display of your hacking prowess, complete with screenshots for the visually inclined.
Ah, but here's where the plot thickens: the initial claim of 2,659 sensor-gateways laid to waste? A slight exaggeration, it seems. The actual tally? A little over 500. It's akin to declaring world domination and then barely managing to annex your backyard.
For Blackjack, ever the dramatists, hint at a sequel, suggesting the JSON files were merely a teaser of the chaos yet to come. Because what's a cyberattack without a hint of sequel bait, teasing audiences with the promise of more digital destruction?
-------
This document presents a comprehensive analysis of the Fuxnet malware, attributed to the Blackjack hacking group, which has reportedly targeted infrastructure. The analysis delves into various aspects of the malware, including its technical specifications, impact on systems, defense mechanisms, propagation methods, targets, and the motivations behind its deployment. By examining these facets, the document aims to provide a detailed overview of Fuxnet's capabilities and its implications for cybersecurity.
The document offers a qualitative summary of the Fuxnet malware, based on the information publicly shared by the attackers and analyzed by cybersecurity experts. This analysis is invaluable for security professionals, IT specialists, and stakeholders in various industries, as it not only sheds light on the technical intricacies of a sophisticated cyber threat but also emphasizes the importance of robust cybersecurity measures in safeguarding critical infrastructure against emerging threats. Through this detailed examination, the document contributes to the broader understanding of cyber warfare tactics and enhances the preparedness of organizations to defend against similar attacks in the future.

ABSTRACT: A Water Quality Index (WQI) provides a single number that expresses overall quality at certain
location and time based on several water quality parameters. The objective of an index is to turn complex
quality data in to information that is understandable and useable by the public. For calculating the WQI
following 11 physico-chemical parameters such as pH, Electric Conductivity, Total Dissolved Solids, Total
Alkalinity, Total Hardness, Chloride, Sulphate, Calcium, Magnesium, Nitrate, Dissolved Oxygen were taken to
assess the impact of pollutants due to anthropogenic activities . The Water Quality Index value for the Ground
water ranges from 50.47 to 63.18 during the monsoon season and 33.74 to 64.69 during the summer season. In
the present investigation the quality of water was found to be good in all the sampling locations in Nellikkuzhy
Panchayat.
KEYWORDS: Ground water, Water Quality Index, Physico-chemical parameters, Water quality standards.
I. INTRODUCTION
Water is indispensable and one of the precious natural resource of our planet. Groundwater is an
important natural source of water supply all over the world. Its use in irrigation, industries and domestic usage
continues to increase where perennial surface water source are absent. The modern civilization, over
exploitation, rapid industrialization and increased population has lead to fast degradation of our environment. To
meet the rising demand it is imperative to recognize the fresh water resources and also to find out remedial
methods for improvement of water quality. The quality of groundwater may depend on geology of particular
area and also vary with depth of water table and seasonal changes and is governed by the extent and
composition of dissolved salts depending upon source of the salt and soil subsurface environment. The
development of growing regions in developing countries is allied several social, economical, environmental and
technical aspect of concerned area along with the study of available, sustainable resources for civilization.
Among all: groundwater is one of the vital resources confined everlasting. In the context of quality and quantity;
ground water fluctuates in variably in its own which reflects the time to time status of groundwater as a whole
for the region.
The quality of groundwater depends on various chemical constituents and their concentration, which
are mostly derived from the geological data of the particular region. Industrial waste and the municipal solid
waste have emerged as one of the leading cause of pollution of surface and ground water. In many parts of the
country available water is rendered non-potable because of the presence of heavy metal in excess. The situation
gets worsened during the summer season due to water scarcity and rain water discharge. Contamination of water
resources available for household and drinking purposes with heavy elements, metal ions and harmful
microorganisms is one of the serious major health problems.
II. LITERATUE REVIEW
Basavaraddi S.B. et al., (2012)[1] made a study on seasonal variation of groundwater quality and its
suitability for drinking in and around Tiptur town, Tumkur district of Karntaka, India. Seven most important
physicochemical parameters such as pH, Total Dissolved Solids (TDS), Total Hardness, Calcium, Magnesium,
Chloride and Nitrate were taken for the calculation of Water Quality Index (WQI) of groundwater. The water
quality index values for the groundwater ranged between 83.9 – 138.5 during monsoon and 67.91 – 130.5 during
summer season. In their investigation the quality of water was found to be good in all the sampling locations in
Tiptur town and surrounding areas.
Srinivas Kushtagi et al., (2012)[2] carried out studies on chemistry and Water Quality Index of
groundwater in Chincholi Taluk, Gulbarga district, Karnataka state of India. Water samples from tube wells,
open wells and hand pumps at various locations were collected and analyzed using standard procedural

methods. The analysis reveals that the groundwater of the area needs certain degree of treatment before
consumption, and it also needs to be protected from the perils of contamination. From water quality index the
water quality of Chincholi taluk was found to be good.
Mishra B.B et al., (2008)[3] studied the water quality index and suitability of water of Kohargaddi dam
at Balrampur district of India. The seasonal variation in water quality parameters in rainy, winter and summer
seasons were studied. The result revealed that the water in the dam is not suitable for irrigation and potable
purposes. Suman Panwar et al., (2012)[4] assessed the groundwater quality in contiguous of integrated
industrial estate at Pantnagar of Uttarkhand. Groundwater samples were collected during different seasons of
summer, monsoon and winter in year 2011-12. Groundwater samples were tested for 11 physico-chemical
parameters by following the standard methods and procedures. Indian standard (IS:10500) for drinking water
quality were adopted for assessment of groundwater quality through calculation of Water Quality Index (WQI).
The result of analysis reveals that the groundwater of the study area becomes contaminated due to
anthropogenic activities.
Ramakrishnaiah C.R et al., (2009)[5] assessed the water quality index for the groundwater in Tumkur
Taluk of Karanataka state, India. Groundwater samples were tested for 12 physicochemical parameters by
following the standard methods and procedures for the calculation of WQI. The results of analysis have been
used to suggest models for predicting water quality. The analysis reveals that the groundwater of the area needs
some degree of treatment before consumption, and it also needs to be protected from the perils of contamination.
Rizwan Reza and Gurdeep Singh (2010)[6] made an attempt to understand the groundwater quality by using
Water Quality Index (WQI) in Angul-Talcher region of Orissa. Twenty four groundwater samples were
collected from open and tube wells during summer and post-monsoon seasons. The study reveals that the
groundwater of a few locations needs some degree of treatment before consumption and it also needs to be
protected from the danger of the prevailing contamination.
Yogendra K. and Puttaiah E.T (2008)[7] in their study calculated the Water Quality index (WQI) of an
urban wtebody, Gopishetti Lake in Shimoga town of Karnataka state. The study aims to ascertain the quality of
water for public consumption, recreation and other purposes. In this study Water Quality Index was determined
on the basis of various physicochemical parameters like pH, Electrical Conductivity, Total Dissolved Solids,
Total Alkalinity, Total Hardness, Total Suspended solids, Calcium, Magnesium, Chloride, Nitrate, Sulphate,
Dissolved Oxygen and Biological Oxygen demand.

IV. CALCULATION OF WQI
Let there be n water quality parameters where the quality rating or sub index (qn) corresponding to the
nth
parameter is a number reflecting the relative value of this parameter in the polluted water with respect to its
standard permissible value. The value of qn is calculated using the following expression
qn = 100[(Vn-Vio)/(Sn-Vio)] (1)
Where,
qn = quality rating for the nth
water quality parameter.
Vn = observed value of the nth
parameter.
Sn = standard permissible value of nth
parameter.
Vio = ideal value of nth
parameter in pure water.
All the ideal values (Vio) are taken as zero for drinking water except for pH=7.0 and Dissolved Oxygen
= 14.6 mg/L.
Calculation of quality rating for pH
For pH the ideal value is 7.0 (for natural water) and a permissible value is 8.5 (for polluted water). Therefore,
the quality rating for pH is calculated from the following relation:
qpH = 100[(VpH-7.0)/(8.5-7.0)]
Where,
VpH = observed value of pH during the study period.
Calculation of quality rating for dissolved oxygen
The ideal value (Vio) for dissolved oxygen is 14.6 mg/L and standard permitted value for drinking
water is 5mg/L. Therefore, quality rating is calculated from following relation:
qDO = 100[(VDO - 14.6)/(5 - 14.6)]
Where,
VDO = observed value of dissolved oxygen
Calculation of unit weight (Wn)
Calculation of unit weight (Wn) for various water quality parameters are inversely proportional to the
recommended standards for the corresponding parameters.
Wn = K/Sn
Where,
Wn = unit weight of nth
parameters
Sn = standard value for nth
parameters
K = constant for proportionality and is given as (Kalavathy et al., 2011)[8]:
K=1/[1/VS1+1/VS2+………+1/Vsn]
Calculation of WQI
WQI is calculated from the following equation
n n
WQI = ∑ qnWn / ∑Wn
i=1 i=1

V. RESULT AND DISCUSSION
The analytical results obtained for different study parameters such as pH, electrical conductivity, TDS,
Alkalinity, Chlorides, Hardness, Dissolved oxygen, Calcium, Magnesium, Sulphate, Nitrate, Iron, Turbidity,
Sodium, Potassium from different sampling locations in monsoon and summer of the year 2013-2014 as
summarised in Table 3 & 4. Permissible limits and recommended agencies are described in Table 2. The results
obtained for Monsoon and summer are discussed below.
pH of water is influenced by geology of the area buffering capacity of water. If the water has pH less
than 7 may cause tuberculation and corrosion while higher the values may produce incrustation, sediment deposits

and difficulties in chlorination for disinfection of water. In the present study pH in all the sampling locations
varied between 5.74 to 7.2 during monsoon and 5.65 to 6.41 during summer. The permissible limit of pH value of
drinking water specified as 6.5 to 8.5 as per IS10500 standards. In some places pH value is slightly less than
permissible limit.
TDS is an important parameter for drinking water and other uses. Water with high solid content is of
inferior palatability and may produce unfavorable physiological reaction in the transient consumer. In the study
TDS was found in the range of 23 mg/l to 125 mg/l during monsoon and 19 mg/l to 189 mg/l during summer.
The permissible level of TDS is specified as 500 mg/l as per IS 10500 standards. Total hardness varied between 16
mg/l to 114 mg/l in monsoon and 12 mg/l to 66 mg/l in summer. Total hardness of water is characterised by
content of calcium and magnesium salts. Calcium was 3.2 mg/l to 22.4 mg/l in monsoon season and in summer 4.2
mg/l to 22.4. In all sampling locations calcium and magnesium concentrations are within the IS 10500 standards.
Chloride concentrations in the all the sampling locations ranged between 5.79 mg/l to 50.16 mg/l in
monsoon and 3 mg/l to 53 mg/l in the summer. The total chlorides observed are below the permissible limits.
Nitrate varied between 0 mg/l to 5.67 mg/l during monsoon season and 0 mg/l to 7.24 mg/l during summer season.
The values are found below the drinking standards. The range of electrical conductivity during monsoon varies
from 46 µ-s/cm to 239 µ-s/cm and during summer season it varies from 36 µ-s/cm to 337 µ-s/cm. In some places
value of electrical conductivity is above permissible limit. The total alkalinity during monsoon varies from 12 mg/l
to 56 mg/l and during summer it varies from 8 mg/l to 60 mg/l. The values are within the permissible limit.
Abnormal concentrations of sulphate may due to the presence of sulphate ore bodies like pyrite, lignite and coal.
The desirable limit of sulphates in drinking water is 250 mg/l. The range of sulphate during monsoon season
varies from 0.325 mg/l to 15.75 mg/l and during summer varies from 2.5 mg/l to 12 mg/l. Turbidity in water refers
to the presence of suspended matter that interferes with the passage of light through water. Turbidity may be
caused by suspended matter such as clay, silt, finely divided organic and inorganic matter, plankton and other
microscopic organisms. Apart from affecting the aesthetics of water, turbidity interferes with effective filtration
and disinfection of water .Limit of drinking water in case of absence of alternate source is 10 NTU, and the
desirable limit is 5 NTU.Water Quality analysis of samples collected indicates that the turbidity ranges from 0 to 2
NTU during monsoon and 1.1 NTU to 13.5 NTU in summer. Dissolved oxygen is the factor that determines
whether the biological changes are brought about by aerobic or by anaerobic organisms. The minimum dissolved
oxygen in disinfection is 6 mg/l. Total dissolved oxygen ranges from 5.6 mg/l to 9 mg/l during monsoon and 6.2
mg/l to 7.8 mg/l during summer. The values obtained are within the permissible limit.
VI. GROUND WATER QUALITY ASSESSMENT
Water quality index (WQI) is one of meaningful approach in ground water and all other type of water
like river, lake and surface water quality analysis. The values of WQI in all sampling locations were summarized
in Table 6&7. The values of WQI in all sampling locations in monsoon and summer season were less than 100
indicating that the water is suitable for human use. On the basis of WQI the quality of water categorised from good
to excellent. Hence the groundwater in the study area is suitable for drinking as well as irrigation purpose.
VII. CONCLUSION
At the outset, the overall WQI values computed in monsoon and summer falls between class I and II of
Table 1, indicates that the water quality is good and suitable for drinking and other domestic purposes. Further the
seasonal values of WQI indicate that in monsoon ground water is more affected than during summer. The seasonal
variations of index values are due to variation in physicochemical characteristics of ground water. Application of
WQI in this study has been found useful in assessing the overall quality of water. This method appears to be more
systematic and gives comparative evaluation of the water quality in different seasons of the year. It is also helpful
for public to understand the quality of water as well as being a useful tool in many ways in the field of water
quality management.
