Dear Group Member,

I am grateful to the following members/experts for
their interesting/useful
observations/comments/suggestions on my report
"Modelling of a Coastal Aquifer using FEFLOW"
(available at ftp://ftp.wasy.de/FEFLOW/Goa.pdf ).

(1) Reinhard Zapata (Waterloo Hydrogeologic, Canada)
(2) Krishnaiah C. (India)
(3) S.V.N.Rao (Roorkee, India)
(4) V.V.S. Gurunadha Rao (Hyderabad, India)
(5) Michael Jorgensen (Australia)

I am prompted to seek further suggestions for the
following issues in modelling the seawater intrusion
in coastal aquifers.

(a) How to model the effect of salt pans on
groundwater in coastal areas?

(b) How to incorporate the evaporation from open water
surfaces (e.g. to define time-variant boundary
condition in case of rivers) and evaporation from
shallow groundwater table?

(c) How to model the effect of brackish water in
rivers (due to tidal backwater effect from sea) on
groundwater in coastal areas?

(d) How to develop correlation between resistivity
values and TDS and between resistivity values and
hydraulic conductivity.

(e) Suitability of Kriging, Akima and Inverse Distance
Weighting techniques for interpolation/regionalization
of different parameters/variables.

Any suggestions for the above will be helpful for
extension of this (or similar) study in future.

There is a small errata in the report - title of
figure 7 may be read as "Measured Values of Hydraulic
Conductivity (*10E-4 m/s)" - the multiplier was
missing.

International Training and Research Program:
Groundwater Governance in Theory and Practice

Call for Groundwater Management Fellows

The International Water Management Institute led
Challenge Program on Water and Food project:
“Groundwater Governance in Asia: Capacity Building
through Action Research in the Indo-Gangetic (IGB) and
Yellow River Basins (YRB)” invites Fellows for the
training and research program on Groundwater
Governance and Management.

International Training and Research Program:

“Groundwater Governance in Asia: Theory and Practice”
Period (tentative): November 13, 2007 to March 30,
2008 (inclusive of classroom sessions, cross-cutting
research, field visits and concluding workshops)

Host: International Water Management Institute (IWMI),
New Delhi office; Indian Institute of Technology
(IIT), Roorkee (Uttaranchal) and other partners with
workshops in other basin countries

Basin Countries: Bangladesh, China, India, Nepal, and
Pakistan

Organizer: International Water Management Institute
(IWMI), Sri Lanka and its regional offices and partner
organizations in the basin countries

Background

Globally, groundwater has made tremendous contribution
to human welfare. The Indo-Gangetic basin and Yellow
River basins between themselves use around 300 km3 of
groundwater with value of groundwater used/year
estimated at $13.8 billion. Sustaining the massive
welfare gains groundwater development has created
without ruining the resource is a key water challenge
facing the millions of farmers and water resource
managers of these basin countries. The capacity and
skills of groundwater managers need to be
significantly enhanced to rise to the challenge of
governing the ‘colossal anarchy’ spawned by
groundwater use.

This training and research program sets out to address
the pertinent and very pressing issues of groundwater
management. The rationale is that groundwater is an
‘endangered species’ that is threatened from overuse
and degradation from many sides and that needs and
merits attention, appreciation and protection from all
of its users as well as the public suppliers and
management professionals and institutions.

The course targets people involved in groundwater use
and management at various levels and functions.
Individuals with positions within groundwater
development and management, groundwater research,
capacity building and awareness raising will be
invited in order to foster an inter-disciplinary
understanding, communication, debate and partnership
on the tackling of relevant and practical groundwater
issues in the regions covered by the project.

Who is eligible to participate?

Junior and senior professionals and managers involved
actively in groundwater management and research in the
five project countries (Bangladesh, China, India,
Nepal, and Pakistan, desirably working in basin
regions, Fig.1) are eligible to apply and participate
in the program. Preferably, the applicants should be
affiliated with an established and recognized
organization or institution in the region involved
actively and mandated with groundwater management and
research. Professionals working with Central/ State
Groundwater Boards and related water resources
departments, institutes, universities, INGOs/ NGOs/
donor agencies and all those interested in groundwater
management and governance are encouraged to apply.

People involved in media coverage (content development
and dissemination) on development and environmental
issues and associated with a well-established and
recognized media organization are also invited to
apply.

Course content and training program for Junior Fellows

The Course consists of two parts:

A four week intensive class room course; and
A 12-week training/ crosscutting research program
under live field conditions
The first part will cover theoretical as well as more
case/ region oriented aspects of groundwater, giving
both fundamental introductions to the physical
behavior and characteristics of groundwater, its use
for agricultural production, social sciences,
economics and institutions, policies and governance;
scientific methods in research and field visits.
Delivery of the course shall be through a
well-balanced illustrative and conjunctive treatment
of the various themes through case presentations,
simulation games, field trips and discussion sessions.
There shall be ample opportunities for cross-learning
the regional perspectives of groundwater among the
participants from different countries.

Cross-Cutting Research (CCR)- the practical fieldwork
based component of the course is a 12-week program
that involves three components- five weeks of field
work followed by five weeks of data entry and analysis
and two-weeks of report writing and presentation
workshops. Participants shall be encouraged to go back
to their individual country to do a small but well
planned study or investigation on a specific issue
that either provides them with better knowledge and
tools to pursue their function after the course or it
may be a research topic that fits into a larger
research component of the project that is led by IWMI.
During the first phase, the participants will select
very interesting topics related to resource
characterization and use, sharing mechanisms, formal
and informal water institutions, energy and pricing
mechanisms, groundwater pollution problems. During the
CCR phase the fellows will investigate, through
questionnaires, surveys and data collection, how
groundwater is actually being used and how it relates
to water availability, land use; agriculture, water
and energy policies and other socio-economic factors
in selected regions of the two basins. In the process,
the fellows would directly apply the knowledge gained
at the classroom-training program on the complex
realities of groundwater governance in Asia and
capture the same in the form of group reports/ case
studies and individual theme papers.

Training Program for Senior Managers and Professionals
(Senior Fellows)

The Program for the senior fellows will be of
four-weeks duration and comprise of the following two
components:

One-week exposure to the high level sessions on
management and policy implications of groundwater
governance and the global best practices.

Three-week action research/ study visits to advanced
countries (Australia and/or USA etc. ) in order to
retrieve as much knowledge and information on
groundwater management practices in the host country
to understand some fundamental practices/ processes,
conflicts and challenges faced in groundwater
governance and the specific ways, policies and tools
which have been developed and employed in these
developed countries. Fellows will get a fair
opportunity to interact with a cross section of active
stakeholders in groundwater governance and management
at different levels.

During and at the end of the visit the fellows will
develop individual reports on these learning and
contextualize these experiences for their own settings
in the respective countries. During the first phase of
the Course the senior Fellows visited South Australia
state in Australia and Kansas State in the USA.

Training Program for Media Fellows

Realizing that groundwater is an inadequately
understood, invisible and disregarded water resource
in many respects, general and scientific awareness
raising shall play a key role in future groundwater
management. In order to support this media fellows
with strong interest in development and environmental
reporting are invited to participate in the course.
The program shall follow that of the junior fellows
described above but additionally some specific events
of particular relevance to them shall be organized.
The research program for the media fellows will be
devoted to the development of a couple of news
coverage, development of documentaries and specialized
reports on relevant topics related to groundwater in
their region of interest.

Resource Persons for the Program

Resource persons for the course and training/
crosscutting research components will be drawn both
from the region and from world-renowned international
institutions. The regional experts shall provide
country specific local knowledge; relevance and
applicability of theory and practice under specific
settings and international experts shall strengthen
the program through incorporation of state-of-the-art
knowledge on technology, practices and global best
practices on groundwater governance. Experiences from
the interesting case studies from the first phase
shall also be optimally utilized.

Cost of Course Participation

The cost of the course and training/ crosscutting
research will be covered by the Project, including
traveling (local/ international), course materials,
food and accommodation etc. In addition, a modest
per-diem shall also be provided to cover for
additional incidental expenses. However, it is
expected that the fellows will continue to retain
their association/ liaison with their respective
employers, and hence shall receive their normal salary
and allowances during the duration of the course. The
entire duration of the course may be treated as
deputation/ attachment to the Program.

Course language

The entire course and training components shall be
conducted in English.

Course Certificate and Post-Course Benefits

All successful participants shall be awarded an
international course certificate/ diploma in
partnership with lead participating organizations.
Participants will also have the opportunity to
publish/ co-author their outputs of the action
research in the form of international reports/ journal
articles/ popular articles/ case studies/ media
reports and course sponsored synthesis publications.

Equally, or more importantly, the participants will be
part of a continuing international and inter-regional
community/ society or partnership on groundwater
governance and management that will ensure continued
collaboration and knowledge sharing across various
institutional and geographic boundaries.

How to Apply?

The course participants shall be selected through a
suitably designed process aimed to provide fair
representation to the basin region countries,
professional disciplines/areas of interest, gender,
experience and potential benefits. In order to be
eligible for joining the course and training program,

A completedl application (in the prescribed format)
has to be submitted to IWMI. (For application forms:
Junior and Media Fellows or Senior Fellows)

In addition, for junior and media fellows, a written
formal nomination/ recommendation from a superior of
the organization for the total duration of the course
is required.
A well-drafted concept note, describing a research
topic of interest and relevance to the applicant and
how to address it within the training program should
be developed and submitted along with the application
form.

Senior Managers/ Fellows should submit with their
application a note stating the motivation/ valid
reasons for joining the training program and expected
benefits. Suggestions on the name of a developed
country to potentially visit for the action research
phase may also be indicated.

Last Date for Applications: August 10, 2007

Dear Member,

I am pleased to inform that I have recently completed
the study "Modelling of a Coastal Aquifer using
FEFLOW". A brief introduction of the study is given
below.

Coastal tracts of Goa (India) are rapidly being
transformed into settlement areas. The poor water
supply facilities have encouraged people to have their
own source of water by digging or boring a well.
During the last decade, there have been large-scale
withdrawals of groundwater by builders, hotels and
other tourist establishments. Though the seawater
intrusion has not yet assumed serious magnitude, but
in the coming years it may turn to be a major problem
if corrective measures are not initiated at this
stage. It is necessary to understand how fresh and
salt water move under various realistic pumping and
recharge scenarios. Objectives of the study include
simulation of seawater intrusion in a part of the
coastal area in Bardez taluk of North Goa, evaluation
of the impact on seawater intrusion due to various
groundwater pumping scenarios and sensitivity analysis
to find the most sensitive parameters affecting the
simulation.

For the study, a finite-element model (FEFLOW) was
used for model simulations. The FEFLOW is an
interactive finite element simulation system (Version
5.1) for three-dimensional (3D) or two-dimensional
(2D), i.e. horizontal (aquifer-averaged), vertical or
axi-symmetric, transient or steady-state, fluid
density- coupled or linear, flow and mass, flow and
heat or completely coupled thermohaline transport
processes in subsurface water resources (groundwater
systems).

Salient conclusions of the study are given below.

(1) Presently, seawater intrusion in Bardez taluk of
North Goa is confined only upto 290 m from the coast
under normal rainfall conditions and present draft
pattern. It may slightly extend farther for low
rainfall years.

(2) Seawater intrusion may further advance inland if
withdrawals of groundwater by builders, hotels and
other tourist establishments continue to increase in
the coming years.

(3) Groundwater salinity needs to be continuously
monitored near the coastal area, especially within 2
km from the coast.

(4) Corrective measures with proper planning and
management of groundwater resources in the area need
to  be initiated so that it may not turn to be a major
water quality problem in the coming times.

(5) The model is very sensitive to hydraulic
conductivity and dispersivity values. Field and
laboratory investigations need to be undertaken for
measurement of these parameters for use in further
modelling studies.

(6) The study will guide in making management
decisions to monitor and control seawater intrusion
and planning of groundwater development in the area.

I can send the complete report (in pdf format) by
e-mail to the interested persons. Your comments or
suggestions are welcome.

Kumar

Greetings!

You and your colleagues are cordially invited to attend an exciting
three-day continuing education workshop on aquifer testing methods and
data analysis techniques featuring AQTESOLV at the University of San
Diego in San Diego, California, USA on February 27 through March 1, 2007.

For this course, we are privileged to have Dr. Shlomo P. Neuman from
the University of Arizona join us as a special guest lecturer. He will
discuss his important contributions to the pumping test literature
including the Neuman-Witherspoon (1972) ratio method and the Neuman
(1972; 1974; 1975) method for unconfined aquifers with delayed gravity
response.

Dr. Jim Butler, the 2007 NGWA Darcy Lecturer, will be with us again to
present cutting-edge concepts for designing, conducting and analyzing
slug tests. In addition, Glenn M. Duffield, the developer of AQTESOLV,
will lead hands-on classroom sessions in the computerized analysis of
field data with the AQTESOLV software.

We offer the only courses that feature hands-on computerized data
analysis with AQTESOLV, the world's leading software for the analysis
of aquifer tests (http://www.aqtesolv.com/).

WORKSHOP TITLE:
Advanced Aquifer Testing Procedures Featuring AQTESOLV: New Concepts,
Field Methods and Data Analysis Procedures

WHERE:
Manchester Executive Center at the University of San Diego in San
Diego, California, USA

WHEN:
February 27 through March 1, 2007 (3 Days)

PRESENTED BY:
Midwest Geosciences Group

CONTINUING EDUCATION UNITS:
2.4 CEUs by University of San Diego

CEUs pre-approved for MA LSPs, CT LEPs, TX CAPMs, IA CGWPs, OK USTCs,
DE PGs

COURSE SYNOPSIS:
Conducting pumping tests and slug tests in complex hydrogeologic
settings such as heterogeneous or fractured media is a key element to
site characterization, water resources assessment and remediation
system design; however, poorly planned aquifer testing programs often
lead to suspect data or unanswered questions after the field work is
complete. Even when you are confident of the geologic conditions, you
may have difficulty designing effective tests, running field equipment
or selecting the best available model to analyze the test data. When
can you turn to improve your approach and skills for aquifer testing?

Midwest GeoSciences Group can help! We have designed a powerful

Pricing of ground water mooted - Symposium calls for a
new water policy

Gargi Parsai

NEW DELHI: A national symposium here on "Ground water
governance: ownership of ground water and its pricing"
has called for a new national water policy that should
spell out the demarcation needs between the ownership
and the right to use the ground water resource by
enacting integrated water laws. The thrust of the
recommendations and indeed the symposium, organised by
the Central Ground Water Board and the National
Institute of Hydrology, Roorkee, was to move towards
pricing of ground water, which was likely to mainly
affect farmers.

Calling for a paradigm shift in the role of the
government from provider and financer to facilitator,
the symposium recommended that the ownership of ground
water needed to be vested with the State governments
by making "suitable amendments" to the Constitution to
give effect to the National Water Policy-2002. It has
suggested a "slab system for water pricing structure".
Under this, the economically weaker sections and small
farmers could be charged for water at a subsidised
rate whereas for big (farmers)/users with increasing
demands, the water price could be increased
substantially.

"The governance and ownership and property rights
issues in ground water sector have not been properly
resolved and this is causing anomalies in water
management," said the participants including water
experts, engineers, and bureaucrats.

However, they pointed out that it was difficult to
prescribe "pricing" as one of the tools for better
ground water management, because it was difficult to
price or regulate a resource as the ownership rights
were not clearly defined.

Dear colleagues,

Can anyone explain the exact defenition of sorptivity, escpecially
with regard to dry soils.

In dry soils, when water is applied,
a) the soil drinks the wate very quickly
b)the water intake rate become gradual
c)reaches the steady state.

When we plot the graph of cumulative infiltration against the time,
in very dry soil, the slope for the process 'a' will be the highest.
and this slope is called sorptivity. (mm/hr^0.5). But the soprtivity
value must be less than the steady state infiltration rate - which is
obtained from the slope of the process 'c'. (mm/hr). -------- So,
some where there is mistake.

Can the sorptivity value be higher than the steady state infiltration
value ? then what will be the _expression for saturated hydraulic
conductivity ?

Or in very dry soil, can we take process 'b' as the sorptivity
factor ?

Hope someone will clear the confusion.

Thanks in advance

International Training and Research Program 2006-2007

Groundwater Governance in Theory and Practice

Under the CGIAR Challenge Program on Water and Food
Project:

Groundwater Governance in Asia: Capacity Building
through Action Research in the Indo-Gangetic Basin
(IGB) and the Yellow River Basin (YRB)

Background

Groundwater is a major source of water used in
agriculture as well as for domestic and industrial
water supply in most countries around the world. This
is no exception in South Asia and China where
groundwater has been a vehicle for much of rural and
industrial development over the last half century.
Groundwater is there, groundwater is developed and
used, groundwater generates jobs and income to many
citizens, yet groundwater is not really valued,
monitored, known, and much less managed or governed.

This training and research program sets out to address
the pertinent and very pressing issues of groundwater.
The rationale is that groundwater is an endangered
‘water species’ that is threatened from overuse and
degradation from many sides and that needs and merits
increased attention, appreciation and protection from
individual users as well as private enterprises and
management institutions.

The course targets people involved in groundwater use
at various levels and functions. Groundwater
development and management professionals, groundwater
researchers, and journalists are invited to
participate in the program in order to foster an
interdisciplinary understanding, communication, debate
and partnership on addressing the relevant and
practical groundwater issues in the region.

Program Objective

The overall objective of the training and research
program is to enhance the capacity of existing
institutions involved in groundwater research and
management in the basin states sharing the
Indus-Ganges and the Yellow River Basins (i.e., India,
China, Pakistan, Bangladesh and Nepal) to undertake
more integrated, multidisciplinary and sustainable
approaches to groundwater governance. The program will
train groundwater practitioners in applied research,
and will support lasting, interregional networks of
practitioners and researchers. The program intends to
seed a process of enduring change in the groundwater
management sectors of the states.

Participation

The program targets three types of fellows; 1) junior
and 2) senior groundwater managers and 3) media
fellows from the five countries. The program offers
joint learning forums among the junior and senior
management fellows; as well as separate components
tailored towards particular levels of experience.
Media fellows covering natural resources issues are
included during the training, to improve their
technical knowledge of groundwater as well as their
understanding of key regional issues.

Program Structure

The program is divided into two major phases as
follows:

Phase 1 is a classroom course on theoretical as well
as practical aspects of groundwater governance. This
5-week phase takes place at IIT (Indian Institute of
Technology), Roorkee, India, and other recognized
training institutions in the area, from Oct. 9, 2006.
Phase 2 is an action research program where the
participants acquire skills in groundwater assessment
and management through field surveys and
experimentation (junior and media fellows) and visits
to renown international institutions involved in
groundwater management (senior fellows). This 4 -15
week phase takes place in the five basin states
(junior and media fellows) or overseas (senior
fellows).

The second phase culminates in an annual project
meeting in March, 2007, where all three types of
fellows present findings and results from their
research phase.
Both phases of the program are mandatory in order to
complete the program successfully.

Content, junior fellows

The first phase will cover theoretical as well as more
practical and case-oriented aspects of groundwater. It
will give both a fundamental introduction to the
physical behavior and characteristics of groundwater,
the socioeconomic and institutional and policy
implications as well as the illustrative and
integrative treatment of the various themes through
case presentations, field trips, simulation games and
discussions. The course will combine lecture formats
with interactive discussion seminars.

The second phase consists of a 15 week action research
program, where junior fellows work individually or in
smaller groups on specific topics of relevance and
interest to their professional work. The participants
will go back to their individual country, or another,
to participate in a research program designed by the
project scientists. Typically, the fellows will
investigate, through questionnaires, surveys and data
collection, how users of groundwater behave and how
their behavior relates to water availability, land
use, policies and other socioeconomic factors in
selected regions within the two project basins
(Indus-Ganges and the Yellow River).

Content, senior fellows

In order to cater to senior managers, a shorter and
management-focused program that encompasses one week
of class room training and four weeks of action
research is scheduled. The one- week classroom
training will be concurrent with the last week of the
Phase 1 training program for junior fellows, focusing
mainly on management and policy implications of
groundwater governance. The second phase for senior
fellows is a 4-week research program that showcases
groundwater management frameworks in countries outside
of the region (e.g. the United States, Spain, and
Australia). The senior fellows will collect in-depth
knowledge and information on many facets of
groundwater management including fundamental
processes, conflicts and challenges faced and the
specific ways in which they have been addressed in
that particular country and the potential for transfer
of approaches to the basin states.

Content, media fellows

Realizing that groundwater is a ‘forgotten’ and
disregarded water resource in many respects, general
awareness raising is a must in future groundwater
management. In order to support this, journalists from
print, television, and radio with interests in
environmental and natural resource issues are invited
to participate. Their program follows that of the
junior fellows described above, but with some side
events of particular relevance to them. Their research
program will be devoted to the development of news
coverage or reports on relevant topics related to
groundwater in the areas covered by the junior
fellows.

Timing

The program starts on October 9, 2006 and ends in
March 2007

Five-week class for junior and media fellows, in India
One-week class for senior fellows, in India
Preparation of junior and media fellow action
research, in India Junior and media fellow action
research, in their country Senior fellow action
research, in country outside the basins First annual
project meeting, in India Sunday Indian national
holiday

Who is eligible?

Junior and senior managers and professionals involved
actively in groundwater management and research in the
five project states are eligible to apply and
participate in the program. Preferably, the applicants
should be affiliated with a well-established and
recognized organization or institution in the
region/basins that is involved actively and mandated
with groundwater management and research. Journalists
associated with a well-established and recognized
media organization are also invited to apply.

Target Countries

The program is open to participants with previous
experience in their professional career from the five
basin countries, i.e. India, China, Pakistan,
Bangladesh and Nepal, and who (preferably) reside in
the said countries.

Language Requirements

The program is conducted in English, and fluency in
speaking, comprehending and writing English is a
prerequisite. Candidates whose English is not their
mother tongue must certify their proficiency in
English.

Course Instructors

Instructors for the training and research program will

Sir,

I am doing my M.Tech at IIT Kharagpur. M.Tech project is forecasting
watertable fluctuation using ANN.


  I am taking monthly rainfall, previous month water table depth,
monthly river stage and monthly average temperature as inputs. I
tried with trainbr algorithm. I am not changing the parameters, only
I am changing the number of epochs, since they are taking the
default as 100.  I am scaling the data in to 0-1 domain. Can I use
the same algorithm for 1-, 2-, 3- ....month ahead up to 1 year ahead
forecasting. According to Daliakopoulos et al., (2005), feedforward
NN with LM algorithm provides best results up to 18months forecast
for an area in which groundwater has been steadily decreasing due to
over exploitation. Same situation is in my study area (Konan aquifer
in Japan) also. I have seven years of data (1998-2004). I considered
1998-2001 for training and 2002-2003 for validation. Sir, I thought
that, If I have the data up to 2004, I can forecast for 2005 Jan,
Feb, etc. So for training the data from 1998-2001, for 1 year ahead
forecasting, what i have to give the target values for training?  Is
it the same groundwater values from 1998-2001 or from 1999-2002.

Expecting a reply
Thanking you
Roshni T.

Dear Friends and Colleagues,

I hope you've all been keeping well. I am Ph.D student in Egypt. I am working in
groundwater Hydraulic. I need any references, papers, articles, documents,
...etc in using  evolutionary computational techniques such as Artificial Neural
Networks (ANNs) and Genetic Algorithms (GAs) with groundwater modeling system
(quality and quantity) to develop the computational framework and the
optimization approach. Also, any simple reference about principles of ANNs and
GAs.

   Looking forward to hearing from all.
   Thanks in advance

Dear Colleagues,

For use of high pH water for irrigation and other purposes a very simple
technique known as " Gypsum Chamber Technique" has been developed. In this
technique, high pH water from a tubewell is led into the inlet of a suitably
designed chamber holding gypsum clods. The raw water passes through the
chamber and moves up and finally is discharged through the outlet. Depending
upon the pH thickness of gypsum bed and passage time is designed. This
reaction substantially reduces the pH and makes the water usable. Further
details on Chamber design, size of clods etc. are available.

For tubewell facing frequent encrustation, two things need to be done. First
always use high quality PVC pipes instead of GI pipes which are more prone
to encrustation. Secondly, occasional flushing with sulfamic acid removes
all the encrustation and keeps the well/ pipes in good working condition for
a longer time.

Best regards.

Dear Dr.Susana

   Greetings

   Thank you very much for your information and suggestions. As the water
scarcity is a major problem in Oman, we are planning and searching suitable
method for the treatment of enormously available high pH water. The usage is
not restricted to domestic or agricultural or industries.

   Further, high pH water accelerates encrustation and deposition on well's
screens and casing as well as on pipes. This encrustation impairs well
design within very short time, and reduces the lifetime of wells and
pipelines.  Hence, we are expecting both treatment as well as remediation
(field scale) to solve this problem.

   Once again thank you very much for your information.

   bye for now

   Dear Dr Rajmohan,

The appropriate water treatment for your problem will also depend on
the water's end use.
For small domestic water supply, naturally you would be looking for a
cheap and simple water treatment method and for large water supply you
may have to go for industrial treatment which requires a water treatment
plant.  To give you an idea, the different treatment methods are
explained on this web link
http://www.ext.nodak.edu/extpubs/h2oqual/watsys/ae1045w.htm

Most water softeners substitute Na for Ca.  In your case this will not
work because you already have high Na over Ca.  Your sample is also very
saline which indicates you may have to go for reverse osmosis.  If the
end use for this water is drinking, you will need consult the drinking
water standards in your country to find out what levels you need the
water treatment to decrease those high ion levels.  You could be looking
at a combination of water treatment method.

Hope this helps,
Susana

       Dear Members

     I am looking for a suitable treatment method for high pH water
(greater than 10). It is originated from Oman Ophiolite as the product
of modern, low temperature serpentinization.

    Below, I am giving the range of chemical constituents in this water
samples

   EC (microS/cm) -          500 -20,000

   pH                    -           10 - 13

   HCO3               -           0 -700 ppm
   CO3                  -           2 - 100 ppm

   SO4                  -           10  - 700 ppm

   Ca                    -           1 - 1000 ppm
   Mg                    -           1 - 50 ppm
   Na                    -           40 - 3080 ppm
   K                      -           2 - 622 ppm


   Can anyone please send me the information about treatment methods and
