The
World Bank-aided $44 million Bangladesh Arsenic Mitigation Water Supply
Project
was extended by a year from July 1. Execution of the project will now
continue
with the still unutilized $25 million as bank-funding for the four-year
project
closed on June 30. The project mainly aims to provide alternative
sources of
safe drinking water in the arsenic affected areas.
This
may sound fine on the surface, but if political will is missing, it will not
take us
very far. Political will is the most important factor in dealing with
the
contamination of groundwater by arsenic than anything else, therefore
it is
very important that the government acts decidedly on this issue.
Arsenic
poisoning is already harming the nation’s development as the sick have
become
incapacitated to the extent they can no longer work. This means they
are unable
to contribute to the economic growth of the country.
Although we now know that groundwater
right
across Asia is contaminated and millions and millions of people are at
risk,
nowhere else are people more vulnerable or less able to cope with this
massive
environmental health catastrophe than the people of
To claim that the government and international aid
agencies did not understand the
geographical extent of the problem or the cause of the arsenic
contamination
and could therefore do little more than research the problem is just
skirting
the issue. The role the government has played has been to ignore what
they did
not wish too see thus they left the people to their fate despite the
large
number of victims. Both the media and the public have overlooked or
underplayed
this environmental crisis and public health issue, to our cost. It is more than time to take action but
unless the people recognise that they have a problem, the likelihood of
finding
a solution diminishes.

"After
reading the article on arsenic mitigation by Dr. Zuberi, I think the
'loss of
hope' in
I
think, before giving attention to this issue we need to answer the
following
questions, honestly: - Are people going to involve in the mitigation
process
meaningfully if there is no clinical manifestation? Will it be too late
if we
inform only when clinical manifestation occurs?
-
For the agencies which are depending on the donor funding, are they in
a
position or willing to respond to the complex community situation?
-
Are the agencies working on the issue well coordinated?
-
Do we think arsenic mitigation is just
finding technical solution or a combination technical solution and
overcoming
socially complex issue?
What
will be our answers?"

BELATED
ADMISSION
At a resent seminar organised by Rural
Development
and Cooperative Division, the LGRD Minister siad some 3 crore( 30
Million )
people in Bangladesh have so far been affected by arsenic as it
continues to
engulf groundwater.
He said, skin diseases, cancer, blindness and
physical disability are on the rise among the people living in
arsenic-prone
areas as they are taking arsenic-contaminated water.
He was addressing a national seminar in
Mannan
Bhuyian said
The LGRD Minister hoped that the newly
invented deep
tube-wells would go a long way in mitigating the arsenic problem
through safe
water supply. He said safe water from the RDA deep tube-wells would
also
contribute to socio-economic development of the country by water supply
for
irrigation, fish farming and other purposes. Besides, he said, this
safe water
would also create a favourable atmosphere for food processing,
generating
employment opportunities.
The Dhaka Community
Hospital (DCH)
reports there are 14,000 patients in the country suffering from
clinical
arsenicosis but experts attending a recent seminar in the city warned
that if
people continue to drink ground water instead of surface water, more
people
will be afflicted. They said 55 million people are drinking water
contaminated
by arsenic of 10 microgram per litre.
Other reports say around
25 million
people in 50 districts of Bangladesh are drinking water containing more
than 50
microgram of arsenic per litre which is much beyond the permissible
limit set
by the World Health Organisation (WTO). With more and more people
depending on
ground water, this number is increasing alarmingly.
CLEAN WATER & HEALTH
Access to clean water is
a human right
but it is a sad fact that millions of children are drinking water
contaminated with
high levels of arsenic throughout Bangladesh as the “safe” 'hand tube wells introduced by WHO, UNICEF,
Bangladesh government, NGOs and civil society in the 60s and 70s are no
longer
safe.
Now the cause of
extensive poisoning,
cancer, and death, its toxicity is not only affecting the physiology,
metabolism and normal growth of children it is also affecting protein
synthesis
and DNA repair, causing hereditary changes (mutations) leading to
cancer,
ruining reproductive growth and development and hormone receptors. Thus the future reproductive ability and
normal life of these children have been threatened. It is estimated
that over
80 million Bangladeshis have already been exposed, to arsenic toxicity.
The
majority is below the age of 15.
As the existing approach
to arsenic
mitigate has so far been “top down” with decisions and ”interventions”
decided
at the centre, only a fraction of the affected people have been
provided with
the support they need. More often than not what little support is given
is a “one-off”
effort. What is needed is a sustainable approach through
“community-based
organisations” where community members are given options for
mitigation, and
are given proper support in deciding for themselves which technology
they can
sustain, and then help them to adopt it.
With the help of the NGOs
the methods
adopted can be replicated and diffused throughout many villages.
Schools could
then be provided with safe sources by programmes undertaken by the
children
themselves, thereby learning the methods and introducing them into
their homes
and the homes of neighbors. There would be a need to scale up the CBOs
in those
areas as yet unserved and
link them with local
government,
central government departments and agencies like WHO, UNICEF,
International
NGOs. Thus the approach started from the ‘bottom’ will be small,
effective and
sustainable. It should be appropriate
for villagers, and implemented widely and quickly.
We are working in a
number of villages
and have had wide consultations with the suffering villagers. They are ready to adopt this type of
community-based intervention, but they need institutional support and
methods
that they can adopt as they have no time to waste.
If there is any further delay in assuaging
this problem, as the people experience unthinkable suffering and a slow
painful
death, there will be increased litigation, widespread dissatisfaction,
social
unrest and countrywide instability.
The heads of families
using
contaminated tube well water are feeding it to infants, children and
pregnant
women. Dr Zuberi reports he has seen
little boys and girls who have been affected by arsenic poisoning and
has
observed expectant mothers drinking arsenic-contaminated water.
Research
reports say abortion rates in contaminated areas are significantly
higher than
in others. This means there is a case for mandatory sealing of all
contaminated
wells but before that can be done, a safe water source must be provided
to all
contaminated villages. Awareness building at the community level and
advocacy
at the decision-making level are both important.

ARSENIC TREATED WOOD AND
A
VICTIM
To emphasise the urgency
– and the
dangers – of neglecting the situation we give below an account of the
sufferings of a victim. Although the
source of the poisoning is not the same, the outcome is and we should
take
recourse to this account to motivate us into action.
The victim is a Canadian
who along with
members of her family were poisoned over a period of years by a
neighbor who
insisted on burning CCA pressure treated wood and other chemically
treated wood
in a woodstove in his garage.
CCA wood is still being
reviewed for
its health hazards even though many scientists have warned of the
potential
dangers and advised to keep this wood away from children. How much CCA
in
playgrounds is responsible for the increasing incidents in learning
disorders
and other neurological problems is still to be evaluated but this
particular
victim of arsenic poisoning reports that she has been greatly affected
by
damage to her cognitive skills. Some of these children will never
understand
what has been stolen from them and so needlessly.
ARSENIC IN COW’S MILK
If the arsenic
concentration in the
soil is very high, growing food crops in that particular soil is risky. Even crop establishment may not be possible
if it is planted in highly contaminated soil. In a pot culture with a
soil
arsenic concentration of around 100 mg/kg rice plant died immediately
after
transplantation (unpublished data).
In my research with
arsenic I found a
high accumulation of arsenic in rice straw when rice was irrigated with
As-contaminated water. Rice straw is mainly used as cattle feed in

has provided US$ 375,000 to help the Cambodian Government tackle the
problem of
arsenic contamination in drinking water. The grant has been given under

response to
emerging development issues. UNICEF provided
UNICEF
Cambodia has already supported the testing of over 5,000 of an
estimated 40,000
tube-wells and would assist in the screening of every tube-well in
areas at
risk of contamination. The UNICEF Representative noted that in addition
to
testing wells, the Government, international organisations and NGOs supporting arsenic
mitigation programmes
must also ensure the provision of alternative arsenic-free water
supplies. Part
of the funding provided by UNICEF will be spent on the first trial
programmes
in
A
preliminary assessment of wells in
Detailed screening of
tube-wells was
carried out using NIPSOM field kit and
subsequently the tube-wells were marked with the specified
colors,
thereby rendering them identifiable by the population as either safe or
unsafe,
(red for contaminated tube-wells (arsenic content > 0.05 mg/L),
green for
safe tube-wells (arsenic content < 0.05 mg/L)] . Water from only 12
(twelve)
out of a total 159 tube-wells in the village were found to conform with
the
sub-continental safety limit of 0.05 mg/L, while the remaining 92.4%
tube-wells
were found to be contaminated with arsenic above the safety limit.
At the same time, a
communication
campaign was carried out by way of meetings with different sections of
the
community; group discussions; house to house visits by researchers and
field
assistants; in order to build up public
awareness of the arsenic contamination related problems. These
efforts
are already yielding positive results in
the form of people refraining from using the contaminated water and
using only
the water from safe (green marked) tube-wells as their source of
drinking
water. The results of the tubewell screening is given below:

Although no detailed
health screening
was carried out, a few patients were identified in the village based on
spontaneous, "on the spot" screening by the researchers. Many of them
are already undergoing proper medical treatment. At present the oxidant
and coagulant
based Emergency De-arsenation units are undergoing field trials. After
completion of the field trial the de-arsenation units will be supplied
to the
affected population without access to present safe water sources (i.e.
green
marked tube-wells) in the project area and under supervision of the
'Arsenic
Mitigation Committee'. For a long term solution to the crisis we are
going to
start building a Pond Sand Filter [PSF] in the village, as we prefer
the
utilisation of surface water, especially in the areas of lower delta
plain
where the ponds contain sufficient water even after the lowering of the
'water
table' in the dry season.
A LACK OF MOTIVATION
UNICEF, in cooperation
with the
Ministry of Health Affairs, Department of Public Health Engineering and
BRAC, took
up five such Action Research Projects in different parts of the
country. The
one-year project at Sonargaon Project began in July,1999 and ended in
June,
2000 and the evaluation report is expected to be published soon. A
survey
carried out by UNICEF with the field workers from BRAC showed that 64.5
per
cent of the population were at risk of arsenic-poisoning.
There are 25,048 shallow
hand tubewells
in the area of which 16,171 were found to be contaminated. 8,877 are
certified
as safe for drinking. The survey also showed a sharp rise in the number
of
patients suffering from arsenic-poisoning over the past six months. The
number
of patients rose from 252 to 400 during the
period.
Field workers of BRAC said the number had increased not only due
to
contamination but also because they had not been identified earlier.
Although
70 motivational meetings were held during the six months ending June,
2000,
many of these meetings lacked a spontaneous response from people. In
fact,
around 32 per cent of the population of Sonargoan Upazila are
continuing to
drink contaminated water. Not so long ago these people were asked to
drink the
"pure" tubewell water with the result they no longer have a taste for
any of the alternatives on offer like rain water (which tastes sour) or
water
from ponds and dug wells. Moreover, restrictions by the owners on the
use of
ponds have handicapped this as a source.
The three-pitcher filter
since it was
cheap and its raw materials easily available, proved to be popular. The
tubewell sand filter system could become popular provided they were
made
available to people at a subsidised rate. One tubewell sand filter
costs about
Taka Five Thousand. The old-style dug well is probably destined to be
popular
as prior to the introduction of tubewells, these traditional wells were
the
popular source of pure drinking water. Chinmoy Mutsuddi, an UNICEF
official
said, "We have re-excavated and renovated 35 wells of the area, some of
them dug more than 300 years ago." It was felt that the government
should
pursuade UNICEF to continue funding these projects for sometime more.

PEOPLE ARE
INDIFFERENT TO THE EFFECT OF ARSENIC ON HEALTH
Women came to the
dug-wells to collect
water but on finding them empty they went to the ‘red’ painted tube
wells and
filled their pitchers with the contaminated water. When asked, a woman
said
they have been doing this for several weeks now ever since the dry
season
began.
As the dug-wells did not
contain
water, most households were compelled to drink the arsenic contaminated
water.
Several meetings with villagers indicated that they were aware of the
situation; but said they have no
alternative. Dr. Zuberi advised the villagers to use arsenic
reducing
filters, but when they went to buy them they found they were not
available. As
a consequence their little children,
would-be mothers, young growing sons and daughters, are all forced to
drink
arsenic contaminated water knowing well what the consequences will be.
In many cases villagers are negligent because they do not want to collect water from a distance. Some collect only enough water for drinking but they are still using contaminated water for cooking. In some villages the level of awareness is low, and they tended to give little importance to the possibility of arsenic toxicity.
As solar disinfection of
surface water
(SWD) and solar oxidation and removal of arsenic (SORAS) can be adopted
easily
as a cheap and reliable safe water option in villages, Dr. Zuberi’s
team is
introducing these alternatives in the villages they visited - but it
will take
time and effort to convince the villagers of the reliability and safety
of the
method. They are thinking of adopting a ‘community-based programme to
introduce
SWD and SORAS in arsenic affected villages’ and need the participation,
support
and awareness generating materials (papers, pictures, data, and charts)
for an
effective and immediate outcome.
In the
Mr Abul Hossain said when
arsenic was
detected in his tubewell he re-sunk it three times but failed to find
arsenic-free water. The local Department of Public Health Engineering
(DPHE)
had earlier selected four members of his family for training on arsenic
mitigation and provided three pitcher filters for arsenic removal
however they
did not use the water from these pitchers and instead used the water
from the
contaminated tube-wells!
There have already been
five deaths in
the village (two women and three men) due to arsenic poisoning. Each
and every
member of his family had symptoms of arsenic toxicity on their body:
They had
warts on their hands and feet; swollen belly. Not one of them can now
work as
they feel too weak and short of breath.
Mr. Sohrab Pramanik of
Rajapur village
(Pabna) did not allow workers to paint his tube well ‘RED’ even after
learning
it was contaminated. Workers tested the water twice in his presence but
failed
to persuade him to stop drinking the water with the result that he and
his
family are continuing to drink contaminated water. .
At village Rajarampur
people are
drinking arsenic-contaminated water although they are fully aware of
the
risk. Many mention the distance to clean
wells; crowding; waiting time, labor shortages, and poverty as
difficulties.
Women and children are more aware about the risks of drinking
contaminated
water.
Local CCDB workers
reported that four
of the nine newly dug wells in Chapai Nawabganj and one out of three in
Pabna
are contaminated with arsenic. As dug wells are considered the best
option for
sustainable intervention for the provision of safe drinking water, this
can
only be considered alarming.
Villagers need
organisational support
from within to learn, adopt, and implement the simple methods that need
little
expenditure. What more is needed is an
institution of their own; traditional institutions (samaj, gosthi, even
the
extended family) have broken down. Shall
we be able to do this?
Village Bholadanga has
250 to 300
families mostly land less peasants and some low-caste
cobblers/cleaners. 35
persons have died so far; 70 to 80 are in a bad condition with visible
symptoms; again many among them are young.
The CoB-Arsenic Mitigation Project (AMP) with the help of
Christian
Aid’s fund had tested all the 204 tube –wells in 2002 and found 70%
contaminated with more than 50 ppb arsenic.
Only those affected having visible symptoms on skin have been
provided
with vitamins A,E,C for one month, yet many could not be supplied with
because
of limited funds; less serious patients were not attended for.
The villagers were asked
to drink water
from the ‘green’ tube-wells; 3 old dug-wells have been renovated and 4
dug-wells newly established; many families consider safe-water sources
long
distance away from their homes and often drink water from ‘red’
tube-wells.
While we were discussing arsenic mitigation, a little girl was noticed
washing
hands and then drinking from a ‘red’ tube well; when interrupted she
discontinued and said that the nearest ‘green’ tube-well is several
houses
away. I observed that most of the households do not have enough
water-pots
(earthen-ware pitchers traditionally used by the poor for storing
water) for
day’s supply; one pot is the usual and they go for re-filling when it
becomes
empty; so running out of water and using the nearest tube-well, though
‘red’ is
very common. When asked about this many women talking to us agreed that
this
happens at night or during rains or when the person is very tired and
thirsty;
they also reported that it is difficult to stop the children who have
developed
the habit of drinking water directly from the tube-wells.
In the low-caste
We were surprised to see
that how
lightly they take the arsenic problem. There were other green
tube-wells, there
is a Dug-well provided by CoB-AMP a small distance away but they still
consumed
the contaminated water with their children and infants!
Definitely, there is much
to do about ‘
Another important aspect
of arsenic
mitigation came up during a discussion with local newspaper reporters
and
leaders in Alampur village. There are more than 100 Shallow Tube Wells
(STWs)
in this arsenic–affected village which are using the same aquifer as
the
contaminated hand tube-wells. Many are used almost round the year and
12/14
hours a day. There are 45 STWs in the other affected village. They are
intensely used during the Boro (dry season) paddy cultivation and must
have
been importing tons of arsenic to the surface! There is no soil test
done yet.
When I requested them as leaders of the village why not introduce
‘wheat’
during winter (Boro) season crop which require much less water, they
said that
they do not have a suitable HYV wheat for their region! Why not local
variety?
Yield less they said. Why not maize or vegetables?
They agreed that that could save soil and
produce some return. I mentioned that intensive Paddy cultivation is
the most
damaging agricultural activity and that we must reduce rice consumption
and
cultivation if we want to save our environment. The villagers present
were
motivated to consume less rice – they are used to taking rice meals
thrice a
day (if they can afford it), little vegetables and fruits; other major
items as
WHEAT / POTATO with lots of vegetables and fruits which can save them
from
Arsenic and also help save their environment.
The community workers of
CoB are doing
their best but had very little support for meeting the needs; Christian
Aids
support is running out this year. They are afraid whatever little they
are
doing now will be stopped soon. What a pity!
Dr. Zuberi's
recommendations for
removing arsenic contamination are as follows:
- All options for safe
drinking water
should remain open; they should be standardized and monitored, but
availability
and affordability of viable options is more important. At any cost the
people
MUST get safe water.
- Labeling tube wells red
should be
compulsory and there should be legal obligation; it is better to remove
or seal
them.
- Mitigation and
awareness creation
should be an ‘emergency crisis’ activity, all possible resources and
persons
should be involved.
- Participation of
village people and
women is essential, a ‘must’ for rapid success.
- Action is what is
needed.
Policymaking and decision taking has already eaten up too much valuable
time
and caused irreparable losses.
-
Nutritional intervention and removal of arsenic from the body are also
much-needed interventions. This will save the body from the arsenic
load and
future harm and enable the affected people to regain their ability to
work,
otherwise millions will lose their jobs and work affecting the
country’s
economy and creating a burden on society.
BRAC AND UNICEF
BRAC and UNICEF in a bid
to tackle the
arsenic menace in different parts of Sonargaon upazila have been
pursuing the
treatment of surface water with: Pond Sand Filter (PSF), Rainwater
Harvesters
(RWH), treatment of ground water with home-based filters and use of
shallow
ground water through dug-wells. A number
of alternative safe water
options are
now in operation as demonstration units to raise the level of awareness
in the
community.
