Death
of River Pandu
in Kanpur
Residents of more than 50 villages situated along
the Pandu river, a tributary of Ganga which passes through Kanpur,
are a disgruntled lot. They are bearing the brunt of the rampant
pollution caused by the draining of ash slurry from Panki Power
Thermal Plant and effluents thrown by a number of industries including
some units of Ordinance into river Pandu. Even worse, tonnes of
sewage are also fouling its water. No wonder, Pandu river which
was known for its crystal clear water two decades back has turned
black. It also stinks. The magnitude of the contamination can
be gauged from the fact
that many of the people exposed to the water are suffering from
a host of skin problems.
Even though the deplorable condition of river
water has been brought to the notice of the authorities concerned,
no action has been taken in this regard. And the poisoning of
Pandu continues. The biggest villain of the piece is the Panki
Thermal Power Plant. According to sources, the plant uses around
3,000 tones of coal and churns out 40 tonnes of fly ash every
day. The ash is dumped in a fly ash pond spread over an area of
two square kilometers. The slurry overflows from the pond and
finds its way into Pandu. An ambitious project for safe disposal
of the fly ash is awaiting sanction from the central government.
The
source of Pandu river is a lake in Farrukhabad. The river runs
for around 120 kilometres and meets the Ganga in Fatehpur. Before
Pandu enters Kanpur, its water is greenish. The tonnes of fly
ash slurry mingles with the river and changes its colour to silvery
grey. Further downstream, when drains of domestic sewage and industrial
effluent mix with the river, its water turns black.
The
plight of the villagers is aggravated once monsoon recedes as
the river water leaves behind a blanket of fly ash on a large
tract of agricultural land. The ash is deposited in the fields
even in the dry season as the farmers use its ash-laden water,
rich in mercury, to irrigate their fields. Large deposits of such
slurry can be found in these fields which have an adverse affect
on productivity. Hapless villagers in the area complain that some
of their lands have become uncultivable. Fly ash slurry makes
the soil less porous and impedes aeration as a result of which
lands turn fallow, claim the farmers. Earlier, the land along
the Pandu river was known to be highly fertile. The kahars, a
local backward community, were leased out the land to grow vegetables
every year. However, due to pollution from Thermal Power Plant,
there are no takers for the land.
Effluents generated by around 6,000 small, medium and big industrial
units located in Panki and Dadanagar industrial areas are also
discharged into the four nalas (storm water drains) that fall
into the Pandu river. Most of these industries
are of electroplating, detergents, chemicals (processing chrome
sulphate also), waste oil processing and some Ordinance units.
Villagers claim that when the Gun Factory releases toxic black
oil into the river, fish die in shoals. Some locals also pointed
out that their cattle die within hours if they consume the river
water accidentally. Despite this, the Central Pollution Control
Board (CPCB) has not undertaken any study of the industrial pollution
in the area, let alone the pollution of the Pandu river. In the
absence of any scientific study, no one knows the exact chemical
composition of the effluent and sewage being carried by the nalas
into the river Pandu.
With the virtual death of Pandu in Kanpur, thousands of villages
have lost a vital water resource. Today the locals fear to even
touch the river water. In case, they venture out into the water
by mistake, they develop boils and rashes on their feet. The toxicity
of the water has forced them to depend on groundwater for their
water needs. However, industrial pollution has taken its toll
on groundwater of the area too. It is apprehended that water at
the depth of around 35 feet might contain dissolved ammonia, nickel,
chromium and fluoride. In such a situation, people are left with
using government-installed handpumps which draw water from a depth
of 100 feet.
Under Ganga Action Plan Phase II (GAP II), the
government proposes to make Pandu river pollution-free. The idea
is to tap the sewage falling into the Pandu river through interception
and diversion and then treat the same. This treated water is proposed
to be used for irrigation.
Against
the backdrop of various lacunae that have turned Ganga Action
Plan into Ganga Inaction Plan, a number of questions need to be
addressed immediately:-
- Under GAP II, three out of the four nalas
falling into Pandu river would be tapped. The fourth nala
(called the IEL drain) exclusively carrying industrial effluent
has been ignored completely. Thus, wouldn’t the river
continue to receive the industrial waste water even after
the completion of GAP II?
- Has any study been undertaken to find out
the chemical composition of the domestic sewage that is proposed
to be tapped and treated under GAP II? There is no segregation
of domestic and industrial waste water and hence, both get
mixed in the drain. This has been corroborated by the recent
test results conducted by IIT-EcoFriends which revealed the
presence of hazardous chemicals and heavy metals in the domestic
sewage reaching the treatment plants set up under GAP I.
- Under GAP II, a 200 million litre per day
(mld) treatment plant is to be set up. The technology approved
for the plant is Upflow Anaerobic Sludge Blanket (UASB) in
which waste is treated through the growth of anaerobic bacteria.
From the experience of 36 mld Common Effluent Treatment Plant
(CETP), set up under GAP I to treat tannery waste water, it
is well-established that the chromium and chemicals as well
as other heavy metals present in the tannery waste stream
affect the functioning of the plant adversely. Shouldn’t
the presence of hazardous heavy metals and other chemicals
be factored in the choice of the treatment technology for
treating sewage mixed up with industrial effluents? Is the
UASB technology appropriate for treating 200 mld of sewage
mixed with industrial waste water?
If these questions are left unanswered, there
is every possibility that GAP Phase II would become a replay of
GAP I. And Pandu river would remain a flowing muck.
