Six years after Coca-Cola’s bottling plant shut down in India’s southern state of Kerala, the company continues to face allegations claiming it caused the depletion of groundwater and polluted the water resources.
“Before, the food we cooked used to stay for 7 days. But after this plant came, the water became so bad that the food would spoil in a few hours,” says Tangammai, a farm labourer in Kerala’s village of Plachimada where the plant operated.
Crops were also affected, says local farmer Murugan. He grows coconuts just outside the plant’s perimeter and says the trees recovered only after the plant closed.
“The sludge that came out of the plant used to contaminate the rainwater and flood this area,” recalls Murugan. “As a result, the crop yield was reduced and the coconuts used to fall off without ripening. This continued for two years after the plant closed. Things got better after that, and now, you can see, the trees are healthier.”
A recent report by the government-appointed committee in Kerala confirmed that Coca-Cola had caused severe damage to the ecology of Plachimada by over-exploiting the water resources and causing severe water shortage in the area.
Yet Coca-Cola maintains that these charges are false and that, in fact, the company is the one that has been victimized by the political “tug of war” with state elections expected next year.
“There have been many committees, many experts, many reports – in fact – some sponsored by the Kerala government itself, which have come out and said that we have no connection with the local water issues,” says Kamlesh Kumar Sharma, Senior manager of Public Affairs at Coca-Cola in India.
Indeed, there are scientific studies which support the company’s position. In 2003 and 2007 the Central Groundwater Board concluded that the plant was not depleting groundwater. In 2008, the prestigious Indian Institute of Technology Delhi found chemicals like zinc and boron present in water samples around Plachimada, but experts at the Institute say these could not have come from the plant.
“We found that the source areas are away from the plant site,” says Professor A.K. Ghosain, an expert at the Institute.“So the only possibility is that these sources can be in the form of some dump. There is no possibility of something coming from the plant site and moving in that direction.”
Yet this has no effect on the protestors at Plachimada, who are set to continue their campaign against Coca-Cola.
“We will continue our agitation till our demands are met, beginning with the formal closing of the plant, plus compensating the victims and prosecuting the Coca-Cola company,” says Vilayodi Venugopal from the Anti-Coca-Cola Agitation Committee. “We also demand that laws are brought in to ensure that the local government has ultimate control over local resources.”
THIRUVANANTHAPURAM, Kerala, India, February 28 (ENS) - In an unprecedented move, the state legislature of Kerala passed a law on Thursday allowing individuals affected by Coca-Cola's bottling operations in the village of Plachimada to seek financial compensation from the company for ecological damage, water pollution and water scarcity.
The legislation sets up a three-member tribunal to be chaired by a district judge with the power to adjudicate claims for compensation as a result of Coca-Cola's operations in Plachimada.
The tribunal has been granted legal authority to summon individuals and documents, as well as seek and examine witnesses, and the bill legally binds Coca-Cola to follow the directives of the tribunal.
Under the bill, the tribunal shall apply the principles of sustainable development, the precautionary principle and the "polluter pays" principle. Once compensation is awarded, the company shall deposit the entire award amount with the tribunal. All appeals against the tribunal's decisions would go to the High Court.
The legislation is based on the report and recommendations of a High Power Committee whose report on March 22, 2010 holds Coca-Cola responsible for causing pollution and water depletion in Plachimada in the state of Kerala in south India.

Soil pollution is defined as the build-up in soils of persistent toxic compounds, chemicals, salts,
radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal
Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface.
The organic portion, which is derived from the decayed remains of plants and animals, is concentrated
in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over
thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for
agriculture to supply the world with sufficient food.
There are many different ways that soil can become polluted, such as:
• Seepage from a landfill
• Discharge of industrial waste into the soil
• Percolation of contaminated water into the soil
• Rupture of underground storage tanks
• Excess application of pesticides, herbicides or fertilizer
• Solid waste seepage
The most common chemicals involved in causing soil pollution are:
• Petroleum hydrocarbons
• Heavy metals
• Pesticides
• Solvents

Types of Soil Pollution

• Agricultural Soil Pollution
i) pollution of surface soil
ii) pollution of underground soil
• Soil pollution by industrial effluents and solid wastes
i) pollution of surface soil
ii) disturbances in soil profile
• Pollution due to urban activities
i) pollution of surface soil
ii) pollution of underground soil

Causes of Soil Pollution

Soil pollution is caused by the presence of man-made chemicals or other alteration in the natural
soil environment. This type of contamination typically arises from the rupture of underground storage
links, application of pesticides, percolation of contaminated surface water to subsurface strata, oil and
fuel dumping, leaching of wastes from landfills or direct discharge of industrial wastes to the soil. The
most common chemicals involved are petroleum hydrocarbons, solvents, pesticides, lead and other
heavy metals. This occurrence of this phenomenon is correlated with the degree of industrialization and
intensities of chemical usage.
A soil pollutant is any factor which deteriorates the quality, texture and mineral content of the
soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse
effect on plant growth.
Pollution in soil is associated with
• Indiscriminate use of fertilizers
• Indiscriminate use of pesticides, insecticides and herbicides
• Dumping of large quantities of solid waste
• Deforestation and soil erosion

Indiscriminate use of fertilizers

Soil nutrients are important for plant growth and development. Plants obtain carbon, hydrogen
and oxygen from air and water. But other necessary nutrients like nitrogen, phosphorus, potassium,
calcium, magnesium, sulfur and more must be obtained from the soil. Farmers generally use fertilizers
to correct soil deficiencies. Fertilizers contaminate the soil with impurities, which come from the raw
materials used for their manufacture. Mixed fertilizers often contain ammonium nitrate (NH4NO3),
phosphorus as P2O5, and potassium as K2O. For instance, As, Pb and Cd present in traces in rock
phosphate mineral get transferred to super phosphate fertilizer. Since the metals are not degradable,
their accumulation in the soil above their toxic levels due to excessive use of phosphate fertilizers,
becomes an indestructible poison for crops.
The over use of NPK fertilizers reduce quantity of vegetables and crops grown on soil over the
years. It also reduces the protein content of wheat, maize, grams, etc., grown on that soil. The
carbohydrate quality of such crops also gets degraded. Excess potassium content in soil decreases
Vitamin C and carotene content in vegetables and fruits. The vegetables and fruits grown on overfertilized
soil are more prone to attacks by insects and disease.
Indiscriminate use of pesticides, insecticides and herbicides
Plants on which we depend for food are under attack from insects, fungi, bacteria, viruses,
rodents and other animals, and must compete with weeds for nutrients. To kill unwanted populations
living in or on their crops, farmers use pesticides. The first widespread insecticide use began at the end
of World War II and included DDT (dichlorodiphenyltrichloroethane) and gammaxene. Insects soon
became resistant to DDT and as the chemical did not decompose readily, it persisted in the
environment. Since it was soluble in fat rather than water, it biomagnified up the food chain and
disrupted calcium metabolism in birds, causing eggshells to be thin and fragile. As a result, large birds
of prey such as the brown pelican, ospreys, falcons and eagles became endangered. DDT has been now
been banned in most western countries. Ironically many of them including USA, still produce DDT for
export to other developing nations whose needs outweigh the problems caused by it.
The most important pesticides are DDT, BHC, chlorinated hydrocarbons, organophosphates,
aldrin, malathion, dieldrin, furodan, etc. The remnants of such pesticides used on pests may get
adsorbed by the soil particles, which then contaminate root crops grown in that soil. The consumption
of such crops causes the pesticides remnants to enter human biological systems, affecting them
