Air pollution on the rise in Kerala: Report Air pollution on the rise in Kerala: Report Dr George Mothi, a senior pulmonologist at Medical Trust hospital, Kochi says that there has been a rise in the number of patients reporting with respiratory diseases. Oct 15,
The raw materials consumed during these activities has resulted in the dwindling of non renewable resources and accumulation of wastes. These wastes are indescriminately disposed and as a consequence the water air and land becomes more polluted.
Added to these the recurrence of drought and water scarcity and sand mining resulting in the death of rivers and rivulets, change in land use pattern leading to severe soil erosion, depletion of biodiversity, increasing incidence of natural disasters like earth quakes, landslides and so on are undermining the once serene and splendid environment of this 'God's own land.
Deterioration of water quality: The major water quality problem associated with rivers and open wells is bacteriological pollution. The dumping of solid waste, bathing and discharge of effluents also create problems.
Low pH, high iron etc, are common in well waters in the laterite covered midland areas. High concentrations of fluoride over the permissible levels have been reported from certain parts of Palakkad and Alleppey districts.
The salinity level is frequently high in the coastal belt.
Clean water has become a precious commodity and the quality is threatened by activities such as agricultural discharge, domestic sewage, municipal solid waste burial grounds and industrial effluents in Kerala. Managing and protecting surface and groundwater is essential for sustaining life.
A continuous water quality monitoring program and proper water safety plan are essential to preserve and improve the water quality. Groundwater Quality Problems The ground water quality problems of Kerala are associated with mineralogical origin, human interference, industrial effluents, agricultural wastes, municipal solid waste burial grounds etc.
Generally, the ground water problems in Kerala in coastal areas are due to the presence of excess salinity, high fluoride, hardness, and coliforms, low pH, high iron content, high TDS Total Dissolved Solids and excess chloride concentration. The ground water problems due to high fluoride content are reported from Palakkad and Alapuzha districts of Kerala.
Ground water contamination due to industrial pollution has been reported from places of Cochin, Palakkad some parts of Kollam, Kozhikode and Kannur. The municipal and industrial landfills operating in various parts of Kerala is causing great concern to the quality of ground water.
Kerala since early nineteen eighties have been resorting to tube well construction to take underground water even from feet deep tube wells.
Water that took over 10, years, to accumulate in underground aquifers has been mined dry in the last 30 years with consequent environmental problems such as drying up of nearby wells, intrusion of salt water due to lowering of underground water level, and drying up of a large number of tube wells themselves.
Over exploitation of ground water resources can be tackled through a process of intensive education on the adverse impacts and resorting to the merging practice of rain water harvesting. At the macro level, it is very necessary to dig tanks and canals, plant trees and collect rainwater.
At the micro level, each individual should avoid water wastage through simple measures like tightening taps, maintaining delivery lines, using low HP pumps and motors and collecting and storing rainwater.
Appropriate ground water laws should be framed to regulate indiscriminate exploitation of the limited ground water availability in the state. Death of the rivers Kerala, a narrow coastal strip, is nourished by a large network of 44 living rivers. Our rivers die due to a variety of reasons such as lack of rain,deforestation, unchecked and indiscriminate mining of sand ,encroachment of the banks by unautorised settlers, Wet land filling, construction of dams and barrages, deepening of land along the river banks to manufacture bricks, indiscriminate use of fertilizers and pesticides, pollution caused by the discharge of effluent from industries, civic bodies and domestic wastes, salinity intrusion, soil erosion, siltation, dam construction and deforestation and drying up of rivers in the summer season.
The rivers of Kerala have been increasingly polluted from the industrial and domestic waste and from the pesticides and fertilizer used in agriculture. Industries discharge hazardous pollutants like phosphates, sulphides, ammonia, fluorides, heavy metals and insecticides into the downstream reaches of the river.
The major rivers namely Periyar and Chaliyar are apt examples for the pollution due to industrial effluents. It is estimated that nearly million liters of industrial effluents reach the Periyar river daily from the Kochi industrial belt. The death of rivers has resulted in severe shortage of drinking water and drought conditions in the state.
Fresh water lakes face a number of adverse environmental impacts due to many factors such as draining the water from the lake, reclamation of low lying areas for agriculture, increasing the depth of the lakes due to siltation as a result of soil erosion ,using the lake areas for building houses, construction of bunds in the lakes for pisciculture growth of algae in water, pollution thorugh fertilizers, chemicals from agriculture and disposal of wastes.
The greatest single factor that has contributed to the destruction of river ecology in Kerala is indiscriminate unscientific sand nining from rivers. All the 44 rivers in Kerala are facing a big crisis because of sand mining.
The construction boom, fueled by the inflow of remittances from non-resident indians and the inherent nature of people to construct ostentatious residential buildings, leads to indiscriminate mining of sand from rivers.Plastic pollution: In Kerala, which is a consumer State, there is an unprecedented increase in the use of plasticsthat cause deadly pollution whose ill effects are irreversible.
The major chemicals that go into its making are highly toxic and cause serious threats to public health. The harbour in Kochi, the economic capital of Kerala and India's second port, is so badly polluted by effluent that local people rarely swim or fish in it.
