Children are more affected.

Contaminated community water source with low pH value

Polluted river bed.

Atmosphere is also polluted.

Black river.

Dust is every where.

The health hazards, degeneration of the health conditions of the people especially tribal women and children and water contamination is one of the most serious impacts of coal mining in Jharkhand.

Jharkhand is an area of abundant coalmines. Most of the coalmines are situated in Hazaribag, Chatra, Palamau, Rajmahal, Dhanbad and Ranchi district. Mighty Damodar River and its tributaries flow through these coalmines.

Jharkhand is the homeland of over a dozen indigenous communities, the major ones being the Santhals, the Mundas, the Oraons and the Hos. Most of their populations are concentrated around the coal mines area.

Today, the picture of Damodar River or Damuda, considered a sacred river by the local tribals, is quite like a sewage canal shrunken and filled with filth and rubbish, emanating obnoxious odours. This river once known as “River of Sorrow” for its seasonal ravages, has now turned into a “River of Agony” from the environmental point of view.

Due to extensive coal mining and vigorous growth of industries in this area water resources have been badly contaminated. The habitants have, however, been compromising by taking contaminated and sometimes polluted water, as there is no alternative source of safe drinking water. Thus, a sizeable populace suffers from water borne diseases.

The Damodar river basin is a repository of approximately 46 per cent of the Indian coal reserves. A high demographic and industrial expansion has taken place in last three decades in the region. Exploitation of coal by underground and open cast mining has lead to a great environmental threat in this area.

Besides mining, coal based industries like coal washeries, coke oven plants, coal fired thermal power plants, steel plants and other related industries in the region also greatly impart towards degradation of the environmental equality vis-a-vis human health.
The most affected part of the natural- resources is water in this region and thereby human health.

Damodar is a small rainfed river (541 km long) originating from the Khamerpet hill (1068 m), near the trijunction of Palamau, Ranchi, and Hazaribag districts of Jharkhand. It flows through the cities Ramgarh, Dhanbad, Asansol, Durgapur, Bardwan and Howrah before ultimately joining the lower Ganga (Hooghly estuary) at Shayampur, 55 km downstream of Howrah. The river is fed by a number of tributaries at different reaches, the principal ones being Jamunia, Bokaro, Konar, Safi, Bhera, Nalkari and Barakar.

The total catchment area of the basin is about 23,170 km of this, three- fourth of the basin lies in Jharkhand and one-fourth in West Bengal. The major part of the rainfall (82%) occurs during the monsoon season with a few sporadic rains in winter. Damodar basin is an important coal bearing area and at least seven coal fields are located in this region.

High increase in the population i.e. from 5.0 million (1951) to 14.6 mil- lion (1991) has been observed during the last four decades which is the out- come of the heavy industrialization in this basin mainly in coal sector.

Due to easy availability of coal and prime cooking coal, several thermal power plants, steel plants have grown up. Discharge of uncontrolled and untreated industrial wastewater, often containing highly toxic metals is the major source of pollution of Damodar River.

Mine water and runoff through overburden material of open cast mines also contribute towards pollution of nearby water resources of the area. Huge amount of overburden materials have been dumped on the bank of the river and its tributaries, which finally get spread in the rivers especially in the rainy season. These activities have resulted in the visible deterioration of the quality of the river water.

The large scale mining operations going on this region have also adversely affected ground water table in many areas with the result that yield of water from the wells of adjoining villages has drastically reduced. Further, effluents discharged from the mine sites have also seriously, polluted the underground water of the area.

Mine water does not have acid mine drainage problem. It may be due to the fact that coal deposits of this basin are associated with minor amounts of pyrites and contain low Sulphur. Iron content in this water is found in the range of 1 to 6 mg/1. Though it is not alarming but it may be toxic to some aquatic species. Mine water is generally bacterially contaminated which is clear from the value lying in the range of 100 to 2500.

Heavy metals like manganese, chromium, lead, arsenic, mercury, floride, cadmium, and copper are also found in the sediments and water of Damodar river and its tributary like Safi River. Permian coal of this area contains all these toxic elements in considerable amount. Presence of lead is high above the alarming level i.e. 300 ppm (parts per million) in the coals of North Karanpura coal field.

The study warned that long term exposure to the lead present in that area might result in general weakness, anorexia, dyspepsia, metallic taste in the mouth, headache, drowsiness, high blood pressure and anaemia etc.

The Damodar sediments are deficient in calcium and magnesium and rich in potassium concentration. Titanium and iron are the dominant heavy metals followed by manganese, zine, copper, chromium, lead, arsenic, and mercury. Other heavy metal like strontium shows more or less uniform concentration throughout the basin. Average concentration of strontium in the sediments of the river is 130 ppm. Silica is also high in the sediments of Damodar River and its tributary. The value is 28ppm.

Arsenic in the water ranges from 0.001 to 0.06 mg/1, mercury ranges from 0.0002 to 0.004 mg/1, floride ranges from 1 to 3 mg/1.

It is obvious that due to extensive coal mining and vigorous growth of industries in this area water resources have been badly contaminated. The habitants have, however, been compromising by taking contaminated and sometimes polluted water, as there is no alternate source of drinking water. Thus, a sizeable populace suffers from water borne diseases.

As per the heath survey of the local people, the most common diseases are dysentery, diarrhoea, skin infection, worm infection, jaundice, and typhoid. Dysentery and skin infections occur in high percentage in the area. If proper steps are not taken up the total population mostly tribals will be on the verge of extinction.

The Agaria tribe and other tribes that inhabit the coalfields of North Karanpura and East Parej, India are faced with severe water contamination. In East Parej, more than 80% of the community lives in poverty. Water for the community comes from hand pumps, dug wells, local streams and rivers. In some areas, mine water and river water is supplied through pipes. But most people are dependent on other sources - which are contaminated - for their water needs. Women and children in these areas have to travel more than 1 kilometer to fetch safe drinking water. Most villagers are left with no choice but to drink contaminated water. Dug wells are generally dried up during the summer and winter. Natural drainage is obstructed and diverted due to the expansion of mining. Villagers in these areas have no concept of how to preserve and purify rainwater.

Our longevity has reduced drastically, said Phulmani Kujur a 38 year old women of East Parej coal field. We avoid taking bath everyday, there are a gap of 5 to 10 days, and do not drink water adequately due to water pollution, said Mahesh a Santhal Tribe of the same village.

Study reveals that average longevity of women in East Parej coal field was found to be 45 and in most of the villages only one or two women had crossed the age of 60. In North Karanpura coal field average longevity of male is 50 years and that of female is 45 years.

The number of deaths in a period of five years, in East Parej, also reveals shocking figures in Dudhmatia village: 6 out of average 80 people, in Agariatola village: 12 out of average 100 people, in Lapangtandi: 13 out of average 115 people, and in Ulhara: 9 (seven were children) out of average 80 people.

Villagers of Agariatola complain that their only source of drinking water has been damaged due to dumping of overburden and expansion of open cast mine. Villagers have no substitute but to drink the water of well provided by the miners which according to the villagers is not good in taste with foul smell and yellow colour. Villagers of Dudhmatia of the same coal field complained about foul smell present in the water of the only hand pump.

Average kilometers travel by the villagers to retrieve safe drinking water is 1 to 2 kilometers. In summer season we have to travel even more to have safe drinking water, alleged women of the affected areas. Sometimes organizations supply us the water through tankers but they are not sufficient, said villagers of the East Parej, North Karanpura and South Karanpura coal field.

In the absence of even primary hospital and doctors in East Parej (there is only one hospital run by Central Coalfields Limited) villagers are more dependent on the quacks as they are the regular visitor in the remote area.

Our children are the most affected due to living in such unhygienic conditions and filth, said villagers of the North Karanpura coal field, one of the biggest coal mines of the area.
These are one of the most common situations in all the coal mines area of Jharkhand. Most of the population in North Karanpura coal field is dependent on Safi River for drinking and other domestic purposes. This river is polluted because of the coalmines waste dumped along the banks of the river at different locations. Water of the area is contaminated with toxic metals like arsenic and mercury. Manganese has crossed the toxic level ( 3.6 milligram per liter against the permissible level of 0.5 mg/l.). According to WHO (World Health Organization) high manganese may affect with the symptoms like lethargy, increased muscle tone and mental disturbances.

Health survey done among the boys and girls in a local school it was found that majority of the children (both tribal and non-tribal) are lethargic may be due to inhalation of coal dust and consumption of contaminated water containing high manganese.

In the coal fields of Jharkhand most of the tribal women are employed in secondary activities such as loading and unloading of the coals. According to Chotanagpur Adivasi Sewa Samiti, a NGO working in Hazaribag district, constant contact with dust pollution and indirectly through contamination of water, air, etc. cause severe health hazard to women workers. As majority of the women workers are contract labourers, and paid on daily wage basis there is no economic security or compensation paid due to loss of workdays on account of health problems. Even during pregnancy women has to work in hazardous conditions amidst noise, air pollution that have adverse affects on their offspring.

Malaria is very common. It is found that there are numerous ditches, stagnant mine water, and open tanks breeding all the species mosquitoes. Majorities of the death were attributed to malaria. Next come the skin diseases such as eczema, rashes on the skin etc. it may be due to lack of care and cleanliness or due to the presence of nickel in drinking water. In some area like East Parej high nickel (0.024 mg/l) have been reported in the water. According to WHO nickel is a common skin allergen.

Many especially children of the coal fields suffer from dysentery and diarrhoea. According to the residents of the coal field, it is because of consuming contaminated water. About 60% of the local people are affected with seasonal allergies. Other diseases found were tuberculosis, headache, joints pain (pain begins at the age of 5 to 10 years, especially in North Karanpura), gastric, cough and cold and asthma.

When asked from the villagers in East Parej and North Karanpura about what do they think about future, they replied situation is going to worsen. They are not very confident about their life span. There is always a threat of displacement due to expansion of coal mining, which finally affects their longevity.

Fluoride, arsenic, nickel, sulfate, and manganese pose the biggest threats to water sources in the region. They have been shown to cause adverse effects when consumed over a long period of time. Health care facilities can improve the situation immensely, but it is more desirable to maintain the philosophy that prevention is better than the cure. Medical checkups can be adopted to improve the situation. Installation of pollution control equipment is needed for monitoring and analyzing pollution data. Seeing that nearly all the water sources under study are contaminated, the only short term solution for safe drinking water is rain water harvesting. Indigenous methods, such as disinfecting and purifying water with the help of medicinal plants, can be adopted for purifying water in ways that are cost efficient.

The international community can also help by providing funds to carry out research and analysis of the problem in more detail. Publishing these results can help other communities around the world figure out the best methods for improving water quality. Awareness programs should be given major importance.

Problems of Urban growth.

Ranchi the capital city of Jharkhand State in India is expanding both vertical and horizontal resulting in lots of problem.

by

Dr. Nitish Priyadarshi

As more and more people leave villages and farms to live in cities, urban growth results. Urbanization occurs naturally from individual and corporate efforts to reduce time and expense in commuting and transportation while improving opportunities for jobs, education, housing, and transportation. Living in cities permits individuals and families to take advantage of the opportunities of proximity, diversity, and marketplace competition.
People move into cities to seek economic opportunities. In rural areas, often on small family farms, it is difficult to improve one's standard of living beyond basic sustenance. Farm living is dependent on unpredictable environmental conditions, and in times of drought, flood or pestilence, survival becomes extremely problematic.
Cities, in contrast, are known to be places where money, services and wealth are centralized. Cities are where fortunes are made and where social mobility is possible. Businesses, which generate jobs and capital, are usually located in urban areas. Whether the source is trade or tourism, it is also through the cities that foreign money flows into a country. It is easy to see why someone living on a farm might wish to take their chance moving to the city and trying to make enough money to send back home to their struggling family.
There are better basic services as well as other specialist services that aren't found in rural areas. There are more job opportunities and a greater variety of jobs. Health is another major factor. People, especially the elderly are often forced to move to cities where there are doctors and hospitals that can cater for their health needs. Other factors include a greater variety of entertainment (restaurants, movie theaters, theme parks, etc) and a better quality of education, namely universities. Due to their high populations, urban areas can also have much more diverse social communities allowing others to find people like them when they might not be able to in rural areas.

Clearly, urban settlements differ greatly in size, as mentioned by their populations. Is there a Theoretical maximum and an optimum size? Criffith Taylor and others believe that the ultimate size may be fixed by the increasing difficulty of obtaining enough water to supply unduly large numbers concentrated in a small area, while Lewis Mumford and similar authors think that the continued growth of very large cities not only produces more administrative problems than benefits. This also paralyses rather than furthers social relationships and phenomenally raises central land values, so much that land ceases to be adaptable to new needs.

Views on the optimum size of a city have altered with the march of history. Plato believed that most desirable size was 5,000, a figure which would allow everybody to hear the voice of an orator and so participate in active political life and develop varied social relations. Late nineteenth – century garden city enthusiasts in Britain thought that towns of 30,000 to 50,000 would be large enough supply all necessary human needs, whether medical, educational, social, economic or cultural.

Towns could not come into being until the surrounding countryside was capable of providing a food surplus in the past. Due to modern transport and large surpluses in many parts of the world, towns generally have little difficulty in obtaining food, even from far distant lands. Developing countries may lack the capital to give all their town folk an adequate diet, and even in developed countries there are sporadic temporary shortages, owing to failures in economic planning, poor harvests, dock strikes and traffic hold-ups occasioned by excessive rain, snow, floods, droughts etc.

The problem of water supply is more permanent and applies specifically to cities. It is becoming increasingly serious even in advanced countries which certainly have no problem in paying for the water they consume. The root of the problem lies in the fact that 98% of the earth’s surface water is contained in the salt oceans and in ice-caps. The remainder is unevenly distributed and often polluted. Over half is needed for agriculture, about a third for industry, 10 percent for domestic use.

Many cities, especially in developing countries, lack a clean supply of fresh water. In India, e.g., less than a third of the urban population has access to pure water, and the main reason why water borne diseases are rampant. Even when people are provided with purified water for drinking, they usually wash themselves and their clothing in contaminated supplies.

The demands made on water by urban industries, power stations and homes are growing at a more rapid rate than the growth of population. Many wells do not yield enough water, river pollution, like Ganga, Damodar etc. in India, is a continuing evil, and the remaining water resources- mostly in thinly populated highland areas of abundant rain- are far from many consuming centres.

After being separated from Bihar, Jharkhand state of India is now fast growing in terms of business. Ranchi the capital city is expanding both vertical and horizontal resulting in lots of problem like irregular electric supply, water supply, ground water depletion, air pollution, noise pollution, municipal waste disposal, failure of drainage systems, traffic jams etc. Surface waters are being contaminated. Seasonal diseases have also multiplied. More and more people are concentrating in the city flats which has raised the land values many fold. Ranchi earlier known as the summer capital has now become the heat furnace during summer. It is all due to the unplanned expansion of the city.

The urban heat island has become a growing concern and is increasing over the years. The urban heat island is formed when industrial and urban areas are developed and heat becomes more abundant. In rural areas, a large part of the incoming solar energy is used to evaporate water from vegetation and soil. In cities, where less vegetation and exposed soil exists, the majority of the sun’s energy is absorbed by urban structures and asphalt. Hence, during warm daylight hours, less evaporative cooling in cities allows surface temperatures to rise higher than in rural areas. Additional city heat is given off by vehicles and factories, as well as by industrial and domestic heating and cooling units. This effect causes the city to become 2 to 10 degree F (1 to 6 degree C) warmer than surrounding landscapes. Impacts also include reducing soil moisture and intensification of carbon dioxide emissions.
Owing to population growth, poor levels of hygiene, and increasing urban poverty, the urban environment in many developing countries is rapidly deteriorating. Densely packed housing in shanty towns or slums and inadequate drinking-water supplies, garbage collection services, and surface-water drainage systems combine to create favourable habitats for the proliferation of vectors and reservoirs of communicable diseases. As a consequence, vector-borne diseases such as malaria, lymphatic filariasis and dengue are becoming major public health problems associated with rapid urbanization in many tropical countries

Another change that has occurred after the oil crisis of 1973 is the vertical growth of large cities. People who were living in suburbs found it costly to travel to the city. The open spaces within the city got filled up by the construction of high rise buildings. Large bungalows and old residences were demolished and high rise buildings have come up both as commercial complexes and as residential flats. Many rich families are migrating from the suburbs to flats or apartments near the city centre. The vertical expansion of cities poses further problems in water supply, sewage disposal and traffic congestion on the roads. Traffic causes urban noise, air pollution, stress and strain in an individual.

One solution for both lateral expansion and vertical growth of a city is to develop satellite towns at a distance of 40 to 50 km from the city. The satellite town will not be a mere residential town to accommodate commuters. Such a satellite town will be both a place of work and a place of living.

Arsenic alarm in Bihar and Jharkhand Villages of India.

Bihar and Jharkhand is facing one of the gravest natural disasters in the form of arsenic contamination of ground water.

by

Dr. Nitish Priyadarshi

Thousands of people living in over hundreds of villages in different district of Bihar and Sahebganj district of Jharkhand state in India are facing serious threat to their health due to alarmingly high quantity of arsenic present in the underground water.

Bihar is facing one of the gravest natural disasters in the form of arsenic contamination of ground water. In the first detailed study of ground water quality, the Department of Environment and Water Management, A.N.College, Patna, has already submitted Interim Reports to PHED and UNICEF about the alarming findings on arsenic poisoning cases in the districts of Patna, Bhojpur, Vaishali and Bhagalpur. The study was conducted from April 2004 to May 2006, the study area being confined to 10 kms. wide belt along the Ganga river as per the instructions of PHED and UNICEF.

According to Dr.Ashok Ghosh, Principal Investigator of Project Arsenic, Dept. Of EWM, A.N.College, these findings are just the tip of the iceberg, as more contaminated aquifers are waiting to be detected in the remaining parts of the state. The water quality testing was done initially by Field Test Kits and then confirmed by AAS or UV Spectrophotometric tests. Epidemiological studies indicate that drinking water having more than permissible arsenic levels of 10 ppb. increases the mortality rates as arsenic is a bio-accumulative toxin.

Persons suffering from arsenicosis have not yet responded to known treatment procedures. The high the intake of arsenic, along with under nourishment and lack of medical help have worsened the lives of the population in the arsenic affected rural areas. Arsenic can also contaminate standing food crops if it is present in the soil and soil water. As Bihar Plains are highly fertile and its crops are marketed to many distant places, apart from being locally consumed, it becomes imperative to test the levels of arsenic in the food chain too. What is worrisome is that arsenic contaminated ground water tables have abrupt occurrences both over time and space. This explains why a public hand pump in village Ramnager in Maner tested 30 ppb. in the post monsoon period and more than 60 ppb. in the month of May. Also arsenic manifestation exists at different levels in different areas. In north-west Maner, arsenic contaminated hand pumps have a shallow depth of between 60 to 80 feet in the diara belt.

In Bhojpur, the depth of contaminated aquifers goes down to 150 feet away from new diara land, while in Vaishali, arsenic is found in the shallow and middle aquifers at an average distance of 5 km. away from the river bank. Regular monitoring of drinking water from hand pumps is immediately required as a part of the mitigation strategy. Patna, the first district to be covered, revealed pockets of high arsenic contamination, above the acceptable limit of 10 ppb., in 171 villages in Maner, Danapur, Sampatchak, Barh, Bakhtiarpur, , Fatuha, Khusrupur, Phulwari, Mokama, Pandarak and Patna City.

1060 village hand pumps were arsenic contaminated The highest AAS reading of arsenic level in government hand pump water is 724 ppb. in village Naikatola in Maner, 450 ppb. in Kasimchak village in Danapur, 553 ppb. in Ghiaspur Mahazi and 538 ppb. in Kala Diara, Bakhtiarpur,, and 484 ppb. in Malahi Banda village in Barh. Sampatchak Block has low contamination levels of below 50 ppb. over a larger area in most of the villages. In Bhojpur, the highest AAS test readings are 1861 ppb. and 1064 ppb. in Pandey tola, Barhara Block, a situation far more serious than the one represented by the much-touted village Ojhapatti of Shahpur Block. Out of the 6292 hand pumps tested, 47.70 % were arsenic contaminated hand pumps. In Barhara, 62.84%, in Udwantnagar 59.39%, in Shahpur 40.41%, in Behea 37.17%, in Koilwar, 29.20%, and in Ara 25.88% of Block level hand pumps were arsenic contaminated. In Vaishali, all the Blocks covered within 10 km. along the Ganga banks, has low level arsenic contamination at present.

In Bhagalpur district most affected areas are Kahalgaon, Pirpainti, Sabaur and Sultanganj. A detailed study has been presented on groundwater metal contents of Sahebgunj district in the state of Jharkhand, with special reference to arsenic. Both tubewell and well waters have been studied separately with greater emphasis on tubewell waters. Groundwaters of all the nine blocks of Sahebgunj district have been surveyed for iron, manganese, calcium, magnesium, copper and zinc in addition to arsenic. Groundwaters of three blocks of Sahebgunj, namely, Sahebgunj, Rajmahal and Udhawa have been found to be alarmingly contaminated with arsenic present at or above 10 ppb.

Rivers flowing through the coal fields of Jharkhand have been reported to carry arsenic responsible for arsenic poisoning in downstream areas of West Bengal. The coal fields of Bachara and Piprawar areas of Jharkhand have contaminated the waters of the Damodar and its tributary, the Safi. According to author, arsenic contamination arises mainly due to the dumping of waste from the coal mines along the river bed. Coals of the area mentioned contains sufficient amount of arsenic.

Arsenic upto 608 parts per billion (ppb) was detected against the permissible limit of 10 ppb in some villages of Kahalgaon block in Bhagalpur district in 2005. Work was carried out by Dr. Sunil Chaudhary of TM Bhagalpur University.

A detailed work was carried out by Dr. Ashok Ghosh, Professor-in-charge, department of environment and water management, A.N. College Patna, in the arsenic affected areas of Bihar State. He found that out of 27,061 hand pumps, 7,218 pumps tested had arsenic contaminated water greater than 10 ppb (26.67%). Highest arsenic value recorded was 1861 ppb. Study also revealed that 87% of the Trivalent arsenic was found in the groundwater of Bihar State.
The study by Bihar's Public Health and Engineering Department (PHED) reveals that the average arsenic content in drinking water in the 12 districts is 500 parts per billion (ppb). The state capital, Patna, is among the affected areas.

According to Dr. Ghosh, a total of 16 Bihar districts (57 blocks) are affected by high level of arsenic in the groundwater. Worst-affected districts are Bhojpur, Buxar, Vaishali, Bhagalpur, Samstipur, Khagaria, Katihar, Chapra, Munger and Dharbanga.

A very alarming recent finding by the research group is the detection of high arsenic content (more than 50 ppb) in the water of River Jaminia – flowing parallel to River Ganga in Bhagalpur district of Bihar.This river merges with Ganga and water from this river is being supplied to urban Bhagalpur without any treatment, alarmed Dr. Ghosh.

Alarmed by the severity of arsenic’s impact on human body in these villages, the team also collected samples of hair and nail of affected persons for detail medical examination to ascertain the level of damage, said Principal Investigators Dr. Ashok Kumar Ghosh and Nupur Bose of A.N. College Patna. The findings indicated that a wider area, including the fertile irrigational lands, was under the grip of arsenic.

According to another research report done by Mr. Dipanka Chakraborti in Semria Ojha Patti village in the Middle Ganga Plain, Bihar, where tube wells replaced dug wells about 20 years ago, analyses of the arsenic content of 206 tube wells (95% of the total) showed that 56.8% exceeded arsenic concentrations of 50 micro g/L, with 19.9% greater than 300 micro g/L, the concentration predicting overt arsenical skin lesions.
