I. INTRODUCTION
Any material that is thrown away or discarded as useless and unwanted is considered as Solid Waste. Solid
Waste is considered to be a direct pollutant to various environmental factors while it also shows many indirect
or silent effects on the environment. Solid waste (SW) can be defined as the material that no longer has any
value to the person who is responsible for it and is not intended to be discharged through a pipe. It does not
normally include human excreta. It is generated by domestic, commercial, industrial, healthcare, agricultural and
mineral extraction activities and accumulates in streets and public places. The words ‘garbage,’ ‘trash,’ ‘refuses’
and ‘rubbish’ are used to refer to some forms of SW. The Solid Waste is being produced since our ancient times.
However, the components and severness of the waste is changing. The materials which were included solid
waste at those times were simple and many of them were biodegradable. Nowadays, due to the advancement in
the science and technology, the solid waste includes many hazardous, non-biodegradable, toxic materials. Hence
the problems due to solid waste are becoming more & more severe. This lead to the detailed study and
inventions in the processing of solid waste and their proper disposal. The choice of effective methods for solid
waste processing can be best decided only after the study of hazardous impacts of solid waste on life. The solid
waste disposal is a major problem in developing countries along with developed nations.
The principle sources of Solid Waste are:
1) Municipal Waste
2) Industrial and Commercial Waste
3) Building and Demolition Waste
Classification of Solid Waste according to sources:-
Municipal Solid Waste:-
It is the waste collected from the town or city. It is subdivided as:
1. Refuse
(i) Garbage [Example- highly decomposable food waste]
(ii) Rubbish[Ex.-Waste easily non-degradable like rubber, glass, metal etc.]
2. Trash [Bulky waste material which requires special handling, like electronic]
Hazardous Nature of Solid Waste:
The solid waste produces various hazardous effects on life as well as on environment. Some of the major effects
are as follows :
1) Disease spread
2) Mosquito development
3) Development of other vector species
4) Strong odor spread in entire area
5) Leachate formation
Abstract: The impact of rapid industrialization around the globe and unsafe waste management practices
have become increasingly significant within the last two decades as the disclosed number of un-engineered
facilities and contaminated sites steadily grow and the anticipated remediation costs increase. A new service
sector is emerging across the world in waste containment, soil remediation and environmental restoration.
The need to accomplish the tasks given in environmental restoration and waste management places a new
responsibility on the services of the environmental engineer. It requires collaboration between geotechnical
and environmental engineers. This paper deals with the detailed study of the impact of solid waste dumping
on the Geo-Environment. The case study done helps to actual visualization of the effects of the same!
Keywords: Industrialization, Remediation, Geo-Environment, Responsibility.

6) Gas formation
7) Infertility of soil
8) Destruction of local ecosystem.
Methods of Disposal:- There are various conventional methods of solid waste disposal. The hierarchy of
methods to be adopted is given. This hierarchy is based on environmental principles and implies that waste,
depending on its characteristics, should be handled by different methods. It is generally known that the
hierarchy has to be applied in a flexible way and it is only meant as a guideline to achieve the best
environmental solution in long term.
1. Open Dumping
2. Land filling
3. Incineration
4. Pulverization
5. Composting
6. Disposal into sea
Conventional Process of Dumping:- The dumping of solid waste can be made effective by implementing it in
the proper scientific and engineering manner. The process of dumping of solid waste is as follows:
1) Collection of Solid Waste:- The collection of solid waste is generally done at the various levels. The waste
producing in housings is collected at those local points. And from there the entire mass of waste is collected in
Municipal Waste. The aid of various instruments, vehicles is taken for the proper collection of solid waste.
Collection includes temporary storage, transfer to a collection vehicle.
2) Transportation:- The collected waste is transported to the disposal site. The care is taken while the
transportation of waste in order to avoid any mishap due to waste i.e. it is carried in closed container etc. The
vehicles like collection trucks, front loader, rear loader, side loader etc. are used for the transportation.
3) Dumping:- The actual process of dumping initiates with the selection of dumping site. Usually, the dumping
site is so selected that it should be away from human habitat. The wastelands, barren farms, stone quarries which
are not in use presently, wells etc. are considered as sites for the dumping of waste.
Before dumping, the waste is to be processed to reduce its hazards , also the energy can be recovered from the
waste and the part of waste can be recycled. However, in most of the cases, the waste is directly dumped without
any processing.
Geo- Environment:- As the solid waste is practically dumped in the soil, the most affected factors by the
hazardous impact of the solid waste is Geo- Environment. This Geo- Environmental impact deals with all the
factors in the environment which ultimately reflects on all living beings.
Components of Geo- Environment:- Basically, all the natural resources on earth are a part of Geo-
Environment. The major effect of solid waste dumping is observed in the following components:
1) Soil
2) Ground Water
3) Water bodies
4) Atmosphere
Inter-relationship between components:-
 The soil is media in which solid waste is dumped practically.
 Soil is media for the ground water flow also.
 The waste traces from dumped solid waste, mixes with the ground water flow.
 This groundwater somewhere ahead mixes with water body which contaminates the entire water body.
 The dumping of solid waste encourages the decomposition of organic waste which leads to formation
of gases like Methane etc. which are evolved in atmosphere, which in larger quantity may help the
problems like global warming.

Plastics 10%
Metals 8%
Glass 6%

 It also affects the surrounding ecosystem of dumping site as well as the path along which these waste
traces flow.
 During the rainy season, the surface runoff over the dumping site, also leads to the flow of waste traces
to the low lying aquatic body and pollution of soil at every places from where it flows due to
percolation of water.
Impact of Solid Waste Dumping on Geo-Environment
Leachate Containment:- Solid Waste dumping generates highly contaminated liquid called as Leachate. Past
practices in dumping site relied on the natural ability of soil to filter and absorb the pollutants. Some leachate
results directly from the moisture and decomposition of garbage and other putrescible material in the waste
material, but much of it may come from runoff or surface water that first infiltrates the field and percolates
downwards through the waste dumped.
If leachate then reaches and mixes with ground water and seeps out of the field into a nearby stream or lake,
significant environmental damage can occur. Generally as more water infiltrates and flows through the landfill,
more pollutants are leached.
Gas Formation:-
 50% of the municipal solid waste in the landfill site gets broken down by bacteria for energy.
 This is done by aerobic or anaerobic fermentation.
 The degradable organic matter gets broken down into a stabilized organic residue (or compost), and
water and carbon dioxide, the latter contributing to the composition of landfill gas.
 ·The waste quickly becoming anoxic due to the high oxygen demand for bacterial respiration in
sanitary landfills.
 Anaerobic fermentation of organic matter will take place if sufficient moisture is present.
 With complete absence of oxygen, true anaerobic microorganisms, including methanogens, become
established.
 ·Organic acids and hydrogen in the waste are then metabolized forming methane and carbon dioxide.
 If the methane migrates to areas of the landfill, which are operating under aerobic conditions, it may be
oxidized to CO2 by methanotrophic bacteria.
Change in characteristics of Soil:-
Dumping of solid waste leads to change in following properties of soil:
1) Odour
2) Water content
3) Permeability
4) Bearing capacity
5) Porosity
6) Degree of saturation
7) Alkalinity
8) pH
The above mentioned changes are adverse by agricultural point of view. This decreases the fertility of soil.
 Natural Micro-organisms habitat loss:-
Dumping of waste, destructs the habitat of some beneficial micro-organisms like bacteria due to change
in chemical environment. It can be observed by the odour coming from the soil after rain of water
sprinkled.
 Loss of Biodiversity:-
The growth of plants on dumping site or nearby dumping site is of only restricted type. Only few species
of plants are observed on such sites, which are susceptive to the dumped waste. No other plant species
can survive, the same effect can be observed in birds, animals and ground worms also.
 Bioaccumulation:-
The concentration of hazardous substances in the waste, through the available plants, increases up to the
top of food chain. It’s a very dangerous effect later on.
 Aesthetical Appearance:-
The dumping sites are always surrounded by the garbage, with scavenging animals and such unwanted
things along with the strong odour. This may lowered the aesthetical importance of land.
II. CASE STUDY
Location of site:-
The dumping site visited is “Bilaspur city” in Chhattisgarh.It is located in the Chhattisgarh western region in
Bilaspur District.. It is the second largest city in the state with a population of 3,30,106 . Being the headquarters
of Bilaspur District; it is located 111 kilometres north of the state capital Raipur. Bilaspur enjoys the status of
being the headquarters of the South East Central Railway, which comprises the Bilaspur, Nagpur and Raipur

86-90
Divisions. Bilaspur is known for its aromatic Doobraj rice, handloom, woven, colourful, and soft Kosa silk saris,
and for its rich, varied and colourful culture.
Bilaspur City is situated on the banks of the Arpa River, which originates from the high hills of the Maikal
Range in central India. The average elevation of the city is 262 metres above mean sea level. The city area
slopes toward the Arpa River and the general topography slopes from west to east.
Generation and Collection of Waste:-
 The average per capita generation of solid waste in Bilaspur was found to be ranging from300-400
grams per day based on the varied income levels.
 The waste generated from highincome groups was found to be in the order of 400 - 450 grams.
 Those from low incomegroups generated 200 - 250 grams/day/capita waste.
 On an average the per capitageneration of 350 grams/day/capita seems to be a realistic figure to
estimate the total wastegeneration from households.
 Mixed waste is stored in various containers like plastic bins, cartons, plastic carry bags etc.by
households.
 At source, segregation is hardly practiced, usually the waste is dumped inconcrete ring bins.
 About 60 percent of the population still resorts to open dumping.
 Domestic waste is thrown on the street/lane corner, in the surface drains and in thebackyard of the
house.
 In ward numbers 6, 8,19,20,21,22,24,25 door to door collection ofwaste is in practice.
Presently there are a number of open dump sites apart from a number of places where 8 m3
capacity dumper
placer and 4.5 m3
capacity dumper placer containers are placed.
Dumping Details:-
 ·The stone quarry was in use as municipal solid waste dumping site from 2011 – 2012, near about 20
months.
 The rate of disposal of waste during these months is 150T/day.
 ·The unit weight of solid waste is considered as 400-600 kg/m3
 It can be imagined, that what a tremendous volume of waste was dumped during a short period of 20
months.
Hazards on Geo-Environmental Surrounding:-
Leachate Formation:-
The leachate is observed to be generated due to the waste dumping which mixes to a small ‘Nala’ through which
it enters the Arpariver. Hence highly responsible for the pollution of Arpa river. However, the fact is , the same
water contaminated with leachate is used for agricultural watering. The leachate has a natural flow with ground
water due to elevation difference. It has got a full chance to mix with groundwater flow because of slope
towards the Arpa river.
Gas Formation:- The saturated water during rainy season exactly above the dumping site, shows the bubbles of
gases, indicating the formation of gases due to waste.
Biodiveristy Loss:- Only 3-4 species of plants can be observed. Especially, these are the plants which only
grow at highly polluted soil. There is a lack of a well balanced ecosystem.
Infertility of Soil:-The soil is of no use from agriculture point of view. It has loosen the fertility already.
Micro-organism habitat loss :-During rainy season, it is peculiarly observed that there is no standard smellof
soil, which usually comes due to reaction of micro-organisms on sprinkling of water. This indicates the
disturbance in regular life cycle of micro-organisms in soil
Components of Landfill Gas:-
Landfill gas, also known as LFG, is composed of the following:
50-60% methane (CH4)
30-40% carbon dioxide (CO2)
10% Nitrogen
The Clean Air Act states current EPA regulations, which require that many larger landfills collect and combust
the landfill gas. Instead of allowing landfill gas to enter the atmosphere, it can be collected preventing methane
from migrating into the atmosphere and contributing to local smog and global climate change. In order to
comply, companies may flare the gas, or install an appropriate system to use it. The latter turn’spollution into a
renewable cost-effective resource, with many financial benefits. However, regulations on the gaseous emissions
from landfill sites, particularly the hazardous components, are deficient.
Benefits of gas collection
Health:- Collecting and processing the gas prevents the variety of toxic gases from entering the atmosphere and
affecting the health of the local population. The air would be cleaner, and it also helps to reduce odours. For
details of the potential health effects of landfill gas.

86-90
Generating Power:- 300 cubic foot of landfill gas can be produced per minute (cfm) from 1 million tons of
municipal solid waste in a landfill site. If this gas is successfully collected, appropriate utilization could generate
7,000,000 kilowatt hours (kWh) per year. This is enough energy to power 700 homes for a year. This source of
power is also extremely reliable, as the landfills do generate the gas 24 hours a day, 7 days a week, and can do
for 10 years or more.
Local economy:- More money can be brought into the area by the selling the gas collected. More jobs can also
be created, as gas collection and utilization processes require designing and construction of appropriate systems,
and people to operate them. The costs of producing electricity from landfill gas are low and very competitive
with costs for other renewable resources. Revenue is provided covering the costs of the projects, so they can
even be competitive with non-renewable electricity sources.
III. Conclusion
The subject discussed in this paper and the case study done, clears the impact of solid waste dumping on Geo-
Environment. The effects are easily seen because of solid waste. But there are many more invisible effects of
improper solid waste dumping on life.Instead of only economic point of view, the environmental conservation
should be given the priority for such activities. As the problem is directly related with the life, the strict actions
to be taken for the same. If the things are done in proper engineering manner, the severness of the problem can
be reduced.
The uses of some geo-synthetic materials, the treatment to waste before dumping, are some ways to neutralize
the long term effects of waste. The rules made for such activities should be implemented strictly. The new
methods of dumping and treating waste are to be implemented. Such steps towards the dumping site
developments will definitely lead the welfare of human being by means of Environmental Conservation!
