In this study environmental impacts related to unscientific waste disposal are identified. An effort was driven for evaluating the effect about MSW on the surrounding environment and GW quality at Mathuradaspura, Jaipur, Rajasthan. These outcomes disclosed that the contamination carried through the MSW brought about substantial effect on ambient air characteristic and GW of the area, the leachate from MSW landfills can be a cause of contaminations.
Based upon the results, it can be concluded that MSW dumping ground at Mathuradaspura in Jaipur has influenced the groundwater and ambient air characteristics adversely. The concentrations regarding physicochemical criterion i.e., TDS, TH, EC, NO3, F, Na as well as Cl were on higher side. Similarly the sampling site was polluted through heavy metals i.e. Ni as well as Fe, however Pb as well as Cd are exceeding the acceptable limitation and according to BIS standard no any relaxation permitted. Therefore, within the proximity of dump-site, groundwater is observed being not desirable toward drinking as well as another domestic purpose. The ambient air characteristic surrounding the landfill area was also got polluted through greenhouse and methane gas emissions.
Landfill gas as well as leachate production are concernments toward the applications about waste discharge into the dump-sites; requisite measures are needed for the sake of minimizing negative environment impacts regarding solid waste within Jaipur. The present condition of landfill in the Jaipur does not meet out the desired MoEF (The Ministry of Environment and Forests) guidelines about taking precautions to safeguard the environment. The deteriorating financial structure of JMC as well as the management and the executive authorities that are accountable for management of dumping sites as well as landfill stand failed for arranging modified solid waste congregation as well as effective landfill functioning. The information acquired in the present research should make an emphasis on public officials for the importance of keeping vigil at the wastes input, that will likely escalate in time ahead owing to growing up of population.
Therefore, there is a need to bring about an efficient management program for the present open dump-site as well as the landfill to regulate the pollution caused to environment. The following provisions should be provided:
i) Rather than disposing the wastes in the environment, the treatment and recycling should be started on war footing. It includes segregation of waste at source, composting and waste-to-energy conversion to be implied.
ii) Stringent ordinance on segregation of waste, PPP models and public participation could be a great help.
iii) Segregation of recycled waste should be practiced. Paper, glass, metals, cardboard and plastics etc. are common recyclable materials.
iv) The methane gas can be collected and used as normal fuel.
v) The non-recyclable waste except biodegradable could be utilized for energy production by combustion process.
vi) The emission of GHG (Greenhouse gases) is a matter of concern sharing the global warming which causes uncertain climatic conditions. The GHG emission is considerably reduced by managing solid waste scientifically. Inside the landfill open burning should be discouraged.
(a) By reducing and reusing concept, the consumption can be decreased and unessential GHG emissions can be avoided.
(b) The GHG emissions can also be reduced by recycling of the waste.
(c) The rag pickers participate by reducing the solid waste by 15% and restrict from disposing in dumping yards.
(d) The paper waste collected by rag pickers for recycling saves a number of trees from being cut.
vii) Daily covers should be practiced on regular basis.
viii) Provide Storm Water Drains and impermeable cover at the landfill site to restrict the infiltration of rain water.
ix) Provide lining system at the base and walls of waste disposal area to prevent infiltration of leachate.
x) Establish leachate collection, treatment and gas venting system.
xi) Preventing run-off out of landfill area.
xii) Vegetation cover should be provided at the dump site.
xiii) Segregation of recycled waste should be practiced.
xiv) Discourage the industrial and hazardous waste disposal at landfill site.
