3.1 Literature investigation
FlowMap is a freeware application proposed to examine and show stream data. This application was made at the Faculty of Geographical Sciences of the Utrecht University in the Netherlands.
b) GMT Mapping Tools
GMT is a free, open space aggregation of ~60 UNIX contraptions that empower customers to control (x,y) and (x,y,z) instructive accumulations (checking isolating, design fitting, gridding, envisioning, etc.) and produce Encapsulated PostScript File (EPS) portrayals stretching out from essential x-y plots through shape maps to erroneously lit up surfaces and 3-D perspective finds in high difference, diminish tone, hachure structures.
Geographic Resources Analysis Support System (GRASS) is the open space GIS programming application at first made by the US Government. GRASS is likely the most striking open source and special GIS programming applications. GRASS is a raster-based GIS, vector GIS, picture dealing with structure, outlines age system, data the official’s structure, and spatial showing system. GRASS can be downloaded in vain.
gvSIG is an open source GIS application written in Java.
e) MapWindow GIS
MapWindow GIS is open source GIS application that can be connected through modules. The application is fabricated using Microsoft’s .NET
OpenJUMP GIS is an open source GIS written in Java through a network effort by volunteers. In the past known as JUMP GIS, the application can examine shape records and GML association archives.
QGIS is an Open Source Geographic Information System (GIS) and is one of the more notable and use neighborly open source GIS packs available.
2.1 Stack Emission Parameters
The Stack Emissions were analyzed with the going with parameters: Destructive Mist,Smelling salts, Polyaromatic Hydrocarbons (Particulate), Suspended Particulate Matter , Sulfur Dioxide ,Benzene ,Xylene, Temperamental Organic Compounds (U OCs)
2.2 Ambient Air Quality Parameters the Ambient Air Quality was analyzed with the going with parameters:
1. Sulfur Dioxide (SO2)
2. Nitrogen Dioxide (NO2)
3. Ozone (O3)
6. Lead (Pb)
7. Carbon Monoxide (CO)
8. Smelling salts (NH3)
9. Benzene (C6H6)
2.3 Water/Waste Water Parameters The Water/Waste Water was analyzed with the going with parameters:
a. Recognizable Surface Water bodies, for instance, outfalls of CETPs, ETPs, treated exuding waste, conduit, channel, lakes, lakes and other such water supply resources coursing through the domain or spilling circumscribing the CPA.
b. Ground Water Quality data of obvious ground water resources, for instance, observation wells of Central Ground Water Board, drinking water wells, hand siphons, bore wells, hand siphons, bore wells and other such water supply resources arranged in the mechanical gathering/an area under idea or in the periphery zones.
Essential water quality parameters for surface water and ground water both are according to the accompanying:
I. Fundamental Parameters:
1. Clean Survey
2. Outward introduction Severely Polluted Areas: Monitoring, reviewing, assessment of Stack, Surface Water, Wastewater
6. Ecological (Presence of animals like fish, dreadful little creatures) (Applicable to simply surface water)
ii. Ordinary Monitoring Parameters:
9. Suspended Solids
10. Separated Oxygen (% drenching) (Not important for ground waters)
11. Creation Oxygen Demand
16. (NO2 + NO3)
17. Free Ammonia
18. Complete Residual Chlorine
22. Separated Phosphate
23. Sodium Absorption Ratio (SAR)
24. Complete Coliforms (MPN/100 ml) Severely Polluted Areas
25. Fecal Coliforms (MPN/100 ml)
iii. One of a kind Parameters:
26. Complete Phosphorous
27. Complete Kjeldahl Nitrogen(TKN)
28. Complete Ammonia (NH4 +NH3)
30. Surface Active Agents
31. Organo Chlorine Pesticides
32. Polynuclear fragrant hydrocarbons (PAH)
2.3 Methodology followed in Sampling and Analysis
Ventures, spots and regions that have been chosen for the examining are illustrative of the city/locale. Testing has been done at the potential tainted districts so as to arrive at the CEPI. This will advance help the specialists to screen the domains to improve the back and forth movement status of their common fragments, for instance, air and water quality data, organic damage and visual environmental conditions. Approach for looking at, protecting and assessment have been done by the references joined.
Based on the study done, the results are summarized and concluded as Six industries from Mahul were selected for Stack emission monitoring. Out the 6 stacks; Particulate matter was collected only from 5 stacks. All the results obtained are within the standard emission for the specified industry. NO2 was sampled from 6 stacks. The higher concentration of NO2 was observed at Tata Power with 62 mg/Nm3 . Six ambient air samples were collected from Chembur region. The parameters monitored were studied as per the NAAQ standards. The variations of each parameter within the area under study are discussed below. All the locations are observed with very low concentrations of SO2, with 3 stacks out of the 6 showed results below the detection limit. The highest level of SO2 was observed at Bharat Petroleum Corporation Ltd. with 4.76 µg/m3 which is very much lower than the standard limit of NAAQS i.e. 80 µg/m3. Values of nitrogen dioxide are also observed below the standard limit of 80 µg/m3 at all the 6 locations. The highest level of NO2 was observed at Bharat Petroleum Corporation Ltd. with a result of 67.6 µg/m3. 3 sampled locations in Chembur region showed higher level of PM10 concentration than the standard limit of NAAQS. The level of PM10 was higher at Tata Power, Aegis Logistics and Sea Lord with 103 µg/m3, 263 µg/m3 and 140 µg/m3 respectively.
