Background
and Goal of Study
The municipal Solid waste management is necessary for
developing country and it required research study to do Decision making in
managing the Waste of City and Make Collection points away from the Water
source. The wastes produce in the Wa,Ghana are
Wa produces approximately 20,000 tons of MSW annually, based
on 0.45 kg/capita generation rate.
• This amount of MSW is composed of metals, paper and
cardboard, organics (including food and wood wastes), plastics, textiles, inert
substances (sand and ashes), and waste electric and electronic equipment.
• About 13,400 tons (68%) of MSW is collected annually in
the town and over 80% of that collected using the communal container collection
system (see Figure 2) while the remaining is collected through house-to house
system.
This research has been done to make a Data base map of the
WA, Ghana to indicate the pollution Risk point on the Wa,Ghana map from which
following data will be extracted
1.
The Water borehole Distance from the Municipal
waste collection site ( MWSC)
2.
Municipal Solid Waste Collection Efficiency and
Ground Dumping.
Methodology
Data
Collection
The data collection for this study was carried out in Wa from
June to August 2013 for both MSWCS and drinking water collection sources (i.e.
boreholes and hand-dug wells) using a GPS receiver, GPSMAP 62sc, a product of
Garmin. The data were then transferred to ArcMap 10.1 (ArcGIS 10.1) software
with the aid of DNRGPS software.
Relevant attributes were recorded for the MSWCS and drinking
water collection sources using data collection sheets. Areas with open,
indiscriminate dumps were noted during field visits.
The water source critical distance from the MSMCS site was
set for classifying the Risk of Pollution then the Map is generated in the Arc GIS.
Results and
Discussions
1. Municipal Solid Waste Collection Efficiency
and Ground Dumping
The results of this analysis are shown in Figure 5. Out of
the 51 MSWCS mapped, 17 (about 34%) had containers and no ground dumping of
waste, 20 (39% approximately) had containers with ground dumping of waste, and
14 (nearly 27%) are without containers with ground dumping. Overall, about 67%
of MSWCS are experiencing ground dumping, which suggests poor MSWM.
2. Boreholes Potentially Violating the
Groundwater Protection Requirements of Government Law ( Borehole safe distance
from MSWCS i.e 30m)
This finding suggests that all the hand pump boreholes
mapped in this study met the minimum 30 meter requirement for siting boreholes
with respect to the MSWCS while for mechanized boreholes with minimum distance
of 100 meters, 15 outputs (24% of mechanized or 15% of total boreholes) were
generated which is located with 100 meters.
