The inability of existing transfer stations in Greater Monrovia, Liberia, to handle municipal solid waste collected daily from designated collection points for temporary storage and final disposal has resulted in a number of issues such as abandonment of overfilled skip buckets and reinforced concrete bins, indiscriminate waste disposal into drainages, along roadside, river banks, and so on. This situation has also resulted in a number of negative consequences, including environmental degradation, public health concerns, depreciation of the value of adjacent properties, and decrease in the quality of life of the population. The local authorities have made relentless efforts to secure funding through its international partners to construct a well-designed municipal solid waste transfer station, However, due to the study area's topographic complexities, it is difficult for them to select an ideal site for a municipal solid waste transfer station to collect waste from designated and illegal collection points on time. To solve this issue, the research will analyze and identify potential sites while keeping the environment and population within the study area in mind. The research employs a comprehensive evaluation of multiple factors, including lithology, slope, drainage density and land use through GIS tool like Analytic Hierarchy Process (AHP) to identify potential sites that meets sustainable waste management’s requirements. The results showed that 43% of the study area is not suitable, 20% is least suitable, 20% is moderately suitable, 11% is suitable and 6% highly suitable for an environmentally-friendly transfer station. Central Monrovia A and B, and Northwest of Paynesville are areas identified to be suitable for municipal solid waste transfer station.

“…For instance, perennial floods have become common sight in slums of Accra during the rainy and often result in destruction of properties and sometimes loss of lives (Okyere et al., 2013). Such flooding has also been found to affect groundwater quality (Charles et al., 2020). In addition to these factors, we also hyposthesize that salt water intrusion is most likely to occur in slums that are located closer to the coast.…”

“…(2020) found groundwater in the Sebou Basin, Northwest Morocco to be of poor quality, while several other studies have found varying levels of heavy metal concentrations in groundwater of other cities in Nigeria (Ukah et al., 2020) and Ethiopia (Fito et al, 2019). Anukwonke (2014) for instance, noted that groundwater closer to dumpsites in Nigeria was of poor quality, with unaccceptable pH levels while flooding was found to significantly affect the groundwater quality of hand‐dug wells in Monrovia, Liberia (Charles et al., 2020).…”

A significant proportion of city dwellers in Ghana reside in slums where groundwater is the major source of water for domestic uses. This study examined the quality of groundwater from boreholes (seven) and hand‐dug wells (13) in five major slums in the city of Accra, Ghana. Water samples were tested for a total of 27 microbial and physicochemical contaminants at the central laboratory of the Ghana Water Company Limited. Overall, the water quality in the slums was poor as most of the parameters tested did not meet the 2017 WHO standards. Four out of the five slums (in Nima, Chorkor, Jamestown, and Abokobi‐Pantang), for instance, recorded high amounts of lead, with average values of 0.25 mg/L, 1.00 mg/L, 0.25 mg/L, and 1.5 mg/L, respectively, which are above the WHO standard of 0.01 mg/L. pH values in Nima (5.09), Sabon Zongo, Chorkor (6.09), and Abokobi‐Pantang (6.17) did not meet the WHO standard of 6.5–8.5. All five slums indicated various degrees of bacteriological contamination. The average Escherichia coli values per slum ranged between 12.50 CFU/100 ml and 249.00 CFU/100 ml, while the mean total coliform per slum ranged from 90.75 CFU/100 ml to 490.25 CFU/100 ml. The poor quality of groundwater found is attributable to improper disposal of waste, siting of boreholes/wells close to toilets, and the coastal location of some of the slums. Strict enforcement of water‐quality control checks, intensive sensitization on the dangers of improper waste disposal to groundwater quality, and the provision of sanitation facilities in the slums by city authorities are highly recommended.
