“…Similarly, these samples were 15, 15 and 20 metres farthest away respectively from the cassava processing points. This result was similar to that of Akpan, Eyong & Isong (2017). The current study like the previous (Akpan, Eyong & Isong, 2017) showed that the nearer the sampling point to the point of discharge the more acidic the soil sampled.…”

Purpose: This study investigated the effects of cassava effluents on the soil physicochemical properties and water quality in Ibarapa Region Southwestern, Nigeria. Methodology: Three Cassava Processing Sites (CPSs) and Control Sites (CSs) of 5m by 5m quadrant and three wells of varying distances to the CPSs were randomly selected in each of the three local government areas in Ibarapa Region. In all, nine CPSs, nine CSs and nine wells (SPs) were sampled during the dry season. The soil and water samples collected were subjected to laboratory analysis for physicochemical and bacteriological characteristics. The spatial distribution of the CPSs was determined using GIS techniques and Nearest Neighbour Statistic. Findings: The results showed that the CPSs distribution was significantly dispersed. However, that distance to the cassava processing sites impacted on the concentration of parameters tested. Analysis of the soil properties showed that the pH values were higher at the CPSs, elevated values of heavy metals were also noticed and cyanide concentration. Analysis of water quality in some of the sampled wells showed that the water samples were mainly within the WHO permissible standard except higher values recorded for heavy metals in SP 2 and elevated cyanide in SPs 1, 2, 3, 4 and 8 which were in close proximity to the processing sites. Bacteriological analysis also revealed that only SP 2 had the presence of Coliform Escherichia coli. Unique Contribution to Theory, Practice and Policy: The findings alluded to the inherent danger in man’s defective interaction with the environment. Hence, the study to a great extent could trigger appropriate measures in soil, water and waste management by stakeholders. Such measure could include treatment of cassava effluents before being dumped in to the environment as well as treating water before being consumed. Governments through her agencies such as the NAFDAC and sanitary inspectors should monitor the activities of these gari, fufu, lafun and tapioca makers especially about the discharge of cassava effluents.

“…[3] reported an increase in the quantity of cassava produced in Nigeria in recent times due to many initiatives and support programmes. Therefore, an increase in waste production is also expected which may result in environmental pollution when it is not properly managed [16].Also, the establishment of cassava processing centres is an on-going process of the government in Nigeria [2]. Such centres have been sighted in Okpokwu Local Government area of Benue State.…”

The socio-economic impact of cassava wastewater on some communities in Okpokwu and Ohimini Local Government Areas of Benue State, Nigeria were investigated. These communities are known for high rate of garri production in the State.Twenty structural questionnaires were administered on 293 residents within the study area. A large number (>80%) of the respondents in the community affirmed that garri wastewater had an offensive odour, changed soil colour, attracted mosquitoes and inhibited plant growth. The study revealed that a large number of the processor may not possess an in-depth knowledge on the effect of the cassava wastewater on the human health and environment at large. Environmental sanitation agencies may carry out routine inspection of processing areas as well as educate the processors of the hazards associated cassava wastewater.

“…The solid wastes and effluents from cassava processing factories in rural and semi-urban area are usually disposed of without considering specific guidelines on waste disposal and treatment [6][7][8][9][10]. When these harmful substances are discharged into the environment untreated, they may leach into the soil, alter the physicochemical properties of the soil and groundwater resources [11][12][13], and ultimately constitute serious health risk to the hosting community which depend solely on groundwater mostly from hand-dug wells for domestic and industrial uses [14][15][16]5].…”

2D resistivity profiling and hydro-geochemical analyses were carried out to assess groundwater contamination. in and around the Cassava Processing Factory at Aarada, Ogbomoso, Southwestern Nigeria. The dipole-dipole profiling was conducted along eight traverses, trending NW-SE, using electrode spacing a = 5m and expansion factor n=1 to 4. The resistivity data were inverted using 2D inversion procedure to produce the 2D inverted resistivity sections beneath the traverses. Water samples were also taken from seven hand dug wells within and around the study area for physicochemical analyses to determine the pH, EC, TDS, and concentrations of cations and anions which included Fe2+, Zn2+, Na+, Pb2+, Cu2+, K+, NO3ˉ and CN-. The 2D inverted resistivity sections revealed that the study is characterized by relatively low resistive zones typical of contamination plumes beneath the traverses near the cassava processing factory and general dumpsite. The pH values range from 7.2 to 8.0 and indicate that the groundwater is basic. They are within the WHO (2011) recommended limits. The electrical conductivity (EC) and total dissolved solids (TDS) exceed the WHO limit in the wells close to the cassava processing factory and the dumpsite, indicating that the water is harmful to human health. The major indicators of groundwater contamination in the study area are the Fe2+ and NO3ˉ caused by percolation of the dumpsite leachate, and CN- caused by infiltration of the cassava effluent, into the aquifers. The level of contamination in the wells is closely related to proximity to the cassava processing factory and the dumpsite. The discharge of the effluents from the cassava processing factory contributes significantly to cyanide contamination of groundwater in the study area. Appropriate remediation measures should be taken to forestall further contamination of groundwater in the study area.
