Assessment of Water Supply Quality in Awka, Anambra State, Nigeria

Abstract

The patronage of water of questionable qualities in the study area

Hydrogeological and water quality evaluation of parts of River Mamu Sub-Basin, Southeastern Nigeria

“…Fine materials (Clay) and unconsolidated, non-plastic sand were major parts 4a and Table 1a). These results are conformable to those of Ezeabasli et al (2014) and Nwajinaka et al (2019). Ionic species are released from weathering processes, the dominant in the study area being weathering of silicates minerals, and dilution of NO 3 -, which has anthropogenic sources from domestic wastes and leachate from nitrate fertilisers (Omonona et al, 2017).…”

“…Another source could be from agricultural activities especially fertilizers and herbicides used in the farms and fishery. Previous studies in Imo Shale and Nanka Formation recorded high concentration of the trace elements especially iron (Okolo et al, 2018;Ezeabasli et al, 2014) hence, linking them to geology. The presence of these trace elements is a serious source of concern as the populace in the area drink the water directly without treatment.…”

Characterisation and performance of three Kenaf coagulation products under different operating conditions

“…Eight out of ten people in rural neighbourhoods in the sub-Saharan Africa region lack even essential water services, with the majority depending on surface water or unimproved water sources (WHO and UNICEF, 2017;WHO and UNICEF, 2019). Most surface water sources like rivers, streams and ponds are polluted and unfit for drinking due to natural and anthropogenic influences such as unregulated industrial discharges (Ezeabasili et al, 2014), climate change and the droughtinduced migration of livestock to water sources servicing rural populations (Bello, 2013).…”

“…Most of the polluted rivers, streams and ponds contain high concentrations of natural organic matter (NOM) including humic acid (HA), adding taste, odour and colour to them (Ezeabasili et al, 2014). The presence of NOM in drinking water makes water unpotable due to several hygiene and health reasons, with one of the most important being the formation of toxic chemical species during the disinfection process.…”

Predictive Model for Leachate Contamination of Groundwater around a municipal Waste Dump: Case Study of Obosi, Southeastern Nigeria

“…Many researchers have also carried out investigations on the state of groundwater within Anambra state. Most of these studies are limited to spot measurements used for baseline studies (Egboka et al 1983;Ezeabasili et al 2015;Ezeabasili et al 2014;Ogbukagu, 1986;etc). However, none of these studies proposed or used any simulation model capable of modeling leachate contamination pathways and dynamics.…”
