“…The Event Mean Concentrations of TSS found in stormwater across the six landuse zones were higher than the maximum permissible loading approved by the WHO. These results are consistent with the findings of other scholars in this region such as [33] and [34], who also found high TSS concentrations in stormwater above the WHO permissible limits. This was the case because, there has scarcely been any deliberate effort to control stormwater pollution in Nigerian cities [20], and this is the primary justification for this study.…”

Purpose. Land use within a watershed affects surface water quality by creating a process by which diffuse pollutants such as suspended solids, trace metals, and nutrients enter rivers and streams. The purpose of this study is to assess pollution-load for Total Suspended Solids (TSS) and some trace metals in runoff samples collected during storm events in selected sub-catchment locations representing different land use areas in an urban watershed; and to determine the effects of land-use on the content of pollutants in stormwater using Event Mean Concentration (EMC). Results. There were high EMC and Site Mean Concentrations (SMC) of TSS in stormwater in the six land-use zones examined, with values ranging from 154.0 mg L−1 to 1464.0 mg L−1; and 216.5 mg L−1 to 1153.4 mg L−1 for EMC and SMC respectively. The total content of suspended solids was significantly high, above the acceptable threshold of 100.0 mg L−1 stipulated by the WHO. The researchers also found a statistically significant variation in TSS loading of stormwater from the commercial land-use areas compared with the other land-use zones. A strong correlation was also observed between the volume of stormwater discharged and the TSS load. However, the concentrations of trace metals in stormwater were low across the land use zones. The commercial districts of the studied cities were found to be major sources of suspended solids in stormwater, and pollution of the urban watersheds leading to the deterioration of the rivers. Scientific novelty. This study attempted to qauntify TSS load in stormwater and determine the contributions of the diffferent urban land-use areas to pollution yield.. It contributes to scientific efforts to directly quantify surface water pollution from nonpoint sources, since little attention has been paid to diffuse pollution, especially in sub-Saharan Africa; and provides baseline data for assessing urban stormwater in low-income countries. Practical value. This study offers guidelines for city authorities to develop land use policies to control surface water pollution and urban waste. The findings may also serve as emperical basis for greater advocacy by civil society organizations for the proper management and control of urban rivers and streams for public health benefits.

“…The mean values recorded across the three landuse types violated the permissible limit as set by WHO (2003). The three parameters (TS, TDS, and TSS) to a greater extent evaluate the quality of a drinking water, and their violation limits the aesthetic value of the water by increasing its turbidity which in a way becomes a public health issue (Mendie 2005;Ayeni et al 2006). Some studies have indicated high turbidity in urban areas (Pullanikkatil et al 2015) and in areas where sewage is discharged into waterways (Mendie 2005).…”

“…In recent years, there has been a rapid declining availability of usable fresh water in terms of water quality and quantity due to unsustainable landuse practices (Ngoye and Machiwa 2004). Water quality has variously been related to landuse in catchment (Levin 2012;Faiilagi 2015;Henderson et al 2014;Li et al 2008;Ayeni et al 2006;Pullanikkatil et al 2015;Wagner et al 2013;Olusola et al 2018), and studies have been focusing on their relationships with water quality variables such as dissolved salts, suspended solid, and nutrients (Mallin 2008;Mathuthu et al 1997;Elbag 2006;Keshtkar et al 2010;Olusola et al 2017). However, Pullanikkatil et al (2015) argued that there are correlations between systems of landuse and water quality, and emphasized the use of water quality index (WQI) in identifying pollution hot spots.…”

“…In most developing tropical countries, the use of surface water for domestic, industrial, and agricultural purposes is clearly evident and as such it calls for the need to carefully appraise the quality of surface water in order to ensure human satisfaction and well-being as well as maintain a safe and healthy environment. This becomes necessary as per capita water demand is increasing while the accessibility to drinking water is declining in Nigeria (Ayeni et al 2006). The knowledge will assist landuse management and improve landuse planning to control and palliate any adverse impacts on adequate provision of ecosystem services (Falkenmark et al 2009) which is very key to achieving sustainable development goals (SDG 15) (DeClerck et al 2016).…”

The study analyzed the impact of landuse types on surface water quality in an emerging urban city. The objectives were to classify the existing landuse types, examine the variation in water quality across different landuse types, examine the quality of surface water using the water quality index, and compare the water quality parameters with the World Health Organization (WHO) standards. Samples drawn from surface waters were analyzed based on in situ and ex situ analysis according to standard methods. Three landuse types were identified namely residential, vegetated and commercial. The vegetated landuse accounted for the highest landuse type with 74% of land coverage. One-way analysis of variance was used to determine the variation in water quality parameters within each landuse type. There was a significant variation in total solids (F = 8.677, P < 0.05), total dissolved solids (F = 7.836, P < 0.05), and total suspended solids (F = 10.365, P < 0.05). Using the water quality index calculator 1.0, a value of 41 was obtained thereby indicating poor quality. Water quality parameters were compared with World Health Organization (WHO) standards, and it was observed that electrical conductivity, nitrate, phosphate, sulfate, chloride were below WHO permissible limit while total dissolved solids, bacterial load and total solids were above the limit set by WHO. Therefore, there should be a continual intensive water quality monitoring program of surface waters across the area and its immediate environs to maintain healthy lifestyle of the populace and ensure ecosystem balance.

“…Understanding and monitoring surface water quality of a region remains a better tool towards promoting sustainable development of water resources within the societal economic and conservational contextual need [7]. Also of importance is the assessment of the human activities that are capable of changing the quality of river water within an urban area [8]. This is necessary, since per capital water demand is increasing while accessibility to available fresh water availability is one that decreases [9,10].…”
