“…However, with increasing urbanization, more and more areas are covered with hard surfaces such as asphalt, increasing the amount of rainwater flowing into the sewer system. Rainwater collects contaminants from hard surfaces, such as car oils, street chemicals, and minerals, before entering the sewer system [ 1 , 2 ]. These substances can be harmful to the aquatic environment and pose a health risk.…”

Precipitation is an important factor that influences the quality of surface water in many regions of the world. The pollution of stormwater runoff from roads and parking lots is an understudied area in water quality research. Therefore, a comprehensive analysis of the physicochemical properties of rainwater flowing from parking lots was carried out, considering heavy metals and organic micropollutants. High concentrations of zinc were observed in rainwater, in addition to alkanes, e.g., tetradecane, hexadecane, octadecane, 2,6,10-trimethyldodecane, 2-methyldodecane; phenolic derivatives, such as 2,6-dimethoxyphenol and 2,4-di-tertbutylphenol; and compounds such as benzothiazole. To remove the contaminants present in rainwater, adsorption using silica carriers of the MCF (Mesostructured Cellular Foams) type was performed. Three groups of modified carriers were prepared, i.e., (1) SH (thiol), (2) NH2 (amino), and (3) NH2/SH (amine and thiol functional groups). The research problem, which is addressed in the presented article, is concerned with the silica carrier influence of the functional group on the adsorption efficiency of micropollutants. The study included an evaluation of the effects of adsorption dose and time on the efficiency of the contaminant removal process, as well as an analysis of adsorption isotherms and reaction kinetics. The colour adsorption from rainwater was 94–95% for MCF-NH2 and MCF-NH2/SH. Zinc adsorbance was at a level of 90% for MCF-NH2, and for MCF-NH2/SH, 52%. Studies have shown the high efficacy (100%) of MCF-NH2 in removing organic micropollutants, especially phenolic compounds and benzothiazole. On the other hand, octadecane was the least susceptible to adsorption in each case. It was found that the highest efficiency of removal of organic micropollutants and zinc ions was obtained through the use of functionalized silica NH2.

Water dams have been constructed in various regions across the globe to enhance access to potable water. Among these, the Aiba water reservoir, commissioned in 1957, was envisioned as a pivotal source of treated water for Iwo and its environs. Unfortunately, despite its inauguration, the primary objective of ensuring a sustainable and reliable water supply to the community remains unrealized to date. This research seeks to evaluate the accessibility of the study area to pipe-borne water (PBW) and discern the driving forces through the administration of structured questionnaire across 480 respondents out of which 458 were retrieved for analysis. The study utilized both descriptive and inferential statistics, employing Statistical Product for Service Solutions (SPSS) version 23. The respondent demographic revealed that 83.6% were female, and 18.4% claimed paying water tariffs while 76.2% relied on groundwater as their principal source of water. The data showed revealed diverse factors hindering PBW connectivity namely: Administrative bottlenecks (12%), while 57% cited the availability of alternative water sources as a reason for not connecting to PBW; 9% reported poor infrastructure for PBW, and 18% highlighted the unreliability of water supply from Aiba Water Works (AWW). Further analysis through Factor Analysis (FA) pinpointed three salient variables significantly influencing PBW accessibility. These are proximity to the main network (42.557%); cost of connectivity (22.275%); and availability of other sources (14.480%). These findings underscored the critical importance of expanding the PBW network, given the prevalent non-proximity of most residences to the main water pipes. Moreover, the research suggests that capacity building initiatives should be implemented to enhance the economic well-being of citizens, thereby fostering an improved quality of life for the inhabitants of the studied area. In conclusion, this study provides valuable insights into the complexities surrounding water accessibility and offers practical recommendations to realise SDG 6 by 2030. Graphical Abstract
