The objective of this study was to evaluate comparatively the effects of different brands of corrugated roofing sheets on rainwater utilized within Awka metropolis. Different physicochemical parameters were assessed in the rain water harvested using established standard laboratory procedures. The rain water was harvested directly (control) and also collected after passing through the different brands of corrugated roofing sheets (samples). The results showed no appreciable effects on the physical appearance, observable odour, or taste of the water samples compared to the control sample. However, at 30 °C, there were minor changes in the pH. The amount of suspended solids (SS) in mg/100ml, total solids (TS), and total dissolved solids (TDS) found in each of the samples, including the control sample, did not vary. This showed that the corrugated roofing sheet has no significant effect on the SS, TS, and TDS of the rain water harvested within the study area. Iron, zinc, and chloride ions followed a similar trend as SS, with Fe and Zn occurring at non-detectable limits of the instrumentation, while the levels of Cl-ion (3mg/100ml) did not vary in all the samples, including the control sample. The results revealed that corrugated roofing sheets affect the total alkalinity and methyl orange alkalinity of the harvested rain water in the study area greatly but had no impact on their physical appearance.

This comprehensive study delves into the analysis of Total Petroleum Hydrocarbon (TPH) concentrations in soot-contaminated rain and rivers within Oyigbo, Rivers State, Niger Delta, Nigeria, with a primary focus on unraveling the geospatial variability and distribution of TPH in the impacted water sources. The study adopts a multifaceted methodology, incorporating fieldwork, sampling, laboratory analysis, and geospatial mapping using ArcGIS 10.4 software to elucidate spatial variations. Results spotlight the highest rainwater TPH concentrations at MKT 7 - Umuosi Market (128.179 mg/L) and the lowest at SET 13 - Okpontu Settlements (8.976 mg/L), situated in the Okoloma and Umu Agbai-Obete axis, respectively. Likewise, river water exhibits the highest TPH at RVR 5 - Imo River (37.118 mg/L), and the lowest at RVR 6 - Imo River (187.118 mg/L), at Okoloma and Umu Agbai-Obete axis. Analysis of the 41 samples indicates that 19 locations surpass the 50 mg/L acceptable limits set by the World Health Organization (WHO, 2017), and the Department of Petroleum Resources (DRP - EGASPIN, 2018), Nigeria standards, with 10 locations recording concentrations above, and 12 locations falling below 30 mg/L. These findings underscore approximately 46% exhibiting high, 24% displaying medium, and 29 % showcasing low concentrations across the study area, following a spatial pattern with higher pollution dispersion in the Northern and North-western regions at Okoloma and Obigbo axes, and lower pollution levels in the Eastern regions at Umu Agbai-Obete axis. In essence, this study provides a comprehensive insight into TPH in soot-contaminated water resources in Oyigbo, contributing significantly to the advancement of knowledge regarding spatial variation, distribution, and implications for water quality management. Furthermore, it serves as a valuable resource for policy development, offering evidence for targeted environmental programs and practical assistance to environmentalists, researchers, government agencies, and the public in the assessment and enhancement of water quality in affected communities.

Assessment of physicochemical and microbiological characteristics of rainwater harvested from different rooftops in Owerri, Imo State was carried out using standard methods. Rainwater samples collected from different rooftops were analyzed for quality and compared to the standard for World Health Organization (WHO) and the National Standard for Drinking Water Quality (NSDWQ). Rainwater was also collected directly from the rainfall and analyzed. The result of the physicochemical parameters showed that only the rainwater harvested from asbestos rooftop had the pH value that falls within WHO standard and NSDWQ. The turbidity value of rainwater harvested from the thatched rooftop was higher than the WHO standard and NSDWQ. Organisms isolated from the rainwater samples harvested from the rooftops include Pseudomonas aeruginosa, Escherichia coli, Klebsilla pneumonia, Entrobacter sp., Proteus mirabilis, Aspergillus sp., Penicillum sp., and Vibro sp. However, after molecular studies, K. pneumoniae, P. aeroginosa, E. coli, and P. mirabilis were the four bacterial species identified. The rainwater samples had high levels of microbial loads against WHO standard and NSDWQ. Rainwater sample from thatched rooftop had the highest total heterotrophic count (THC) but all the studied rainwater samples had THC higher than WHO standard and NSDWQ. The rainwater harvested directly from rainfall had low values for the physicochemical parameters and microbial loads considered in this study, when compared to the rainwater samples harvested from the rooftops. The bacterial and fungal isolates of rainwater samples from the rooftops have been associated with different diseases. There is a need to treat harvested rainwater properly before domestic or potable use. This study has assessed the physicochemical and microbiological characteristics of rainwater harvested from different rooftops in Owerri, Imo State, Nigeria.
