Currently, groundwater is largely becoming the main source of fresh water in most developing countries. However, various deleterious impacts resulting from anthropogenic activities beneath earth’s surface have significantly affected quality, as evidenced several areas endowed with mineral and hydrocarbon deposits, agricultural activities, industrial processes. The possible etiological may include cancer genetic aberrations which result toxic effects organic waterborne contaminants ingested by humans animals over time. motivation behind this study was to identify determine concentration profiles pollutants wells located along Kerio Valley basin near exploratory for hydrocarbons mining activities. Therefore, necessary unraveling level sampled borehole water, can then be extrapolated cover other boreholes within basin. carried out during dry season December 2022. samples were extracted using a solid phase extraction procedure characterized gas chromatograph interfaced mass selective detector. findings indicate that benzene derivatives mainly xylenes, 1,3,5-trimethylbenzene, 1-ethyl-3-methylbenzene, 1-methyl-2-propylpentylbenzene polycyclic aromatic such naphthalene, phenanthrene, fluoranthene, azulene, pyrene found sampled. Furthermore, long-chain present all varying concentrations. ranged 2.84 20.47 ppm. exhibited highest concentrations pollutants, giving 23.14 ppm, fluoranthene (18.54 ppm), phenanthrene (14.13 ppm) anthracene (11.06 ppm). According reported study, contaminated unsafe drinking. Most levels times higher than standards U.S. Environmental Protection Agency. it develop policy framework on assessment monitoring quality region propose urgent measures ensure clean supply benefit residents.

Abstract Soil is a non-renewable resource, providing majority of the world’s food and fiber while serving as vital carbon reservoir. However, health soil faces global threats from human activities, particularly widespread contamination by industrial chemicals. Existing physical, chemical, biological remediation approaches encounter challenges in preserving structure function throughout process, well addressing complexities on regional scale. Viable solutions encompass monitoring simulating processes, with focus utilizing big data to bridge micro-scale macro-scale processes. Additionally, reducing pollutant emissions paramount due significant associated removing contaminants once they have entered soil, coupled high economic costs remediation. Further, it imperative implement advanced technologies, such monitored natural attenuation, embrace holistic management that involve regulatory frameworks, indicators, safety platforms. Safeguarding enduring resilience soils necessitates blend interdisciplinary research, technological innovation, collaborative initiatives.

A quantitative and qualitative assessment using molecular markers derived from compound-specific indices for indicating groundwater impacted by petroleum spills in an oil field was recently undertaken demonstrated serious contamination, with both high total hydrocarbons (TPH) (3.68–7.32 mg/L) hazardous compounds the groundwater. source identified, analysis revealed a decreasing trend of fresh input, along advection increasing biodegradation potential at locations farther source. This confirmed via microbial biodegrading microorganisms diversity (Shannon, Simpson, Pielou) principal component (PCA) modeling approach, which classified samples into three types according to distribution correlations between different organic compounds. Biodegradation believed be dominant sink due Pr/C17 Ph/C18 values seasonal changes. Raised temperatures activated degradation process; specifically, low-weight degraded more rapidly than high-weight hydrocarbons, resulting accumulation unresolved complex mixture bioproducts that were away. Spatially, increased upstream downstream areas, showing substantial biodegradation. The relationships chemical quantified canonical correlation (CCA) visually explain interactive reaction processes. It also organics can characterized consumption dissolved oxygen Pr/Ph ratio, system reduction. These results demonstrate markers, coupled biochemical parameters, effectively support better understanding effective fingerprinting fate transport contaminants, thus offering valuable technical cost-effective remediation strategy.
