Environmental baseline studies are integral to Environmental Impact Assessments (EIA), providing critical data on existing environmental conditions prior to project initiation. This study evaluates the environmental conditions at the Sustainable Procurement, Environmental and Social Standards Centre of Excellence (SPESSE-CE) Complex, Gubi Campus, ATBU, with the aim of establishing baseline data to guide future development and environmental management efforts. The assessment covers soil quality, water quality, air quality, noise levels, and radiation levels, reflecting the institution's commitment to sustainable development and evidence-based decision-making. Water analyses indicated consistent physical and chemical properties across multiple samples, with pH values around 7.3, temperature averaging 29.2°C, and electrical conductivity at 15.78 μS. Dissolved oxygen levels were approximately 19.3%, and key chemical indicators such as sulphate, chloride, and magnesium were within acceptable ranges. Soil analyses revealed a stable pH of 6.6, low moisture content at 2.25%, and organic carbon at 0.01%. Essential nutrients and potential contaminants were within safe limits. Air quality measurements showed indoor and outdoor conditions with PM2.5 and PM10 levels at 10.28 μg/m³ and 13 μg/m³ respectively, indicating low pollution levels. Noise and radiation levels were also assessed, with noise levels during non-working hours averaging 33.4 dB indoors and 34.5 dB outdoors, and radiation levels being very low. The findings highlight the importance of detailed baseline studies in environmental management, ensuring that potential impacts on water, soil, air, and overall environmental quality are comprehensively understood and monitored. This baseline data is crucial for the ongoing evaluation and mitigation of environmental impacts, aligning with best practices for sustainable development and environmental stewardship.
