This study investigates soil pollution in Orhangazi through two experiments. In the first, we planted green peppers in five pots with soil, watering them using various contaminated water sources: olive washing water, waste oil, pickle wastewater, chemicals, and tap water. The growth results revealed detrimental effects of the contaminants, as many plants died shortly after being watered. The second experiment sampled soil from diverse locations, including industrial areas and cleaner environments, to assess the impact of local factories on soil quality. Results highlighted significant pollution concerns.
