An Assessment of Air and Water Pollution Accrued from Stone Quarrying in Mukono District, Central Uganda

The unquenchable demand for rock materials has attracted many companies within the building and construction sector to invest in stone quarrying. However, this brought about environmental impacts with health threats people. There is a paucity of information magnitude pollution on air water how it varies quarry sites. This study, therefore, investigated physical quarrying explored in-situ mitigations undesirable effects due Four active sites were identified. Field measurements dust (particulate matter) conducted four nearby community. Water samples collected from pits shallow wells laboratory analysis quality. Statistical Analysis Variance (ANOVA) was used test differences across studied Results revealed that, amidst use wet crushing sprinkling bare surfaces, emission higher than recommended permissible standards levels significant variation ANOVA (P-value = 0.003) PM 2.5 0.04366) 10. mainly contributed by non-permissive nitrates, chromium, pH. Polluted are associated sparking off users In conclusion, should strengthen already existing mitigation suppression. study recommends additional measures such as treating pit before discharging open environment enhance protection against accumulating impacts.
