Dampak Aktivitas Ekonomi terhadap Pencemaran Kualitas Air

Studi Kasus: Sungai Deli, Kota Medan

Abstract

This research examines the impact of economic activities on water quality pollution of the Deli River in Silalas Village, West Medan Sub-district, Medan City. The Deli River, once the lifeblood of trade and commerce, is now severely degraded due to the discharge of various types of waste, including household garbage, small business waste and cottage industry waste, all of which contribute to the murky, pungent-smelling and waste-filled water condition. The absence of adequate sewage treatment systems makes the river a major dumping ground for economic actors. The impact of this pollution extends to public health, causing illnesses such as itching, skin infections, diarrhea, and fever due to the continued use of polluted river water for daily needs due to economic constraints. In addition, the river ecosystem is also disrupted, affecting fish populations and overall environmental sustainability. Despite efforts from the government and related agencies, uneven monitoring and education as well as the lack of waste management facilities show a lack of effectiveness in addressing this issue. Long-term solutions require synergy between the government, businesses, and citizens, through strict enforcement of regulations, improved waste management facilities, and continuous environmental education to restore the Deli River as a clean and healthy water resource.
