Storm Water Runoff
STORM WATER RUNOFF
Storm Water-Issues and Impacts
When rain falls, undeveloped areas are filled with the water, resulting in storm water
runoff on non-porous or impervious surfaces. Feldman, Foti and Montalto (2019) indicate that
storm water is a major environmental issue since it transports wastes and pollutants that pose
quality and quantity problems, affecting the quality of the environment and public health. In
urban areas, storm water causes nonpoint source pollution since it picks pollutants along its way
and deposits them in waterways. Contaminants in storm water may include heavy metals, oil,
grease, antifreeze, pesticides, chemicals, and sediment from poorly constructed areas (Feldman,
Foti & Montalto, 2019).
Uncontrolled storm water has effects on human beings and the environment because
polluted runoffs enter up in major water bodies such as rivers, oceans, and lakes. When rainwater
flows across an undeveloped surface, it picks up sediments that are carried to the water sources.
Accumulation of sediments reduces the clarity of the water, impedes the growth of aquatic
plants, and destroys aquatic habitats (Feldman, Foti & Montalto, 2019). Wastes and fertilizers
contained in storm water runoff end up in water sources causing algal blooms that are toxic to
aquatic life since they reduce the oxygen level for aquatic organisms. Animal and human waste
contains bacteria and pathogens in storm water. While animal wastes get into storm water
through surface runoff, failing sanitary sewers and poorly maintained septic tanks may contribute
to human wastes getting into storm water. Bacteria and pathogens that get into water sources are
public health problems since they cause illnesses and limit the recrea...
