DUMPING RAW SEWAGE AND ITS RELATION TO OXYGEN/THERMAL POLLUTION
• Getting rid of untreated wastewater by dumping it into waterways, therefore contaminating the water
• Harms the environment
DUMPING RAW SEWAGE
• Wastewater– Contaminated water from residences, industries and commercial properties
• Sewage– Contaminated with human waste
– Disposed of using sewers and pipes
– Raw sewage is untreated
RAW SEWAGE
• Dumping raw sewage in rivers and other bodies of water contaminates the water and contains fecal matter, bacteria, viruses, parasites and toxic chemicals
• Sewage contaminates shellfish beds, drinking water supplies and aquatic wildlife and leads too the rapid growth of algae
HARMFUL EFFECTS
• Sewage takes away the oxygen found in water so fish and shellfish die– Oxygen is used by bacteria decomposing the sewage
HARMFUL EFFECTS
• Releasing heated water into a body of water resulting in the temperature of the water increasing– Puts aquatic life in peril, organisms are not adapted to the warmer temperatures
THERMAL POLLUTION
• Change in temperature in water can cause a decrease in oxygen levels
• Higher water temperatures can cause a boom in the algae population, which can also decrease oxygen levels for other aquatic life
