Question

list some causes of untreated waste (any 10)

Answer 1

the effects of sewage on the environment are largely negative. It needs to be properly treated before it can be disposed of – usually into the ocean. There are two problems, however. If sewage is only partially treated before it is disposed of, it can contaminate water and harm huge amounts of wildlife.

Alternatively, leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. The consequences aren’t great. In September, a large part of the River Trent was polluted by sewage in Staffordshire. Over 15,000 fish were killed, and it would have been worse if the sewage had reached a human water source. Contamination of water sources can cause diseases to spread, such as e-coli, diarrhea and hepatitis A.

Even properly treated sewage can have its problems. Researchers have recently found that microscopic plastic fibres, released when certain clothes are washed, can make it through wastewater treatment plants and into marine ecology systems. Like the more common contaminants, they can harm animals and damage the food chain.
