How does wastewater affect the environment?
Many pollutants present in wastewater can negatively affect ecosystems and human health: 1 Decaying organic matter and debris can use up dissolved oxygen so fish and other aquatic biota cannot survive. 2 High concentrations of nutrients (phosphorus and nitrogen) lead to over-fertilization of receiving waters. This causes huge algae blooms which reduces available oxygen, harms spawning grounds, alters habitat and leads to a decline in key species. Ammonia, a form of nitrogen, can be toxic to aquatic organisms. 3 Chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae and fish. 4 Bacteria, viruses and disease-causing pathogens can pollute beaches and contaminate shellfish populations, leading to restrictions on human recreation and shellfish consumption. 5 Metals, such as mercury, lead, cadmium, chromium and arsenic can have acute and chronic toxic effects on wildlife and human health.
