C+Block+-+Wastewater

We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment.decaying organic matter and debris can use up the dissolved oxygen in a lake so fish and other aquatic biota cannot survive.
 * excessive nutrients, such as phosphorus and nitrogen including ammonia, can cause eutrophication, or over-fertilization of receiving waters, which can be toxic to aquatic organisms, promote excessive plant growth, reduce available oxygen, harm spawning grounds, alter habitat and lead to a decline in certain species
 * chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae and fish
 * bacteria, viruses and disease-causing pathogens can pollute beaches and contaminate shellfish populations, leading to restrictions on human recreation, drinking water consumption and shellfish consumption
