There are many different types of potentially detrimental affects that waste water can have on the environment. One of the many concerns that government has to deal with is the dangers that exist of waste water affecting the fish populations. While the water in most regions goes to the treatment plants to be treated some of the contaminants in the water are easier to destroy than others.
One of the problems that treatment plants are faced with are trying to get rid of certain types of chemicals. These are chemicals that can end up in the water as a result of detergents, soaps, and personal care products. It has to be realized that these are the contaminants that seem to put the fish at most risk if they are not effectively removed before the treated water is released back into the environment.
While human waste can be adequately dealt with in the treatment plants another major concern is industrial pollution. Again these are a variety of chemicals that are being added to the waste water and create extra challenges for the treatment plants to have to deal with as these changes can occur on an ongoing basis as new industries become present.
Aside from house waste and business waste other waste that has to be dealt with is the waste from the environment itself such as the runoffs that come into the drains in the city, for example. In those cities where the streets have been treated with salt and other chemicals this again is another contaminant that is entering the waste water and is one more chemical for the treatment plant to have to deal with.
If these contaminants are not handled properly they can have various effects on the environment such as being a toxic for wildlife and devastating for plant life. In rural areas it can affect the crop growth for farmers, and affect the foods that wild life need to sustain them.
