Point source pollution
* When sewage is not properly collected and transported to sewage treatment plant in a sanitary way, sewage emanates foul odour causing air pollution and gives room for mosquito breeding leading to spread of diseases. * When sewage is discharged into river bodies without proper treatment, organic matters present in sewage causes depletion of dissolved oxygen which in turn affect aquatic eco system existing in the water bodies * Some gases like methane, carbon-di-oxide, sulphur-di-oxide, etc. are formed in sewage and escape into atmosphere causing air pollution and acclerating global warming by green house gases.
Environmental engineers design an construct waste water treatment systems. They organize later maintenance and upgrading. Environmental engineers working for regulators keep track f the performance.
Sometimes the only way to regain use of the aquifer is to treat the water at its point of use. For large water providers, this may mean installing costly treatment units consisting of special filters or evaporative towers called air strippers.

Specific answers can only deal with specific cases. In general pollution is dealt with by: * Identifying that the emission/problem is present * Stopping the emission at the source by process modifications or by adding treatment * Cleaning up accumulations of the pollution in the environment * Instituting monitoring program at the source and impacted area to monitorf future emissions Sometimes it is necessary to institute societal changes where pollution is seen as a "bad" thing that cannot be balanced by increased production or profit, or regarded as anatural result of industrialization.
Like the question "How long is apiece of string?" there is no answer for all gases. Pollution abatement at the source can involve the installation of millions of dollars with of treatment equipment or it can actually be profitable if the treatment recovers a waste stream that can be reused, resold or otherwise consumed. Similarly pollution which has escaped to the environment can cost millions or billions of dollars to clean up like the leaking oil platform in the Gulf or Mexico or be almost free if natural effects destroy the pollution by simply stopping the addition of fresh pollutants to the area.
Point source pollution
Point pollution control is environment management, and over the years this area of focus has implemented more than three methods of point pollution control. The more common methods are recycling, minimization of waste, and prevention. For each of these approaches, different control devices are used, such as, sewage treatment and dust collecting.

Water pollution can be controlled by the following measures: minimizing pollution generation, treatment of waste-water at the source, etc. In-situ pollution control measures like dredging, aeration of lakes and reservoirs, etc., can also be taken.
No, a control group does not receive the experimental treatment. It is used as a baseline to compare the effects of the treatment or intervention being tested in the experimental group.
