In order to stay abreast with the growing problem of wastewater disposal, there are more and more methods that have been developed to treat it. Nowadays, wastewater is never just dumped, not if it can be helped anyway. For as long as it is treatable, wastewater is continuously recycled. One of the more known ways of wastewater treatment is through remediation. Remediation is the treatment process that removes pollution or contaminants from groundwater through the use of microorganisms, or rather, the introduction of microorganisms into the water. There are multiple wastewater problems that have better effects with remediation than any other wastewater treatment method. Below, are just a few examples.

1. Iron and Steel Industries wastewater- The growing need for more iron and steel have given way to the production of more iron, steel and other metals. Part of the production of iron from iron ores need powerful reduction reactions in blast furnaces. The cooling waters that are used to cool the iron become contaminated with chemicals like cyanide and ammonia in the process. When coal is produced, water used to cool it down can also release toxic by-products into the water. When this water goes into the general water stream and left untreated, it may contaminate the water with many complex organic compounds known as polycyclic aromatic carbons or PAHS. PAHs can be dangerous, if left untreated, so remediation is definitely required for the waste from these industries.

2. Mines and quarries- Mines and quarries used to be found far away from residential areas, but these days, more and more people are living in mining towns. The wastewater that is accumulated from mining can come from the washing and grading processes that happen in the mines, or from rainwater raining down on exposed rock areas. Because of the exposure, the wastewater from these areas usually has traces of surfactants and haematite. Other dangerous chemicals that can be present include certain oils and hydraulic oils. Again, remediation is the easiest manner so that these contaminants are removed and the water in the area is made potable again.

3. Food industry waste- in the effort to keep the food that we eat toxic free, agricultural and food operations, in turn, get rid of a lot of wastewater. The wastewater from this industry have its own unique set of characteristics. This kind of wastewater may be biodegradable and non toxic but high amounts of biochemical oxygen demand and suspended solids are still present. Particulate matter and surfactants are other contaminants that have also been reported. A particular kind of remediation can successfully remove the contaminants from food industry wastewater.

Everywhere we are, we are somehow always at risk to being exposed or taking in wastewater. It is a benefit to us that wastewater techniques such as remediation have been refined and are continuously being perfected everyday!
