Global statistics on polluted aqua paint a grim picture. Its estimated that fourteen thousand people die every day because of using adulterated aqua. In fact, it seems that the victims have to make a choice between dying of thirst or dying from disease. That shows just how much water contamination tests are needed.
Surface aqua, such as rivers and lakes, experience a different type of pollution from ground H20, the kind found in wells and boreholes. Surface aqua can be polluted by acid rain, run off from storm drains, poor waste disposal methods, such as raw sewage being dumped into rivers, and so on. Ground H20 is mostly polluted by surface precipitation leaching into underground sources.
Pollutants can be divided into two categories; point source and non point source. The former are those whose origins can be traced easily. These include sewage dumped into rivers, accidental oil spills, and so on. Non point source pollutants are those whose sources cannot be traced easily, if at all. For instance, sheets of aqua will sometimes wash away fertilizer or manure and carry it off to rivers.
The pollutants come in all shades and colors. There are those, such as plants and some man made chemicals that reduce the oxygen levels of an aqua source. This leads to the death of some forms of aquatic life. Others are disease causing bacteria, while some raise or lower the pH of aqua. Unnaturally raising or lowering temperatures is also a form of pollution.
Substances that raise or lower aqua's PH level are also considered pollutants. Raising or lowering the temperature of aqua beyond what is natural is also a form of pollution. All these are of great concern to anyone who needs clean aqua.
Those who get their aqua from local authorities can rest assured that it is consistently checked. The latest results are always made publicly available in some jurisdictions. For those who get theirs from private sources, investigative kits are widely available. Laboratory investigations can also be carried out for a small fee.
This check works even if the aqua is sediment. To determine the level of adulteration, different water contamination tests are carried out. One of these is the membrane filter technique. This involves passing aqua through a filter that traps bacteria. This is then incubated for twenty four hours, and the resulting colonies counted. If they are above a certain number, the H20 is considered polluted.
