The Path Taken For Drinking Water Testings

By Clarissa Osborn

Drinking water testings are a benefit to those who need to know about their water. H2O can be either clean or dirty. It is safe to make sure what levels of toxins are present in the water before being consumed. Dirty water can lead to a community being sick or possible deaths. The serious nature of the toxins in H2O can be sen in third world nations that have polluted sources.

The first step is to check on the bacteria and to make sure that the amount is not at unsafe levels. Good bacteria can be a precursor to bad bacteria being present in the sample. The sample must also be taken from a secure source. The tape must be clean and the well must not have extra pollutants from not being cleaned.

The microscope is used to test for bacteria and other debris in the water. Bacteria can be detected and must be kept at safe levels so that people don't get sick or die. The presence of other types of bacteria that aren't harmful can be the signs that something unsafe is starting to happen. Other harmful bacteria may be present with the other bacteria.

Debris is the next thing that needs to be checked. This is the material pollution that is in the source. This can be determined by having the microscope look at the amount per area in the slide. If the amount of debris at dangerous levels, then cleaning procedures will need to be done.

The sample is also tested for chemicals. Each chemical is tested and the levels are checked. There are several tests to check for these levels. One of the tests uses tester strips that can detect chemicals in the H2O. Each test will show the type of chemical and level that it is at.

The toxin levels in water can determine if an area is going to have to spend money to repair it. The idea is to keep the community healthy and this starts by having clean H2O and other items that are present. A clean source is an important one as it can change the environment because water is the source for everyone. Read more about: drinking water testings
