When it comes to testing water for the presence of chlorine, there are a couple of easy and straightforward ways in which you can do so. The ability to test water for the presence of sodium hypochlorite or chlorine is beneficial in a number of different ways.
The main reason it is so useful is because you have the ability to test to see exactly how strong the solution may be that you are using to disinfect the water in buildings. This is down to the fact that it is of a vital importance to know what the contact time and strength is in order to have a successful outcome.
Another great use is when you are unsure as to whether or not a water supply has been disinfected and you cannot take a chance or a gamble on this. This could be when you are abroad travelling or living in a caravan, you do not want to take any risks.
Otherwise you could be opening yourself up to all sorts of nasty bacteria that will lead to health issues even if you are not coming into direct contact with this water, simply breathing in the air around it can be enough for you to contract a disease.
For the most part if the test kit confirms that there is a trace of chlorine in the water then it is usually safe to assume that it has been treated appropriately and it will be safe.
If you do not find any trace of chlorine in the water then you should not take any risks when it comes to ingesting it. This is not to say that it is definitely unsafe as you can disinfect it by utilising tablets that rapidly release. The test itself is relatively inexpensive and you will be able to eradicate any doubts you have about the safety of a water source once and for all.
