There’s no doubt that the water we use should be pure. Polluted water is the disseminator of many diseases, including hard ones (typhoid, dysentery, cholera, ankylostomiasis, etc.) that might cause irreparable damage to human health. Water is the main source of such human and animal vermin as a tapeworm or lamblia. Unfortunately, polluted water exists even in the economically developed countries that’s why it’s crucial to monitor the major indicators of drinking water quality.
Drinking water quality criteria is divided into the following metrics:
- Organoleptic features imply the chemical substances influencing smell, taste, and color of water.
- Toxicological properties point to water chemistry.
- Epidemic performance.
The State Standard 2874-82 regulates health standards for drinking water quality where the tolerable range of the chlorine after chlorination is pointed out, as well as ozone concentration and other meaningful indicators of drinking water quality.
Human senses are able to define such organoleptic or physical-organoleptic properties as smell, taste, aftertaste, color, degree of transparency, etc. These are the key factors of water hygiene and quality. The assessment of drinking water quality is carried out with the aid of a scale of 1 to 5. So, tap water’s quality corresponds to the State Standard 2874-82 and state health regulations and standards (SanReN) and it’s considered to be safe drinking water.
If edibility, smell, color, turbidity or transparency could be determined independently, such drinking water standards as the hydrogen ion exponent (pH), rigidity, mineralization, iron (Fe), copper (Cu), manganese (Mn), zink (Zn), and other chemicals’ levels could be reveal only when analyzing the indicators of drinking water quality in the designated laboratories or subject to the availability of the specialized instruments.
The most important indicator of drinking water quality is its correspondence to the epidemic regulations. In Ukraine, according to the valid State Standard 2874-82, the total amount of microorganisms and the bacterium E. coli define the epidemic norm. The majority of the enterprises producing bottled drinking water (TM Key of Health, for example) adhere to all the water quality guidelines.
In general, - it will take a long time to list all the indicators (more than 60!) that drinking water in Ukraine should be relevant to. However, one thing that we do know is that water quality has a direct impact on our health that’s why think a few times before drink tap water. Is it worth your health? We’re sure that our health is priceless, so, can’t be too careful when buying water in the nearest supermarket to ensure no danger to your health.
