Indicators of water top quality. How to determine the standard of the water?
Chemical method of pure drinking water without H?O impurities. This is an best that is not found in character and in centralized water supply systems. Inside standing, running, properly water there are all sorts of suspensions and microelements, many of which are very dangerous to health, as they possess a storage capacity and also gradually poison your body.
Water quality indications allow you to determine its composition and appropriateness for certain purposes. To do this, you need to order a new water analysis from an independent chemical laboratory.
Laboratory analysis water from soil
The standard of water from a properly, a well, a natural reservoir depends on the landscape of the area and also the structure of aquifers. Carbon dioxide present in the soil enters the water tiers. Water saturated using carbon dioxide, following to the point of intake, dissolves mineral salts, including volatile organic compounds. This liquid becomes unsuitable for consuming and cooking.
Water absorbs everything that is in its path – lime green, chlorides, sulfates, nitrates and nitrites, pesticides. When it passes through rock salt beds, it mineralizes as well as becomes useful. Quite simply, the composition involving local water has to be studied. Residents of country houses should do the analysis not as soon as, but twice a year, as a result of possible changes in the nature of the soil.
Do you know the quality indicators
High quality is assessed simply by chemical and bacteriological make up, physical properties.
Chemical substance analysis consists within testing according to the following indicators:
hardness – is dependent upon the concentration of this mineral and calcium ions;
pH – indicates the activity regarding hydrogen ions;
oxidizability – shows the power of dissolved organic elements, determines the presence of wastewater;
mineralization is surely an indicator of the presence of mineral salts.
Research laboratory analysis for bacteriological indicators is carried out to identify the actual concentration of pathogenic and saprophytic microflora inside. The result is recorded which has a microbial number, demonstrating how many bacteria have been in 1 ml involving liquid. The microbe count in water from the mains supply can not exceed 100 cubic centimeters. Otherwise, it is undrinkable and unsuitable for cooking.
Actual physical indicators of high quality:
– Colour;
– transparency;
– flavor;
– smell.
What the examination will give
Laboratory evaluation allows you to assess it’s suitability for a particular function. Water quality indicators are specific markers for the content of chemical elements inside it, some of which are dangerous to human wellness. No less dangerous is the absence of other chemical compounds, without which the human body cannot fully perform.
The harmful microelements in the arrangement include:
– ammonia;
– nitrates and nitrites;
– chlorides;
– sulfates;
– hydrocarbons;
– fluorine;
– aluminum.
In normalized sums, such elements while magnesium, sodium, manganese, silicon, strontium should be present in h2o. To improve water good quality and disinfect it, companies add sodium hypochlorite along with polyphosphates to it. But the content of these substances has to be strictly regulated in order that their overestimated concentration does not harm people.
Water analysis ordered from an independent chemical substance laboratory will help guard yourself and your loved ones through serious chronic diseases.
