Check Health
79.00€
Human beings drink approximately 2 liters of water a day; a daily intake which provides our body with a large amount of mineral salts necessary for good health. However, if you suffer from certain diseases such as high blood pressure or renal colic, taking too much or too little mineral salts can be detrimental to your body.
Our water analysis, CHECK HEALTH, determines the physicochemical parameters which help us to know the salt concentration in water.

What parameters are included in the analysis?
BC
Bicarbonates 
Associated with the production of incrustation on water facilities.
Alkalinity in water is mainly due to the presence of carbonates, bicarbonates and hydroxides. It is a measure of the acid-neutralizing capacity of water. Acid-neutralizing capacity means the ability to accept acid without a subsequent drop in pH. The more acid that can be added to water before the pH starts to drop, the higher the alkalinity.
A minimum alkalinity of 20 mg/l is recommended since alkalinity concentrations below 20 mg/l often lead to large swings in pH values. High alkalinity levels are not detrimental to health; they may cause problems related to the existence of incrustations in equipments and pipes (see Hardness).
In the case of swimming pools, high alkalinity levels (>125 mg/l CaCO3) may cause turbidity or cloudiness of the pool water, create incrustations on the swimming pool walls and lead to an increase of the pH in water.

Ca
Calcium
Calcium is a cation and is a determinant of water hardness.
Calcium in water comes from natural deposits of limestone, dolomite, gypsum stones and gypsum slate.
Calcium is a determinant of total water hardness. To lower calcium and calcium hardness levels, chemical softening methods can be adopted, such as reverse osmosis, electrodialisis or ion exchange.
Low calcium carbonate levels avoid metal pipe corrosion since calcium carbonate promotes the formation of protective deposits. Some hardened and resistant incrustations are made up of calcium salts which leave behind precipitations on the surfaces of heat transfer such as boilers, pipes and kitchen utensils.
The concentration of calcium in natural mineral water should not be higher than 150 mg/l.

Cl
Chlorides
Chlorides reveal the presence of salts in water.
Chlorides in water are broadly related to saltwater intrusion problems, especially in most coastal areas. We get most of our supplies of chloride from the food we eat, mainly in the form of sodium chloride (salt); whereas chloride intake in drinking water tends to be less.
High chloride levels (> 250 mg/l) may impart a salty taste to water. Chloride concentration can lead to corrosion hazards.
Regulations recommend a maximum chloride concentration of 250 mg/l in drinking water.

D
Hardness
Water hardness is caused by the presence of dissolved minerals.
Hard water is high in dissolved minerals, both calcium and magnesium. Hard water can lead to taste problems and higher consumption of soap to produce lather.
Water hardness should be a concern since hardness greater than 20º F (200 mg/l CaCO3) may cause incrustations in water heaters, boilers, washing machines, irons, etc.
Water hardness lower than 10º F (100 mg/l CaCO3) may a have a low pH buffering capacity and, therefore, cause corrosion in pipes and materials in contact with water.

Mg
Magnesium
Magnesium is primarily responsible for water hardness.
Magnesium, (magnesium carbonate, magnesium sulphate), is an indispensable element abundant in the Earth’s crust. Together with calcium, magnesium is the most common source of water hardness. The degree of hardness becomes greater as the magnesium content increases.
There are no legal limits for magnesium in drinking water. However, high levels of magnesium (> 125 mg/L) may have laxative effects.
A level of 50 mg/L is recommended as the upper limit for mineral fresh water.

K
Potassium
Potassium is present in water.
Potassium occurs widely in nature and plays a key role in the human body. Average potassium concentrations in drinking water have beneficial health effects. Potassium may be used in drinking-water treatment plants (potassium permanganate, potassium chloride, etc.)
However, adverse effects may occur in certain segments of the population when consuming drinking water with high levels of potassium; including those who suffer from renal insufficiency, hypertension, diabetes, etc.
The WHO does not give specific guidelines on potassium levels since average potassium concentrations in water do not pose a risk to health.

RS
Total Dissolved Solids
(TDS) refers to a measure of the residual minerals dissolved in water.
Total dissolved solids measures all the dissolved substances which remain after evaporation or filtration of a water sample. These are primarily inorganic mineral salts and organic matter which originate in natural sources.
The WHO does not give specific guidelines on Total Dissolved Solid levels. However, elevated total dissolved solids can result in water having a bitter or salty taste and can cause incrustations in pipes, water heaters, boilers and electrical appliances.
Natural water can be classified by the amount of TDS per liter:
- Very low mineral content: up to 50 mg/l
- Low mineral content: up to 500 mg/l
- Medium mineral content: from 500 mg/l to 1500 mg/l
- High mineral content: more than 1500 mg/l

Na
Sodium
Sodium is largely related to water salinity.
Sodium occurs naturally and it related to other salts such as chlorides, sulphates, fluorides, etc. Water softeners (descalers) may increase sodium content of the water for human consumption.
Elevated levels of sodium may result in salty water taste and may cause high blood pressure.
The maximum acceptable level of sodium in drinking water is 200 mg/l.
Natural water can be classified by the amount of sodium per liter:
- Sodium water: more than 200 mg/l
- Water for children-food preparation and low-sodium diet: up to 20 mg/l
