An independent source on the site is the key to a comfortable stay in the house. More often, craftsmen prefer to drill a well or dig a well. With the correct execution of work, it is possible to achieve a relatively clean aquifer. The liquid from it visually seems suitable for drinking. But it also happens that the water from the well turns yellow in the air after its intake. There are several reasons for this. You need to fix the problem depending on the situation.
Causes of Yellowing Water
If the water from the well turns yellow after several hours from the moment of its rise or literally right away, the main role in this process is played by such factors:
- The presence of divalent (dissolved) iron in the liquid. In this state, the element is not visible to the human eye. But during oxidation (combining it with oxygen), it changes its structure to trivalent, precipitates and takes on a visible form. Particles of such iron can be filtered. The oxidation of Fe2 is inevitable during the rise of well water. If the liquid collected in the glass turns yellow over time, and small grains of iron settle to the bottom, then it is enriched with a chemical element.
- Corrosion casing. Here, iron (rust) is present in a liquid in a trivalent form and is immediately visible to a person.
- Water enriched with manganese. Here the same processes occur as in the enrichment of the resource with iron. Manganese water is unusable. In addition, a liquid mixed with Mn changes its color when boiling or heating. If this happened, it is about manganese.
- Admixture of clay or sand. If the bottom filter is defective or the casing is depressurized, a fine soil fraction oozes into it. Such impurities in the form of clay or sand change the color of the liquid to yellow. The intensity of the shade and turbidity depend on the concentration of dirt in the water.
- Humic acid or tannin. If a well is drilled on peaty soils, such impurities are not uncommon. The resource is unsuitable for consumption.
- Hydrogen sulfide. In this case, when boiling, the water is covered with a cloudy film and it smells extremely unpleasant even when it rises.
Poor pumping or filtering equipment can be an additional reason for the yellow tint of liquid.
The possibility of using yellow water
If the water from the well turns yellow when heated, boiled, or simply in the air, it is strictly forbidden to use it in food or drink. This threatens the following phenomena:
- food poisoning;
- disorders of the stool, vomiting;
- allergic reactions;
- bacterial poisoning.
For household appliances, the use of such a liquid threatens with the following:
- Failure of the working elements of a washing machine or dishwasher. This is due to the accumulation of a large sediment of sand, clay, iron on the internal parts of the equipment.
- Damage to the boiler and pipes of the heating system.
- Failure of pumping equipment that is not suitable for pumping contaminated products.
- Damage to filter systems in the house.
- Plumbing equipment malfunction over time.
If such water is used for irrigation, then under the influence of manganese, the plants will burn. Iron, sand and clay will not have the best effect on productivity and will significantly damage the fruits.
Washing laundry in contaminated water will result in yellowing of white items. Eliminating pigment is then extremely difficult.
It is allowed to use dirty yellow liquid from a well / well only for washing cars, household equipment or stoves in the yard.However, unsightly stains will still remind you that it is time to clean the borehole resource, apply at least some measures to eliminate the problem.
How to solve the problem
You can correct the situation if you find out the root cause that led to the formation of a yellow liquid.
Iron
If corrosion of the steel column is detected, it must be understaffed with an internal polymer pipe. It will have a smaller cross section, so you have to buy and install a submersible pump of a different diameter. But such costs completely neutralize the presence of iron in the water.
When it comes to enriching the Fe2 resource, you need to take care of a quality de-ironer filter. It has a special load inside, which contributes to the oxidation of particles of divalent impurities. Reduced to a different, balanced state, iron settles on the walls of the filter.
In order for the cleaning system to work properly, you need to regularly change the load and rinse the installation flask with running clean liquid.
Clay or sand
The casing should be examined for depressurization. If necessary, eliminate all problem points or install an inner plastic pipe.
For a clay bottom, it is advisable to install a bag-type filter. It well prevents the ingress of impurities into the mine.
For the sandy bottom you need to install a new strainer. It is advisable to change the backfill to fine-grained pebbles.
Hydrogen sulfide
To fix the problem, you need to clean the bottom of the source well, pump it, rinse it with a powerful pump and replace the bottom filling. Here you will have to install an aerator, which will enrich the liquid with oxygen. When it interacts with fetid gas molecules, the latter oxidize and evaporate into the air. If this is not done, such water can lead to pulmonary edema, paralysis, serious toxic poisoning.
Humic acid or tannin
A similar problem is typical for peaty soils. Therefore, when arranging the source bottom, you must first take care of a good backfill in the form of pebbles of different fractions. Lower levels are larger stones. The upper ones are smaller.
However, even pebble backfill does not insure against impurities of tannin or humic acid. Therefore, you need to take care of multi-stage resource filtering. One of the first layers of the treatment system should be a carbon cartridge. Behind him is the membrane.
It is recommended to put a reverse osmosis unit under the sink in the house to completely eliminate yellowness and any harmful impurities from the liquid.
Only high-quality water treatment leads to its normal state, regulated by sanitary standards. Drinking uncleaned is strictly prohibited.
