A well is used as an autonomous source of water supply in a suburban area. Its performance allows the resource to be constantly updated in the mine. This, in turn, prevents the appearance of external odors in the water. But there are often cases when the owner of the site notices that the water has deteriorated in the well, an unpleasant smell emanates from it. You can deal with the problem on your own.
Causes of Bad Smell from Well Water
The presence of abrupt sharp amber from the well and its contents suggests that chemical or biological processes are taking place inside the mine. The causes of stench are:
- The decomposition of organic matter (algae) that has fallen into the aquatic environment of the source. Often, such processes begin in those wells that have not been used for a long time (1-2 years or more). In this case, the water will smell like rotten eggs (hydrogen sulfide). The decomposition of organic substances and their use by anaerobic microorganisms provoke the appearance of hydrogen sulfide vapor. In itself, such a liquid is not dangerous for a person. But drinking it is impossible because of the sickening smell.
- The presence of mechanical impurities. If debris, chips, sticks regularly get into the shaft of the hydraulic structure, there is an allegedly rotting aspen shield at the bottom of the source, this can provoke the appearance of external odors. The water stinks of a swamp or has an amber stagnant. By sight, the presence of debris in the water is easy to determine. Such a liquid will be cloudy, dirty at the fence.
- Oversaturation with iron or other metals. Here from the mine the source will smash with iron. In appearance, the liquid has a yellow or brown color. If there is contamination with manganese, the aquatic environment will be black.
- Chemical industrial effluents falling into the horizon. In this case, the smell of oil, rubber, and other chemicals comes from the well. The fluid in the source will foam.
You can determine the type and cause of contamination of the liquid in the source by its color and smell. But it would be worthwhile to conduct a full analysis of the collected water.
Effective Solutions
To cope with third-party specific amber, you need different methods that depend on the cause of the source pollution.
Hydrogen sulfide
If it seems that the water is rotten, it means that algae and other microorganisms capable of living without oxygen grow in it. Why this happens, there is no exact answer. Most likely, from the bottom there is a dense siltation. Or the productivity of the aquifer has decreased significantly. Mine volumes are not updated as fast as before.
Hydrogen sulfide is removed by primary mechanical cleaning of the walls of the mine from organic matter. To do this, you will have to completely pump water out of the hydraulic structure and treat the walls of the reinforced concrete rings with a special disinfectant solution (chlorine, whiteness, tableted preparations). Then the source is completely filled and pumped out again.
Regardless of the reasons, the smell of hydrogen sulfide from water from the well can be eliminated by the physical method - aeration, that is, the saturation of the liquid with oxygen. To do this, use pressureless degassers, through which the fluid is forcibly driven.
The smell of the swamp
If the water in the well smells like a swamp, the reason for this phenomenon is siltation of the filter bottom. To cope with the problem, you will have to completely pump out the liquid and replace the filter layers.To do this, lay down zeolite, flint gravel, shungite 15 cm each. It will also be useful to treat the walls of the well with a chlorine solution. It is applied to the entire surface of the rings from the inside and the source cover is closed for a day. Then everything is thoroughly brushed, washed off, and the remaining chlorinated water is pumped out. In a week, the taste in the aquatic environment will change for the better.
Another method of disinfecting a liquid is iodine solution. It actively destroys pathogenic flora, prevents the growth of microorganisms in the aquatic environment.
To prepare a solution for 1 liter of liquid, you need to take 3 drops of iodine. As a rule, no more than 3-5 liters of solution are required for one reinforced concrete ring. If there are 10 rings in the hydraulic structure, then you need to take 50 liters of water and 150 drops of iodine. The whole mixture is simply poured into the source and defended for 24 hours. Then the well can be used for its intended purpose.
The water treated with iodine is not suitable for irrigation. Therefore, it is better to clean the resource in this way in late summer, early autumn. Until spring, the source will be completely updated.
Mechanical impurities
To clear water from third-party garbage is as simple as possible. To do this, the entire volume of liquid must be pumped out and driven through high-quality filters. In parallel, it is worth inspecting the walls of the shaft for cracks. Perhaps sand or clay oozes through them, polluting the hydraulic structure. If any are found, they are sealed with bitumen mastic. The bottom is examined here and, if necessary, the filter layers are changed.
Chemical odors
If they are permanent, the well shaft should be deepened to another aquifer. Otherwise, drains from nearby industrial enterprises will ooze to a home source. To make a deepening, you need to invite specialists who conduct preliminary drilling. It may turn out that it will be very far to the next layer and you will have to drill a well.
Odor Prevention
So that the water source of an autonomous source does not emit unpleasant odors, it is important to regularly carry out a number of preventive measures and observe certain principles when digging a well:
- Before work on the installation of hydraulic structures, it is necessary to study the aquifer. This will help determine the quality of water on the layer on which digging will be carried out. In addition, a thorough diagnosis insures against getting into clay layers and quicksand.
- When arranging the source, it is important to get to the waterproof layer. Otherwise, the well will be silted up regularly, which will lead to the appearance of third-party amber.
- When installing reinforced concrete rings, they necessarily carry out high-quality sealing of joints. Otherwise, water from the top will ooze into the well.
- It is advisable to protect the top of the hydraulic structure from precipitation falling into it. If this is not done, atmospheric nitrates, acids and other harmful substances will be mixed with well water.
- Well owners are required to regularly clean and disinfect water. Do this at least once a year. It is also recommended to inspect the filter bottom and change it if necessary. When cleaning and disinfecting the walls, it is better to work in pairs and use a respirator. Too much depth, lack of oxygen plus hydrogen sulfide vapors dangerous effects on the human body. High risk of losing consciousness.
Timely care of the well, its proper operation insure against the appearance of external hazardous odors, which are many times more difficult to get rid of than to prevent.
