When and how is the analysis of water from the well

Where to do a well water test

Water quality analysis services are provided by both public and private organizations. Each federal district has accredited laboratories that have the authority to conduct such studies.

These include:

• sanitary and epidemiological stations;
• geological laboratories;
• laboratories in regional offices of Vodokanal;
• in organizations related to geological exploration;
• laboratories at research institutes;
• accredited laboratories of Rospotrebnadzor.

The price depends on the type of study. The analysis can be abbreviated, aimed at identifying a specific group of substances, or complex, including chemical and microbiological research.

When choosing a laboratory, you should be guided by two parameters, these are:

1. The location and remoteness of the organization - after all, the key to the reliability of the results is the speed of delivery of the sample to the laboratory.
2. A positive reputation is a guarantee of the quality of research. Copies of high school diplomas and certificates can be requested from the manager of the selected organization.

Having decided on the choice of laboratory, it remains only to agree with the employees on the day of delivery of the sample so that the analysis can be carried out as soon as possible.

How to take a sample?

It is possible to accurately check the quality of well water only if the sample is taken correctly:

1. Use a clean glass or plastic bottle with a capacity of at least 1.5 liters. With tight lid.
2. Do not use containers for sweet and alcoholic drinks.
3. Pour water carefully along the side of the container.
4. Label the bottle where the sample was taken, the date and type of source.
5. You can store the sample for no more than two days in the refrigerator.

In our laboratory you can order the analysis of well water. To do this, you need to contact us at the specified numbers. You can specify the cost of the test when ordering an analysis by phone.

Wells are not among the centralized sources of water supply. Therefore, the requirements of sanitary and epidemiological standards for water from wells differ from the requirements for ordinary tap water. The thing is that it is used by a relatively small number of people, so the associated risks are lower compared to centralized systems.

However, this does not mean that the water from the source does not pose potential threats to the consumer. The well is an open source and is poorly protected from the influence of the environment, and is not subject to systematic monitoring of water quality - a frequent case is also the error of technical services in the design of structures.

Laboratory "NORTEST" offers a comprehensive analysis of water from a well, including:

• Chemical analysis;
• Microbiological analysis;
• bacteriological analysis.

We carry out an independent study of water from a well in a laboratory. We take samples ourselves, leaving the place, we comply with the conditions of storage and transportation, ensuring the reliability of the data obtained.

Timely analysis in our laboratory will allow:

• Get objective and accurate information about the state of water;
• Determine the presence and ratio of hazardous substances;
• Receive a full report in the form approved by regulatory enactments, which will allow using the data when contacting public services;
• Evaluate the performance of existing filters and propose your own solutions based on many years of research experience in the field.

Our laboratory analyzes water from wells in Moscow, carrying out a comprehensive survey from any open source. It includes an assessment of the level of pollution, taking into account regulatory documents, as well as indicators that will determine the suitability of the liquid for drinking and use for household purposes.

What to do in case of bad results?

If the analyzes showed the presence of organic or chemical contaminants, it is necessary to treat the water.

The following work is being carried out:

• Mechanical cleaning of the well shaft. They pump out water and remove all dirt, plaque, mud and other layers from the walls. Change the bottom filter (stones and sandy backfill soaked with silt).
• Eliminate mine leaks. Detected cracks or holes are carefully sealed. This allows you to exclude the ingress of unwanted components from the soil.
• Wall disinfection.A chlorine solution is applied with a brush or roller.
• Water disinfection. Use bleach, which is collected in a bucket. Then they scoop up water and pour it back, mixing the liquid with bleach.
• Use of specialized water treatment compounds that are commercially available.
• Installation of filters that trap foreign components.

Usually they produce a full range of works, paying special attention to the most developed types of pollution.

Sampling for analysis

To take a sample from the source and determine the quality of the water, choose the off-season period. During the spring and autumn months, surface waters are the most polluted. If they have the opportunity to penetrate the mine, then they will definitely affect the composition.

To check the quality of water from a newly built well, water for analysis should be taken no earlier than 3-4 weeks after its commissioning.

Water control is carried out only after a 3-week period of operation of the hydraulic structure. During this period, the pollution of the mine, which arose during the construction work, will subside, and the water will be partially cleared.

To obtain reliable results from a well water test, it is important that the sample is taken correctly. To do this, you need to follow a number of simple rules:

To do this, you need to follow a number of simple rules:

1. The container for fluid intake should be made of transparent colorless glass or plastic. It can be a bottle of mineral or distilled water with a volume of 2 liters, or a glass two-liter bottle. It is unacceptable to use eggplants from sweet and low-alcohol drinks for these purposes, if they have not been previously washed without the use of detergents.
2. When taking water from a well with a bucket, try to let it go a little lower than usual. This decision is explained by the fact that closer to the surface, the water may turn out to be stagnant, and at the very bottom it may include impurities of silt. Therefore, the best option would be the "golden mean".
3. Before filling the dishes, they are rinsed with selected water. Well water is poured into the bottle in a thin stream so that it flows smoothly along the inner wall of the container. Non-pressure supply will prevent the saturation of water with oxygen from the air, thereby preventing the occurrence of chemical processes.
4. The bottle is filled with liquid up to the very neck so that an air lock does not form in the container. If you are using a plastic bottle, squeeze the sides of the container slightly before closing the cap tightly, squeezing out the air.
5. Water taken from the well should be delivered to the laboratory within the next 2-3 hours. The faster the liquid gets to the laboratory, the more reliable the results will be. If this is not possible, place the container on a shelf in the refrigerator - this will reduce the reaction rate.

The maximum shelf life of a sample is up to two days. Temperature fluctuations should be avoided during sample storage.

A reverse osmosis system equipped with a semi-permeable membrane or filters is able to purify water from iron in high concentrations without the use of chemical oxidants.

The aeration method has also proven itself well. It is carried out by introducing air into the water using a compressor that creates atmospheric pressure drops.To do this, the water in the well is sprayed with special installations by means of spouting or showering.

Removal of hydrogen sulfide from liquid

Hydrogen sulfide is a waste product of anaerobic bacteria. Sulfuric bacteria live at the bottom of the well, where oxygen does not enter.

Experts offer two ways to solve the problem:

1. Physical
   - assumes saturation of the liquid with air. Forced aeration helps to destroy sulfur bacteria and additionally oxygenate the water, making it more beneficial to health. To implement this method, you will have to purchase expensive equipment.
2. Chemical
   - involves the use of disinfectants and oxidizing agents: sodium hydrochloride, hydrogen peroxide or ozone. It provides the most complete degassing. Under the action of oxidizing agents, hydrogen sulfide compounds are converted into less active forms.

The liquid, which has undergone chemical cleaning, must undergo additional filtration through active carbon. For water purification, both carbon filters equipped with activated carbon and filters with granular filler are used.

Treatment of water with a solution of potassium permanganate helps to eliminate the problem. Potassium permanganate powder is first diluted in a three-liter jar to obtain a concentrated solution of a saturated purple color, and then poured into a well.

In the future, in order to prevent the formation of colonies of bacteria that produce hydrogen sulfide, it is recommended to periodically “purge” with compressed air.

How often is the analysis done?

Depending on the area, it is recommended to carry out surveys at least once a year. In some cases, for example, in open reservoirs, samples are taken for analysis up to 4 times a year.It all depends on the problems identified earlier, the complaints of the population. After all, an unpleasant odor, sediment, poor appearance of water indicate pollution even without chemical and morphological studies.

If you are not satisfied with the quality of the water at the site (when there is no centralized water supply), you just need to find out how much the analysis costs and, if necessary, order it. So you will know what the problem is - in bad pipes of the plumbing systems in the house or in the well itself. With a qualitatively performed chemical analysis, specialists will find the cause. In most cases, the use of metal pipes for casing wells leads to an increased iron content (this will be shown by the analysis). In recent years, standard well casing has been carried out only with the use of durable plastic pipes (they can withstand rock pressure of 6 or more atmospheres).

As you know, water is the source of all life. It is the water resource that is considered the most demanded and in need of protection. Water helps to function not only for humans, but for our entire planet. Therefore, one of our most important tasks is to keep water sources clean, suitable for our needs and completely safe. To assess the state of water, we are accustomed to using the services independent laboratories for water analysis
. After the assessment, it is already possible to draw certain conclusions and develop a further plan of action.

Analysis of drinking water in Moscow, analysis of waste water in Moscow
- all this is necessary to consider how the source of water from which the sample was taken can be used.

Why else do you need make an analysis of drinking water in Moscow
? Our high pace of life, the development of industry, construction, manufacturing and other sectors of the economy, causes indelible damage to the environment. That is why it is necessary to ensure that the quality of the water is acceptable so that the water can be used safely. Laboratory wastewater analysis
allows you to solve the problem of choosing the necessary filters for water purification and determine for what purposes this water is generally suitable, that is, whether it can be drunk or used only for domestic tasks.

If you don't know where to take water for analysis in Moscow
, then you are lucky, you have already found the very organization involved in the analysis wastewater in a laboratory in Moscow
. The Moscow SES laboratory provides services to the population and companies for water analysis in Moscow, cost
which is not overpriced and will not hit your budget.

What is it needed for?

The analysis has at least 4 clear goals. If you conduct an examination once a year, you can be calm about the state of the water and your own health.

Why test your well water?

1. water quality will be assessed by objective, measurable parameters;
2. indicators that can be adjusted will be determined;
3. drinking water needs to be diagnosed, and only after a diagnosis is made, “treatment” can be prescribed to optimize its composition;
4. the installed filter system and other cleaning equipment will be assessed.

Usually, a potability test is required if the site with the well is newly acquired. It is definitely worth doing an analysis if the quality of water has changed: color, taste, smell. If a man-made emergency occurs relatively close to the well, the need for analysis is also obvious. When building an industrial facility nearby, expertise will also not be superfluous.

An analysis that is carried out once a year is an average norm. But the quality of water, alas, can literally change urgently. Anything can affect this: drought, chemical waste discharge, sewage ingress, etc. True, this may not always quickly affect the taste of water and color. We must remember about the norms of sanitary protection of the well.

The requirements for the quality of drinking water are established by the standards, spelled out point by point, and all of them will be a guideline during the analysis. The customer himself can request an analysis due to poor filtration (if it seems to him that the system is not coping and a different filter needs to be selected), if sand is found in the water, if its taste has changed, etc. But even without such “complaints”, the analysis can be a useful test.

It should be noted that the result of the analysis depends on the depth of the well.Surface water is called springs, the depth of which does not exceed 20 m - they are under direct external influence, they contain bacteria brought by rains and runoff. Examination will reveal nitrates, silt and traces of fertilizers in such material. Wells up to 5 m deep can be used only for technical needs, the analysis of minerals in such water will show a minimum amount.

Wells up to 30 m deep also have low salinity, but a lot of iron, chlorides and nitrogen - an extended analysis (chemical and bacteriological) is required. At a depth of 30 to 70 m, the amount of calcium and magnesium salts in the water increases (its hardness increases), as well as iron sulfates. Based on the results of the analysis, hydrogen sulfide bacteria can also be found.

Finally, wells 100 m deep or more are artesian. The water is filtered by gravel, sand and clay. This is the purest water. The analysis will reveal in it a minimum of phosphorus, nitrogen, hydrogen sulfide, natural bioimpurities and a high amount of metal salts.

Frequency and Periodicity

The frequency of trials depends, first of all, on the goals set. Before determining the frequency of sampling, it is necessary to process systematic data and a preliminary analysis of the available information regarding water quality.

Also, the frequency depends on the type and causes of changes in water quality, whether it is systemic or all changes in the composition of water are random. The only mandatory requirement for periodicity is in GOST 2761-84, which states that the frequency of samples should be fairly regular, and justified by systematic analysis.

Another determining factor is the type of water being studied, depending on where the sample is taken from and the results of its analysis, experts determine the frequency of sampling according to the technical documentation.

When determining the frequency, factors such as:

• The volume of water consumed.
• Cleaning and filtration methods.
• Number of users of water sources
• Results of primary research.

Why is water testing necessary?

For residents with centralized water supply systems, water quality expertise may be the only way to obtain adequate quality services from the water supply organization. But even if you live in a private house and water is supplied from an artesian well or well, microbiological examination of water indicators will allow you to draw conclusions about its suitability for drinking and domestic purposes.

But not always only tap water needs analysis. Sometimes the analysis of water from wastewater allows you to draw conclusions about the efficiency and serviceability of water treatment facilities. Also, the examination of bottled drinking and mineral water, which is regularly carried out at the manufacturer, will make it possible to draw conclusions about its compliance with regulatory requirements and quality.

It is often necessary to make an examination of water in order to choose a suitable treatment device or filter installation. There are many filter units, each of which performs its own functions. In order for water purification to be as efficient as possible, the choice of the unit should be based on the indicators of the treated water.

Why is water analysis necessary?

We have become accustomed to the fact that clean water comes in abundance and never runs out. To do this, the municipal authorities are doing a colossal job of cleaning up the huge amount of water that enters our homes.

Indeed, for example, thanks to chlorination, there are almost no bacteria and parasites in tap water. But bacteria are only a small part of the dangers hidden in the water we drink. Municipal water suppliers in the country have to contend with hundreds of potentially harmful substances that could cause irreparable damage to our health in the future.

However, it should be noted that the domestic water supply systems currently need a radical modernization. The water of 35-60% (depending on the region) of centralized water pipes does not meet sanitary requirements, since 70% of water pipes and distribution networks in Russia are in a dilapidated state and most of the public water supply systems require serious repairs, including the replacement of dilapidated distribution pipes. The cost of such work is high and the implementation of this project will take years.

Thus, now many residents do not trust the water that flows from taps. They also doubt the purity of water from drilled wells and dug wells in their country house. After all, it is possible that groundwater may be contaminated due to pre-existing unauthorized landfills, where waste disposal standards were not observed.

After all, despite the new restrictions, one of the main sources of groundwater contamination is still garbage dumps. Industrial waste and city sewerage continue to make their way into our waterways.Effluent from cesspools, sewage treatment systems, farmland - all this enters the water. Rain and snow further exacerbate this problem. Even radioactive waste enters the environment as a result of imperfect disposal processes or technology violations.

Water contains more than 75 thousand complex chemicals, and this number is growing daily due to industry, agriculture, etc. In small quantities, these substances enter drinking water every day, and no one knows what consequences this is fraught with.

But before looking for opportunities to improve the quality of a water source or an alternative source of water supply, they first do an analysis of their water. This is the only accurate and reliable way to check.

1. Water analysis allows you to find out its quality, make sure it is clean and suitable for drinking, washing, daily use, operation of household appliances and plumbing, or get disappointed and start changing the situation. One of the most reliable and effective ways to purify water is to install a filtration system.
2. It is for the calculation and selection of the configuration of the filtration system that water analysis is necessary.

What you need to know for self-sampling of water?

By following a few simple rules, you will be able to correctly select a test sample of water for research in the laboratory:

• The optimal capacity of glass or plastic containers for complex analysis is 1.5 - 2 liters;
• The container must be thoroughly rinsed with water from which the sample will be taken, without using cleaning agents and detergents;
• To prevent stagnant water from entering the container, it is necessary to pump water from the source within 10-15 minutes;
• Water is poured into the container in a thin stream along the wall to avoid saturation with atmospheric oxygen;
• The liquid must fill the container under the lid so that there is no air in it that distorts the test results.
• The most accurate result can be obtained provided that the time interval between sampling and its study is minimal (no more than 2-3 hours). If you do not fit within this period, then the sample should be placed in the refrigerator. In this case, its shelf life does not exceed 12 hours.

The sampling procedure for microbiological analysis is more complex. To carry it out, you need to take a sterile container from the laboratory.

The process of collecting water consists of the following operations:

• wash their hands with soap;
• without touching the neck of the bottle with your hands, remove the cotton-gauze stopper from it;
• the bottle is filled with water to the “shoulders”, closed with a rubber stopper (comes with a paper cap);
• the cap is fixed with an elastic band on the neck;
• the bottle is labeled, indicating the place, time and date of selection;
• the sample must be brought to the laboratory within 2 hours from the moment of filling (in the morning). If prompt delivery is not possible, the shelf life in the refrigerator is a maximum of 6 hours.

A complete picture, as we have already said, can only be given by a comprehensive water analysis conducted by the SES or in any laboratory accredited for such studies.

At home, this work can also be done, but for a limited number of indicators. To do this, you need to buy a special kit for express water analysis. It consists of special reagents and test colorimetric rulers. The examination procedure takes no more than 10 minutes and is accessible even to an unprepared person.

The test kit can determine the following parameters of water from a well or well:

• rigidity;
• pH;
• chromaticity;
• manganese;
• ammonium;
• common iron;
• fluorides;
• nitrates.

There are a number of portable photometers designed to assess water quality. Unfortunately, they are quite expensive (from 60,000 to 200,000 rubles), so they are used by laboratories for field analysis.
