About chemical water composit ion ofthe well BQ-2 (Rogatets-Sobonki, the Czech Republic) and the possibility of its use for drinking purposes and for bottling as natural m ineral table water.
The conclusion has been drawn on the basis of the given data of chemical composition research and water propert ies of the we ll BQ-2 at the request of LLC “Svyatopramen” (Yubileini, Moscow region) for Bohemia Beverage Industry Group
- The analyses have been performed by Analytical laboratory of natural curative springs (Karlovy Vary, the Czech Republic ; laboratory complex analysis protocol No. RL 254- 12, 14th December, 20 12) and Department of health laboratories (Karlovy Vary, the Czech Republic; Public government decision of nuclear safety No. 9317/2004, 30th April, 2004; test protocol NQ 10478/2012, 10th December, 20 12)in accordance with the requirements of the normative and technical documentation of the Czech Republic- notification by Czech Ministry of Health No. 423/2001 Sb and usage of appropriate testing methods and (full chemical analysis). There have also been detected organ ic matter markers in RL (research laboratory) of FSBI «Pyatigorsk SSRI of Resort Study FMBA, Russia» (Pyatigorsk, accreditation certificate in the certificat ion system GOCT P N POCC RU.OOO 1.2l.DB.05, 15th October, 2009; protocol agreement NQ 1/0KP, ll th January, 2013).
Cold ground sweet water of the spring has been produced from artesian well BQ-2 (the depth is 82 meters, temperature 12.2°C, flow rate is 120 1/m in) in Rogatets Sobonki, the Czech Republic and can be used in hou sehold water purposes. As a production level the well has drawn out terrigenous depos its of pontian stage of low pliocene that were piled like terrigenou s deposits (clay, sand, compacted silt) with inclusions of brown coal facies (l ignite). Possible additional use of water is industrial bottli ng of potable natural mi neral table water in accordance with the normative and technical documentation.
Fractional organic composition analysis and qualifying estimation of chemical water composition have been catTied out in the physicochemical laboratory of mineral water and therapeutic mud of FSBI «Pyatigorsk SSRT of Resort Study of FMBA, Russia» (Test Center in the certification system GOCT P, accred itation certificate N POCC RU.OOO L .21.118.05, October 15th, 2009) in accordance with the requirements of NTD of the Russian Federation – GOCT P 543 16-2011 «Natural m i neral drinking water. Gcncral technica l conditions» , SanRegN 126.96.36.1998 01 “Hygiene requirement s for the quality and safety of raw materials and food products. Sanitary regulation s and norms” and usage oftest methods according to GOCT 23268.0-78- 23268.18-78 as well as SanRegN 188.8.131.524-01 “Drinking water. Hygienic requirements …”, GOCT P 52109-2003 “Bottled drinking water. “General technical conditions” and SanReg N 2. 1.4.1116-02 “Drinking water. Hygienic requirements for water quality in bottles …” and “General sanitary-and-epidemiological and hygienic requirements for goods subject to sanitary-epidemiological supervision (control)” – chapter II, article 9 “Requirements for drinking water in bottles”, article 21 “Mineral water requirements” (Customs commodity code: 2201 10). Analyses results are shown in the attached protocols and fonn. This resolution was prepared in March, 2013 based on the results of library materials processing and presented results of the water inspection from the given well.
According to the conducted studies the chemical composition of the water wells BQ- 2 (Rogatets-Sobonki, the Czech Republic) can be described by the following formula:
HCO3 96 (Cl 3 SO4 1)
M 0,29 ———————————— pH 8,0 T 12 oC,
(Na+K) 61 Ca 20 (Mg 16)
So it can be characterized as fresh (“sweet water ” or “oligominerale”), hydrocarbonate-calcium-sodium (almost magnesium-calcium-sodium) composition of alkalcscent med ium reaction. According to the thermal indication it belongs to the group of cold water.
The water of the spring taking into account its organoleptic properties is transparent colourless liquid with a weak hydrocarbon odour and tastes fresh; there is no sediment.
The composition of dissolved gases is characterized as nitrogen-methane; the content of dissolved free carbon dioxide (C02) is not more than 9 mg/I.
The tested water has no radioactivity: the contents of natural and anthropogenic radionuclides does not exceed their background values for natural underground mineral water set by fOCT P 54316-2011, SanRegN 184.108.40.2068-01 and radiation standards (RS) – 99/2009. Total alpha-radioactivity does not exceed 0.2 Bq/kg (0.036 ± 0.005 Bq/kg), total beta-radioactivity does not exceed 1.0 Bq/kg (0.081 ± 0.008 Bq/kg).
The content of other microelements including fluorine, arsenic, lithium, strontium, and barium, ions of heavy and non-ferrous metals does not reach the standards that characterize them as biologically active and does not exceed concentrations allowed by fOCT P 54316-2011, SanRegN 220.127.116.118-01 and “General sanitary-and epidemiological and hygicnic requirements for goods subject to sanitary epidemiological supervision (control)” – chapter II, article 21 “Mineral water requirements” (Customs commodity code: 2201 10).
The concentration of inorganic nitrogen compounds (nitrate, nitrite ions and ammonium ions) is in the normal range.
Total content of organic substances in the water of the spring is low and has 2.34 mgS/1 non-volatile organic compounds of carbon (pennanganate oxidation is 1.76 mg0/1) which is less than the established balneal norm for water to be treated as therapeutic table water (5 mg/1 < Corg.sub < 15 mg/l). Fractional composition was presented by humic substances, neutral and acidic bitumen (sum ofthe fractions is up to 4.0 mg/1). Nevertheless phcnols, aromatic hydrocarbons and other compounds in thc type content which are subject to prohibitive criterion haven ‘t been found.
We don’t have systematic library materials about the water of the spring and therefore the following classification criteria and recommendations are tentative and can be specified later with the accumulation of observation data for the chemical composit ion of natural water. The compar ison of the received analysis results with the long-term observations data of chemical composition of fresh water deposits in the North Caucasian Federal District of the Russian Federation proves the stability of macroion and microcomponent composition of underground water and its good quality.
Thus the tested water of the well BQ-2 (Rogatets-Sobonki, the Czech Republic) refers to mineral natural table water and is fresh hydrocarbon calcium-sodium (or magnesium-calcium-sodium) without specific components and properties (taking into consideration its min eralization and the main ion composit ion) according to fOCT P 54316-20 ll and “The main criteria for evaluating the chemical composition of mineral water” (V.V. Ivanov, M., 1982). Water of similar composition and properties is commonly used in drinking purposes including industrial bottlin g as natural table water (with and without fortificat ion of carbon dioxide) subject to its sanitary and bacteriological welfare (local Epidemio logy control) and in preparation of a variety of soft drinks on its basis.
Low-mineralized groundwater (as well as melt ice, snow, rain and other water with mineralization of – 0.3 g/1) can be considered fresh only chemically . As such water possesses permanent ion-saline composition, it has strong physiological effect when taking inside. If water is warmed up to 37-38°C, it can be rapidly absorbed by mucous coat of stomach and upper sections of small intestine, penetrates in the interna! env ironment through physiological membranes, normalizes metaboli c, immunological and reparative processes in the direction of their qualitative improvemet.
lt should bc noted that the indicators of water well BQ-2 (Rogatets-Sobonki, the Czech Republic) coiTespond to the fundam entals and requirements of the national standard and GOCT P 54316-20 ll «Natural mineral drinking water. General technical requ irements». lt was approved by Federal Agency for technical regul ation and meteorology on 151 July, 20 12.
Accord ing to this normative document – fOCT P 54316-20 ll – water of well BQ-2 corresponds to mineral natural table water.
In addition the water source (well BQ-2) is close to water of higher or first quality categories by main ind icators of macroion and microcomponent chemical composition (SanRegN 2. 1 .4.1116-02 “Drinking water. Hygienic requirements for water quality in bottles … “) and can be used without limits as drinking with appropriate water conditioning and bottling.
We have made calculations of hypothetical main salt composit ion of the tested water to measure water salinity according to the scheme adopted in the practice of hydrogeochemical research (see. E.V. Posohov “General hydrogeochemistry”, Leningrad, “Nedra”, 1975). The given results are summarized in the table.
Hypothetical salt water content ofwell BQ-2 (Rogatets-Sobonki, the Czech Republic; LLC “Svyatopram en” (Yubileini , Moscow region) for Bohemia Beverage In-dustry Group s. r. o.)
|NN Composition name||Chernical formula||Salt content, g/1|
We can see that sodium, calcium and magnesium hydrocarbonates dominate in hypoth etical salt content, thou gh their concentration is far from saturation point of natural solution with these components. In accordance with well-known literary data in soft drinks manufacturing, the composition and properties of the used water play a great role: water hardness (temporary and permanent), its alkalinity, concentration of some components, etc. From this point of view, this water is characterized by low hardness (eliminable) dueto low minerali zation and low content of hydrocarbonate alkaline-earth elements; the value of total hardness is – 1.2 mg-eq u/1 (drinking water standard of thc central water supply is not more than 7.O mg-equ/1); permanent (sulfate) hardncss caused by CaS04 and other calcium and magnesium salt is not specific to the spring. Total alkalinity almost corresponds hydrogen carbonate content and is approximately 3.3 mg-equ/ 1; attracts extremely low content of iron ions (0.05 mg/1) and relatively high content of silicic acid which in term s of H2Si03 is 17.0 mg/1 (6.1 mg/1 in Sielem – MPC for drinking water 10 mg/1).
According to GOCT P 54316-2011 and technological processing and bottling instructions of dri nking mineral water TI 18-6-57-84, silver sulphate treatment is allowed to decontaminate mineral water containing chloride ions not more than 0.289 g/1, sulfate-ions not more than 0.854 g/1, hydrocarbonate ions not more than 1.366 g/1 (residua! concentration of si lver ions in the water is no more than 0.2 mg/1). The water of the spring has stable chemical composition and mcets the specified requirements (see. analysis form) and therefore can be processed with silver sulfate while bottling.
This study inclu des comprehensive indicators characteristics according to the adopted standards of the Russian Federation and international standards for drinking water.
- Fresh underground water of well BQ-2 (Rogatets-Sobonki, the Czech Republic; March 2013, LLC «Svyatopramen», Yu bileini, Moscow region, for Bohemia Beverage Industry Group, s.r.o.) refers to mineral natural tahle water of hydro carbonate calcium-sod ium (or magnesium-calcium-sodium) content without specific components and propert ies and meets the requ irem ents of regulatory documents to minera l natural table water (GOCT P 54316-20 ll).
- Mineral natural table water of well BQ-2 (Rogatets-Sobon ki, the Czech Republic; Bohemia Beverage Industry Group, r. o.) meets the requirement s of normative documents by its chemical composition and properties and differs with its stable chernica l composition , it does not contain any harmful and toxic components and it is recommended for drinking water use including industrial bottling (with or with out carbonation) as well as for production of various drinks on its basis in accordance with the normative and technical documentation for the given product provided sanitary and bacterio logical water welfare and water intake.
