In August 2026 the accredited Ekomedservice Ecological Laboratory (DSTU EN ISO/IEC 17025, NAAU certificate No. 20678) tested all three of Arctica’s drinking-water lines. The samples were taken on 4 August 2026; test reports No. E019/26 (Ridna Voda), No. E020/26 (Ridna Kraplyna) and No. E021/26 (Arctica) were approved on 10 August 2026. The conclusion is the same in each: the water complies with the requirements of DSanPiN 2.2.4-171-10, the Ukrainian drinking-water standard, for physico-chemical parameters. In all three lines odour and taste score 0 points against a limit of 2, nitrates are below 0.44 mg/L against a limit of 50, lead below 0.005 against 0.01, iron below 0.01 against 0.2. The lines differ in their mineral composition: Ridna Voda is the softest (total hardness 0.16 mmol/L, dry residue 25.0 mg/L); Ridna Kraplyna carries magnesium (15.8 mg/L), Arctica both calcium and magnesium (11.0 and 10.3 mg/L); both have a hardness of 1.4 mmol/L and a dry residue of 123.0 and 133.0 mg/L respectively.
Below: every parameter of the three reports next to its limit, scans of all six sheets, and the previous report for Ridna Voda from September 2025 for comparison over time.
On the safety parameters the three lines do not differ: lead, iron, manganese, nitrates and ammonium are below the detection limit of the method in all three, and permanganate oxidisability is 0.8–0.88 mg/L against a 5.0 limit. The difference lies only in the amount of dissolved salts — and that is exactly what is worth understanding when choosing a water.
The softest of the three
Reverse-osmosis water with almost no dissolved salts: a delicate, neutral taste, and practically no limescale in a kettle, coffee machine or cooler.
When to choose it: if the priority is no limescale in the kettle, coffee machine or cooler.
Moderate mineral content, magnesium-led profile
About five times more dissolved salts than Ridna Voda, with magnesium clearly ahead of calcium in the composition.
When to choose it: if you want water with minerals, magnesium above all.
The highest mineral content of the three
The highest dry residue of the three, with calcium and magnesium roughly level — the flagship water with a balanced taste.
When to choose it: if you want both calcium and magnesium in the water — the highest mineral content of the three.
The samples were taken on the same day, 4 August 2026, and tested in the same laboratory by the same methods — so the columns can be compared directly. The table repeats the reports line by line, including the parameters where our water carries fewer salts than the recommended range.

‘<’ — the parameter is below the detection limit of the method: the laboratory records that there is less of the substance than the figure shown.
** — a recommended range for mineral composition from Appendix 4 of DSanPiN 2.2.4-171-10, not a hygiene limit; see ‘What these figures actually mean’ below.
‘—’ — the parameter was not tested in the report for that line.
The limits in the second column are those of the Ukrainian standard DSanPiN 2.2.4-171-10. The testing was not carried out against Directive (EU) 2020/2184, so we make no claim about European requirements — the measured values are published so that you can compare them with whichever standard you work to.
Three things we state plainly, because they are exactly what a buyer should understand.
Appendix 4 of DSanPiN recommends 200–500 mg/L of dry residue and 1.5–7.0 mmol/L of hardness for drinking water. All three of our lines carry fewer salts than that, and we do not hide it. Ridna Voda is reverse-osmosis water with almost no dissolved salts: 25.0 mg/L of dry residue, hardness 0.16. Ridna Kraplyna and Arctica carry about five times more salts — 123.0 and 133.0 mg/L, hardness 1.4 — yet still less than the recommended range: only slightly for hardness, noticeably for dry residue. This is not a breach of the standard: compliance is assessed against Appendices 1–3, and on those all three reports conclude ‘complies’. The practical consequence is a neutral taste and little limescale. The same applies to total alkalinity: 0.4 mmol/L in Ridna Voda and Arctica against a recommended 0.5–6.5 — again Appendix 4, again a recommendation, not a limit. And the pH of Ridna Voda, 6.5, sits exactly on the lower bound of the 6.5–8.5 range: within the limit, with no margin, and we say so.
In the scans, the ‘compliance’ column for calcium and magnesium holds a dash. That does not mean ‘fails’: for these parameters there is no hygiene limit at all — only the recommended range of Appendix 4 (calcium 25–75, magnesium 10–50 mg/L). The laboratory measured the values — calcium 3.6, 2.0 and 11.0 mg/L for Ridna Voda, Ridna Kraplyna and Arctica, magnesium 15.8 and 10.3 for the latter two — but there is no mandatory figure to compare them with, so it put a dash in the cell. Magnesium was not tested for Ridna Voda: there is no such row in its report.
These are physico-chemical test reports: 24 parameters for Ridna Voda and 25 each for Ridna Kraplyna and Arctica. So we write exactly what the laboratory wrote: compliance with DSanPiN 2.2.4-171-10 for physico-chemical parameters — and we do not read more into the documents than they contain.

Samples taken 4 August 2026, testing carried out 4–10 August 2026, approved 10 August 2026. Each report is published in full, both sheets, unedited. The documents are issued in Ukrainian; the table above gives every figure in English.

Sample taken 2 September 2025, testing carried out 2–5 September 2025, the same laboratory. We keep it on the page to show how the composition of the water holds over time: within a year the safety parameters did not change, and the 2026 sample carries even fewer salts.

Yes — all three lines. Under test reports Nos. E019/26, E020/26 and E021/26 from the accredited Ekomedservice laboratory, the samples of Ridna Voda, Ridna Kraplyna and Arctica water comply with the requirements of DSanPiN 2.2.4-171-10, the Ukrainian hygiene standard for drinking water, for the physico-chemical parameters tested. Not one of the parameters tested exceeds a hygiene limit of the standard.
Yes. The laboratory took three separate samples on the same day, 4 August 2026: sample No. 1 — Ridna Voda (report No. E019/26), sample No. 2 — Ridna Kraplyna (No. E020/26), sample No. 3 — Arctica (No. E021/26). We never carry the figures of one line over to another: each column in the table on this page comes from its own document.
The Ukrainian one: DSanPiN 2.2.4-171-10. The testing was not carried out against Directive (EU) 2020/2184, so we make no claim about European requirements. What the reports do show is the measured value of every parameter next to its Ukrainian limit, so you can compare the figures with any standard you use.
In safety — not at all: nitrates, lead, iron, manganese and ammonium are below the detection limit of the method in all three. The difference is in the mineral content. Ridna Voda: dry residue 25.0 mg/L, total hardness 0.16 mmol/L — the softest. Ridna Kraplyna: dry residue 123.0 mg/L, hardness 1.4 mmol/L, magnesium 15.8 mg/L against 2.0 of calcium. Arctica: dry residue 133.0 mg/L, hardness 1.4 mmol/L, calcium 11.0 and magnesium 10.3 mg/L.
If the priority is no limescale, take Ridna Voda: total hardness 0.16 mmol/L against a limit of 7.0 — more than 40 times lower, which means there are almost no hardness salts in it. In Ridna Kraplyna and Arctica the hardness is 1.4 mmol/L — still five times below the limit, so there will be little limescale, but some is possible.
Appendix 4 of DSanPiN 2.2.4-171-10 recommends 200–500 mg/L of dry residue and 1.5–7.0 mmol/L of hardness for the mineral composition of drinking water. It is a recommendation, not a hygiene limit: compliance is assessed against Appendices 1–3, and on those all three reports conclude ‘complies’. Ridna Voda is reverse-osmosis water with almost no dissolved salts; Ridna Kraplyna and Arctica carry noticeably more (123.0 and 133.0 mg/L), yet still less than the recommended range: only slightly for hardness (1.4 against 1.5), noticeably for dry residue (against 200). We state this plainly rather than hide it.
Ekomedservice Ecological Laboratory, 42/44 Syretska St., Kyiv. The laboratory is accredited by the National Accreditation Agency of Ukraine to DSTU EN ISO/IEC 17025, NAAU certificate No. 20678, valid until 27 September 2027. All three reports were approved by the head of the laboratory on 10 August 2026.
All three samples were taken and delivered to the laboratory on 4 August 2026; the testing ran from 4 to 10 August 2026 and the reports were approved on 10 August 2026.
For Ridna Voda there is a previous report, No. E076/25, from September 2025 — it is published on this page in the Archive section. Within a year the safety parameters did not change (nitrates below 0.44, lead below 0.005), and the 2026 sample carries even fewer salts: hardness 0.18 → 0.16 mmol/L, dry residue 32 → 25.0 mg/L.
