Testing your drinking water
Testing your drinking water: for everyone on a private well or borehole — a large share of rural Estonia and Finland — plus anyone who wants their tap water…
This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
For everyone on a private well or borehole — a large share of rural Estonia and Finland — plus anyone who wants their tap water checked. One page per parameter: E. coli and coliforms, nitrate, nitrite, iron, manganese, fluoride, arsenic, radon in water, hardness, pH, ammonium, sulphate, chloride, turbidity, uranium; each with the legal limit, what a number over it means for whom (infants and nitrate above all), and what fixes it.
Plus how to take a sample without spoiling it, which laboratory is accredited in each country, what a full analysis costs, how often to repeat, and a "read my lab report" walkthrough.
How to use it
Use Testing your drinking water to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | kaevuvee analüüs kust tellida |
| Finnish | kaivoveden tutkimus hinta ja ohjeet |
| Russian | анализ воды из скважины какие показатели |
| English | well water test nitrate safe level |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: WHO Guidelines for Drinking-water Quality (4th ed., public), EU Drinking Water Directive 2020/2184 parametric values, Finnish STM asetus 401/2001 for small units, Estonian Terviseamet accredited-laboratory list. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
