What each contains
Pick by fit, not by loyalty.

|---|---|---|
| Geography key | `countryCode` - abbreviation of the reporting EEA member or collaborating country | `Country Name` plus ISO3 `Country Code` (e.g. Brazil / BRA) |
| Place identity | `monitoringSiteIdentifier` / `spatialUnitIdentifier` - international WISE identifier for a site, river basin district or sub-unit | None carried - the frame stops at the national border |
| What is measured | `observedPropertyDeterminandCode` / `Label` - substance or parameter from the Eionet codelist (e.g. CAS_7440-09-7 / Potassium) | `Indicator Name` - the development indicator in prose (e.g. People using safely managed drinking water services (% of population)) |
| Series identity | Composed from table context and dimensions rather than one column | `Indicator Code` such as `SH.H2O.SMDW.ZS` or `ER.H2O.FWST.ZS` |
| Time anchor | `phenomenonTimeReferenceYear` integer, with `parameterSamplingPeriod` giving the ISO interval covered (e.g. 2011-01--2011-12) | Wide `<year>` columns running back to 1960 where observations exist |
| Observed value | `resultMeanValue` with `resultMinimumValue` / `resultMaximumValue` alongside, typed by `resultUom` (e.g. mg/L) | Numeric cell under each year column; blank where no observation exists |

What each does better
EEA Data and Maps - Water
Determinand-level chemistry nobody else publishes at this grain. Waterbase reports aggregated statistics per monitoring site, determinand and year - a potassium reading at a French river site prints as FRGR04067200, CAS_7440-09-7 / Potassium, reference year 2011, mean 3.15 mg/L. Minimum and maximum ride alongside the mean, so dispersion comes built in rather than reconstructed; see Waterbase.
Emissions, not just state. The Waterbase - Emissions 2026 release carries 1977 through 2025 of loads to surface waters from point and diffuse sources, keyed by country and spatial unit. That is the pressure-accounting layer a compliance review or ESG emissions analysis workflow needs upstream of any outcome claim.
Deep history. Water Quality ICM spans 1900 through 2024, a century-scale baseline for trend work that few water records anywhere can match; the Bank's water columns begin in 1960 at the earliest.
World Bank Water & Sanitation Topic Data
Outcomes and access, globally framed. Safely managed drinking water, basic and safely managed sanitation, handwashing hygiene - series aligned with the WHO/UNICEF Joint Monitoring Programme - sit beside freshwater withdrawal and resource accounts, freshwater-withdrawal intensity, water productivity, marine protected areas and private participation investment in water and sanitation (IE.PPI.WATR.CD). The EEA record measures the resource; this one measures whether people received service.
Comparability across borders. Roughly 200 countries and economies share one annual country-indicator-year grid, with World Bank regional and income aggregates precomputed - so cross-country benchmarking needs no harmonization step. That is why the record suits citation-grade research as readily as market sizing.
A tidy join key. One row per country and indicator in long form - or one column per year in wide form - means a spreadsheet filter is already most of the pipeline. The related environment topic export alone runs about 39,000 rows across roughly 147 indicators, a sense of scale for the family.
The verdict
Verdict: sample both, pick by fit. Let the unit of analysis decide. If your question names a place smaller than a country - a monitoring site, a river basin district, a single determinand in a given year - EEA Data and Maps - Water is the only instrument shaped for it. If your question names a country, or compares many - access coverage, withdrawal totals, stress levels, investment flows - World Bank Water & Sanitation Topic Data answers it directly on a common grid.
Because both records score a straight 8/10, neither wins on craft; they win on different questions. Cut each sample to the sites, determinands, countries and years you actually model, and let the returned rows make the call rather than the brand names.

Fair questions
Is EEA Data and Maps - Water better than World Bank Water & Sanitation Topic Data?
Different instruments, tied on craft - both score 8/10. The EEA wins whenever the question is physical and specific: determinand-level statistics at a named monitoring site, emissions loads by spatial unit, quality series reaching back to 1900. The Bank wins whenever the question is human and comparative: who holds safely managed water, how much each economy withdraws, where investment flows. Many desks keep both.
Which dataset reaches further back in time?
The EEA on quality, the Bank on breadth. EEA Waterbase quality releases span 1900 through 2024 and its emissions series begins in 1977; the Bank's year columns begin in 1960 where observations exist, with featured years running 2000 through 2025. For century-scale chemical baselines the EEA leads; both cover the most recent two decades comfortably.
Do the two datasets overlap anywhere?
On national aggregates. Several EEA tables roll monitoring-site results up to country level, meeting the Bank's strictly national frame, and both touch the quantity story - EEA water-quantity tables beside the Bank's withdrawal, resource and stress series. Elsewhere they complement rather than compete: site-level chemistry and emissions on one side, access, hygiene and investment outcomes on the other.
Which one should a water utilities analyst sample first?
Sample both, pick by fit - the jurisdiction decides. For European catchments and regulatory evidence, start with [EEA Data and Maps - Water](/datasets/water-utilities/eea-data-and-maps-water) and its site-level determinand record. For market entry, benchmarking or investor questions outside Europe's perimeter, start with [World Bank Water & Sanitation Topic Data](/datasets/water-utilities/world-bank-water-sanitation-topic-data). Samples arrive cut to your sites, determinands, countries and years either way.
Can Datadory deliver both datasets together?
Yes. Either record arrives alone or merged onto one delivery calendar with the join already done - country keys reconciled and site rows rolled up to country-year where needed - delivered daily, weekly, or hourly, your call. Name the sites, determinands, countries and windows when you request the sample and it lands pre-cut, with field definitions and coverage profiles attached.
