## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## EU Groundwater Threshold Value Records — EEA WISE

**Keyless. Pay per record. Official groundwater pollutant threshold values and trend-reversal points, river basin by river basin.**

This actor turns the **European Environment Agency (EEA) WISE Water Framework Directive (WFD) database** into clean, per-record data — the official pollutant threshold values and trend-reversal starting points set for Europe's groundwater bodies. Each run reads the EEA's keyless DiscoData SQL service and delivers one row per threshold-value record, structured for environmental and water-management analysis, reusable with acknowledgement of the EEA, with no personal data of any kind.

### What this is, in one paragraph

Under the Water Framework Directive and Groundwater Directive, member states set threshold values for the pollutants that matter in each river basin district, and the point at which an upward pollutant trend must be reversed. This actor reads that table and delivers one record per threshold: the country and river basin district, the pollutant indicator, the threshold value RANGE and UNIT in the SOURCE UNITS verbatim, the scale at which it was set, the trend-reversal starting point, and the comparator drinking-water values where reported. It is the regulatory-threshold layer of Europe's groundwater assessment.

### Who buys this and for what job

- **Hydrogeologists and groundwater analysts comparing national threshold values across basins**
- **Water-utility and regulatory teams benchmarking pollutant thresholds and trend-reversal points**
- **Researchers studying how member states set groundwater standards**
- **Data engineers** who want the WISE WFD threshold-value table as clean rows from a keyless source.

### EEA licence — reuse with acknowledgement

One licence rider travels on every record. EEA data may be **reused, including commercially, provided the source is acknowledged**: "Source: European Environment Agency (EEA)." Where third-party content is marked, it keeps its own terms. These are reported values and status labels as filed — not a compliance verdict.

### Water-body grain — no person data

The unit of every record is a threshold value for a pollutant in a river basin district — a water body and its reported attributes, never a person. WISE WFD reporting is at water-body / river-basin level: there is **no contact, operator, or responsible-person field** in the source table, and none is selected or emitted — the query reads only the water-body identity, the status labels, and the threshold value, unit, scale, and trend-reversal point. A person-key guard runs on every record as a backstop. The `file_url`, where present, points to the official EEA/Eionet reporting file (an organisation reporting system), never a person.

}
```

An unbilled `RUN_RECEIPT` records the robots check, the filters, rows seen and delivered, and whether charged equals delivered.

### Field reference

Each record is one threshold value. Identity: `record_id`, `country_code`, `country_name`, `eu_rbd_code`, `rbd_name`, `rbd_area`, and `reporting_year`. Pollutant: `pollutant_indicator_code` and `pollutant_indicator_code_other`. Threshold: `threshold_value_range`, `threshold_value_unit`, `threshold_value_scale`, `starting_point_trend_reversal`, and `threshold_derived_from_cv`. Comparators: `cv_drinking_water_value_range` and `cv_drinking_water_value_unit`. Plus `has_descriptive_data` and `file_url`. Provenance travels on every record: `source`, `source_url`, `licence`, `attribution`, `disclaimer`, and `observed_at`.

### How a run works

A run first re-reads the source host's robots posture from your runtime — the EEA DiscoData host — and stops at the door if that ever changes. It pages the WISE WFD threshold-value table (filtered to your optional `countryCode` and `year`), and flattens each row to one record — carrying every status label and value **verbatim**, never anything person-shaped — delivered **before** it is charged, so a blocked or empty run costs you nothing. The actor stops at your `maxRecords` ceiling and records `charge_equals_delivered` in the receipt.

### Coverage and scope

The table holds on the order of **16,336 rows** across reporting countries, river basin districts, and the 2016 and 2022 WFD reporting cycles. Because each record carries the `country_code`, the water-body identity, and the `reporting_year`, segmenting by country, basin, or cycle is straightforward. Pull one country, or the whole table to seed a water-status warehouse.

### Identifiers and joins

Every record carries the `eu_rbd_code`, the river-basin-district identifier that keys each threshold value to the fleet's other WISE cells — the groundwater bodies in that basin, their chemical-status exemptions, and the pollutants recorded as causing failure. A buyer can therefore line up a basin's regulatory thresholds against the actual exemptions and failures reported for its water bodies on a shared identifier, and the `reporting_year` keeps successive cycles separable for trend work.

### Working with the data

The threshold values are a standards reference, and the fields make them comparable. Because every record carries a `pollutant_indicator_code` with a `threshold_value_range` and `threshold_value_unit` in the source units, an analyst can compare how strictly two countries regulate the same pollutant without unit-guessing, and the `starting_point_trend_reversal` exposes where each basin flags a rising trend for action. The `reporting_year` frames each value in its cycle.

### Cost guidance

One `threshold_value_record` per delivered row: cost = rows delivered × your plan's per-record price. Scope with `countryCode` and `year` to keep runs bounded. 1,000 rows is **$50** (Free) / **$33.50** (Gold).

### Honest limitations

- **As reported.** Status labels and values are as filed by member states for the WFD reporting cycle; this actor reformats, it does not audit or recompute.
- **A status label, not a verdict.** These are reported classifications and exemptions, not an independent compliance assessment.
- **Two cycles merged.** The table carries both the 2016 and 2022 reporting cycles; the `reporting_year` field distinguishes them — filter on it if you want a single cycle.
- **Acknowledge the EEA.** The acknowledgement travels on every record.
- **No person data** of any kind.

### Differentiation

This is a **net-new** category for the NexGenData fleet. It is distinct from the fleet's status and monitoring water cells — this is the regulatory THRESHOLD layer (the values against which groundwater is judged), not a status classification or a monitoring measurement. It complements **eu-groundwater-chemical-exemption-records** (the exemptions) and differs entirely from the Nitrates, Bathing Water, and Urban Waste Water directive cells. Its specific job is the **WFD groundwater threshold values and trend-reversal points**.
