Water quality monitoring data

Water quality affects health, ecosystems and compliance, and monitoring data makes it visible. This guide covers water quality data and how to source it.

Why water quality data matters

Pollution, health and regulation drive the need for water quality data across rivers, groundwater, bathing and drinking water. It supports compliance, environmental management and risk.

The data landscape

• Surface water: river and lake quality.
• Groundwater: aquifer quality.
• Bathing and drinking: regulated quality data.
• Sensors: continuous monitoring.

Common use cases

Regulatory compliance and reporting, environmental and health risk, utility operations, and ESG.

Sourcing considerations

Official monitoring networks (under EU water directives) provide much data, with sensors adding continuity. Parameters and methods vary, so harmonisation and provenance matter. Combining with location and catchment data adds value.

Delivery and governance

Operations want near-real-time sensor data; compliance uses periodic data. Most is non-personal. Provenance matters for regulated reporting.

In a managed model

A managed partner can combine network and sensor water-quality data, harmonised and documented.

Networks plus sensors

Water quality data spans surface, groundwater, bathing and drinking water from official monitoring networks (under EU water directives), with sensors adding continuity. Parameters and methods vary, so harmonisation and provenance matter.

Cadence and context

Operations want near-real-time sensor data while compliance uses periodic data; combining with location and catchment data adds value.
