METHODOLOGICAL INFORMATION

Description of Dataset
This dataset contains field-based redox and water chemistry measurements collected from the Clifton Integrated Constructed Wetland (ICW) during 2025.

The dataset includes physicochemical measurements associated with:

* oxidation–reduction potential (ORP),
* dissolved oxygen dynamics,
* pH,
* temperature,
* and associated environmental conditions within the treatment wetland system.

The dataset was developed to investigate:

* redox gradients,
* oxygen availability,
* nutrient transformation conditions,
* and environmental controls on treatment wetland biogeochemical processes.

Description of Data Collection
Field measurements were collected from multiple locations throughout the treatment wetland system using portable field instrumentation and in situ monitoring procedures.

Monitoring locations included:

* influent locations,
* internal wetland compartments,
* and outlet locations.

Measured parameters may include:

* Oxidation–Reduction Potential (ORP)
* Dissolved Oxygen (DO)
* pH
* Temperature
* Electrical Conductivity (EC)
* Turbidity
* Sampling location
* Sampling depth

Analytical Methods

Field Measurements
Physicochemical measurements were undertaken in situ using calibrated portable field probes and multiparameter monitoring equipment where applicable.

ORP Measurements
Oxidation–reduction potential measurements were used to assess redox conditions and potential anaerobic or aerobic zones within the treatment wetland system.

Water Chemistry Measurements
Water chemistry parameters including dissolved oxygen, pH, conductivity, and temperature were measured during field sampling campaigns.

Experimental Conditions
Sampling was undertaken under operational full-scale wastewater treatment wetland conditions during 2025.

Measurements represent real-world hydraulic, environmental, and treatment wetland conditions.

Quality Assurance / Quality Control (QA/QC)

* Field instrumentation was calibrated prior to sampling.
* Sampling procedures were standardised across monitoring locations.
* Measurements were checked for consistency and transcription errors prior to analysis.
* Missing values were retained as blank cells where applicable.
