Funding Source
This dataset was compiled and analysed as part of a PhD research project investigating long-term treatment wetland performance, nutrient dynamics, and compliance behaviour in integrated constructed wetlands.

METHODOLOGICAL INFORMATION

Description of Dataset
This dataset contains historical operational water quality monitoring data collected from the Clifton Integrated Constructed Wetland (ICW) between 2010 and 2025.

The monitoring programme formed part of routine wastewater treatment operational and compliance monitoring undertaken by Yorkshire Water.

The dataset was subsequently compiled, cleaned, processed, and analysed for academic research purposes at Cranfield University.

The dataset includes long-term monitoring records associated with:

* wastewater treatment performance,
* nutrient removal,
* suspended solids attenuation,
* organic matter reduction,
* and operational treatment behaviour.

Description of Data Collection
Samples were collected from designated monitoring locations throughout the treatment wetland system using routine wastewater operational monitoring procedures.

Monitoring data may include:

* influent measurements,
* intermediate treatment cell measurements,
* and final effluent monitoring data.

Measured parameters may include:

* Biochemical Oxygen Demand (BOD5)
* Chemical Oxygen Demand (COD)
* Total Suspended Solids (TSS)
* Total Phosphorus (TP)
* Orthophosphate Phosphorus (Ortho-P)
* Total Nitrogen (TN)
* Ammonium Nitrogen (NH4-N)
* Nitrate Nitrogen (NO3-N)
* Dissolved Oxygen (DO)
* pH
* Temperature

Analytical Methods
Water quality analyses were undertaken using standard wastewater analytical procedures and accredited laboratory methods where applicable.

Experimental Conditions
The dataset represents operational full-scale wastewater treatment wetland conditions under varying hydraulic loading, seasonal conditions, and environmental conditions over the monitoring period.

Quality Assurance / Quality Control (QA/QC)

* Sampling and laboratory analyses were undertaken as part of routine wastewater operational monitoring procedures.
* Analytical QA/QC procedures associated with the original monitoring programme were undertaken by Yorkshire Water and associated laboratories.
* Data cleaning and formatting were undertaken prior to academic analysis.
* Missing or unavailable measurements were retained as blank cells where applicable.
* Historical datasets may contain variations in monitoring frequency over time.
