METHODOLOGICAL INFORMATION

Description of Dataset
This dataset contains historical treated effluent water quality monitoring data collected from the Glaslough Integrated Constructed Wetland (ICW) between 2010 and 2017. The monitoring programme formed part of routine wastewater treatment operational and compliance monitoring undertaken by Uisce Éireann.

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

The data represent long-term treated effluent quality and associated nutrient concentrations under operational full-scale wetland treatment conditions.

Description of Data Collection
Samples were collected from treated effluent monitoring locations associated with the integrated constructed wetland system using routine operational wastewater monitoring procedures.

The dataset includes measurements related to:

* Organic matter concentrations
* Suspended solids
* Nitrogen species
* Phosphorus concentrations
* pH
* Long-term treatment performance

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

Parameters measured may include:

* Biochemical Oxygen Demand (BOD)
* 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)
* pH

Experimental Conditions
The dataset represents real-world operational monitoring data collected under varying seasonal, hydraulic, and wastewater loading conditions within a municipal integrated constructed wetland system.

Quality Assurance / Quality Control (QA/QC)

* Sampling and laboratory analyses were undertaken as part of routine wastewater treatment monitoring procedures.
* Analytical QA/QC procedures associated with the original monitoring programme were undertaken by Uisce Éireann and associated laboratories.
* Data cleaning and formatting were undertaken prior to academic analysis.
* Missing or unavailable measurements were retained as blank cells where applicable.
