Final effluent spot sampling vs continuous monitoring

Final effluent spot sampling versus continuous monitoring. This project will be completed via an evidence gathering desk top exercise focused on, but not limited to, sampling data, a review of relevant literature, academic papers, policy documents, operational documents, technical documents, discussions with those undertaking final effluent Operator Self Monitoring and continuous monitoring, research and development, video/webinar presentations. Some statistical analysis will be essential to understand the differences between the two sampling methods.

The information gathered will be presented and summarised in a written technical report. Sample data, graphs and statistical analysis will be included within the report. This research project will be completed over a 3 month period.

Additional information: Question:

Does the EA have any data sets for comparing continuous versus spot samples?

Answer:

The EA has spot sampling via OSM from the Water Companies, but continuous data would need to be sourced from the Water Companies. This data can be documented as anonymous if needed.

Question:

The bid document does not discuss working with European partners. This is then introduced as a specific question in the detailed evaluation questionnaire. Is this left over from a previous document, or are the EA expecting that European experience in this area be included with direct involvement of partners?

Answer:

Sorry it was left over from a previous document. Thank you for making us aware. No European experience is needed for this project.

Question:

The bid document requests quantifying risks and opportunities. What is the EA looking for as regards quantification?

Answer:

The risks of using spot sampling, continuous monitoring and potentially using both together. The same for opportunities. What are the risks of only using spot sampling for example. What are the opportunities of using continuous monitoring? How this is quantified is left open for the consultant to decide.
