Summary

BACKGROUND

Drinking water treatment is an intensive process with high materials and energy costs incurred between raw water and consumer supply. Of particular concern to suppliers is the presence of human health and taste agents such as pesticides, sediments, nutrients, bacteria, viruses and colour. Land use upstream of raw water intakes in rivers is fundamental in driving these treatment needs with agriculture and forestry practices implicated. The selective herbicide MCPA is an issue in upland raw water catchments throughout Ireland and the UK and is linked to incentives to maintain a grass sward in marginal areas. Slurry management on intensive meadows and pastures increases total ammonia and pathogen vulnerability and toxicity in raw water and is related to changing storm runoff patterns as these are affected by climate change. Forestry felling and land drainage practices alter sediment mobilisation and organic carbon dynamics.

PROJECT FRAMEWORK

The overall project aim will be to develop risk assessments of raw water vulnerability and provide assessments of catchment management effectiveness. This will be based on analyses of extant long-term datasets and new datasets collected during the research. The objectives are: 1.Investigate MCPA vulnerability and mitigation effectiveness of catchment-pesticide measures 2.Determine sediment and organic matter vulnerability and mitigation effectiveness of catchment-forestry measures 3.Determine nutrient vulnerability in space and time and establish best practice. 4.Provide a catchment-modelling framework for risk, sensitivity and management.

METHODS

The four objectives will operate at different scales but within a framework of important cross-border raw water supply catchments. Objective no1 will operate on extensive and mixed pasture areas using catchment scale data and soil scale process experiments; 2 will operate in afforested and deforested areas; 3 will operate on intensive pasture/meadow land. Risk assessments will be GIS based and numerical time series analysis will inform management effectiveness. Objective 4 will incorporate all extant and new data into a Bayesian modelling framework for risk and management.

IMPACT and COLLABORATIONS

This research is related to the needs of society through the sustainable provision of drinking water that is protected at source, with reduced treatment costs. Research impact is therefore explicitly part of the project structure and the Ulster University SUSTAINABILITY core theme. Northern Ireland Water, Irish Water, the Rivers Trust and AFBI are all major actors and stakeholders in the research and linked through the £5million 5year EU-INTERREG Va ‘Source to Tap’ project. Additionally, AFBI researchers will be part of the external supervisory panel with regard to objectives 1 to 4 and the James Hutton Institute, Aberdeen, will provide specialist supervisory input to objective 4.

SKILLS and OUTPUTS

The PhD candidate will develop skills in spatial analysis, water quality and climate time series analysis, statistical modelling, environmental measurements using state-of-the-art techniques, field-work and scientific writing. There will be opportunity for international conference presentation, stakeholder engagement and a requirement for the preparation of manuscripts for scientific journals. Primary target journals will be relevant for Five and Fifty objectives including Water Research, Environmental Science and Technology and Environmental Modelling and Software.

Funding

Vice Chancellors Research Scholarships (VCRS)

The scholarships will cover tuition fees and a maintenance award of £15,009 per annum for three years (subject to satisfactory academic performance). Applications are invited from UK, European Union and overseas students.

DFE

The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £15,009 per annum for three years. EU applicants will only be eligible for the fees component of the studentship (no maintenance award is provided).  For Non EU nationals the candidate must be "settled" in the UK.
