In this project three Irish estuaries were modelled with the aim of quantifying the impact on water quality of existing nutrient loading from direct and diffuse inputs. Recommendations on the necessary nutrient load reductions to improve estuarine water quality and the appropriate pressure to target in nutrient load reductions for the three systems studied are provided.

One important challenge in the 21st century is the ability to provide a clean and pollutant-free source of water. This project aimed to develop electrochemical and optical-based sensors for detection of organic contaminants (herbicides) and heavy metals. This research has shed light on the potential for the development and optimisation of novel environmental sensors and anti-biofouling strategies.

Vartry Reservoir is a very important drinking water source in Ireland. This project collected and analysed historical water quality and ecology data from 2016 to 2018 and a series of laboratory experiments were carried out to investigate the causes of diatom blooms to identify the pressures. The study also monitored nutrient levels in both the feeding rivers and the reservoir.

Water sampling remains a key component in the monitoring and assessment of aquatic environments. Sampling requiring the use of a boat can lead to issues around accessibility, particularly at remote lakes where there may be a lack of a slipway. This research has successfully demonstrated that water chemistry data collected using drone water sampling methods are not statistically different from those produced by boat sampling.

Loss of pollutants from grassland systems to water bodies is a significant threat to water quality and represents one of the main environmental problems facing agri-ecosystems in Ireland. This project evaluated existing literature and generated temporal and spatial data on the environmental impact of cattle exclusion measures.

Coastal saltmarshes provide a range of important ecosystem services but face increasing challenges because of human activities. Ecological assessments of saltmarshes are required to inform reporting in compliance with the European Union (EU) Habitats Directive (HD) (92/43/EEC) and Water Framework Directive (WFD) (2000/60/EC).

This project developed a new online national WRI database by collaborating with the water research community in Ireland, using an interactive consultation and design process. It is a central database of information on all WRI in Ireland, including the types of WRI available for various research areas and applications, from the freshwater sector to the marine, climate and agriculture sectors.

This project addresses water reuse in the context of the circular economy in Ireland. This study has reviewed the policy background for water reuse; assessed the international practices in water reuse; examined the main technologies that are used for water recovery and their suitability; and conducted significant stakeholder engagement, including the first national public survey on attitudes to water reuse in Ireland.

There are many variables which must be considered when designing and operating a wastewater treatment system. The key objectives of this research were to develop software tools to assist in the selection and management of wastewater treatment systems, with a specific focus on small wastewater treatment plants in Ireland.

This research project evaluated the impact of domestic wastewater treatment system (DWWTS) effluent as a health hazard to consumers of groundwater from private wells and also a source of nutrient water pollution to surface water in small catchments.

Nutrient enrichment and eutrophication can negatively impact on freshwater ecosystems, estuarine and coastal waters. As a result of improvements in nutrient management and regulation, there has been a large reduction in total phosphorus, total ammonia and total nitrogen emissions from Irish catchments in recent decades.

In Ireland, most urban areas are drained by combined sewer systems, which convey wastewater and stormwater in a single pipe. During rainfall the capacity of combined sewers may be exceeded, leading to untreated discharges to receiving waters via storm water overflows (SWOs), which are a source of microbial pathogens.
