This document discusses biological contamination of coastal bathing waters. It notes that contamination is often from fecal matter and lists various pathogens that can be present, including viruses, protozoa, bacteria, and parasites. Testing all possible pathogens is impractical, so indicator bacteria like E. coli and intestinal enterococci are used instead as they are fast, inexpensive alternatives. The EU Bathing Water Directive classifies waters based on these indicators. The Smart Coasts project aims to better understand sources of pollution to allow more bathing waters to meet standards and retain their "Blue Flag" designation for tourism through modeling, monitoring, and public information tools.

It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.

Water Conservation Finds It’s Home in Integrated Resources Planning. Presented by Richard Harris, Manager of Water Conservation, East Bay Municipal Utility District, California at Texas Water Foundation, Central Texas Water Conservation Symposium February 26, 2013
Jenny Deakin from the EPA Catchments Unit gave a Teagasc Signpost Seminar on April 20 2021. The seminar covered water quality, focused on the agricultural sector, and the solutions needed to improve water quality, and new tools to target the right measure in the right place. This includes upgraded Pollution Impact Potential Maps for Nitrogen and Phosphorus, together with overland flow and focused delivery points.
On 25 November 2020 the EPA published Ireland’s Environment - An Integrated Assessment 2020 which provides an assessment of the overall quality of Ireland's environment, the pressures being placed on it and the societal responses to current and emerging environmental issues.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s rivers.
Ireland has more than 73,000 km of river channels. If placed end-to-end, they could encircle the Earth almost twice. Three-quarters of these channels are very small streams that typically flow into larger rivers.
Biological monitoring has been carried out in Irish rivers since 1971. The current national river monitoring programme covers more than 13,000 km of river channel.
The national monitoring programme is run by the EPA and focuses on the main river channels rather than the smaller streams. The programme includes more than 2,800 sites sampled for biology, with almost half of these being sampled for physical and chemical parameters.
This plain English fact sheet outlines the work done by the EPA in monitoring phytoplankton in Ireland's marine environment.
The EPA and the Marine Institute sample phytoplankton in estuaries and coastal waters around Ireland. They carry out sampling three times during the summer and once during winter. At each location, they take water samples just below the surface and above the seabed. They use the samples to assess how much phytoplankton is in the water and what species are present.
Phytoplankton are tiny, free-floating plants found suspended in the world’s oceans. Their name comes from Greek and means ‘plant drifter’. They are carried along by ocean currents and are usually found floating near the surface of the water. Like all plants they need sunlight to grow.
The main sources of nutrients around Ireland’s coast are discharges from wastewater treatment plants and run off from agricultural land. Phytoplankton in the estuaries and coastal waters around Ireland are monitored by the EnvironmentalProtection Agency (EPA) and the Marine Institute. They monitor phytoplankton to assess the quality (status) of our marine environment. They must do this as part of the requirements of the European Water Framework Directive.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s marine environment.
Ecologically healthy marine waters are a valuable natural resource. They support a rich and diverse range of ecosystems, habitats and species, and they are also a source of food – from wild fisheries and aquaculture. They are also important for recreational activities and tourism.
Transitional and coastal waters are assessed under the European Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). Having coordinated frameworks for water quality for all the water bodies in Ireland, and across Europe, allows us to compare our results with other countries. It allows us to see what works to help us make sure all our water bodies achieve at least ‘good’ status, and no deterioration occurs.
This plain English fact sheet outlines the work done by the EPA in monitoring Ireland’s lakes.
A total of 225 lakes are currently included as part of the national surface waters monitoring programme run by the EPA, this covers around 80% of the surface area of all lakes in Ireland.
This includes:
• all lakes greater than 50 hectares
• lakes that are used for supplying drinking water
• lakes that are of regional, local or scientific interest
This Plain English fact sheet outlines the work done by the EPA in monitoring aquatic plants in Irish lakes.
Aquatic plants are good at showing if the quality of the water is good or bad and play an important role in lake ecology by providing food and a habitat for many smaller plants, animals and birds.
They also:
• provide shelter for young fish
• help to improve the clarity of the water
• help stabilise lake shore banks
• reduce the amount of sediment being suspended in the water
The Environmental Protection Agency (EPA) monitors these aquatic plants at more than 10,000 sites in over 200 lakes once every three years.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
