The EPA's Monitoring and Assessment Role
The EPA monitors environmental pollutants and radiation to assess the impact on the environment and human health. Monitoring is undertaken across a broad range of thematic areas to provide a reliable and meaningful assessment of our environment. Information is made available to the public, stakeholders and policymakers to help them make informed decisions.

Where can I find information on bathing water quality at my local beach?
Before you visit the beach this summer with your family or friends, check out www.beaches.ie or our Twitter feed @EPABeaches
Before going to the beach you can check beaches.ie to see the latest bathing water quality (excellent, good, sufficient or poor) and find out if there are any current warnings or advice against swimming notices.
• At the beach or lake – lifeguards will fly the red flags when bathing waters are considered unsafe for bathing. You can check out the notice boards to see the latest water quality and if any warnings or advice against bathing notices have been posted by the local authorities.
• The 48-hour rule after heavy rain – swimming after heavy rainfall carries an added risk of pollution from surface runoff and is best avoided for 48 hours. Further information can be found on www.beaches.ie/protect-your-health-with-the-48-hour-rule/

To whom do I report pollution such as: fish kill; forest fire; oil spillage?
Pollution incidents should be reported in the first instance to the local authority in whose area the incident occurred as they can respond rapidly. The Local Authority will contact the Environmental Protection Agency if an EPA licensed activity is concerned.
If you know it is an EPA licensed activity you should contact the EPA directly as well as the Local Authority.

Microplastics - do they have an impact on water quality?
Microplastics are a newly identified contaminant in water sources, including drinking water sources, across the world. Microplastics are very tiny (<5 mm) pieces of plastic which can come from a variety of different materials.
As microplastics are an emerging water quality issue, the impact of them on people’s health has not yet been fully assessed and determined. There is currently no water quality standard for microplastics in the Drinking Water Regulations. However, the EPA is keeping a close eye on European and Irish research in this area, and there may be a standard set in the future.
