Ireland’s Rivers See Rising Nitrogen in Early 2025 – Some Concern After Previous Declines
The EPA’s latest Early Insights: Nitrogen Concentration Indicator – January to June 2025 report, published in September, brings a note of caution: nitrogen concentrations in Irish rivers rose by around 16% compared with the same period in 2024. While this is only a six-month snapshot, it suggests that the downward trend highlighted last year may have stalled or reversed.
Award-winning Irish water tech company, Aquamonitrix announces Colm Lynch as new CEO

Chloramines & Nitrification : Aquamonitrix® Allows for Timely Intervention to Avoid Drinking Water Problems
Choramines and nitrification: Aquamonitrix® is being used in the US by water-utilities to control nitrification (nitrite-formation) in chloraminated drinking-water supplies. Aquamonitrix® is a next-generation autonomous, real-time nitrite and nitrate analyzer that can...
Technical Note for the ASP / FE monitoring towards N2O emission risk understanding and process control
Removal of ammonia is a primary aim of wastewater treatment processes. The chemistry and biology of the process is well understood. In summary, it involves a nitrification step in which ammonia is firstly converted to nitrite and then nitrate followed by a...
The salinity challenge when measuring nitrite and nitrate in RAS
When considering the application of real-time monitoring of nitrite and nitrate in recirculating aquaculture systems, varying salinity is a major consideration. Fully saline RAS are common and represent a significant portion of RAS globally. In addition, within...
