Nutrient testing for water treatment and environmental monitoring

Laboratories of Eurofins Water Hygiene Testing are able to assess the composition of targeted nutrients present in water across a wide variety of applications and sample matrix types.

Why nutrient testing matters

Nutrient testing is essential for understanding the chemical composition of water and its potential to support microbial growth, algal blooms or eutrophication. Commonly measured nutrients include nitrate, nitrite, ammonia, chloride, fluoride and phosphate. Elevated nutrient levels can indicate pollution, dosing imbalance or organic loading, affecting both water quality and system performance. Routine monitoring is important in industrial and environmental applications to maintain control and demonstrate compliance.

Supporting system balance, water quality and environmental responsibility

In closed heating and cooling systems, nutrient imbalance can encourage bacterial growth and biofilm development. In environmental settings, nutrient pollution from runoff, effluent or agriculture can degrade natural waters and breach discharge or abstraction limits. Whether you manage potable water, process systems, wastewater or surface waters, nutrient testing provides essential information for system health, treatment optimisation and environmental protection.

Testing and methods

Eurofins water hygiene testing provides high-precision analysis of key nutrients using colorimetric, segmented flow and ion chromatography techniques. We routinely test for:

  • Ammonia
  • Nitrate
  • Nitrite
  • Phosphate
  • Orthophosphate
  • Total oxidised nitrogen (TON)
  • Chloride
  • Sulphate
  • Fluoride

Typical turnaround times are three to five working days, depending on sample type and parameters requested. Testing is performed in UKAS-accredited laboratories with matrix-specific accreditation. For additional analytes, we work with approved subcontractors, including Eurofins European competence centre partners, to extend our testing scope.
