Wastewater & Effluents


We have decades of experience testing sewages, wastewaters & trade effluents for regulatory compliance.

Analysis is conducted to MCERTS and UKAS standards at our Howdon laboratory. We hold UKAS / ISO 17025 accreditation for the following wastewater & effluent types:

  • Untreated sewages
  • Treated sewage effluents
  • Trade effluents

    Northumbrian Water Scientific Services (NWSS) can help design sample programmes with integral samples points and specific discharge consent values to meet your legislative needs. Our UKAS & MCERTS accredited analysis includes:

  • BOD, COD, suspended solids, pH, oil & grease
  • Dissolved oxygen
  • NH4, NO3, NO2
  • Anionic and non-ionic detergents
  • Metals
  • An extensive range of organics (VOC′s, SVOC′s, pesticides and herbicides)

    We can also offer fast turnaround analysis and electronic data transfer reporting for sample programmes.
