waste water

Water – groundwater, surface waters, wastewaters and effluents

Waters are sampled from a wide variety of sources, but any discharges must comply with discharge consent limits, set by the Environment Agency.  DETS can provide a wide range of tests for routine monitoring, site characterisation, or contamination to water courses.  This can include a range of parameters included in the JAGDAG list of potential contaminants. Again, accreditation applies across a range of matrices including:

  • Trade effluent
  • Landfill leachates
  • Ground and surface waters
  • Process waters

 Commonly requested parameters include:

  • Toxic metals – , Cu, Cr, Hg, Ni, Pb, Zn, Fe, Al, Be, As, B, etc.
  • Major cations– Na, K, Ca, Mg
  • pH and electrical conductivity
  • BOD – biochemical oxygen demand
  • COD – chemical oxygen demand
  • Anions – Cl, NO3, NO2, SO4, PO4
  • Ammoniacal nitrogen – free ammonia, ammonium
  • Cyanides – Total, Free (easily liberatable), Thiocyanate
  • OFG – oils, fats and greases
  • Alkalinity – carbonate and bicarbonate
  • Hardness
  • Solids – total suspended solids, total dissolved solids, total solids
  • TOC – total organic carbon
  • VOCs – volatile organic compounds
  • SVOCs – semivolatile organic compounds
  • TPH – GRO, EPH, speciated TPH, BTEX
  • PAHs – polyaromatic hydrocarbons
  • PCBs – polychlorinated biphenyls
  • Pesticides & herbicides – chlorinated, phosphorylated, triazines


DETS provide suitable sample containers, including appropriate preservatives as specified in BS ISO 5667, for the sampling of all water matrices for clients to take their own samples. DETS is also accredited for sampling, including MCERTS accreditation for sampling for discharge to sewer, should this service be required, and a courier service is also available.
