Water and Wastewater Analysis

Expert Chemical Analysis uses water analysis methods that conform to the U.S. Environmental Protection Agency (EPA), or Standard Methods for Examination of Water and Wastewater (APHA). Other methods may be utilized upon customer’s request of where special conditions exist.

Notes:

  • Materials more radioactive than natural Th and natural U will not be analyzed.
  • Cs and I are difficult to analyze by ICP or GFAA. Alternate methods may be used.

Individual Organic Compounds in Waters and Wastewater:

ECA performs primarily specialty organic analysis in water and wastewater. using modified EPA methods or methods developed specifically for the analytes in question. Note: As part of our expansion, ECA is in the process of becoming certified in volatile and semivolatile organic analysis of water and wastewater. We expect to be finished with this process in the early part of 2004.

Some tests we currently perform are mentioned below:

  • Ethylene Glycol in Water or Wastewater/GC-FID
  • Propylene Glycol in Water or Wastewater/GC-FID
  • Dimethylformamide in Water or Wastewater/GC-FID/GC-MS
  • Formaldehyde in Water or Wastewater/HPLC/UV-Vis
  • Sulfolane in Water/GC-MS
  • Triethylamine and Pyridine in Water/GC-FID
  • Many other examples available, please call with your requirements.
