Drinking Water Lab Reports

Unveiling the who, what, and how of drinking water testing

summit environmental tech
Summit Environmental Tech
  • Full Service lab
  • DW certified by Ohio EPA
  • DW certified by most states
  • DOD certified
why have your water tested
Why have your water tested?

According to the EPA 80-85% flowback water is trapped underground and has the potential to seep into wells and aquifers.

  • Have a background of what’s going on with your water.
  • Recommend to have your water tested more than once. Ideally quarterly
  • Be proactive incase someday there is a problem
choosing a lab
Choosing a Lab
  • MUST BE OHIO EPA CERTIFIED

ResultUnitsMatrixMethodDFLOQRunAnalyst

ND mg/l L 300.0 1 0.5 9/17/11 KMG

Result: ND stands for non-detect or there could be a number such as 1.0

Units: How the result is measured

Matrix: for drinking water will always be L for liquid

Method: which EPA method was used for testing

LOQ: how low the lab will report also can be called RL (reporting limit)

RUN: when the sample was analyzed

Analyst: the initials of the person who preformed the test

surrogates
Surrogates
  • Surrogates are compounds added to ensure the analysis is working correctly.
  • They appear in BTEX testing on the report
  • The compounds are
    • Dibromoflourometane
    • Toluene-d8
    • Bromofluorobenzene
