Drinking Water Lab Reports

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

Summit Environmental Tech

Full Service lab DW certified by Ohio

EPA DW certified by most

states DOD certified

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

MUST BE OHIO EPA CERTIFIED

Full service lab Want the lab to sample Lab that had been in

business for awhile

ODNR recommends testing for..

Tier 1 Tier 2 Tier 3 Barium

Chloride Magnesium Potassium Sodium

Strontium Sulfate

Total Dissolved Solids

Total Alkalinity pH

Tier 1 parameters plus

Calcium Hardness

Iron Manganese

Specific Conductivity

Total Suspended Solids

Bromide

Tier 1 & 2 plus Dissolved Methane BTEX

(benzene, toluene, xylene, ethylbenzene)

In addition we recommend

Radiological– Gross alpha– Radium 228– Radium 226– Uranium– Gross beta

Ethylene glycol

Units of measurement

mg/l milligrams per liter or ppm part per million

ug/l micrograms per liter or ppb parts per billion

What lab report includes

Title page Sample summary Report/case narrative Results

Chain of Custody

Reading the actual report

Client ID# Lab ID# Collected Analyte

Well head 1126627-01 9/14/11 bromide

Client ID#: What the sample was called on Chain of custody

Lab ID#: How the lab identifies the sample in house

Collected: What date the sample was collected

Analyte: what test is being preformed

Result Units Matrix Method DF LOQ Run Analyst

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 are compounds added to ensure the analysis is working correctly.

They appear in BTEX testing on the report The compounds are

1. Dibromoflourometane

2. Toluene-d8

3. Bromofluorobenzene
