Accredited water testing for oil and gas compliance
NELAP/TNI and ISO/IEC 17025:2017 accredited for nonpotable water, with geochemists who can interpret your results when a number raises questions. One lab, one chain of custody, and a submittal-ready deliverable.

Choose your state
Find the requirements and testing for your state’s rule
Each state page covers the rule’s schedule and analyte list, what DIG runs for it, the deliverable, and how to order sampling kits.
Colorado
ECMC Rule 615
Life-of-well baseline and monitoring. Every groundwater report includes an ECMC electronic data deliverable (EDD) and interpretive plots.
Wyoming
WOGCC Rule 3-46
Baseline and two post-casing sampling rounds, with a 24-hour notification duty when results cross a trigger.
New Mexico
20.6.8 NMAC
Produced water pilot projects: characterization and monthly water-quality reporting for up to five years.
How it works
From sampling kit to a submittal-ready report
01
Order kits
Tell us your state, the rule, and the number of locations. Kits are provided with your order: pre-preserved bottles, instructions, and a chain-of-custody form.
02
Sample and complete the COC
Follow the sampling guide for your matrix. Field parameters your rule requires, such as temperature and dissolved oxygen in Wyoming, are measured by the sampler.
03
Ship to our Westminster lab
Samples are received and logged at our Colorado laboratory. Standard turnaround is 10 business days, with Rush (5 business days) and Super Rush (3 business days) available.
04
Receive your report and EDD
The analytical report, the EDD where your rule calls for one, and interpretive plots in Excel. A qualified scientist will walk you through the data on request.
What we test
Water chemistry and gases for oilfield compliance
Choose a standard suite or build one from the full list. The analyses and methods page lists the method for each analyte and whether it is within our accreditation scope.
| Group | Analytes |
|---|---|
| General chemistry | pH, specific conductance, total dissolved solids, total suspended solids, alkalinity |
| Major cations and metals | Calcium, magnesium, potassium, sodium, barium, boron, iron, lithium, manganese, selenium, strontium, and others |
| Anions | Bromide, chloride, fluoride, nitrate, nitrite, phosphate, sulfate |
| Organics | BTEX, gasoline range organics, diesel range organics |
| Dissolved gases | Methane, ethane, propane (RSK-175) |
| Isotopes | δ¹³C and δ²H of methane and ethane; δ²H and δ¹⁸O of water; δ¹³C of dissolved inorganic carbon |
Accredited methods and matrices are listed in our current scope of accreditation on the Accreditations page.
Beyond compliance
When a result needs explaining, talk to a geochemist
Most compliance labs stop at the number. When dissolved methane crosses your state’s trigger, DIG can run compositional and stable isotope analysis on the same sample and interpret it against more than 30 calibrated North American basin models. Our geochemists also support bradenhead and surface casing pressure investigations.
