Instructions for reporting potential acute situations: Positive coliform, positive E. coli, high nitrate, high nitrite, surface water residual or turbidity, chlorine dioxide or chlorite.
Public Water Systems
- Please provide the following required information to the lab on the chain of custody if they are reporting the data on your behalf:
- If the lab is submitting please do not submit duplicate sample results.
- Sample results are viewable in the Portal by clicking “My…” in the menu bar and selecting “Sample Results”.
- You can also be automatically notified when results are submitted by the lab in CSV by adding the electronic notification permission for the water system.
- If reporting results from a certified laboratory please follow the CSV Forms and Instructions below to create a system specific CSV form.
Certified laboratories submitting results
- Please make sure to receive the required information from the system on the chain of custody form. This information is listed to the left.
- Pursuant to Colorado’s Laboratory Certification Program, your certification requires submission of drinking water data as a CSV file.
- If updates need to be made please resubmit a revised CSV file.
- If you have questions on creating a CSV or need a CSV template please contact the data group.
- Lab Sample IDs act as a unique identifier for the sample for the bottle and should not be reused unless submitting a revision. Multiple analytes should generally be under the same lab sample ID when analyzed from the sample bottle, same Facility ID, and Sample Point ID. Below is a general list of analytes that share the same Lab Sample ID:
- Coliform and E. coli
- TTHMs (all the individuals and the total)
- HAA5s (all the individuals and the total)
- Lead and Copper
- IOC Group
- SOC Group
- VOC Group
- Radium (individuals and the total)
- Gross alpha and Combine Uranium
Sample result correction
- If updates need to be made please resubmit a revised CSV file or use the correction form (includes updating residuals). Updated CSVs with the same Lab ID, Lab Sample ID, and Analyte are considered revisions. The most recent submission is used.
- If a deletion is needed please send a PDF through the Portal using the Certifications category. The request must include the unique lab sample ID, collection date, analyzing lab, analyte, and the reason for the requested sample to be deleted.
