Drinking water certified laboratory reporting forms
Instructions for reporting potential acute situations: Positive coliform, positive E. coli, high nitrate, high nitrite, surface water residual or turbidity, chlorine dioxide or chlorite.
Please do not submit SAMPLE RESULTS as a PDF or Excel file. We are moving away from having drinking water sample results submitted as a PDF or Excel file (except for MORs, daily chlorite/chlorine dioxide, water quality parameters, and additional lead and copper samples not part of your sampling pool) in order to improve data quality (i.e., reduce manual data entry errors), reduce duplicate data submissions (this slows down our data processing), have faster transfer to our EPA data system, and have faster updates to the online monitoring schedules. Samples are required to be analyzed by a certified laboratory using a certified method.
Please do not submit PDF/Excel files for sample results into the portal, unless specifically requested by the Department. Please note that you are still able to submit PDF files for routine correspondence (e.g., public notice, monitoring plans, certificate of delivery, etc.). Thanks in advance for helping us improve data quality and efficiency, which in turn help us all best protect public health!
Public water systems:
- Please make sure you are providing this information to the lab if they are reporting the data on your behalf. The following information is required:
- If the lab is submitting on your behalf then do not submit sample results as this results in duplicate data submissions.
- When the lab submits the CSV file you will be able to see your public water system’s sample results 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 you choose to report the results you received from a certified laboratory please follow the CSV Forms and Instructions below to create a system specific CSV form.
Certified laboratories submitting the results on the behalf of systems:
- Please make sure you are receiving the required information above from the system on your chain of custody form.
- Pursuant to Colorado’s Laboratory Certification Program, since you are a certified laboratory, please be aware that your certification requires your laboratory to submit drinking water data as a CSV file to CDPHE.
- If you have questions on creating a CSV or need a CSV template please contact the data group.
