Compliance Monitoring Data Portal (CMDP)

Revised On: Dec. 16th, 2024 - 03:29 pm

ADEQ is streamlining the reporting process and improving data accuracy by requiring all public water systems to submit water quality compliance data through the Compliance Monitoring Data Portal (CMDP). Starting in 2025, Arizona systems will stop using Drinking Water Analysis Reporting (DWAR) forms for results in the following section labeled “Results accepted in CMDP”: 

Results ACCEPTED in CMDP

* Please note this list may expand in the future

Bromate (Disinfection Byproducts)

Chlorite (Disinfection Byproducts)

Inorganic Compounds (IOCs)

Lead and Copper (LCR) 

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS)

Radionuclides (RADs)

Synthetic Organic Compounds (SOCs)

Total Coliform and E. coli (RTCR)

Total Trihalomethane and Haloacetic Acids
(Disinfection Byproducts)

Volatile Organic Compounds (VOCs)

Water Quality Parameters (WQP)

Results NOT ACCEPTED in CMDP

* Please note this list may expand in the future

About CMDP 

CMDP is the Environmental Protection Agency’s (EPA’s) online portal used by state agencies nationwide to meet Safe Drinking Water Act reporting requirements and related Arizona drinking water rules. The online portal:

  • allows for quick and efficient compliance data submittal to ADEQ,
  • reduces paperwork, manual effort and potential for human error, and
  • introduces programmed quality assurance checks that allow quick troubleshooting of data discrepancies before submission. 

Users can include:

  • Labs
  • Public water system owners
  • Public water system staff
  • Operators

Public water system owners or operators can set up CMDP accounts to submit compliance data to ADEQ or delegate to labs. Because CMDP does not replace the chain of custody requirements or a lab’s obligation to report results to public water systems, ADEQ encourages public water systems to work with their laboratories to develop a reporting process using CMDP. Lab submittals can streamline the process and minimize potential data errors.

ADEQ requires written permission from a public water system owner for any individual user to submit data on the public water system’s behalf. The owner must verify the individual user’s role in submitting data in the CMDP application before uploading results.

The Arizona Safe Drinking Water Information System (AZSDWIS), also known as Drinking Water Watch, allows tracking of results uploaded through CMDP. Submitted results will appear in AZSDWIS within 20 minutes after being uploaded | View AZSDWIS > 

How to Get Started:

Email ADEQ’s CMDP team to get an account | Request Account > 

Note: If you represent a public water system, please determine whether your lab will upload results for you.  

Once ADEQ receives your email, we will begin creating test CMDP accounts.

Once the test accounts are finalized, ADEQ will schedule a time to demonstrate the CMDP process with you.

You must complete test uploads to ensure you can submit accurate information without errors. 

Once tests are successfully uploaded, ADEQ will begin creating your official account.

If you are a CMDP certifier or CMDP administrator for your organization, you must sign the ADEQ Electronic Signature Agreement before your account can be approved |  Agreement Form > 

 

  • Accurate Chain of Custody forms ensure timely results are uploaded. Chains of Custody for compliance samples must include the following:
    • The correct public water system name, ID, and sampling location.
    • Accurate sample collection date and time.
    • An indication that the sample is for compliance when submitted to the laboratory. 
      Note: Chains of Custody not marked for compliance cannot be used for compliance purposes by ADEQ and cannot be changed by the laboratory. The only minor data adjustments the laboratory may make are location clarifications (e.g., if the system has only one EPDS numbered EPDS001 and the EPDS was documented as EPDS100). The public water system is responsible for ensuring that information is submitted correctly to the laboratory.
  • Public water systems must continue to notify ADEQ of any total coliform-positive samples, E. coli-positive samples, and MCL exceedances within 24 hours of being notified about the issue, even if the lab is designated as the primary reporting entity. They should also continue to inform their Compliance Assistance Coordinator of any exceedance. 
  • ADEQ encourages public water systems to work closely with their designated laboratory to ensure accurate and timely data submission when the laboratory serves as the primary uploader. While laboratories play a critical role in the process, public water systems are ultimately responsible for compliance. If monitoring deadlines are missed, resulting violations are issued to the public water system, regardless of the circumstances surrounding the submission.
  • ADEQ highly recommends documenting and frequently reviewing the responsibilities of all parties involved in the reporting process. ADEQ is not responsible for establishing agreements or designating role responsibilities amongst these parties.
  • These changes do not affect any lab-maintained results databases for customers, and results, if applicable, will still appear there first.
