Drinking Water Bureau

Welcome to the Drinking Water Bureau of the New Mexico Environment Department

Our mission is to preserve, protect and improve New Mexico’s drinking water quality for present and future generations.

In support of this mission, Drinking Water Bureau (DWB) regulates water quality at public water systems in New Mexico.  A public water system is any water system that serves at least 15 service connections or 25 individuals at least 60 days out of the year.

DWB ensures public water systems provide drinking water that meets all regulations by:

  • Overseeing water system compliance with the Safe Drinking Water Act and New Mexico drinking water regulations
  • Providing technical, managerial and financial assistance to water systems

October 9, 2020

The New Mexico Environment Department’s Drinking Water Bureau (DWB) is taking this opportunity to provide you with information about an important change to drinking water contaminant compliance sampling payments during calendar year 2021.

This announcement serves as NMED’s notification to your public water system of the contaminant analyses that will not be paid for by the Water Conservation Fund (WCF) during calendar year 2021. Because of several sustained years of decreased revenues into the WCF and increased program expenses, NMED must eliminate payments for sample analysis of the following contaminants during calendar year 2021 (January 1 – December 31, 2021):

  • Disinfection Byproducts (DBPs)
    • Total Trihalomethanes (TTHM)
    • Haloacetic Acids (HAA5)
  • Asbestos

NMED is committed to supporting public water systems and minimizing the financial burden to already strained local government and water utility budgets. NMED continues to explore additional sources of funding to supplement the WCF balance and enable the WCF to continue payments for these samples in 2021. If additional funding is secured prior to January 1, 2021 that enables the WCF to continue the payment of these samples, we will promptly notify you in a separate letter. However, we strongly advise your public water system to begin planning now for the expenses associated with meeting your system’s compliance obligations in calendar year 2021 in accordance with this notification.

In addition to our focus on WCF coverage in 2021, NMED is working hard to address other factors affecting revenue and expenditures, and will continue to work closely with the Taxation and Revenue Department to address noncompliant public water systems who are not paying the required Water Conservation Fund fee. This will ensure the WCF is solvent for years to come, with limited to no reduction in services.

If your water system needs assistance with planning and budgeting for the collection and analysis of Disinfection Byproducts or Asbestos samples for calendar year 2021, the DWB Community Services Team can provide that assistance to your water system. For Community Services Team contact information please visit:

Recent Water Advisories

    • Loma Escondida Water Association (October 2, 2020) – The New Mexico Environment Department’s (NMED) Drinking Water Bureau (DWB) issued a precautionary advisory on behalf of the Loma Escondida Water Association. Due to a recent water outage, NMED is advising water consumers of the Loma Escondida Water Association to use bottled water for all drinking (including baby formula and juice), brushing teeth, washing dishes, making ice, and food preparation.
    • El Vadito De Los Cerrillos (September 1, 2018) – A boil water advisory was required to be issued by the water system on September 1, 2018 following confirmation of E. Coli-positive samples from the water system’s distribution system.
    • Bug Scuffle Sportsman’s Ranch (December 4, 2017) – Boil water advisory was required to be issued by the water system on December 4, 2017 after the system failed to collect the required repeat samples within the required time-frames following an E. Coli-positive routine sample from the water system’s distribution system.


Consumer Confidence Report Information

The New Mexico Environment Department’s Drinking Water Bureau (NMED DWB) has prepared a reminder notification for the 2019 Consumer Confidence Report (CCR).  The 2019 CCR must be prepared and distributed to the NMED DWB as well as the public water system’s consumers no later than July 1, 2020.  The CCR Rules requires all community water systems to prepare and distribute a brief annual water quality report summarizing information regarding source water, detected contaminants, compliance, and educational information.  The 2019 NMED DWB CCR reminder notification can be viewed here (2019 CCR Reminder Notification).


Asbestos Sampling Waiver Information

The New Mexico Environment Department has begun the process of determining Asbestos waivers for the 2020-2022 monitoring period and is requesting assistance from public water systems to determine whether any part of your drinking water system contains Asbestos Cement (“TransiteTM”) piping.  Accurate and timely responses for this survey are very important because this survey could affect asbestos sampling waivers, which are based, in part, upon the results of this survey.  Failure to complete and return this survey will result in your system being required to collect asbestos samples.  Please download and complete the form in the link below and return it to the Drinking Water Bureau Sampling Waiver Coordinator (Tim Willy) as soon as possible . If you have any questions regarding these waivers, please feel free to call Please contact Tim Willy  at (575) 762-3728 or by email at .

Required Chain-of-Custody Sample Forms

Beginning January 1, 2019, Total Coliform (TC) laboratories must begin utilizing a new mandatory Chain-of-Custody (COC) for submission of all microbiological samples for public water systems in New Mexico.  This new COC is designed to meet the minimum sampling requirements for the Ground Water Rule (GWR), Revised Total Coliform Rule (RTCR) and the LT2 rules.  A sample of the new form and instructions for filling out the form can be downloaded here.  New Sample Chain-of-Custody (COC) Form
