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

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 Tim.Willy@state.nm.us .

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
