Facts & Tips

New Staff Roles

New staff and/or new roles will be posted here occasionally. For a complete list of all the EPA Region 8 staff and their current roles/responsibilities please see the EPA Region 8 Drinking Water Unit Contact List.

Changes to SOC Monitoring Requirements

For several years EPA had not required Wyoming and Tribal water systems to sample for the 5 Synthetic Organic Chemicals (SOCs) Endothall, Diquat, Glyphosate, 1,2-Dibromo-3-chloropropane (DBCP), and 1,2-Dibromoethane (Ethylene Dibromide (EDB)). After an evaluation of this practice, EPA is now requiring all community and non-transient non-community water systems to sample for the complete set of SOCs that are listed in the drinking water regulations at 40 C.F.R. 141.24 with the exception of dioxin and total PCBs, which EPA is still evaluating.

Drinking Water Guide For Small Business Owners in Wyoming

If your business or facility makes water available to the public by providing food, drinks, restrooms or lodging, then you are likely managing a public water system that must meet certain safety requirements according to the Safe Drinking Water Act. If you would like to find out more, please see Drinking Water Guide For Small Business Owners in Wyoming.

Some SDWIS Data Now Available to the Public

Compliance and enforcement data from the State Drinking Water Information System (SDWIS) for drinking water systems is now available to the public through the Envirofacts SDWIS Search.

Sanitary Surveys

For information about questions we may ask during Sanitary Surveys this year, please review either the Wyoming Sanitary Survey Template or the Tribal Sanitary Survey Checklist/Template on the Reporting Forms page. We have also posted the slides from presentations on Sanitary Surveys in the Training Presentations section.

Latest News

Climate Change and Water

Climate change is changing our assumptions about water resources. As climate change warms the atmosphere and alters the hydrological cycle, we will continue to witness changes to the amount, timing, form, and intensity of precipitation and the flow of water in watersheds, as well as the quality of aquatic and marine environments. These changes are also likely to affect the programs designed to protect the quality of water resources and public health and safety. To learn more, please visit Addressing Climate Change in the Water Sector.

Hydraulic Fracturing (or Fracking)

You have probably noticed there has been a great deal of public interest and media attention lately regarding hydraulic fracturing (or fracking). To find out more about what EPA is doing, please visit EPA's Study of Hydraulic Fracturing and Its Potential Impact on Drinking Water Resources.

Deadly Brain Amoeba Infects US Tap Water

News agencies worldwide are carrying stories about the presence of Naegleria fowleri, commonly referred to as a brain-eating amoeba, in a New Orleans area water system. The contaminant is believed to be the culprit in the recent death of a four-year-old boy infected after playing on a slip-n-slide.

EPA’s Office of Research and Development indicates that Naegleria fowleri has been known since the 1970’s when it caused infections in people in Perth, Australia as a result of the drinking water being very warm and the chlorine residual levels being very low. It is controlled by keeping the chlorine residual (free chlorine or total chlorine (if you use chloramines)) in the distribution system greater than 0.5 mg/L. You cannot be infected by ingestion, it must enter through the nose.

Water utilities should be prepared for media inquiries about the potential for Naegleria fowleri contamination in their systems. Information is provided below to help utilities speak to this issue.

Systems with warm water temperatures who may be concerned about this pathogen should focus on distribution system residual levels, dead ends and a unidirectional flushing program. More information may be found at the following CDC website: Naegleria fowleri and Public Drinking Water Systems

Mail & Reminders

2019 Drinking Water Monitoring Requirements

The 2019 Drinking Water Monitoring Requirements and a copy of the current water system site schematic will be sent (via email or postal mail) to each water system sometime in March. If you do not receive your copy or would like another copy, please let us know.

Drinking Water Watch

Drinking Water Watch is an online tool available to operators, administrators and others involved with public water systems to review monitoring requirements, sampling results and related data, copies of your water system schematic, the latest reminder to sample and report, and sampling forms for use with chemical and radiological samples. It can be useful for many purposes including checking data when away from your office or system and ensuring that the EPA has all your samples and accurate information about your system.

EPA Region 8 is pleased to announce a new version of Drinking Water Watch (DWW) that is accessible to the public without a username or password. Although the information available through this website is somewhat restricted, it includes sample schedules, lab results, violations and enforcement actions and more. Please visit the Public Access Version of DWW and feel free to share this information with anyone else who might be interested.

If you were previously registered for the restricted access version of DWW and have lost your password, or if your password has expired, please contact us for assistance.


One way to track your sampling and reporting requirements is by using the calendar software on your computer. Computer calendars usually allow you to schedule one-time and recurring events easily. You may also set the computer to remind you of a sampling or reporting "event". If you prefer to fill in a paper form and post it on your bulletin board, you may prefer this Sampling Calendar also available in MS Excel format .

New Rules

There are several drinking water rules that have, or may soon, affect requirements for your public water system. We have notified systems regarding changes and any actions they may need to take. For information, please visit New and Revised Rules.

Revised Total Coliform Rule (RTCR)

The Revised Total Coliform Rule (RTCR) is a significant revision to the 1989 Total Coliform Rule (TCR) and is intended to improve public health protection. All public water systems must comply with the RTCR starting in April of 2016. Until then, PWSs must continue complying with the Total Coliform Rule (TCR).

For more information, please visit Revised Total Coliform Rule And Total Coliform Rule.

Reduction of Lead in Drinking Water Act

Congress recently adopted the Reduction of Lead in Drinking Water Act which will amend the SDWA to reduce the national standard of lead in pipes, pipe fittings and plumbing fixtures from 8% to 0.25%. Several states already have standards lower than 8%. The law provides for a 36 month implementation period.

For more information, please visit Use of Lead Free Pipes, Fittings, Fixtures, Solder and Flux for Drinking Water.
