Wyoming Residents Reminded: Test and Maintain Your Private Wells
The Wyoming Department of Environmental Quality is encouraging residents who rely on private wells to take a closer look at their water systems as part of National Groundwater Awareness Week.
Friday, March 13, has been designated “Know Your Well Day,” an initiative aimed at educating the thousands of Wyoming residents who depend on private wells for their drinking water. Officials say the goal is to remind homeowners to regularly “test, tend, and treat” their wells to ensure their water is safe.
Unlike public water systems, the quality of water in private wells is not regulated by state or federal agencies. That means the responsibility for monitoring water safety falls on the well owner.
“Because private well owners are responsible for their own water quality, routine testing is the most reliable way to ensure a safe water supply,” said Wylee Rizzitello, who helps oversee the state’s Know Your Well program.
State officials recommend private well owners test their water at least once a year for bacteria and nitrates. Additional testing may be needed if water changes in taste, odor, or appearance, or after events like flooding or system repairs.
Homeowners are also encouraged to inspect their wells regularly, making sure caps are secure and that the area around the wellhead is free from potential contaminants such as fertilizers, pesticides, or motor oil.
If testing reveals contaminants, WDEQ recommends working with a certified professional to install an appropriate water treatment system.
To help residents maintain their wells, the agency provides educational resources, including fact sheets and instructional videos on collecting water samples. Find more info here.
Weirdest Creatures in the Cowboy State
Wyoming’s animals are wild and weird. Pronghorns rocket across the plains, bison casually block roads, and sage grouse strut around like they own the place. Coyotes, eagles, and mountain lions pop up out of nowhere, making it feel like the state is one big, unpredictable wildlife show.

Wyoming authorities call on Rocky Mountain Power to explain role in massive November power outage
by Dustin Bleizeffer, WyoFile
The massive, multiple-utility power outage last fall that left some 250,000 customers across parts of Wyoming, South Dakota and Montana without electricity was the result of miscommunication and inadequate procedures during planned maintenance that required de-energizing a power line in southcentral Wyoming, according to a report.
The Nov. 13 incident left thousands of homes and businesses without power for 9.5 hours — longer, in some cases — and knocked out a coal-powered generator outside Glenrock. The unit at the Dave Johnston Power Plant remains offline, leaving Rocky Mountain Power to backfill some 300 megawatts of electricity — enough to power about 225,000 homes.
Without expressly assigning blame to any one party, the report — conducted by the Western Electricity Coordinating Council and the North American Electric Reliability Corporation — indicates a series of communication breakdowns between PacifiCorp (parent company of Rocky Mountain Power), the Western Area Power Administration and, to some degree, electrical grid coordinating teams.
While it’s unclear whether authorities such as the North American Electric Reliability Corporation might pinpoint fault and assess penalties, the Wyoming Public Service Commission has called on Rocky Mountain Power to appear at a hearing scheduled for 2:30 p.m. Wednesday. The commission wants to hear from the utility about “the specifics and details of the event and report,” a public notice announced, and it “may consider and take any action that is in the public interest.”
The hearing at the Public Service Commission’s office located at 2515 Warren Avenue, Suite 300, in Cheyenne, will also be livestreamed at this link.
What happened
According to the 49-page report published in June, PacifiCorp and the Western Area Power Administration were coordinating maintenance on their respective systems that, together, required temporarily de-energizing PacifiCorp’s Aeolus–Clover 500 kilovolt line, which runs east-west and is anchored, in part, by a substation near Medicine Bow.
The effort also required curtailing some local wind energy from feeding the grid, according to the report. But on the day of the planned maintenance, Nov. 13, there was confusion about whether the Western Area Power Administration would scrap its work, so wind energy wasn’t curtailed as originally planned.

The report indicates that modeling tools might have failed to accurately measure local grid conditions, so when the power line was de-energized, “power flow rapidly redistributed throughout the northeast portion” of the local grid. “Within six seconds,” according to the report, “an electrical island formed and collapsed, causing widespread effects across that portion of the interconnection.
“The disturbance,” the report continues, “culminated in the loss of more than 4,800 [megawatts] of generation from coal, natural gas, photovoltaic and wind resources.”
The cascading power failure began at about 12:45 p.m. on a Thursday, dragging down portions of service territories operated by Rocky Mountain Power, Black Hills Energy, Montana-Dakota Utilities and some rural electric co-ops.
The report points to failures in communication, process deficiencies and inadequate modeling tools. Wind energy was not “identified as a contributing factor,” according to the report. It credits both battery storage and wind energy throughout the impacted area for supporting “a faster frequency recovery across the interconnection” and for providing “readily available capacity during system restoration.”
