Study shows that many household wells need better drinking water treatment and monitoring Outside of Nevada’s bustling cities, private wells are the primary source of drinking water, serving 182,000 people. Yet some of the tested private wells in Nevada are contaminated with levels of heavy metals that exceed federal, state or health-based guidelines, a new study published in Science of The Total Environment shows. Consuming water contaminated by metals such as arsenic can cause adverse health effects. Scientists from DRI and the University of Hawaii Cancer Center recruited households with private wells through the Healthy Nevada Project. Households were sent free water testing kits, and participants were notified of their water quality results and recommended actions they could take. More than 170 households participated in the research, with the majority from Northern Nevada around Reno, Carson City and Fallon. “The goals of the Healthy Nevada project are to understand how genetics, environment, social factors, and healthcare interact. We directly engaged our participants to better understand environmental contaminants that may cause adverse health outcomes,” said co-author Joseph Grzymski, PhD, research professor at DRI, principal investigator of the Healthy Nevada Project®, and chief scientific officer for Renown Health. Nearly one-quarter (22%) of the private wells sampled had arsenic that exceeded safe levels determined by the Environmental Protection Agency (EPA) — with levels 80 times higher than the limit in some cases. Elevated levels of uranium, lead, cadmium, and iron were also found. “We know from previous research that Nevada’s arid climate and geologic landscape produce these heavy metals in our groundwater,” says Monica Arienzo, PhD, an associate research professor at DRI who led the study. “It was important for us to reach out to community members with private wells to see how this is impacting the safety of their drinking water.” Fewer than half (41%) of the wells sampled used water treatment systems, and some treated water samples still contained arsenic levels over EPA guidelines. Although average levels of heavy metal contaminants were lower in treated water, many homes were unable to reduce contaminants to levels considered safe. The state leaves private well owners responsible for monitoring their own water quality, and well water testing helps ensure water is safe to drink. This study shows that more frequent testing is needed to ensure Nevada’s rural communities have safe drinking water. This is particularly important as the effects of climate change and population growth alter the chemistry of groundwater, potentially increasing metal concentrations. “The results emphasize the importance of regular water quality monitoring and treatment systems,” said co-author Daniel Saftner, MS, assistant research scientist at DRI. Although the research focused on wells in Nevada, other arid communities in Western states are facing similar risks of water contamination.

The American Heart Association presents Get With The Guidelines®- Stroke Gold Plus awards for proven dedication to ensuring all stroke patients have access to best practices and life-saving care. Renown Health emergency, medical and surgical providers have received three American Heart Association’s Get With The Guidelines® awards. These awards demonstrate commitment to ensuring stroke patients receive the most appropriate treatments according to nationally recognized, research-based guidelines; reducing disabilities and increasing the number of lives saved. Every 40 seconds, someone in the U.S. has a stroke. Los derrames cerebrales son la quinta causa principal de muerte en los EE. UU. y la principal causa de discapacidades en adultos. Studies show patients recover better when providers consistently follow treatment guidelines. Get With The Guidelines puts the expertise of the American Heart Association and American Stroke Association to work for hospitals nationwide, helping ensure patient care is aligned with the latest research and evidence-based guidelines. “A stroke is an extremely serious condition that requires emergent medical treatment. The faster treatment is provided, the lower the risk of brain injury. We are proud of our thousands of physicians, nurses and clinicians who consistently practice exceptional patient care by adhering to the latest treatment guidelines,” said Brian Erling, MD, MBA, President and CEO, Renown Health. “Get With The Guidelines makes it easier for our teams to put proven knowledge and consistent protocols to work on a daily basis, which studies show can help people live longer and better lives.” “As a participant in Get With The Guidelines programs, Renown qualified for the awards by demonstrating that physicians and clinicians across our integrated health system are committed to improving quality care for stroke patients,” said Bill Plauth, MD, MMM, CPE, Chief Medical Officer for Renown Health and Associate Dean for Clinical Affairs at the University of Nevada, Reno School of Medicine. “If you or a loved one is experiencing a stroke, call 911, as you need skilled medical care immediately. Stroke care focuses on helping people recover as much function as possible and return to independent living. The Renown Neurovascular and Stroke Program and Renown Rehabilitation Hospital teams provide expert emergency stroke care and comprehensive neurovascular care and rehabilitation services.” “We are pleased to recognize Renown Health for its commitment to caring for those in their community who need cardiovascular care,” said John Warner, MD, FAHA, past president of the American Heart Association and CEO of The Ohio State University Wexner Medical Center. “Hospitals that follow the American Heart Association’s quality improvement protocols often see improved patient outcomes, fewer readmissions and lower mortality rates – a win for health care systems, families and communities.” “Renown Regional Medical Center is the only designated Comprehensive Stroke Center in northern Nevada,” says Benjamin Pence, DO, Director, Institute for Neurosciences at Renown. “This means that we have the highest level of certification to receive and treat the most complex stroke cases. Our Institute for Neurosciences team is led by the area's top neurologists, and we conduct research studies involving new ways of preventing, diagnosing, and managing neurological disorders. We care for patients suffering from nerve and brain disorders due to stroke, headache, epilepsy, and other acute causes. We also monitor and develop treatment options for patients with memory and movement disorders such as Alzheimer’s, Parkinson's Disease or Multiple Sclerosis.” Renown Health also received the American Heart Association’s Target: Stroke Honor Roll Elite award. To qualify for this recognition, hospitals must meet specific criteria that reduce the time between an eligible patient’s arrival at the hospital (within 60 minutes or less) and treatment for at least 85 percent of applicable patients. “It is an honor to be among the American Heart Association’s Stroke Honor Roll Elite award recipients,” said Bret Frey, MD, president of Northern Nevada Emergency Physicians Care teams at Renown Health. “We adhere to these rigorous guidelines daily and demonstrate our unwavering commitment to ensuring more people in northern Nevada receive leading emergency and trauma care and the gift of extended, healthier lives.” Renown Health also received the American Heart Association’s Target: Type 2 Diabetes Honor Roll - Stroke award. Target: Type 2 Diabetes aims to ensure patients with Type 2 diabetes, who might be at higher risk for complications, receive the most up-to-date, evidence-based care when hospitalized due to stroke. This award is given to hospitals that qualify for the silver level or higher achievement award within the Get With The Guidelines – Stroke program and achieve an overall Diabetes Cardiovascular Initiative Composite Score of more than 80 percent.
