The Colorado 2020 PFAS Sampling Project results were recently released publicly
The results of the Colorado 2020 PFAS Sampling Project were recently released publicly on Tuesday.
The sampling included 152 groundwater sources and 71 surface water sources, including rivers and streams. The project covered about half of the drinking water systems in the state, which serves 75% of the population, according to a press release from the Colorado Department of Public Health and Environment.
According to the results, there were no drinking water systems or fire station districts in the State of Colorado with PFAS levels above the EPA's health advisory.
There were four entities that tested source water had sample results that exceeded the EPA health advisory, reported the study. Three of the four already tested for the chemicals in previous years and have notified the public of those results. These were: Stratmoor Hills Water and Sanitation District and Security Water and Sanitation District of El Paso County and Sugarloaf fire district of Boulder County. The fourth entity is Fourmile Fire District.
The three entities are either not using that source water or treating the water to remove the chemicals before using it as drinking water, according to the study.
Fourmile Fire District had not previously tested for the chemicals and found high levels in a well at one of their stations, reported the study. The firefighters do not drink this well water, however, according to state authorities, but the area is being examined to determine whether residents living nearby may be impacted.
“The current results show that no drinking water tested above the EPA health advisory for two chemicals,” said Kristy Richardson, state toxicologist at the Department of Public Health and Environment. “At the same time, we know science is evolving, and we are committed to using the most current and best available information to provide health-based guidance on exposure to the chemicals. As new studies become available, our understanding of health effects in humans -- and our recommendations -- will continue to be refined.”
