Arvada Water Quality performs internal sampling. So far there has been no detected PFAS compounds near the EPA reporting limits in our raw or treated waters (see Internal PFAS Results (PDF)). Arvada also participated in Colorado Department of Public Health and Environment's 2020 PFAS Sampling Project. We will also be participating in the EPA's UCMR5 sampling in 2023 which includes many more PFAS compounds than tested for in the past. All of this information will be publicly available when complete.
The City works very hard to keep our drinking water safe for all who drink it. Thankfully, we are very early users of our water source. This means our source water hasn't had as much opportunity to be contaminated. Remember that all water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.
