Utilities staff: Aspens water meets standards; fluoride dosing and infrastructure questioned by council
Summary
Utilities staff briefed council on treatment steps, monitoring and disposal; they reported no recommendation to change community fluoridation and said Aspen meets state and federal guidelines. Councilors asked about naturally occurring fluoride, heavy metals and infrastructure lifespan and debated whether to send fluoridation to the ballot.
City utilities staff presented a detailed briefing on Aspens water-treatment process and monitoring at the Feb. 3 work session, describing sources (Maroon Creek and Castle Creek), treatment steps, solids handling and continuous monitoring. Justin Foreman, the utilities director, told council Aspens system supplies more than one billion gallons of potable water annually and that the department monitors parameters including pH, turbidity, chlorine and fluoride with state-required reporting.
"Aspen's water system delivers over 1,000,000,000 gallons of safe and reliable potable water per year for the community use and benefit," Foreman said. Staff explained that the city doses fluoride on-site and maintains a target fluoride recommendation set by health authorities (target 0.7 mg/L, acceptable range 0.6–0.9 mg/L) and that operators maintain a free-chlorine residual of at least 0.2 mg/L in the distribution system. Staff told council they have no recommendation at this time to change water treatment or community fluoridation and that they follow Colorado Department of Public Health and Environment (CDPHE) and EPA guidelines.
Council members raised several follow-ups. Councilor Bill proposed putting the fluoridation question to a November ballot advisory vote, saying, "we put this on the November ballot and let the community decide." Councilor Sam said he supports the current dosing, quoting an established target: "that 0.7 is the right amount." Other councilors asked staff to review a recent court case and state guidance before taking further action; staff said they would provide more detailed materials and that the CDPHE letter in the packet addresses the cited litigation.
