Alamosa council reviews pilot to make arsenic‑removing chemical on site
Summary
Alamosa staff presented a proposal to pilot on‑site generation of ferric reagent (Aquam Metrology Systems/AMS) funded via an Isle Utilities arrangement; generators cost about $640,000, state (CDPHE) approval and a monitored trial would be required before the city assumes costs.
Alamosa City Council on Tuesday reviewed a staff proposal to pilot an on‑site system that would produce a ferric reagent used to remove arsenic from the city’s drinking water. Staff said the technology, developed by Aquam Metrology Systems (AMS) and supported financially by Isle Utilities, could reduce corrosive impacts inside the plant and cut metals discharged to the wastewater system.
Harry, the city manager leading the Public Works presentation, told council members the current 2008 treatment plant meets state standards but relies on bulk ferric chloride that can be corrosive, has variable purity and presents supply‑security risks. Roy Saines, who runs Alamosa’s water treatment facility, described an in‑house pilot and said AMS’s on‑site generators produce a cleaner ferric reagent via electrolysis of certified steel plates.
The proposal calls for five generator units with an initial vendor price estimate of about $640,000 for equipment and commissioning; additional engineering…
