City of Wellman, Texas - Arsenic Treatment System


Courtesy of Adedge Water Technologies, LLC

The City of Wellman, Texas (Wellman) applied to the U.S. Environmental Protection Agency (USEPA) to participate in the arsenic treatment demonstration program for Round 2 and was selected. Wellman has five water-supply wells which pump water to a 110,000 gallon storage tank. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). AdEdge Technologies Inc. (AdEdge) contacted the city and presented a proposal for arsenic treatment using granular ferric oxide (GFO) technology. AdEdge was subsequently selected and awarded the project (i.e., one of nine USEPA demonstration sites awarded to AdEdge). AdEdge worked with Oller Engineering Inc. (OEI), the water system’s engineer, in preparing permitting submittals and working toward Texas Commission on Environmental Quality (TCEQ) regulatory approvals for construction and installation of the system and associated appurtenances. AdEdge and OEI submitted an exception request for the arsenic treatment system, which has been approved.
