Almost every drinking water utility nationwide has a common concern. PFAS. Drinking water utilities whose raw water source is under the influence of PFAS are required to gain compliance with the Maximum Contaminant Limits by April 2031. With the sheer volume of drinking water facilities across the US, it’s not unreasonable to anticipate that the demand and supply chain requests for treatment systems regardless of form, media, and services will be taxed. Proactive approaches to remediation will be necessary. Corbin, KY is no exception to this dilemma. Initial testing indicates that the Laurel River, the raw water source for Corbin, is impacted by PFAS at the withdrawal location. However, a nearby utility, Barbourville Water, uses Laurel River Lake as its raw water source. Testing has not shown that Barbourville’s source is impacted as it appears to be isolated from the influence of Laurel River. Additionally, other utilities in the area source their drinking water from the same lake location. Corbin commissioned a Preliminary Engineering Report (PER) to develop alternatives for PFAS compliance including onsite treatment – preferably with granular activated carbon (GAC)- or, in a unique arrangement, a shared raw water intake on Laurel River lake with Barbourville. The shared raw water intake presented interesting possibilities and challenges for both utilities. This presentation will identify the research, costs, potential regulations and other parameters used to develop the PER alternatives presented to Corbin for compliance.
