They are open and share <br />information at all levels and enable our staff to be as self-sufficient as possible. We value our <br />relationship with AE2S and the benefit they bring to our staff and community." <br />JIM WESTERMAN, Utilities Division Manager <br />jim.westerman©woodburymn.gov <br />651-714-3720 <br />Woodbury, Vinnesota <br />WATER TREATMENT AND MANAGEMENT <br />Ground Water Contamination <br />Concerns Lead to Treatment <br />In 2004, PFAS were first found <br />to have contaminated drinking water <br />supplies in parts of the eastern Twin <br />Cities. Over the last 15 years or so, PFAS <br />have been discovered in Woodbury's <br />groundwater supply and research has <br />been conducted to identify the source <br />and level of contamination. Most of <br />the contamination has been traced to <br />four dumps or landfills in Oakdale and <br />Woodbury, at the 3M manufacturing <br />facility. <br />In November 2017, the MDH <br />notified the City ofWoodbury that of <br />Woodbury's 19 municipal wells, water <br />from five wells - based on the most current <br />data - exceed either a PFAS health -based <br />guidance value (HBV) and/or a health <br />risk index (HRI) value. <br />On February 20, 2018, the State of <br />Minnesota settled its lawsuit against the <br />3M Company in return for a settlement of <br />$850 million. <br />APWA PROJECT OF THE YEAR <br />lNN-DV1QT <br />Un+h•,1 RanYnls <br />00-{f R-RENTS <br />Lawsuit Leads to Action <br />In response to this settlement, the <br />City ofWoodbury retained AE2S to <br />assist with the development of a PFAS <br />Treatment Master Plan. <br />The PFAS Treatment Master Plan <br />consisted of the alternative evaluation <br />and planning for a 30MGD WTP to treat <br />PFAS and potentially other treatment <br />target goals, such as iron and manganese <br />removal, radon removal, softening, <br />fluoridation, and disinfection. The study <br />also included a review of population and <br />water demand projections, evaluation <br />of current and future drinking water <br />regulations, completion of a source <br />water evaluation, a treatment technology <br />evaluation, and development of preferred <br />project alternatives for evaluation. <br />Various treatment technologies were <br />investigated, such as GAC, Ion Exchange, <br />Lime Softening, and RO/NF Membranes. <br />Focused Project Team Delivers a <br />Solution in Record Time <br />Following negotiations with the <br />State and the identification of a temporary <br />WTP site, Woodbury was awarded a <br />grant of $8,725,000 to design and build a <br />temporary WTP capable of treating 3,800 <br />gpm. AE2S jumped into action in early <br />2020 to begin planning for the design <br />and construction of a temporary WTP <br />with a goal of treatment being operational <br />by June 1, 2020. In addition to AE2S <br />beginning an expedited design process, <br />Woodbury determined that this was an <br />emergency and declared a City emergency <br />which allowed them to utilize a unique <br />CMAR (Construction Manager at Risk) <br />contracting method not yet allowed in <br />Minnesota. Through a seamless project <br />team between the City, AE2S, and the <br />contractor (Rice Lake Construction), <br />AE2S was able to deliver a successful <br />WTP on time and before summer peak <br />demand. <br />WHY THIS PROJECT? <br />• PFAS Removal <br />• City's First Water Treatment Plant <br />• Operator Training/Support <br />• Accelerated Schedule <br />Innovative Construction <br />Techniques <br />AE2S CITY OF RAMSEY DESIGN & CONSTRUCTION - MUNICIPAL WATER SUPPLY TREATMENT PROPOSAL 2.3 <br />
