WSB PROJECT EXPERIENCE EXAMPLE <br /> Granular Activated Carbon Water Treatment Plant <br /> CLIENT: CITY OF ST. PAUL PARK <br /> LOCATION: ST. PAUL PARK, MN <br /> DURATION: 2020 <br /> The Granular Activated Carbon Water Treatment Plant <br /> was constructed to support public health by bringing <br /> cleaner drinking water to residents and businesses <br /> within the St. Paul Park community.Since 2007,the <br /> Minnesota Department of Health (MDH) has been <br /> h'y <br /> monitoring the concentration levels of perfluoroalkyl <br /> and polyfluoroalkyl substances(PFAS)in the city's water <br /> supply. PFAS are a family of manmade chemicals that <br /> do not naturally decompose due to their heat and water ` <br /> resistant structure. Studies have found that consuming <br /> drinking water with elevated levels of PFAS,over time, j <br /> can be associated with high cholesterol, reduced <br /> immune response,thyroid disease, kidney cancer and <br /> other distressing health problems. <br /> In June of 2018,the MDH notified St. Paul Park officials, <br /> stating that two of its three water wells exceeded <br /> the recommended amount of PFAS to be considered <br /> safe for public consumption. In response to this <br /> pervasive health threat,WSB partnered with the city + ` <br /> to design a water treatment facility and remove PFAS ` <br /> from the community drinking water and surrounding ' -yY <br /> environment.After completing a feasibility study, <br /> Granular Activated Carbon (GAC)Water Treatment Plant ` <br /> was designed, bid and constructed.The GAC Water k ` <br /> Treatment Plant was delivered under budget and on <br /> schedule. <br /> KEY WSB STAFF GREG JOHNSON, JON CHRISTENSEN, <br /> GREG GLUNZ <br /> A Proposal for Design,Bidding,and Construction Administration for a <br /> Water Treatment Plant for City of Lino Lakes Relative Experience,Qualifications,&References 28 <br />
