4 <br />4.1 <br />• Synthetic Organic Compounds (SOCs) <br />• Metals <br />• Hormones <br />• Flame Retardants <br />• Per -fluorinated Compounds (PFAS) <br />• Disinfection Byproducts <br />• Cyanotoxin Chemicals <br />• Other chemicals used in industria and manufacturing practices <br />The majority of these contaminants are from anthropogenic, or human activity, sources, and thus <br />necessitates the need to be vigilant in protecting City's wells from pollution. As discussed further <br />in Chapter 5, the City's wells are well protected from anthropogenic pollution, but continued <br />safeguarding of the wells will be crucial in preventing a new contaminant in the City's drinking <br />water supply that requires treatment. <br />Although it isn't possible to predict what contaminants will be regulated in the future, having <br />flexibility in a treatment system is important to provide treatment options for possible future <br />contaminations, new regulations for contaminants, and as testing abilities continue to improve. <br />Water Demand <br />Ramsey's average daily water demand from 2009 to 2019 ranged from 1.6. to 1.9 million gallons <br />(MGD). The maximum daily demand, usually occurring during summer months due to lawn <br />watering and other non -consumptive use, ranged from 4.1 to 5_51V1GD_ <br />The projected annual average water demand for the City is expected to increase to 3,5 MGD and <br />up to a projected daily maximum of 10.3 MGD in the year 2040. A list of future water projections <br />from the Cityis Water Supply Plan is included below. <br />Table 8 - Projected Water Demands <br />II Projecte Projected <br />Yea Total oputation <br />opulati Served <br />2020 <br />2025 <br />27.550 <br />30,450 <br />13,921 <br />18,547 <br />Projected <br />Average Daily <br />Demand (MGD) <br />1.8 <br />2.4 <br />Projected Maximum <br />Daily 1:1 (MGD) <br />5.3 <br />7.0 <br />2030 <br />33,350 <br />22,987 <br />3.0 <br />8,7 <br />2040 <br />39,150 <br />26,988 <br />3_5 <br />10.3 <br />Adequacy of Existing Water Supply <br />As discussed in Section 1.2, if a central water treatment plant is constructed, Wells No. 1 and 2 <br />will not likely be connected to the water treatment plant. The existing firm capacity without <br />considering Wells No. 1 and 2 is 4,850 gpm or 7.0 MGD_ Table 8 predicts that Ramsey has <br />sufficient firm capacity without Wells No. 1 and 2 through the year 2025_ When maximum day <br />demands reach 7.0 MGD, Ramsey should consider drilling another well. <br />FEASIBILITY STUDY -DRAFT <br />Page 12 <br />RAMSY 154354 <br />
