AU Expected Aquatic Life Support, Primary Contact Recreation, Domestic Water Supply; Food Procurement; Ground Water Recharge; Industrial Water Supply Use; Irrigation Use; Livestock Watering Use for Main Stem Segments (Solomon River segments 1, 3, 5, 6, 8, 12) 2 Salt Cr. (Minneapolis) AU Expected Aquatic Life Support, Primary Contact Recreation, Food Procurement Use for Main Stem Segments (Salt Creek segments 27, 29, 30) Upper Solomon R. AU Expected Aquatic Life Support, Primary Contact Recreation, Domestic Water Supply; Food Procurement; Ground Water Recharge; Industrial Water Supply Use; Irrigation Use; Livestock Watering Use for Main Stem Segments (Solomon River segments 12, 14, 16, 23). Limestone Cr. AU Expected Aquatic Life Support, Primary Contact Recreation, Domestic Water Supply; Food Procurement; Ground Water Recharge; Industrial Water Supply Use; Irrigation Use; Livestock Watering Use for Main Stem Segments (Limestone Creek segments 18, 19). Impaired Use: Domestic Water Supply (Potentially) Water Quality Standard: Domestic Water Supply: 250 mg/L at any point of domestic water supply diversion (K.A.R.28-16-28e(c) (3) (A); Livestock Watering: 1,000 mg/L (Table 1a of K.A.R. 28-16-28e(d)); In stream segments where background concentrations of naturally occurring substances, including chlorides and sulfates, exceed the water quality criteria listed in Table 1a of KAR 28-16-28e(d), at ambient flow, the existing water quality shall be maintained, and the newly established numeric criteria shall be the background concentration, as defined in KAR 28-16-28b(e). Background concentrations shall be established using the methods outlined in the “Kansas implementation procedures: surface water quality standards,” dated August 6, 2001. (KAR 28-16-28e(b)(9)). 2. CURRENT WATER QUALITY CONDITION AND DESIRED ENDPOINT Level of Support for Designated Use under 2002 303(d): Not Supporting Domestic Water Supply Use. Monitoring Sites: Station 266 at Niles (Lower Solomon River); Station 512 near Minneapolis (Salt Creek); Station 511 near Glasco (Upper Solomon River); Station 667 near Glen Elder (Limestone Creek). Period of Record Used: 1990 – 2001 for Stations 266, 511 and 512; 1991 –1997, 1999 and 2001 for Station 667 (Figures 3, 4, 5, and 6, respectively).
