Table A16. Kansas Geological Survey analyses of water samples collected from the Arkansas River near or at Dodge City, Ford County, Kansas. The first two samples were collected at the multi-level observation well site west of Dodge City (26S-25W-29CCCA). Most of the samples were collected at the 14th Avenue bridge where there is a USGS gaging station (26S-25W-35BCC). The last three samples were collected between Dodge City and Fort Dodge (27S-24W-05BBD).

Table A18. Kansas Geological Survey analyses of water samples collected from the Arkansas River near Kinsley, Edwards County, Kansas. The first two samples were collected below the Highway 183 bridge south of Kinsley (25S-19W-9ADD); the last two samples were collected below the Highway 50 bridge east of Kinsley (24S-19W-26DCD).
