I don't know, I have never checked salt content. There are saline marshes in the area though, the Lincoln area is also know as the "Salt Valley" and the road just north of our house of us is named "Little Salt" Road. The Salt Creek Tiger Beetle makes it home 4-5 miles straight south of our place.
My water has been very green most of the summer due to farm fertilizer run off in the water shed, secchi disk readings are currently running 12".
