Electrical conductivity range in soil
WebMar 6, 2012 · The conductivity of rivers in the United States generally ranges from 50 to 1500 µmhos/cm. Studies of inland fresh waters indicate that streams supporting good mixed fisheries have a range between 150 and 500 µhos/cm. Conductivity outside this range could indicate that the water is not suitable for certain species of fish or macroinvertebrates. http://traceandsave.com/what-can-electrical-conductivity-tell-us-about-our-soil/
