Colorado River Testing
|
During our journey along the Colorado River, from the headwaters
deep in Rocky Mountain National Park to Yuma, Arizona where the mighty
river leaves the United States, we have been testing four different
aspects of the water: Salinity, Total Dissolved Solids (TDS),
Conductivity, and Temperature. LaMOTTE Company donated a TRACER
Pocket Tester (#1749) for our use. It allows for the above tests
to be done using one 20ml sample of water. Temperature was
collected using a LaMotte Water Thermometer (#1066).
