Development of a portable water quality sensor for river monitoring from small rafts

摘要

The 2015 Gold King Mine spill exposed the Animas River (located in Durango, Colorado) to over 3 million gallons of toxic water with spiked levels of arsenic and lead among other metals. In response to public concern for the quality of the river's water, a water quality monitoring system has been developed and deployed. Multiple organizations, both local and federal, have joined forces to understand the effects of the spill, and develop a method for continued sampling and remediation. However, most of the sensor network implemented consists of static sensors at conveniently located or easily accessible locations.
