The EIDO is a low cost, real-time sensing platform, specifically designed for monitoring organic water quality parameters including BOD, COD, TOC and Coliforms (total, E. coli or fecal). Following the success of the award-winning Proteus, the EIDO has been specifically designed as a low-cost option for the measurement of organic parameters. The EIDO has been designed for its ease of use, reliable data and economical operation even in the toughest applications. Available in two sizes, the EIDO 30 provides turbidity, TSS, temperature and two fluorometers; while the EIDO 35 provides turbidity, TSS, temperature and up to four fluorometers.

Supplying Seattle’s Drinking Water: Using Data Buoys to Monitor the Cedar River Municipal Watershed
Providing clean, safe, and reliable drinking water for the 1.6 million people in the greater Seattle area is a top priority for Seattle Public Utilities (SPU). With limited water supplies, SPU dedicates considerable resources to maintain its watersheds and mountain reservoirs. About 70 percent of Seattle Water comes from the Cedar River Municipal Watershed , and the other 30 percent comes from the South Fork Tolt River Watershed .

Data-Driven Advocacy on the Lower Deschutes River
Like many freshwater environments, the Deschutes River in Oregon is under pressure from development, pollution, and climate change. Many rivers, streams and lakes in the Deschutes Basin do not meet Oregon water quality standards –where state water quality monitoring assesses levels of bacteria, pH, dissolved oxygen, temperature, and fine sediment. Hannah Camel is the Water Quality Coordinator for the Deschutes River Alliance (DRA), a non-profit organization that focuses on the health of the lower 100 miles of the Deschutes River–the area most affected by human intervention. As a data-driven organization, the DRA has benefited from the installation of two NexSens X2 data loggers.

Expanding the Port Everglades: Real-Time Monitoring of Water Quality Conditions from Planned Dredging Operation
The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions. [caption id="attachment_39497" align="aligncenter" width="2560"] A CB-950 and CB-25 deployed on site at Port Everglades.
