Overview
The Hach Model CO-1 Color Disc Kits feature a continuous-gradient color wheel for fast, accurate comparisons. The continuous color provides higher levels of accuracy. Kits also use a blank as a reference in color comparison, compensating for color in the sample. The Hach Color Disc test kit provides limitless visual tests and measures color in units ranging from 0-100 and 0-500.
Mechanics
Simply react the sample, then insert the blank and the sample into the holder. Rotate the color wheel to obtain a color match between the blank and the reacted sample. Accuracy for color disc kits is typically +/- 10% or +/- the smallest increment, subject to individual color perception.

Monitoring Lake Erie’s Eastern Basin: Building Long-Term Data and Real-Time Public Solutions
In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.

Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.

Wesley Turner, an Environmental Scientist Advisor with the GIS and Data Analysis Section of the Watershed Management Branch in the Kentucky Division of Water , spends his days researching current technology and developing various drone programs for the Division of Water. 
 
Having grown up during Love Canal and Valley of the Drums, Turner decided at a young age that he wanted to become a scientist and spend his life trying to right humanity’s wrongs and protect the environment. 
 
“I loved looking at the plants and animals on the farm where I lived. I wondered at the beauty and mystery of the soil and water in the surrounding fields. As I grew older, I learned of the problems our species caused on the planet […] I remember thinking things had to change,” recalls Turner.
