Overview
Hach Nitrate/Nitrite Model NI-12 Color Disc Test Kit features a continuous-gradient color wheel for fast, accurate comparisons. The continuous color provides higher levels of accuracy. The Hach nitrate/nitrite color disc test kit also uses a blank as a reference in color comparison, compensating for color in the sample.
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.

Kansas State classes get a lesson in environmental remediation
Kansas State University professors transformed a plot of land from a problem to a classroom, teaching students on the fly to remediate nutrient pollution. 
 Saugata Datta, an associate professor of geology, and Nathan Nelson, an associate professor of agronomy, taught students to evaluate, sample and remediate land using Kansas Department of Health and Environment protocols. 
 It started when Chris Steincamp, an environmental lawyer and KSU alumnus, asked Datta if his geology students could restore a tract of land in Sylvan Grove Kan. 
 Datta jumped at the opportunity to give his students hands-on experience in a process usually reserved for regulators and consultants. 
 It helped that O.C.

Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. 
 
 Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing.

Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.
