In Oregons Willamette Valley, where agricultural fields bump up against the banks of the Willamette River, levels of chemical fertilizers and animal waste in the water are often higher than the recommended standards, with US, nitrates, E. coli, and algae in the water being particularly worrisome. Corvallis Oregon is now using a new device called The LiquID™ Station which is an optical monitoring instrument that allows for continuous observation of water quality and then makes the information available online. It works by pumping water into the machine, then passing it through a single, innovative optical flow cell utilizing fluorescence, UV-Vis absorption, and “hybrid-hyperspectral” detection. The instrument takes readings about every two minutes eliminating the need to use wastewater sampling equipment .

The instrument takes readings about every two minutes and produces no waste other than that which may have already been in the water sample.
