Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety
9/28/2005
A water utility in Ohio wanted to learn more about the variability of water quality parameters such as pH, ORP, turbidity, and chlorine. Previously, most of these parameters had been measured by spot sampling protocols with only a few measurements during a daily period. In order to more accurately assess the water variability, the utility used a YSI 6920DW Drinking Water Multiprobe

Phosphate In Groundwater And Surface Water: A Rapid And Reliable Determination Method Using The Photometric Spectroquant® Test
1/31/2019
Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO4-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.
