Data Mining SDWIS - Phosphate Usage Trends in Community Water Systems
Citation:
Pinelli, M., A. Porter, D. Lytle, AND P. Jordan. Data Mining SDWIS - Phosphate Usage Trends in Community Water Systems. 20th Annual Drinking Water Workshop, Covington, KY, September 12 - 14, 2023.
Impact/Purpose:
The Safe Drinking Water Information System (SDWIS/FED) contains data about nearly 50,000 community water systems (CWSs) and represents a wealth of largely untapped information regarding corrosion control practices. This poster illustrates trends in phosphate use by CWSs based on data contained within SWWIS/FED. Type of phosphate, CWS size, CWS location, source water type, and other factors are shown. This information will be useful to observers at the 20th Annual EPA Drinking Water Workshop, who can see general trends in phosphate use and compare them to specific water systems or groups of systems.
Description:
This poster explores trends in phosphate use by community water systems (CWSs) based on data contained within the Federal Safe Drinking Water Information System. Type of phosphate, CWS size, CWS location, and other factors were considered. It will be presented at the 20th Annual EPA Drinking Water Workshop.
