What We Do

The Water Infrastructure Division (WID) conducts customer-driven research and support, providing scientific leadership on national-scale problems associated with water quality in the built infrastructure.  Specifically, our research program addresses treatment strategies for drinking water contaminants such as cyanotoxins, disinfection by-products, inorganic contaminants, pathogens such as Legionella, Mycobacterium avium, and chemicals of emerging concern such as PFAS. 

We also conduct extensive research on corrosion control strategies and analysis of drinking water pipe scales to reduce lead and copper exposure.  In addition, WID conducts research in the areas of stormwater management and water reuse to improve best practices.  Hydraulic and water quality modeling for drinking water and stormwater management is also an important aspect of WID’s research portfolio. 

Using the scientific and technical expertise generated through research, WID scientists provide technical support to public water systems as well as state and local governments.  WID specializes in providing technical information to small water systems who have unique capabilities and needs.
