Reference number : GC-2017-Q4-00621, amendment number : , agreement type : G, recipient legal name : Gagnon, Graham (Dalhousie University), recipient country : CA, recipient province : nan, recipient city : Nova Scotia|Nouvelle-Écosse, recipient postal code : nan, program name english : Collaborative Research and Development Grants - Project, program name french : Subventions de recherche et développement coopérative - projet, program purpose english : Health Canada has recently proposed changes to the guideline for lead in drinking water. These changes would reduce the maximum acceptable concentration of lead in drinking water to 5 µg/L and specify sampling protocols for determining lead levels in residential and non-residential buildings._x000D_

While the water industry, in general, has observed positive outcomes with phosphate as a chemical product for corrosion control, challenges remain. Specific challenges include concern for the role phosphates may play in biofilm formation and the long-term availability of phosphates in the marketplace. Silicates are an alternative that have been used in the drinking water industry for iron and manganese control for decades; however, their reported application for corrosion control in drinking water has been relatively limited in the peer review literature. _x000D_

National Silicates has identified an opportunity to capitalize on the need in the water industry to better understand corrosion control products to address concerns with lead and other metals. There are presently relatively few published studies concerning silicates, both in application and at a fundamental level. Accordingly, this project aims to close that gap._x000D_

The overall goal of this 24-month project is to enhance the water community's understanding of sodium silicates for controlling lead and biofilms in drinking water distribution systems. The research project will utilize a new product formulation provided by National Silicates designed for the drinking water industry. The research project will be conducted at the laboratory-scale level and the pilot-scale level to obtain an understanding of sodium silicates at both a fundamental and applied level.  _x000D_
