The City of Hamilton’s Water Division developed a Surface Water Quality Program (SWQP) that samples surface water locations monthly, throughout the City’s waterways. The purpose of this program is to work with and alongside internal and external Stakeholders to develop and monitor baseline surface water quality conditions.
Data on the Surface Water Sample Locations is provided through the Open Hamilton Data Portal which is a public-facing resource for up-to-date, easy and transparent data for surface water quality general knowledge, trending, review and research purposes.
Surface Water Sample Locations
The data associated with this program is uploaded to the website on a quarterly basis. The website was last updated March 2022, providing all relevant 2021, and January and February 2022 surface water quality data, through Open Hamilton.
