This is an example of how to create a water report post.
If you know your city's water source, you might want to include that information here in the body. For Carrollton, our water souce is the Elm Fork of the Trinity River which comes from Lake Lewisville.
You may also want to include information about the lab which performed the testing. Such as the lab name and web site could be useful.
The sample report I posted here is from the City of Carrollton. It's not focused on water salts important to brewing, but does have some useful information
