LADS interpretation
What the evidence means—and does not mean
- The 167 mg/L hardness value belongs to the City reporting context, not every Richmond postal address.
- Main System and Riverpark West results differ and must remain attached to their PWS IDs.
- Verify current hardness at the untreated tap before equipment sizing.
Measured fact
Values above stay tied to their named system, units, sample or report year, and official source.
