The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.
Each card names which Rockport findings its current certification covers, and which it doesn't.

2 of 29 PFAS tested were detected in Rockport’s record (PFBA 13.2 ng/L and PFPeA 4.2 ng/L). If PFAS matters to you, a filter certification names each compound it covers.

Your path: My water tastes of chlorineThe disinfectant is not in this record
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
