Is SILVIS's water safe to drink?

The concern categories on record
SILVIS's flagged contaminants and rule violations, grouped by what they actually mean for a filter choice rather than left as EPA's raw code list:
- Lead & copper - flagged from: LEAD AND COPPER RULE REVISIONS
- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
- Radionuclides - flagged from: Combined Radium (-226 and -228); Gross Alpha, Excl. Radon and U
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What SILVIS's record does not cover
SILVIS's numbers here come from its own required reporting to EPA under the Safe Drinking Water Act, not from an independent test of your glass of water. Between the utility's meter and SILVIS's customers' taps is household plumbing, invisible to a system-level record ranked 3,411th of 12,903 by violation count. The guide to what this data misses covers that gap.
