- Lead & copper - flagged from: LEAD AND COPPER RULE REVISIONS
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What ELDORADO's record does not cover
ELDORADO'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. This record - 1 health-based violation on file for ELDORADO - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
