Nothing in this water calls for whole-house treatment. A drinking-water filter covers the exposure that matters. Whole-house units here are optional, mainly for taste and chlorine.
Detections ranked by share of the limitevery Tier 1 detection, highest first
Bar length is the highest result in the last 36 months as a share of the federal limit (MCL, or action level for lead and copper). The dark tick marks the limit. Gross alpha is compared after subtracting uranium, as DEQ does for compliance.

ppb = parts per billion (µg/L), ppm = parts per million (mg/L), ppt = parts per trillion. ND = not detected above the lab's reporting limit. MCL = federal maximum contaminant level; AL = action level for lead and copper (90th percentile of home taps); aesthetic = secondary standard for taste, odor or staining, not health. Bars show the highest result in 36 months as a share of the limit.
Hardness
Hardness is not reported in the latest CCR. Hardness not reported for this system; softener sizing uses a regional default of 11.7 gpg until a CCR value is reviewed.

Monitoring and reporting violations (2)
A required sample or report was late or missing. These do not mean a contaminant was found, but a system that skips monitoring has gaps in its record.

Lead and copper at the tap90th percentile of sampled homes against the action level
90th percentile of samples taken at customer taps. Results depend on the home's plumbing. Results are from sampled homes in this system, not from your tap. Home plumbing can add lead and copper. First-draw samples run higher than flushed ones.
