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

Sawtooth Estates Water Users reports hardness of 8.8 grains per gallon (151 mg/L as CaCO3), classified as hard in DEQ compliance sampling. At 7 grains per gallon or more, a correctly sized softener usually pays for itself in appliance life and soap. Hardness is not a federal health violation.

Monitoring and reporting violations (3)

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.

Questions about Sawtooth Estates Water Users

Is Sawtooth Estates Water Users tap water safe to drink?

In the last 36 months at least one result for Sawtooth Estates Water Users was above a federal limit: Lead. A single high sample is not always a violation because compliance is often judged on a running average; the violations section shows what EPA recorded. Results reflect the system's sampling points, not the plumbing in any one home.

Is Sawtooth Estates Water Users water hard?

Sawtooth Estates Water Users reports hardness of 8.8 grains per gallon (151 mg/L as CaCO3), classified as hard. Hardness is not a health issue. At 7 grains or more most households see scale and soap scum; a softener is a reasonable choice.

Is Sawtooth Estates Water Users water fluoridated?

Fluoride was measured at up to 0.32 mg/L, below the 0.7 mg/L level used for community fluoridation, so it is naturally occurring rather than added. The federal limit (MCL) is 4 mg/L.

Where does Sawtooth Estates Water Users water come from?

Sawtooth Estates Water Users draws from 2 active wells with 2 treatment plants on record. Source and treatment details are listed above.

What filter fits Sawtooth Estates Water Users water?

For drinking water the matching engine ranks Aquasana OptimH2O Reverse Osmosis + Claryum first for this profile, based on certified reduction claims for the contaminants flagged above. See the filters section for the reasoning and alternatives.
