What Makes Camas's Water Unique?

Local geology and source profile

Source: GroundwaterTDS: 144.6 mg/LpH: 7.6

The City of Camas operates the municipal utility serving Camas and nearby areas in Clark County. The system uses mixed sources: surface water from Boulder Creek and Jones Creek, supplemented by groundwater. Utility facilities treat both source types before distribution, and customer guidance and annual quality documentation are provided through the City of Camas Public Works Department. This combined-source design supports supply reliability while published annual Consumer Confidence Reports summarize treatment performance and tested parameters for residents throughout the service area.

Source waters originate in the Cascade foothills, where watershed terrain is dominated by Tertiary volcanic rocks and Quaternary glacial deposits. As water moves through volcanic soils and formations, especially basaltic and andesitic units common to the regional arc, mineral content and chemistry are shaped by rock-water contact. The draft characterizes this setting as producing a moderately mineralized profile typical of Pacific Northwest volcanic landscapes. With both creek and groundwater inputs, overall chemistry reflects a blend of these volcanically influenced source pathways and treatment outcomes.

For household use, the city directs residents to current annual reports for specific hardness values and full contaminant detail, and recommends practical steps such as standard water conservation and flushing when water has stagnated in plumbing. Third-party summaries cited at least one contaminant above EPA health-based guidelines while also noting the supply meets federal legal limits. On that basis, the provided guidance recommends certified water filters for added protection, especially for children, pregnant women, and immunocompromised individuals, with final treatment and safety details documented in annual CCRs.

Frequently Asked Questions

Is Camas's water safe to drink?
Yes. Camas's water meets all federal safety standards. The hardness is 61.5 mg/L (Moderately Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.
Do I need a water softener in Camas?
Camas's water is moderately hard at 61.5 mg/L. A water softener is generally not necessary, though a carbon filter can improve taste and remove any remaining chlorine.
How does Camas compare to the USA average?
The USA national average is 151 mg/L. Camas (61.5 mg/L) is 89 mg/L below the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Camas is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

Water Hardness

Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city β€” the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.

Estimated

pH

Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock β€” values may differ from utility-reported figures.

Estimated

TDS β€” Total Dissolved Solids

Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.

Measured

PFAS β€” Perfluoroalkyl and Polyfluoroalkyl Substances

EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) β€” sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.

Modelled

Lead

Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age β€” all estimates are maintained below the EPA action level of 0.015 mg/L.

Calculated

Appliance Lifespan

Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
