A Local Issue Worth Knowing About
PFAS in Our Water Supply —
What Camas Residents Should Know
PFAS — per- and polyfluoroalkyl substances — are a group of synthetic chemicals that have been used in manufacturing and consumer products for decades. They're called "forever chemicals" because they don't break down naturally in the environment or in the human body.
Elevated PFAS levels have been detected in certain wells in the Camas area. While municipal water treatment addresses many contaminants, private well owners in particular face real exposure risk — and even treated municipal water can carry trace levels that some families prefer to filter out entirely.
Reverse osmosis is one of the most effective filtration methods available for PFAS removal — eliminating up to 95% or more of PFAS compounds, along with a wide range of other contaminants. It's the solution we most frequently recommend when water quality is a concern.

Beyond PFAS
A properly installed RO system addresses a wide range of water quality concerns — not just PFAS.
- PFAS / PFOA / PFOS forever chemicals
- Lead and heavy metals
- Chlorine and chloramines
- Nitrates and nitrites
- Arsenic
- Bacteria and cysts
- Sediment and turbidity
- Pharmaceuticals and microplastics
Your Options
Point-of-Use or Whole House —
Which System Is Right for You?
Point-of-Use System
Installed under the kitchen sink, a point-of-use RO system filters water at a dedicated faucet. This is the most common entry point — highly effective, minimal footprint, and typically the most affordable option. Ideal for families who want clean drinking and cooking water without filtrating every drop that enters the home.
- Dedicated filtered water tap at the sink
- Typically 3–5 stage filtration
- Compact under-sink installation
- Storage tank for on-demand supply
- Filter replacement every 6–12 months
- Great for renters or as a starting point
Whole House System
A whole-house system treats water at the point of entry, so every faucet, shower, washing machine, and appliance in your home receives filtered water. This is the right choice for well owners with serious contamination concerns, or households where PFAS exposure through skin contact and inhalation during showering is a priority.
- Filtration at the main water line
- Covers all fixtures and appliances
- Protects water heater and pipes
- Addresses inhalation & skin exposure
- Ideal for private well systems
- Higher upfront cost, broader protection
