You don’t just drink your water. You live in it.
Independent lab analysis of 100+ contaminants — including arsenic, lead, uranium, nitrates, disinfection byproducts, and heavy metals — interpreted against California Public Health Goals.
Measured against health-based standards — not just legal limits.
Water chemistry shifts over time. Infrastructure ages. Source water blends change. We establish a laboratory baseline for your home and interpret it against Public Health Goals.
The Mireau Method
No averages or strips. Samples are:
- Collected with chain-of-custody
- Lab-analyzed by third-party
- Measured via EPA methods
- Reported with limits
No assumptions. No averages. Only measured data.

Each bar shows how far your detected level exceeds California's Public Health Goal — the concentration scientists say is safe for lifetime exposure. The red line is 1x: the safe threshold.
In this home, several contaminants were detected at levels significantly above California’s Public Health Goals for lifetime health protection.
California PHG Safe Level
Why health-based benchmarks matter.
Low-level exposure is cumulative.
Lead
Neurotoxic metal assessed against California health-based benchmarks, with particular relevance for long-term exposure and sensitive populations.
Arsenic
Naturally occurring in certain groundwater sources. Measured concentrations are compared to California Public Health Goals to assess cumulative risk.
Nitrate
Common in areas influenced by agricultural runoff. Evaluated for long-term ingestion safety using health-based targets.
Disinfection Byproducts (THMs)
Formed during municipal chlorination. Assessed against California Public Health Goals for lifetime exposure considerations.
What This Means for Your Home
Regulatory limits define legal compliance. Health-based goals help determine whether further action may be appropriate. Every Mireau analysis translates laboratory data into clear context — so decisions are based on measured exposure, not assumptions.
