Excelling in Analysis of Water at Low Levels
Napa, California based Caltest Analytical Laboratory is a specialized commercial environmental analytical chemistry lab focusing on analyses of regulated pollutants at low levels in water. Caltest has been an early adopter of technology improvements in commercial lab analyses. This has resulted in performing with high reliability at lower concentrations.
Caltest is a market leader in low-level analyses of wastewater, groundwater, and tests water for regulatory permit compliance. Caltest also provides analyses of non-radioactive water, and hazardous waste samples. We are proficient in complex analyses of volatile and semi-volatile organics, pesticides, explosives, trace metals, nutrients, anions, solids, microbiology, and wastewater loading parameters.
We are proud of our high client retention rate, and the excellent reputation we have earned among our clients, especially clients who work in labs themselves, or have worked in labs (POTW, National Labs, water plants, refinery labs and engineering firm project chemists).
Accreditation
Caltest is accredited by the State of California Environmental Laboratory Accreditation Program (ELAP 1664) and in the United States by the National Environmental Laboratory Accreditation Program (NELAP) through the State of Oregon (ORELAP 4036).

Mission Statement
Caltest Analytical Laboratory exists for the purpose of providing:
- Well respected analytical services
- A good work environment for its employees
- A reasonable return to its investors
As a value driven company, we seek to provide high-quality data, a good work environment for our employees and a reasonable return to our investors. We are committed towards establishing great customer relations by being honest, responsive, and courteous in all our dealings. We continually seek better ways to produce analytical data more efficiently and reliably and at lower levels of detection.
Caltest is a stable company under the same ownership for more than 40 years. The lab is operated conservatively, profitably, and has never been in any bankruptcy, contract disputes, or regulatory investigations.
We believe that it is very unlikely that a lab can produce consistent quality if the staff is unstable or professionally unsatisfied. We strive to make Caltest a great place to work, and to work with.
