From short hold times to the around the clock monitoring necessary, our highly-trained team is ready to provide accurate results using the most current methods in adherence to your project or permit-specific guidelines.

Enthalpy’s team of dedicated scientists and microbiologists analyze thousands of potable and non-potable water samples annually through our coliforms testing laboratory and legionella testing laboratory; we have one of the largest microbiology capacities in California.
