Have you ever found yourself needing to remain in compliance with your local groundwater agency?  We have the partner to help with that!  Introducing Zalco Laboratories Inc., of Bakersfield, California. Zalco Laboratories Inc. would be honored to assist you with any agricultural laboratory testing you may need.

Zalco Lab was founded in Bakersfield in 1979 by Dr. John Zaletel and Jim Etherton.  The lab started as a small, independent testing lab for the petroleum industry in Central California but quickly grew into a full-service, state-of-the-art testing facility. Today, Zalco Laboratories Inc., is certified through the State of California Environmental Laboratory Accreditation Program (ELAP) for the analysis of drinking water, ground water, surface water, wastewater, and hazardous waste. Zalco Laboratories Inc. also provides analysis of crude oil and natural gas for the Oil and Gas industry.

To get started with Zalco Laboratories Inc., give them a call at (661)395-0539 or send them an email at A staff member will direct you to collect a water sample in a specified and sterile sample container and deliver it to the laboratory. The three ways to deliver samples to the laboratory are: through a field technician collecting samples for you, personally delivering samples to the lab, or shipping your samples in the mail. Testing is performed as required by the regulating agency, for example, local, state, or county Water Boards.

Sampling costs vary due to each county’s own testing requirements for new private water wells. According to a spokesman at Zalco Laboratory, “for example, Kern County testing requirements for new domestic wells costs $460 and $330 for an irrigation well. Different testing rules apply for Irrigation districts/water districts who supply domestic water for the community. In general, the testing involved covers General Mineral, General Physical, Inorganic Chemical, Bacteriological, and Organic Chemicals.”

So why use Zalco Laboratories, Inc.? First of all, they’re friends of Water Wrights and just plain down to earth people. More importantly, they are ELAP certified, which meets most local water agency testing requirements for groundwater analysis. What’s ELAP you ask? It is the Environmental Laboratory Accreditation Program (ELAP) certification that is obtained through biannual audits from ELAP Auditors, which visit a laboratory for two days inspecting analytical data to ensure that its methods are followed to a T. Zalco Lab also participates in an annual Performance Evaluation of samples that are also required as part of the re-certification process. Most importantly, the staff at Zalco Labs is highly qualified and trained in field sampling which can be performed throughout the state of California.
