You will need to supply your billing and reporting address at that time.
Our standard terms are net 30 days from the invoice date. A Credit Application is needed for any work that is not paid for in advance. We also accept Visa and Mastercard.
What are your procedures for new projects?
To insure that your project will go as smoothly as possible, please refer to our New Project Checklist to get started.
Does your laboratory offer Electronic Data Deliverables?
Yes, ESB supports our clients with many Electronic Data Deliverable formats including the State of California's Write-On Program, Excel, Access, etc. Or, you can have your hard copies put into a PDF format and emailed to you. Please contact your Project Manager for more information.
How much advance notice is needed for bottle order kits?
A minimum of 24 hours advance notice is needed to put together bottle
orders and have them shipped to your location. A standard charge of
$20.00 per shipment will be assessed. Most bottle orders are shipped
via UPS Ground. Should overnight service be required, additional charges
What types of bottles do I need?
The bottles that you need depend upon the type of analyses requested. For a complete listing of sample containers, preservation techniques, and holding times click here. To view the types of bottles we commonly use, click here.
For a complete California Title 22 Analysis, the following bottles would be required (click here). If you have any questions, please contact your Project Manager.
What is your standard turnaround time?
Turnaround for analytical results will vary depending upon the analyte(s), matrix type, and the regulatory requirements for the samples submitted. In general, Babcock provides test results within 10 working days.
What rush turnaround times are available?
Rush turnaround of samples depends upon the degree of sample prep and extraction that is required by the applicable methods. In general, Babcock offers rush turnaround in 24, 48 and 72 hours as well as 1 week. All rush turnaround capability is dependent upon the current laboratory workload and requires prior laboratory approval.
Which commonly performed analyses have short holding times?
pH, chlorine residual: 15 minutes - best if performed on-site, Dissolved oxygen: 8 hours - if fixed on site, Hexavalent Chromium: 24 hours, BOD, Nitrate, Nitrite, Turbidity, MBAS, Orthophosphate, Settleable Solids: 48 hours, Microbiological analyses: (Drinking Water): 30 hours, (Wastewater): 8 hours, (Source water): 8 hours.
How can I locate more information about a particular analyte (Synonyms, Method Numbers, etc)?
We have found the web site www.chemfinder.com to be very useful for this task.
Why are reporting limits sometimes elevated in a result?
The reporting limits that can be achieved on actual environmental samples can be influenced by a number of factors such as sample size, final extraction volume, injection volume, dilutions, instrument sensitivity, and matrix interferences. For example, if dilution of the sample is necessary due to matrix interference, the reporting limit must be adjusted to account for the dilution factor used. A ten-fold dilution will result in the reporting limit being elevated by a corresponding factor of ten.
