Interpretations of the test results, interim reports of laboratory work, and research &development of special equipment or test procedures will be charged at our regular schedule ofprofessional services fees which is available upon request. Data on diskettes and/or electroniccopies (pdf files) may be available upon request. These will be charged at the samplepreparation hourly rate.

Turnaround times for testing vary upon the testing requested, preparation requirements,sample textures and volume of other testing being run at the time. For example, a hydraulicsproperties package suite of tests requires 6 to 10 weeks to complete.

DBS&A will dispose of all samples 30 days after completion of testing unless priorarrangements have been made.

Radioactive samples will be handled on a case-by-case basis. Clients are required todocument the chemical characteristics of samples containing any potentially hazardous orradioactive substances.

If you do not see the testing you would like, please call. Our testing services are updatedregularly. Please call 505-889-7752 to obtain pricing.
