Industrial Stormwater

Environmental laboratory testing services for Industrial General Permit (IGP) stormwater requirements

Under the new Industrial General Permit (IGP) issued by the California Regional Water Quality Control Board, the permit holder is required to collect and analyze storm water samples from each discharge location for two Qualified Stormwater Events (QSEs) within the first half of each reporting year (July 1 to December 31), and two QSEs within the second half of each reporting year (January 1st to June 30th). As detailed in each IGP holder’s Storm Water Pollution Prevention Plan (SWPPP), the tests required for all facilities include:

  • Total Suspended Solids (TSS)
  • pH (in the field)
  • Oil & Grease

Additional tests are determined by the category of the industry (SIC) and the contaminants most likely to be found in runoff from the location. All Dischargers are required to submit and certify all reports electronically via the Storm Water Multiple Application and Report Tracking System (SMARTS). 

We can provide stormwater sampling kits and recommend orders be placed in advance. To order a sampling kit, please send your list of analytes to our Director of Client Services, Cathy Iijima, or your Project Manager.


Construction

Environmental laboratory testing services to meet the requirements of the Construction Storm Water Program

Dischargers whose projects disturb one or more acres of soil or whose projects disturb less than one acre but are part of a larger common plan of development that in total disturbs one or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit Order 2009-0009-DWQ). Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility.

Babcock Labs offers laboratory testing to meet the requirements of the Construction Storm Water Program.  Please contact your Project Manager for more details.

Special Project Accommodation

Analytical testing laboratory that provides special project accommodation 

At Babcock Laboratories we understand that your samples and projects don’t fit neatly into the network laboratory mass-production line. Your samples are unique. Our chemists and microbiologists take professional pride in knowing the systems and companies we serve on a personal level and in helping clients to resolve their technical challenges. We accommodate special projects by offering greater analytical sensitivity, customized analytical testing, and much more!


Greater Analytical Sensitivity

Our laboratory offers greater analytical sensitivity

When clients experience regulatory requirements demanding greater analytical sensitivity, they trust Babcock Labs to meet their needs. Our chemists use their experience and understanding of methods and instrumentation to find appropriate techniques while ensuring proper method validation, reporting limit reproducibility, and quality control. We were the first lab in the country to utilize LC/MS/MS for the robust, reproducible measurement of Pyrethroid pesticides. Using a technique superior to traditional GC/MS we are able to analyze for all eight of the critical Pyrethrins to a reporting limit of one part per trillion (PPT), thus providing local agencies with defensible data to meet their stormwater monitoring permit requirements.
