Stormwater

ESB has been providing for the collection and testing of stormwater samples since the inception of the stormwater runoff program. Our laboratory and its partners provide complete analytical services for the NPDES programs administered by the State Water Quality Control Board for:

• Industrial Stormwater
  
• Construction Activities
  
• Municipalities
  
• Caltrans

Industrial Stormwater

On October 1st, the "wet season" officially begins, and those who have stormwater permits issued by one of the California Regional Water Quality Control Boards will have to sample at least two storm events before the end of May. As detailed in each General Permit Holder’s Storm Water Pollution Prevention Plan (SWPPP), the tests required for all facilities include:

• Total Suspended Solids
  
• pH
  
• Oil & Grease or Total Organic Carbon
  
• Specific Electrical Conductance

Additional tests are determined by the category of the industry (SIC) and the contaminants most likely to be found in runoff from the location.

We can provide sample kits and recommend orders are placed in advance of the October 1st starting date. To order a sampling kit, please send your list of analytes to: ciijima@babcocklabs.com or visit our bottle order page.

Construction

The Construction General Permit also requires the development and implementation of a Storm Water Pollution Prevention Plan (SWPPP). In certain watersheds and conditions, chemical monitoring for "non-visible" pollutants and sediments may be necessary. ESB offers laboratory testing to meet the requirements of the Construction Activities Permit.

Municipalities & Caltrans

Our laboratory also works with many cities, counties and the transportation department to meet the monitoring needs of their Stormwater programs. We provide compositing and maintenance of automated sampler equipment in conjunction with the analytical reporting required.
