MPSL-DFW Facilities & Capabilities

Field Sampling

We provide field sampling for pollution studies pertaining to chemistry, biology, toxicology and habitat assessment in fresh, esturine and marine environments throughout the entire state of California.

  • Multiple Electrofishing vessels and backpack shockers that allows for project specific collection of freshwater fish without harming non-target species
  • Research vessels ranging from 17 to 22 feet readily equipped with sediment and water collection devices
  • Autonomous water chemistry collectors and sensors (YSI)
  • Trace metal and trace organic clean sampling and sample handling techniques
  • Acoustic Doppler Profilers providing real time flow measurements. Electromagnetic flow velocity meters for stream discharge.
  • Sediment sampling grabs and coring devices
  • Fish-trawls, invertebrate and plankton nets, traps and pole spears
  • California State University and Department of Fish and Game certified research divers. AAUS certified.
  • Proficient with current Biological Assessment in streams and wetlands. Benthic invertebrate collection and algae using the SWAMP protocol.
  • CRAM (California Rapid Assessment Methods) certified for riverine protocols
  • Trash assessment
  • Differential GPS and GIS capabilities for accurate site location and data analysis

 

Laboratory

  • ICP-MS analysis of trace metals in waters (EPA 1638, modified), tissues and sediments (EPA 200.8)
  • DMA80 analysis of mercury in tissues and sediments (EPA 7473)
  • CVAFS analysis of mercury in water (EPA 1631e, modified) and methylmercury in waters, sediments and tissues (EPA 1630, modified)
  • Chlorophyll (EPA 445.0, modified)
  • Total Suspended Solids (EPA 160.2, modified)
  • Suspended Sediment Concentration (ASTM D3977, modified)

Other analyses may be available.  For a complete list of analyses and costs, or copies of our modifications to EPA methods, please contact Wesley Heim.
