Additional analyses at a USGS lab in Menlo Park were also conducted, but not before the Technical Advisory Committee was given a tour of the USGS and an explanation of all that is entailed. In this photo, a USGS scientist explains data from the mobile laboratory to members of the Hinkley community.

Elisabeth LaBarbera, Andrea Jaegge, Nick Framsted, and Schuyler Nardelli hosted a workshop for the Expanding Your Horizons Conference. During lunchtime networking, Anna Conlen and Lawrence Fujiwara from the West Sacramento Projects Office hosted a USGS table where the girls were able to learn all about a future career with the USGS.

One part of the “Dive into the Bay Delta” workshop involved using Skittles to help demonstrate the concept of chromatography. Here, Elisabeth LaBarbera pours hot water over the Skittles and students observe how the running colors form a pattern. 

The USGS workshop called “Dive into the Bay-Delta” featured chromatography, microscopy, and sediment cores. Here USGS workshop leaders assist students with their hands-on activity.

A Pacific Gas and Electric Company (PG&E) compressor station in Hinkley, California. Although hexavalent chromium occurs naturally in groundwater in the Mojave Desert, concentrations increased in Hinkley Valley beginning in 1952 when the PG&E discharged it into unlined ponds. From there, hexavalent chromium entered the aquifer.

Hexavalent chromium, a known carcinogen under specific circumstances, occurs naturally in groundwater in the Mojave Desert. However, concentrations of hexavalent chromium increased in California’s Hinkley Valley beginning in 1952 when the Pacific Gas and Electric Company (PG&E) discharged it into unlined ponds.
