In April of 2010, Paul Hsieh, a research scientist, readily stepped up to an opportunity to provide a service to the public that pulled him away from his work, that pulled him out of his environment. This was not something that's in his job description, but it was a way for him to make a tangible contribution, and as it turned out, he made a significant difference.

Aqueous geochemistry of waters and hydrogeology of alluvial deposits, Pinnacles National Park, California
A borehole test for chlorinated solvent diffusion and degradation rates in sedimentary rock
We present a new field measurement and numerical interpretation method (combined termed ‘test’) to parameterize the diffusion of trichloroethene (TCE) and its biodegradation products (DPs) from the matrix of sedimentary rock. The method uses a dual-packer system to interrogate a low-permeability section of the rock matrix adjacent to a previously contaminated borehole and uses the borehole monitor

Groundwater dynamics at Kīlauea Volcano and vicinity, Hawaiʻi
Modeling groundwater inflow to the new crater lake at Kīlauea Volcano, Hawaiʻi
Hydraulic, geochemical, and thermal monitoring of an aquifer system in the vicinity of Mammoth Lakes, Mono County, California, 2015–17
Snowmelt-triggered earthquake swarms at the margin of Long Valley Caldera, California
Groundwater inflow toward a preheated volcanic conduit: Application to the 2018 eruption at Kīlauea Volcano, Hawai’i
Bioremediation in fractured rock: 1. Modeling to inform design, monitoring, and expectations
Bioremediation in fractured rock: 2. Mobilization of chloroethene compounds from the rock matrix
