Plant Water Management in Microgravity
CSS was selected by NASA through its REMIS contract to serve as payload developer, performing mission integration and operations to advance the fundamental research to a higher Technology Readiness Level.


The Plant Water Management (PWM) project demonstrates the concepts of adequate hydration and aeration to a plant’s root zone in a microgravity environment to sustain plant life from germination through harvest. PWM capitalizes on physics and geometry that is functional in both a normal and microgravity environment to deliver water and nutrients.
CSS was selected by NASA through its REMIS contract to serve as payload developer, performing mission integration and operations to advance the fundamental research to a higher TRL (Technology Readiness Level). CSS supported the PWM principle investigator in developing the science and engineering requirements that served as the blueprint for developing the 3,4,5 and 6 series of hardware delivered to the International Space Station (ISS) for demonstration.
Additional Projects

Audit and Inspection Support for the National Institute of Environmental Health Sciences (NIEHS)
For more than 35 years, CSS has provided quality control assessment support to the National Toxicology Program (NTP) on studies relating to the toxicological effects of chemicals in the environment.

Analytical Chemistry Support for the US EPA National Aquatic Resource Survey
CSS chemically analyzes hundreds of water samples collected annually from the US EPA’s National Aquatic Resource Survey (NARS), a critical contribution to the EPA assessments of the condition of the nation’s water bodies.

Analytical Support for the Drinking Water Emergency in Flint, Michigan
Helping 100,000 Residents Affected by Elevated Lead Levels in Local Water Supply Lead contamination found in the drinking water in Flint, Michigan had a catastrophic impact on the community and its residents. CSS supported EPA’s response to the crisis by providing mobile and fixed analytical laboratory services and data review. Over a nine-month period, our…
