Comprehensive Industrial Hygiene Labs (CIHL)

Purpose and Function

Ms. Mary Joy Dumaran, Chemist, prepares samples for analysis of metals

NMCPHC operates two CIHLs; one is located in Norfolk, VA and the other is in San Diego, CA. The labs provide analysis of samples collected under the technical direction of U.S. Navy Industrial Hygienists to identify and quantify occupational exposures of U.S. Navy and U.S. Marine Corps personnel, both military and civilian, to chemical substances.

The CIHLs also analyze biological samples submitted by occupational health physicians and nurses for determination of lead, cadmium and mercury in blood and urine.

The CIHLs do not analyze samples for air pollution and water pollution under EPA jurisdiction nor do they analyze environmental samples for bacteria and fungi collected as part of an Indoor Environmental Quality investigation. For environmental analysis under U.S. EPA and state permits, please contact your local NAVFAC Environmental Office. The results of sample analyses are reported within 12 working days of sample receipt to the occupational health professional submitting the sample. That occupational health professional subsequently uses the analytical results to calculate, interpret and report potential occupational exposure.
