Epidemiological monitoring plan for geothermal developments

Area of Science:

• Environmental Science
• Public Health
• Geothermal Energy Research

Background:

• Geothermal development in the Imperial Valley necessitates environmental impact assessments.
• Previous studies lacked comprehensive baseline health data for the region.
• Potential health effects from geothermal energy extraction require thorough investigation.

Purpose of the Study:

• To establish a baseline of health status in two demographically comparable populations in the Imperial Valley prior to geothermal development.
• To identify pre-existing health differences and environmental factors, such as odor, that could influence future health impact assessments.
• To create a repeatable health effects study framework for ongoing geothermal development monitoring.

Main Methods:

• Conducted a comprehensive baseline study focusing on health effects in the Imperial Valley.
• Selected two distinct populations for comparison: one potentially affected by geothermal development and one less likely to be affected.
• Documented general health attributes and specific attributes susceptible to adverse effects from geothermal activities.
• Assessed current presence and intensity of odors in the study areas.

Main Results:

• Identified pre-existing differences in health status between the two selected populations.
• Confirmed the current presence of intense odors, a potential issue linked to geothermal development.
• Established a baseline against which future health changes can be measured.

Conclusions:

• Baseline health data is essential for accurately attributing future health changes to geothermal development.
• Existing odor issues must be considered to avoid misattributing them to new geothermal activities.
• This study provides a critical foundation for ongoing environmental and health monitoring of geothermal projects in the Imperial Valley.
