Description: This drinking water disinfection health intervention took place from 2004-2006 and evaluated the use of SODIS program for rural residents in Rovieng district, Preah Vihear province, Cambodia. The program studied SODIS as it relates with good hygiene and sanitation among rural households who normally drink water directly from rivers or wells without treatment. The project outcomes were adoption of the SODIS techniques among villagers and expansion of the project to three additional provinces under the direction of ADRA Cambodia.

Title: The Eastern Coachella Valley Environmental Health Study
Description: This participatory research focuses on community-identified environmental contamination and potential human health effects. The project contains a large set of research questions which will provide evidence for long term policy and development of this underserved community. The research is IRB approved, has a rigorous sampling procedure and uses only on-the-ground interviews conducted by trained local promotoras. The survey questionnaire uses several national health metrics to assess topics such as asthma, depression, crowding, air and water quality topics. The home assessment tests water, air, hygiene practice and home appearance to assess physical contaminant exposure. Concentrated research questions detail exposure to pathogens from water and soil in disadvantaged communities.

Title: Disadvantaged Community (DAC) Outreach Demonstration Project
Description: This project engaged Disadvantaged Communities (DAC) to participate in California’s Integrated Regional Water Management (IRWM) planning process for the Coachella Valley. The aim was to activate disadvantaged groups that have traditionally been left out of the IRWM processes. The project used qualitative community mapping techniques along with an in-person survey questionnaire on water and sanitation. The research is complimentary to the PI’s research direction by funding the first participatory community map of the region and promoting awareness of water and wastewater issues among the population. The project recommended proceeding for funding in three priority areas of on-site alternative wastewater treatment, point-of-use water treatment and extension of existing water and wastewater infrastructure. See the team’s output reports here.
