Drinking water and health assessment in a Northern Arizona community.

Arizona is a mineral rich state that relies on a mix of surface and ground water supplies for drinking water requirements. Small, rural water systems relying on groundwater frequently encounter elevated metal(loid) measures, particularly inorganic arsenic (As ). Such contaminant occurrences can be associated with adverse health outcomes including cancers.

Household and behavioral determinants of indoor PM in a rural solid fuel burning Native American community.

Indoor and outdoor concentrations of PM were measured for 24 h during heating and non-heating seasons in a rural solid fuel burning Native American community. Household building characteristics were collected during the initial home sampling visit using technician walkthrough questionnaires, and behavioral factors were collected through questionnaires by interviewers. To identify seasonal behavioral factors and household characteristics associated with indoor PM , data were analyzed separately by heating and non-heating seasons using multivariable regression.
