PTRSOLAR indicates whether the respondent said, in response to an open-ended question, that solar disinfection is something that can be done to make water safe to drink. Solar disinfection refers to placing water in transparent plastic bottles and exposing the filled bottles to full sunlight for at least 6 hours. The UV-A radiation from sunlight destroys pathogens in the water.
The information in PTRSOLAR is taken from the household record, linked to the record of the woman respondent. This information applies to household residents, not temporary visitors, so researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2").
