Residents along Alabama's Gulf Coast are being asked to participate in a survey designed to gauge long-term effects of the 2010 Gulf oil spill. Representatives of the state Department of Public Health will go door-to-door this week to conduct the survey, which take about 15 minutes to complete. Residents of Mobile and Baldwin counties were also surveyed in 2010 and 2011. Participants also will be asked about how their community is prepared for an emergency and their access to health care. The information will be analyzed by the health department in conjunction with the Centers for Disease and Prevention and Alabama Department of Mental Health. Representatives will carry identification and be able to provide a phone number if someone wants to verify who they are. Copyright 2012 The Associated Press.
