This is a ship manifest detailing the 290 Chinese colonists expected to arrive in Cuba aboard the Portuguese ship "Gica." The ship arrived in the port of Havana on March 8, 1864, with 281 of the colonists listed in the ship manifest; seven died during the journey and two remained in Macao.

In September 2005, some concerned Walker residents contacted the Arizona Department of Health Services in regards to the quality of groundwater in the area. The residents petitioned ADHS to perform well water tests to determine the character of the water, and whether there is any potential health risk associated with consuming or using the water. In response to the concerned community members and in agreement with the Agency for Toxic Substances and Disease Registry, ADHS collected water samples from the site and completed a health consultation. This health consultation evaluates if the levels of lead and other metals in the private wells in Walker area pose any adverse health effects.

In March 2004, a resident of Cornville contacted the Arizona Department of Environmental Quality to request information on arsenic in drinking water. The resident collected six well water samples from their own well and neighbors’ wells and submitted them to a private laboratory for arsenic analysis. The analyses detected arsenic ranging from 15 to 952 μg/L. ADEQ and the community members asked the Arizona Department of Health Services to provide health information about using the water. Initial conversations with the well owner and other community members revealed that many people had concerns about potential health effects from arsenic exposure.

In March 2004, the U.S. Environmental Protection Agency requested information on efforts to monitor and protect children from exposure to lead in drinking water at schools. The Arizona Department of Health Services reviewed the state lead poisoning registry, and analyzed drinking water samples from 45 randomly selected schools. The Office of Environmental Health provided this consultation to help document our findings and supplement our response to the EPA. This work was also undertaken to help provide useful information should hazardous waste sites be discovered in the future near these schools. We also wanted to apply the ATSDR health assessment process in support of state and federal efforts to protect the health of children.

In September 1999, the U.S. Environmental Protection Agency contacted the Arizona Department of Health Services, Office of Environmental Health, concerning potential contamination of private drinking water wells along Lynx Creek in the Walker, Arizona, mining district. Historical mining activities in the area might have resulted in contamination of groundwater by acid mine runoff as well as metals from extraction processes. EPA and ADHS determined the historical mining activity had caused environmental damage and the potential for adverse human health impacts. ADHS initiated a private well sampling program to determine if the mining activity has had an adverse impact on the quality of water from these wells. Several area residents have expressed concerns about their water quality. The objective of this public health consultation is to evaluate the potential for health effects from exposure to contaminants in private drinking water wells in the Walker, Arizona area.
