“…Phosphate sand grains and nodules originating in the Peace River Member of the Hawthorn Group in central Florida have been reworked and incorporated into younger geologic units in southern Florida [4,16,32,34,44,45], including a number of Pliocene and Pleistocene age units in Sarasota, Charlotte, Lee, Hendry, Martin, Palm Beach, Broward, and Dade counties. The reworked phosphate and some organic sediment accumulations, and associated anomalously uranium and radium-226 concentrations, have caused the occurrence of higher than background radioactivity levels in some areas, particularly in Sarasota and Lee counties and perhaps in Palm Beach County [45].…”

“…Southern Florida contains naturally occurring radioactive substances in rocks, soils, groundwater, and indoor air at various concentrations [4,5,6,7,8,9,10,11,12,13]. In addition, radioisotopes associated with atmospheric testing of nuclear weapons have accumulated in the soils and sediments of southern Florida and sometimes are mobilized into groundwater [14,15,16]. While radioactively in the soils and sediments of a carbonate platform is normally quite low, southern Florida may be an exception which should be of interest to the international community because background testing should be done even in areas where radioactively is not expected to occur.…”

Southern Florida is underlain by rocks and sediments that naturally contain radioactive isotopes. The primary origin of the radioactive isotopes is Miocene-aged phosphate deposits that can be enriched in uranium-238 and its daughter isotopes. Nodular phosphate containing radionuclides from the Miocene has been reworked into younger formations and is ubiquitous in southern Florida. When the nodular phosphate is exposed to groundwater with geochemical conditions favorable for its dissolution, uranium, radium, and radon may be released into the groundwater system. Uranium concentrations have been measured above the 30 µg/L drinking water standard at only one location in Lee County. Radium226/228 exceedances of the drinking water standard have been documented in numerous wells in Sarasota County. Indoor radon activities have exceeded the 4 piC/L guideline in five southern Florida counties. The exceedance of radioactivity standards in drinking water does not occur in municipal drinking water supplies, but rather only in some domestic self-supply wells. Health risks for exposure to radiation from domestic self-supply wells could be mitigated by testing of well water and, if necessary, switching to the use of a different aquifer or treatment process. While the risk of exposure to radon in indoor air in southern Florida is generally low, some areas are enriched in soil radon that migrates into structures, which could be addressed by improved ventilation.

Climate effects on US infrastructure: the economics of adaptation for rail, roads, and coastal development

Changes in temperature, precipitation, sea level, and coastal storms will likely increase the vulnerability of infrastructure across the USA. Using models that analyze vulnerability, impacts, and adaptation, this paper estimates impacts to railroad, roads, and coastal properties under three infrastructure management response scenarios: No Adaptation; Reactive Adaptation, and Proactive Adaptation. Comparing damages under each of these potential responses provides strong support for facilitating effective adaptation in these three sectors. Under a high greenhouse gas emissions scenario and without adaptation, overall costs are projected to range in the $100s of billions annually by the end of this century. The first (reactive) tier of adaptation action, however, reduces costs by a factor of 10, and the second (proactive) tier reduces total costs across all three sectors to the low $10s of billions annually. For the rail and road sectors, estimated costs for Reactive and Proactive Adaptation scenarios capture a broader share of potential impacts, including selected indirect costs to rail and road users, and so are consistently about a factor of 2 higher than prior estimates. The results highlight the importance of considering climate risks in infrastructure planning and management.
