Childhood Lead Poisoning

 In 1991, the Public Health Service articulated a vision for primary prevention in Strategic Plan for the Elimination of Childhood Lead Poisoning, a departure from previous federal policy focused on finding and treating lead-poisoned children. This publication detailed a 15-year strategy for primary prevention and offered a cost-benefit analysis to demonstrate the monetized benefits of this approach. A strong national effort to follow this strategy developed but was eventually abandoned.

The organized campaign against universal screening began in California, where letters questioning the reported prevalence of elevated BLL began appearing in pediatric journals and newspapers. These letters acknowledged receiving editorial assistance from Kaiser Permanente Foundation Hospitals and argued that money spent on screening, treatment and abatement would be harmful to more worthy public health efforts. The AAP president took up this attack on universal screening as well, and efforts for universal screening were gradually eroded. 

Needleman identifies racism and the belief that lead poisoning “is a product of poor mothering, not of environmental pollution” as a driving factor shaping lead detection and prevention efforts (or the lack thereof) … “this weighting of personal choice or behavior over environment is a tool used to shift responsibility away from health authorities or polluters and onto the victim” (1875).

Overview of Formosa Drainage Study

This supplementary legal document describes recommendations for storm- and waste-water management improvements for the Formosa petrochemical plant in Calhoun County, Texas. The text is a fairly standard drainage assessment. The author describes non-trivial discharge of pollutants out of the plant’s outfalls, which drain into local waters, and the inability of the plant’s systems to prevent flooding from even small storms. For some context on this, it is pretty standard to design a stormwater system to be able to drain the 100-year storm (that is, the storm with a 1% or less chance of occurring in any given year). Formosa’s Texas plant demonstrated the inability to convey even the 2-year storm.

Emphases are mine:

“Problem areas were identified based on the results from the outfall drainage studies provided by Formosa. Thus, all the results in the OPCC rely on those studies, uncertainities associated with those studies, and the assumptions made for those studies, some of which may or may not be appropriate as I pointed out in Supplement #2 [Page 4]” (3)

“The proposed improvements assume that the conveyance capacity of the problem areas is increased 100%, which would be able to handle twice as much flow that it currently does. The results from the Drainage Study are not conclusive as to what storm event Formosa’s system currently is capable of conveying. The report does mention that the system is not capable of conveying the 2-year storm, and “sometimes” not even the 1-year storm event.” (3)

“A 45% contingency is applied to the OPCC due to the uncertainties associated with underground utilities, likelihood of existence of low road crossings and need to replace those, groundwater impacts, other unknowns, and additional costs associated with engineering, etc. 45% is reasonable and in line with industry practices in my experience, especially given the large amount of unknown information available.” (4) 

“My opinion from my July 9, 2018 report that “there have been and are still pellets and/or plastic materials discharges above trace amounts through Outfall 001” is further supported by the deposition testimony of Lisa Vitale, as representative for Freese & Nichols, Inc, that she and her colleagues have seen floating white pellets or small plastic pieces in Lavaca Bay and in the area near outfall 001 as part of her work on the receiving water monitoring program for Formosa’s TPDES permit...Ms. Vitale also testified that she told John Hyak of Formosa about these sightings as well as has sent him water samples with the pellets about five or six times, including at least one time prior to 2010. This, along with the June 2010 EPA Report I cited in my July Report, demonstrates to me that Formosa was aware of problems related to discharges of plastics from its facility since at least in 2010.” (6)

The Origami Bridge is intended to solve the problem that occur when there are mass destructions with natural disasters such as floods or earthquakes that resulted in the destroy of the local bridge. Whereas the design is aimed to substitute the local bridges with temporary bridge, furthermore to improve the transportation within the area aftermath. The design also considers the time matters during a disaster environment.

The product is designed in the way that the portable bridge can be expand from a folded mode to a bridge length takes up to across a river. It expanded in a scissor-like (90° turned scissor lift) action, then slides out the decks with end-to-end to provide platforms for vehicles.

This design is “Made of aluminum alloy and steel, it’s lightweight and easy to transport, yet sturdy enough for cars to cross.” [1]
