Restricted US Entry Required to Stop the Spread of Ebola Virus

” “The potential for devastating loss of life is real,” wrote Dr. Jane M. Orient on the website of AAPS. “The disease must be stopped before there are millions of persons exposed instead of 100.” ” click here

News Article Overstates PCE Drinking Water Study Significance

This study was mentioned on this blog in a prior post. Of course, another weak epidemiology study makes alarming news headlines. Given the limitations of the methods used, even this article overstates the significance of the results, even if the alleged links are few.  Boston University is known for these types of studies on PCE with this being the latest. It seems we have long ago passed the point where such studies can provide additional information beyond what is already known about PCE. But as long as researchers need research published they will continue to be done. Why spend even more money on attempting to sharpen the point on a pencil when the pencil point is sharp enough for practical decision making?  

“”Our results suggest that prenatal PCE exposure is not associated with all obstetric complications, but may increase the risk of certain ones, including stillbirth and placental abruption [when the placenta separates from the wall of the uterus],” the Boston University Medical Center researchers said in a university news release.” click here

Removal of Sulfonylurea Herbicides from Drinking Water

Wang B, Kong D, Lu J, Zhou Q. Transformation of sulfonylurea herbicides in simulated drinking water treatment processes. Environ Sci Pollut Res Int. 2014 Oct 2.

Sulfonylurea herbicides (SUs) were detected in natural waters and could be potentially exposed to human beings via portable use. Thus, the removal of five representative SUs in simulated water treatment processes including coagulation, activated carbon adsorption, and chlorination disinfection was systematically investigated. Results showed that coagulation had little effect on the removal of the herbicides with the average removal less than 10 %. Powder-activated carbon adsorption was apparently more effective with removal rates of 50 ~ 70 %. SUs were also partially removed in chlorination process. A complete removal was achieved when the three treatments were performed in series. However, it was found that parts of the SUs were transformed into certain stable products with triazine/pyrimidine structures which might be of potential health risks in chlorination process. Thus, current drinking water treatment processes are not likely to provide sufficient protection for human population from exposure to SUs.

Surveillance of Drinking Water in Colombia

Guzman BL, Tovar GN, Bevilacqua PD.[Surveillance of drinking-water quality: assessing the degree of implementation of actions] Cien Saude Colet. 2014 Oct;19(10):4167-84.

This study aims to evaluate the Drinking-Water Quality Surveillance Programme (DWQS) implemented in Colombia. The study was conducted using methodology for assessing the implementation, integrating a normative assessment and evaluation research. For this assessment, Delphi methodology was developed that allowed the definition of an evaluation matrix, composed of 14 attributes and 62 criteria, as well as the building of a score system and parameters that permitted the evaluation of each of the defined criteria. Data collection involved conducting semi-structured interviews with institutional actors from 39 territorial units. The system evaluation showed that the DWQS in Colombia is partially implemented, with different stages of implementation in territorial units. The system showed a strengthening in actions related to data production on the aspect for improving water quality and DWQS actions from the standpoint of health promotion. However, some conceptual limitations were identified in terms of legislation thereby affecting the fulfilment of the universality of DWQS actions.

Bluff City to pay $11,960 for Violation of Drinking Water Rules

Many of the drinking water rules in the United States are cumbersome and not necessary. But even so, Cities must meet the existing rules until they are changed to something more practical.

“The Tennessee Department of Environment and Conservation ordered Bluff City to pay $11,960 last month. That decision came after Bluff City racked up three drinking water violations in the last year.” click here
