Massachusetts AG Biased Against Exxon?

“In yet another stunning blow to the #ExxonKnew campaign, a federal judge today issued a discovery order against Massachusetts Attorney General Maura Healey to determine whether “bias or prejudgment” influenced her decision to initiate a “bad faith” investigation into ExxonMobil, just days after she appeared before news cameras with New York Attorney General Eric Schneiderman, Al Gore and other Democratic state attorneys general in New York.” click here

Liberal Attorneys General Pursue a Predetermined Political Stunt

This type of action simply shows how out of touch these officials are with regard to how the best available climate science develops over time as well as the dynamics of changing climates. They seem to be seeking to create a conspiracy out of thin air. 

“Massachusetts Attorney General Maura Healey is now the latest state prosecutor to start investigating conservative groups with supposed ties to ExxonMobil, after she issued a subpoena for 40 years of internal company documents and communications with a handful of think tanks.” click here

Retrospective Modeling of Water Distribution System for Exposure Assessment an Academic Exercise

Once again exposure assessment is the primary limitation of a study. So much so here that the results are simply an academic exercise. In this case “These findings should be interpreted cautiously because of the study limitations…” really means the study results have no basis in reality.

Aschengrau A, Winter MR, Vieira VM, Webster TF, Janulewicz PA, Gallagher LG, Weinberg J, Ozonoff DM. Long-term health effects of early life exposure to tetrachloroethylene (PCE)-contaminated drinking water: a retrospective cohort study. Environmental health. 2015 Apr 12;14(1):36. doi: 10.1186/s12940-015-0021-z.

Background: While adult exposure to PCE is known to have toxic effects, there is little information on the long-term impact of prenatal and early childhood exposure. We undertook a retrospective cohort study to examine the effects of their early life exposure to PCE-contaminated drinking water. This retrospective cohort study examined whether prenatal and early childhood exposure to PCE-contaminated drinking water influenced the risk of a variety of chronic conditions among adults who were born between 1969 and 1983 in the Cape Cod area of Massachusetts.

Methods: Eight hundred and thirty-one participants with prenatal and early childhood PCE exposure and 547 unexposed participants were studied. Individuals completed questionnaires to gather information on demographic characteristics, chronic conditions, and other sources of solvent exposure. The location of residences from birth through 1990 were used to estimate PCE exposure with U.S. EPA’s water distribution system modeling software (EPANET) modified to incorporate a leaching and transport model.
Results: No associations were observed between early life PCE exposure and current occurrence of obesity, diabetes, cardiovascular disease, hypertension, color blindness, near- and far sightedness and dry eyes. In contrast, a 1.8-fold increased risk of cancer (95% CI: 0.8, 4.0) was seen among individuals with any early life exposure. These results were based on 31 participants (23 exposed and 8 unexposed) who reported cancers at a variety of anatomical sites, particularly the cervix. A 1.5-fold increase in the risk of epilepsy (95% CI: 0.6, 3.6, based on 16 exposed and 7 unexposed participants) was also observed among individuals with any early life exposure that was further increased to 1.8 (95% CI: 0.7, 4.6) among those with exposure at or above the sample median.

Conclusions: These results suggest that the risk of epilepsy and certain types of cancer such as cervical cancer may be increased among adults who were exposed to PCE-contaminated drinking water exposure during gestation and early childhood. These findings should be interpreted cautiously because of the study limitations and confirmed in follow-up investigations of similarly exposed populations with medically-confirmed diagnoses. This relatively young study population should also be monitored periodically for subsequent changes in disease risk.

Drinking water quality and hospital admissions of elderly, Eastern Massachusetts

These types of studies are speculative at best and tend to be agenda-driven. The methods employed do not lend themselves to much more than hypothesis generation.

Pascal Beaudeau, Joel Schwartz, Ronnie Levin. Drinking water quality and hospital admissions of elderly people for gastrointestinal illness in Eastern Massachusetts, 1998–2008. Water Research, Volume 52, 1 April 2014, Pages 188–198

We used a Poisson regression to compare daily hospital admissions of elderly people for acute gastrointestinal illness in Boston against daily variations in drinking water quality over an 11-year period, controlling for weather, seasonality and time trends. The Massachusetts Water Resources Authority (MWRA), which provides non-filtered water to 1.5 million people in the greater Boston area, changed its disinfection method from chlorination to ozonation during the study period so we were also able to evaluate changes in risk associated with the change in disinfection method. Other available water quality data from the MWRA included turbidity, fecal coliforms, UV-absorbance, and planktonic algae and cyanobacteriae concentrations. Daily weather, rainfall data and water temperature were also available. Low water temperature, increases in turbidity and, to a lesser extent, in fecal coliform and cyanobacteriae were associated with a higher risk of hospital admissions, while the shift from chlorination to ozonation has possibly reduced the health risk. The MWRA complied with US drinking water regulations throughout the study period.

NOAA: The mean sea level trend is 2.63 millimeters/year with a 95% confidence interval of +/- 0.18 mm/yr based on monthly mean sea level data from 1921 to 2006 which is equivalent to a change of 0.86 feet in 100 years.

Noise pollution, illness attributed to wind turbines in Massachusetts

“Two wind turbines towering above the Cape Cod community of Falmouth, Mass., were intended to produce green energy and savings — but they’ve created angst and division, and may now be removed at a high cost as neighbors complain of noise and illness.”
