Global Water and Wastewater Market: $500 Billion

Report from http://www.companiesandmarkets.com/ evaluates the size of the global water and wastewater market: 

  • Membrane technology for municipal drinking water = $1.4 billion in 2011
  • Advanced disinfection = $478.5 million in 2011
  • Global water and wastewater = $400 billion to $500 billion

Changing Climate, Malaria, and Heart Failure

Haque, U., Hashizume, M., Glass, G.E., Dewan, A.M., Overgaard, H.J. and Yamamoto, T. 2010. The role of climate variability in the spread of malaria in Bangladeshi highlands. PLoS ONE 5: 10.1371/journal.pone.0014341.

These researchers examined the relationship between climate factors and malaria incidence in the highlands of Bangladesh.  No relationship was found between malaria cases and rainfall, temperature, and humidity.

Toro, K., Bartholy, J., Pongracz, R., Kis, Z., Keller, E. and Dunay, G. 2010. Evaluation of meteorological factors on sudden cardiovascular death. Journal of Forensic and Legal Medicine 17: 236-242.

Toro et al. 2010 looked for potential relationships between daily maximum, minimum and mean temperature, air humidity, air pressure, wind speed, global radiation and daily numbers of the heart-related deaths.  The study examined data pertaining to 7450 cardiovascular-related deaths in Budapest, Hungary, between 1995 and 2004.

Among other findings, global warming was not related cardiovascular-related deaths.  The authors conclude:  “with these analyses, we confirmed the results of other studies (Donaldson et al., 1998; Gyllerup, 2000; Mercer, 2003) that mortality was in inverse relation to air temperature.”

Hence, claims that global warming will result in an increase in malaria or an increase in cardiovascular-related deaths are not supported by the data.

 

USEPA Hydraulic Fracturing Study Sites Selected

USEPA is targeting seven sites for its study of hydraulic fracturing. The following two sites will be prospective studies (fracking has not yet begun):

  1. Haynesville Shale in DeSoto Parish, La.
  2. Marcellus Shale in Washington County, Pa.

The following five sites will be retrospective studies (fracking has already been conducted): 

  1. Bakken Shale in Kildeer and Dunn counties, N.D.;
  2. Barnett Shale in Wise and Denton Counties, Tex.;
  3. Marcellus Shale in Bradford and Susquehanna Counties, Pa.;
  4. a different spot in Marcellus Shale in Washington County, Pa.;
  5. Raton Basin in Las Animas County, Colo.
