Rio Rancho, NM to spend $9 million on wastewater reuse

Rio Rancho drilled a 2,000 foot well into their aquifer water source.  Wastewater will be cleaned to drinking water standards then re-injected back  into the aquifer. For only $9 million. Residents are on board with water conservation, but will reuse of toilet water pass the customer smell test? ….click here for more…

 

 

Pflugerville, Texas goes after its private water system

The Pflugerville City Council wants its water system…..so what if it is owned by a private company. The city will move forward with plans to acquire the jurisdiction of water and wastewater provider Windermere Utility Co, which is owned by Southwest Water Company. If negotiations to purchase the water system fail, then the city will seize the water and wastewater utility by eminent domain…..so there!   Click here for news coverage….

Bangladesh – Citizens have the right to water…

The Banglaesh government has drafted a water law recognising access to safe water is a basic right. The government intends to hand over services like drinking water supply and sewage management to profit-seeking private sectors. Will this deprive citizens of the right to water? Click here

Press Spin: OU Campus paper misleads readers on chromium 6

USEPA has announced a schedule for updating the chromium 6 risk assessment in the IRIS database….click here.

Contrary to what is claimed in this University of Oklahoma (OU) campus paper (click here), this is not an effort to re-evaluate standards. First, the chromium 6 risk assessment must be updated based on the latest available science.   USEPA anticipates that the draft assessment for hexavalent chromium (oral and inhalation) will be released for public comment and external peer review in 2013.

Then, the USEPA Office of Ground Water and Drinking Water has stated (click here) that it “will carefully review the conclusions and consider all relevant information to determine  if a new standard needs to be set.” Click here.

In addition, the Environmental Working Group is an environmentalist advocacy organization, not a research organization. Political groups such as the Water Research Foundation (formerly the AWWA Research Foundation) are governed mostly by advocates from large city water systems and large firms. To avoid being perceived as being like the tobacco industry they usually support the statements of environmental groups, at least on the surface, rather than basing statements on science.

Canadian tap water consumption, bottled water use

This study finds drinking water intake to be less than in the United States.

Roche, S.M., Jones, A.Q., Majowicz, S.E., McEwen, S.A., and Pintar, K.D. Drinking water consumption patterns in Canadian communities (2001-2007). J Water Health.  2012 Mar;10(1):69-86.

A pooled analysis of seven cross-sectional studies from Newfoundland and Labrador, Waterloo and Hamilton Regions, Ontario and Vancouver, East Kootenay and Northern Interior Regions, British Columbia (2001 to 2007) was performed to investigate the drinking water consumption patterns of Canadians and to identify factors associated with the volume of tap water consumed. The mean volume of tap water consumed was 1.2 L/day, with a large range (0.03 to 9.0 L/day). In-home water treatment and interactions between age and gender and age and bottled water use were significantly associated with the volume of tap water consumed in multivariable analyses. Approximately 25% (2,221/8,916) of participants were classified as bottled water users, meaning that 75% or more of their total daily drinking water intake was bottled. Approximately 48.6% (4,307/8,799) of participants used an in-home treatment method to treat their tap water for drinking purposes. This study provides a broader geographic perspective and more current estimates of Canadian water consumption patterns than previous studies. The identified factors associated with daily water consumption could be beneficial for risk assessors to identify individuals who may be at greater risk of waterborne illness.
