Action against Arsenic


In January, Nuevas Esperanzas started a new project to provide families from five rural communities with filters to remove the arsenic from their drinking water.  (The arsenic is naturally occurring.  See my reply to Ben Sadler's comment below for an explanation.)  Last year Nuevas Esperanzas coordinated a health study which found that these families were ingesting significant amounts of this poison in their drinking water.

People drinking water contaminated with arsenic will not usually get sick immediately.  However, ingesting high levels arsenic can significantly increase the long-term risks of serious illnesses.  People regularly drinking water with more that 50 ppb (parts per billion) of arsenic may be at one hundred times greater risk of cancer later in life, for example. 

With the filter project the hope is to accomplish two things.  First, we want help some of the most affected families from the study clean up their water right away.  Second, we want to test to see if these filters could be applied more widely.  Unfortunately in appears that arsenic contamination could potential problem not only for these communities but also for communities throughout the entire region.

Nuevas Esperanzas finished building the filters last month and finished them to the families just last week.  The slideshow shows the training session that was provided before setting up the filters in each home, to explain where the arsenic was coming from, how the filters are built, and how they clean the water. 

If you’re interested in learning more about this there are articles on the NE website about how the filters are built and how they work, as well as about the clinics where the data was collected for the health study

  1. What a blessing to serve by helping a community to have clean water! Do you mention anywhere why there is arsenic in the water? I was searching around for that info and I couldn't find it. Blessings to you!

    1. I didn't mention it, although maybe I should have. The arsenic in this case is naturally occurring. Arsenic is a mineral, and it is not unusual to find it in rocks and soils, but it typically isn't released into the ground water (mobalization). However, arsenic can be mobilized when the ground water is very hot, which is the case near the volcanoes where these communities are. So in this case the arsenic contamination is the volcano's fault.
