Water Testing

Wednesday, April 27th, 2011

Dr. Mark Arneson demonstrates the way he tests water for his work here in Guatemala with “Agua Potable, Analisis y Tratamiento” The water tested in this photo had a chlorine level of .24 which means it was safe to drink, but Im still unsure if I would go take a swig of water from a tap.
