New Jersey Student Nishita Sinha wins the 2016 U.S. Stockholm Junior Water Prize!

Nishita Sinha resizedNishita Sinha, a rising senior at Chatham High School, Chatham, NJ is the recipient of the 2016 U.S. Stockholm Junior Water Prize for her project, Experimental Studies in Developing Safe Sanitation Solutions.  Worldwide, 2.4 billion people lack access to in-home toilets, hampering health and development. Cramped living spaces without plumbing make traditional toilets infeasible in poor countries. Significant strides have been made towards economic alternatives. One promising option is a 2-pit composting toilet, 61 of which have been installed in a village in India. In this toilet, solid waste is effectively treated through anaerobic composting. Concerns remain regarding the impact of liquid waste on drinking-water. | Click here to read more of Nishita’s paper.

Sinha was awarded $10,000 and an all-expenses paid trip to represent the U.S. at the SJWP international competition in Stockholm, Sweden, during World Water Week in late August.
