Ludhiana's dirty water peps up teen to find cure

LUDHIANA: A visit to the city helped a girl from Mohali to come up with a way of treating water laced with detergents. The Class XI student has made it to the final stage of the Google Science Fair, 2013. Srishti Asthana, 15, student of Science Stream of Millenium School, has been named among the top 15 finalists of the Google Science Fair, Google India, said an official statement.Such an idea clicked her during a visit to a textile industry in Ludhiana, where she saw the dyed water draining out and causing water pollution. Srishti wishes to persuade a carrier in "pure science."
Speaking to TOI, she said, "As a part of a field trip, I went to Ludhiana last year and was taken aback to see how the dyes from the textile industries got drained out in the water bodies, thus polluting it. On querying from an owner on how they treated the water before draining out, he counter questioned me on whether do we treat the detergent water before draining that out. The question triggered an idea in me of doing the same."
"I created a method where the solar light and nano particles of zinc oxide are used to treat detergent water. It is purely a green technique and environment-friendly," she added.
Srishti's father Satish Asthana, an IPS officer, said, "I am proud of my daughter. She has achieved so much at such a young age."
