Problem Statement:
Lead is one of the most dangerous contaminants in drinking water. Some lead compounds found in drinking water are very toxic, leading to various illnesses and diseases. This colorless, odorless, and tasteless metal can go undetected in water. Excessive amounts of lead place adults at higher risk for cancer, stroke, kidney disease, memory problems, and high blood pressure. Lead can cause seizures, hearing loss, behavioral problems, brain damage, learning disabilities, and a lower IQ level in children.

About the Innovation:
Young inventors from DiscoverSTEM designed a small but very effective system to quickly and easily detect lead and other impurities in water. The innovation consists of a water chamber to put water to be tested and reactant capsules or pods that release minute quantities of reactants in the water, thus detecting the presence of lead and impurities.

DiscoverSTEM founders Mirza Rizwan and Mirza Faizan have made history by becoming the first Indian to win the coveted George Washington Honor Medal from the Freedoms Foundation – USA.

Started in 1949 by former US President Dwight D. Eisenhower, Freedoms Foundation honors exceptional contributions of Americans towards communities in the USA. Generally reserved for the US citizens, the awarding organization made an exception to recognize the stellar research work and its impact of India’s Mr. Rizwan in designing and implementing a unique STEM & Innovation program for American children, thereby revolutionizing the education system in the USA.

Few of the other notable non-US citizens who have received George Washington Honor Medal include Ms. Margaret Thatcher (Former Prime Minister of United Kingdom), Lech Walesa (Former President of Poland and Noble Prize winner) and world-renowned Russian writer Aleksandr Solzhenitsyn. As the latest recipients of this prestigious honor, Mirza brothers join historically acclaimed group of citizens whose work and dedication advance the American ideals, the award letter says.

Some of the distinguished US citizens who have received this award for their stellar contributions in their field are Walt Disney, Astronauts Sally Ride and John Glenn, Capt. Sully Sullenberger, Athletes like Arthur Ashe, George Foreman and Tiger Woods and famous US educator Jaime Escalante.
