The result shown that a) the clean water and laundry water has temperature in the range of 30°C – 32° C, b) EC value of clean water is in the range of 130 - 250 µS/cm and EC value of laundry water is in the range of 310 - 440 µS/cm. Clean water is still safe for use in daily activities and laundry water is still safe to be thrown into the environment.
