This week we showed our interview with one of the chemists, Joel, working at Encina Wastewater Authority in Carlsbad, CA where they treat wastewater so that it can be returned to the ocean. Water samples are tested for the amount of suspended solids as it arrives at the facility and at various stages throughout the treatment process. Joel showed us how he determines the level of solids, measured in milligrams per liter, and what math he does in the process.The incoming water typically measures between 200 and 400 mg/L, and it leaves the facility at less than 5 mg/L before it heads to the ocean. That's a 99% reduction!
We also mentioned the March Madness men's college basketball tournament beginning tomorrow. 
Many organizations offer cash prizes if you correctly predict the winners of all the games (there are 63 games in the tournament). One site is offering $12 million! Are they confident they won't have to award any money? Probably! On the program, we showed the astronomical odds of correctly picking all the right winners. No one has done it yet! Here is an interactive bracket you can fill out for fun on ESPN's website.
