Today, El Paso is ready to take the next step in expanding its water portfolio. It is building a closed loop system that will treat sewage water and turn it directly into drinking water. Among water professionals, it's called "direct potable reuse" or "advanced purification.""It's the logical next step for us to take," said Gilbert Trejo, the chief technical officer of El Paso Water.El Paso; Orange County, California; Scottsdale, Arizona, and several other utilities across the country treat sewage water and then pump it back into the aquifer to ultimately drink. Trejo says it can take about five years for the water to filter through the ground before being pumped back out and treated to the standards of clean drinking water.This treated water is also frequently used for irrigation and industrial purposes.El Paso is building a completely closed loop facility; instead of being pumped back into the aquifer, the treated sewage water will undergo additional filtration and then be sent back into drinking water pipelines. "We see this water that's clear and it's of good quality," Trejo explained to Gupta. "The next thing for us to do is to take a high-quality water we produce at a state-of-the-art facility and then treat it a little bit more with multiple treatment processes so we can drink it."According to the EPA, the amount of wastewater produced in large cities can represent 50% to 60% of the total water supplied, providing a massive resource for cities like El Paso that are scouring for water.To make sure the water is clean of any pathogens or microbes, treated sewage water is sent through multiple steps of filtration, including UV and carbon filtration. Studies have found that treated water is, in fact, less likely to have contaminants than untreated river or lake water.Efforts by other municipalities in Texas and California to use "direct potable reuse" haven't always gotten off the ground because of the "ickiness" factor. Community buy-in is key to getting these projects launched, said Justin Mattingly of the Water Research Foundation. "These are public agencies. They belong to the public. So you might as well ingratiate the public as well."Archuelta's legacy of water conservation and education has primed El Paso for this moment."Everybody sees that we're in the desert that we're in an arid climate. Rain is scarce ... so when we tell our customers that we're doing everything possible and using every water resource around us to treat and make it safe for consumption, they take it pretty well."By 2030, El Paso Water expects that desalination will produce 10% of its water supply, and 6% will of come from advanced purification.Trejo told Gupta that it's not just the future for El Paso, it's the future for many other cities also faced with having to look for water."Technology allows us to treat [water] to a very high standard and makes it very safe to drink. Water really is all around us in every city." 2953

This abuse has left former athletes like Avery scared and angry.“Because I had buried it for so long, I had some issues,” Avery said. “It affected my family, my marriage and so, I just couldn't believe I had to face this.”Now a father of two teens, Avery hopes his story serves as a lesson.“If somebody wrongs you, you need to speak up and do something about it,” he said. “I didn't. I kept it to myself for 30 years.”Avery said he never wants to see another school use the silence of victims as a shield.“There's got to be some kind of a platform or something done out there that can say, hey, I'm going to send my kids off to school and they're going to be safe, and the school that they choose is going to take care of them, and that did not happen in this case.” 766

  

This year alone, the CDC estimates that more than 64,000 people have died of drug overdoses, most of them from opioids -- more than the number of American troops lost during the entire Vietnam War. Studies have found that using medicated-assisted treatments can reduce overdose mortality by half. 316
