Man in 'Chicagoland' wounded

• Lee McCollum Jr. was injured in a drive-by shooting on Saturday and is recovering


• The former gang member became a student leader at his southside Chicago high school


• McCollum's goal is to attend college and get out of Chicago

(CNN) -- A young man featured in the CNN series "Chicagoland" was shot this weekend on the streets of southside Chicago. Police have not released the victim's name, but friends close to him confirm it was Lee McCollum Jr.

McCollum was shot twice in the leg on Saturday morning and was treated and released from a local hospital, according to his mentor and high school principal, Liz Dozier, who was also featured on the "Chicagoland" series.

As told in "Chicagoland," McCollum's story is one of a young man who grew up in a tough part of the city but was transforming his life. He went from being a gang member to high school prom king and student leader.

McCollum has aspirations to leave Chicago and attend college, Dozier said. "The goal is still to get him to go. There's nothing for him here in Chicago."

According to the police report, the shooting happened about 7 a.m. Saturday. The 20-year-old man was standing outside when shots were fired from a white vehicle that passed by. Police are investigating and no one is in custody.

Dozier said though McCollum is not in a gang now, that doesn't mean he was a random victim. The police report states the shooting may have been gang-related.

The executive producers and directors of the series said this is part of the reality that many young people in Chicago live every day.

"Lee Jr. and other kids are growing up in a culture of hopelessness and despair, where there is a seemingly endless supply of guns," said Mark Levin, co-director of "Chicagoland."

"It's very disheartening to hear that Lee Jr. was shot. I'm relieved to hear he's out of the hospital and recovering," he said.

"This is just what Principal Dozier and others fear -- you stick around in a war zone and you get hurt."

Entire city told don't drink the water

• NEW: Test results on Toledo-area drinking water were not complete Sunday morning


• NEW: Water advisories will remain in effect until at least Sunday evening


• Tests showed microcystin, a toxin caused by algae blooms, in the water system

(CNN) -- As residents of Toledo, Ohio, waited for word on when their water will be safe to drink, Mayor D. Michael Collins said Sunday morning that tests of the water supply were going to take longer than expected. He said results would likely be available Sunday afternoon but would not provide a specific timeline.

As many as 400,000 people were told not to consume, cook with or even boil the tap water, after a toxin called microcystin was found in the water supply late Friday. Collins told reporters the advisories will remain in effect until at least Sunday evening.

He said test results so far are "trending in a very positive direction." The tests are being done by the Environmental Protection Agency.

Toledo's drinking water comes from Lake Erie, where a harmful algae bloom that causes microcystin has been growing, according to a city spokeswoman.

Several locations around the city have been designated as distribution centers for potable water, where members of the Ohio National Guard, fire officials and other first responders are giving out safe water.

Toledo to bring water for its residents

Lining up for water

On Sunday, at least one Toledo restaurant was open, despite the water issues.

The Claddagh Irish Pub brought in about 400 gallons of water from Michigan, according to Janeil Mesteller, the area director for Northwest Ohio Claddagh Irish Pubs.

According to Mesteller, the 400 gallons are for cleaning and the pub now has cases of bottled water also.

The pub will do whatever it takes to stay open and serve customers, she said. They're using disposable plastic plates and are "feeding anyone who wants to be fed," Mesteller said.

Saturday morning, a line formed outside Walt Churchill's Market & Pharmacy in Perrysburg, Ohio, before the business even opened.

Toledo-area residents, desperate for clean water, bought all the bottled water inside, market co-owner Bob Carpenter said.

Then, hearing that a water tank truck full of about 8,000 gallons had set up outside the store, more people descended on the oasis with empty jugs they could fill for $1 a gallon.

About two-thirds of the Toledo area population is affected by the water warning. Ohio Gov. John Kasich issued a state of emergency for Fulton, Lucas and Wood counties. The potential contamination also affects four municipalities in Michigan, CNN affiliate WXYZ reported.

There are no reports of anyone getting sick from the water, officials said.

Harmful algal blooms

When certain conditions are present, such as high nutrient or light levels, algae can reproduce rapidly, forming a dense population known as a "bloom," according to the National Oceanic and Atmospheric Administration

Testing is crucial because NOAA says it can't determine just from images whether blooms are toxic.

Ingestion of the toxin can affect the liver and cause nausea, diarrhea, vomiting and even acute liver failure, according to NOAA. But the Ohio state emergency management agency said it is safe for adults to shower and for everyone to wash their hands.
