FLINT (WJRT) (3/9/2018) - Professors from the University of Michigan and Wayne State University say steps taken to get lead out of Flint's tap water are working.

They say their most recent data shows filters attached to faucets are removing the lead. Nancy Love with U of M said residents and businesses still need to take precautions and maintain the filters.

Love said the filters tend to lose their effectiveness over time toward protecting against bacteria, so it is vital for people to change those cartridges about every two to three months.

Dr. Mona Hanna Attisha, who broke wide open the investigation of lead in Flint's water, said optimistically the city could be lead free in the next four years.

She cautioned there is still plenty of work ahead for years if not decades to fully recover from the water crisis, including providing services to children who were exposed to excessive lead levels.

Attisha said the city has come a lot way since her findings about lead in the water came out almost three years ago. She graded the city just above average on the level of response.

"I feel like a B+ or B-, B+ on the rise," Attisha said. "So, we need to do some extra credit and we need to continue to work hard and I think the trajectory is forward."

She started a new study in February and has started enrolling children around the age of 5. In this study she'll be looking at baby teeth as children lose them, which will give an accurate picture of past lead exposure.
