Graves Elementary School in Salinas may be small, but with 32 students and four staff members, it is mighty. The school didn’t have potable water for a year because their primary water source, a well, started to fail. ”In reality, clean water at a school for students, for children is a basic necessity,” Michelle Ross, the superintendent and principal of Graves Elementary, said. Thursday evening celebrated the completion of the school’s new $200,000 well system.
