The district is also taking steps to bring on additional vendors to take away trash.

J.P. Mascaro & Sons told Eyewitness News it was suffering from a “perfect storm” this week, with move-in, extreme weather, and labor issues.

They say they are working aggressively to resolve the situation, and made additional pickups at those schools on Friday.
