Camden has the second highest cancer rate in New Jersey, and the eighth highest in the nation thanks to over 100 toxic waste sites. When the St. Lawrence Cement Company tried to build yet another polluting factory in Camden, citizens banded together and convinced a district court to halt construction. Then the Supreme Court ruled in Alexander v Sandoval that citizens could not sue based on discriminatory effect. In order to block the construction of yet another polluter, citizens would need to show that there was intentional discrimination.
