The state has issued $186 million in bonds to help the Chesapeake Bay by financing wastewater-treatment and sewer-system infrastructure and upgrades statewide. According to Gov. Timothy M. Kaine’s office, the Virginia Resources Authority total investment in bay cleanup in the past two years exceeds $810 million. “The commonwealth has dedicated more than $1 billion to cleaning up the Chesapeake Bay since the start of my term, and we have made fighting pollution one of our core concerns,“ Kaine said in a statement announcing the bonds.
