Maryland's point-source pollution control program has been underway since 1975. Since that time, toxic pollution in Baltimore Harbor has been notably reduced. Industrial discharges of such toxics as chromium, arsenic, copper, cyanide, zinc, and phenols are down by over 90 percent. Nonpoint-source strategies also figure prominently in toxics control. Maryland's chief nonpoint-source efforts that help control toxics include stormwater management initiatives, and incentive programs promoting agricultural best management practices.
Citizens have a vital role to play in protecting the Bay from toxics.
Awareness of this link with the Chesapeake is our first step toward protecting the Bay from toxics. Translating our awareness and concern into action is the next challenge. We do this by preventing toxics from entering our home drainage systems, and, of course, by avoiding any dumping of a toxic substance such as motor oil or antifreeze on a paved surface that leads to a storm drain. MDE is moving ahead to tighten restrictions on toxic discharges into the Bay. The department recently adopted a new set of water toxics regulations to strengthen controls over point-sources of water toxics.
