Protecting Maryland's Water Supplies

Since the tragic events of September 11, 2001, MDE Water Supply Program staff have been in close communication with Maryland’s water supply systems, advising them of steps to take to protect their water facilities. A letter and informational checklist were sent to all community water systems to help them assess their vulnerability and determine actions to minimize the risk of terrorist attacks. MDE continues to update water systems with the latest developments such as security related information and FBI advisories. 

In general, Maryland’s water systems are on full alert and have already taken extra precautions such as increasing security and surveillance of key water facility components, increasing the frequency of water quality monitoring, and applying optimum treatment.

MDE, in partnership with water suppliers, will continue to work toward minimizing the risk of terrorist acts against Maryland’s water systems to ensure that our citizens continue to receive safe drinking water.
