WATER INFORMATION CENTER

The Maryland Department of the Environment (MDE), Water Management Administration’s (WMA) mission is to protect the public health and the aquatic environment by carefully managing Maryland's surface and groundwater resources, maintaining safe and reliable drinking water supplies and wastewater treatment systems and restoring and preserving Maryland's water and wetlands through efficient and effective implementation of state and federally mandated pollution control and resource management programs.

WMA implements diverse regulatory and planning programs to maintain the quality of ground and surface waters of the State.  Maryland’s water quality standards provide that surface waters should be protected for basic water uses such as water contact recreation, fishing, support of balanced and diverse populations of aquatic plants, animals, and wildlife, and use as agricultural and industrial water supply.  Reduction of nutrients from point and nonpoint sources, control of bacterial pollution from sewage treatment plants, and toxic materials from any source are the focus of these permits. Maintaining these standards requires the issuance and enforcement of controls and permits on point and nonpoint sources of pollution.

Under federal and State regulations, MDE is also responsible for ensuring that all public drinking systems throughout Maryland meet strict drinking water quality standards.  Public drinking water systems serve approximately 4.3 million Marylanders.  Private wells serve approximately 900,000 Marylanders.  Through delegation from MDE, local governments regulate individual wells that serve one lot or home.

Bay Restoration Fund
The Bay Restoration Fund is a dedicated fund, financed by wastewater treatment plant users, that is used to upgrade Maryland’s wastewater treatment plants with enhanced nutrient removal (ENR) technology so they are capable of achieving wastewater effluent quality of 3 mg/l total nitrogen and 0.3 mg/l total phosphorus.  In addition, a similar fee paid by septic system users is utilized to upgrade onsite systems and implement cover crops to reduce nitrogen loading to the Bay.  

Water Quality Financing 
The mission of the Water Quality Financing Administration (WQFA) is to assist in the financing of capital infrastructure costs for wastewater and drinking water projects.  

Fish and Shellfish 
MDE’s Fish and Shellfish programs monitor the quality of shellfish harvesting waters, and testing edible fish tissue to certify that fish are safe for human consumption.  Certain fish in contaminated waters can accumulate high enough levels of toxic substances.  When consumed frequently over a lifetime these may increase the consumers’ risk of adverse health effects.  In these cases, MDE issues fish consumption advisories to limit consumption of certain fish species.  MDE also works with the county health departments to monitor water quality in Maryland beaches

Environmental Boards
The Environmental Boards are comprised of three State licensing boards, established by the General Assembly. Also located within the Water Management Administration, the Boards were created to license and certify individuals as environmental sanitarians; superintendents and operators of waterworks, wastewater works, industrial wastewater works, wastewater collection systems and waste water distribution systems; and well drillers, water conditioner and water pump installers.  

Flood Hazard Mitigation
MDE’s flood mitigation program works with communities in finding ways to reduce or eliminate risks to safety and property.  Most importantly, MDE assists communities in establishing sustainable floodplain management programs to prevent future flooding risks from occurring. 

Mining in Maryland
The mission of the Mining Program is to protect the public and the environment from the potential impacts of active mining; and to promote the restoration and enhancement of active and abandoned mine land and water resources.  This program provides information on mining in Maryland from regulatory permitting to abandoned mine reclamation.  It also provides water quality data and historical perspectives related to mining in Maryland. 

Sediment, Stormwater and Dam Safety
The Sediment, Stormwater and Dam Safety Program concentrates on controlling runoff increases and mitigating water quality degradation associated with new development.  This section provides guidance on how to prevent sediment and stormwater runoff, or “nonpoint source” pollution.  It also provides an overview of Maryland’s dam safety program, which assures that all dams in Maryland are designed, constructed, operated, and maintained safely to prevent dam failures and the consequences of failures. 

Water Management Permits
MDE’s Water Management Administration (WMA) issues permits to protect Maryland’s water resources by controlling industrial and municipal wastewater discharges.  Surface water discharges are regulated through combined State and federal permits under the National Pollutant Discharge Elimination System (NPDES).  Groundwater discharges are regulated through State issued groundwater permits.  Also related to the protection of groundwater is the coordination will all local health departments for the regulation of individual wells and septic systems. 

Water Quality Infrastructure 
The Water Quality Infrastructure Program (WQIP) is responsible for the development and implementation of capital projects to correct public health and water quality problems and provides restoration measures that lead to water quality and habitat benefits.  WQIP provides technical and financial assistance to local government and eligible private entities. 

Water Supply
MDE’s Water Supply Program implements various programs to ensure that public drinking water systems provide safe and adequate water to all present and future users in Maryland, and that appropriate usage, planning and conservation policies are implemented for Maryland’s water resources.  This mission is accomplished through proper planning for water withdrawal, protection of water sources that are used for public water supplies, oversight and enforcement of water quality monitoring at public water systems, regular onsite inspections of water systems, and prompt response to water supply emergencies.  

Wetlands and Waterways
MDE's Wetlands and Waterways Program is responsible for the protection and management of Maryland’s tidal and nontidal wetlands and waters.  The Nontidal Wetlands and Waterways Division regulates activities conducted in nontidal wetlands and their buffers, and nontidal waterways, including the 110-year floodplain.  The Tidal Wetlands Division regulates activities conducted in tidal wetlands.  In addition to its regulatory responsibilities, the Program also creates, restores, and enhances nontidal wetlands and streams, provides training and technical assistance and assists in the development of watershed management plans. 

TMDL
Total Maximum Daily Loads (TMDLs) are a requirement, found in §303(d), of the federal Clean Water Act that became law in 1972.  TMDLs are a tool for implementing State water quality standards.  They are based on the relationship between pollution sources and in-stream water quality standards

Compliance
MDE staff are always on call during the regular workweek and on weekends, holidays and after normal working hours, to ensure that all environmental emergencies are promptly addressed.  You may report any environmental emergency that poses an immediate threat to the public health or the well-being of the environment such as oil and chemical spills or accidents causing releases of pollutants by calling toll free (866) 633-4686.
