What We Do
The Division of Drinking and Ground Waters ensures compliance with the federal Safe Drinking Water Act and evaluates potential threats to source waters that supply Ohio's more than 4,800 public drinking water systems. The division has a lead role for statewide ground water protection in cooperation with other state and federal agencies, implements a ground water quality monitoring program and provides technical assistance to the Agency's waste management divisions.
Protect human health and the environment by characterizing and protecting ground water quality and ensuring that Ohio's public water systems provide adequate supplies of safe drinking water.
The citizens of Ohio know that their drinking water, whether it comes from wells or surface water, is safe to drink. Everyone in the state can easily obtain information about the quality of drinking water and ground water in their area, their region and the entire state.

About the Drinking Water Program
The Division of Drinking and Ground Water's (DDAGW) Drinking Water Program manages the federally delegated drinking water program and implements both state and federal Safe Drinking Water statutes and rules adopted under these laws. To carry out the program, DDAGW:
- Develops rules which match U.S. EPA regulations and are at least as stringent as the federal rules;
- Conducts inspections of water treatment plants, storage and distribution systems to ensure proper construction and operation;
- Informs Public Water Systems (PWSs) of their monitoring and reporting requirements under the law;
- Tracks systems' compliance with rules by reviewing their self-monitoring reports and the analytical results of their water sampling;
- Takes appropriate enforcement action for failure to comply with Ohio's safe drinking water laws and regulations;
- Collects and tracks data regarding various activities and reports appropriately to the federal government.
Drinking Water Staff also:
- Inspect and certify laboratories to ensure proper analysis of drinking water samples;
- Review plans for new or modified PWSs, provides technical assistance to PWSs to help them operate properly and achieve and maintain compliance;
- Evaluate water plants to determine which classification of certified operator is required to properly operate the plant;
- Administer the water and wastewater operator certification program;
- Respond to emergencies, such as chemical spills or floods which either threaten a source of water or causes a treatment plant to be out of operation;
- Respond to and investigate complaints of contaminated drinking water or water borne disease.
About the Ground Water Program
The Division of Drinking and Ground Water's (DDAGW) Ground Water Program:
- Oversees implementation of the Ohio Ground Water Protection and Management Strategy, which serves as a guide to all state programs with ground water related responsibilities to help ensure coordinated and comprehensive protection and management of the state's ground water resources;
- Manages and promotes participation in Ohio's Source Water Assessment and Protection (SWAP) Program, which helps to ensure the present and future availability of safe drinking water for public water system consumers;
- Manages the state's Underground Injection Control (UIC) Program, which regulates the types and amounts of waste that can be injected into underground geologic formations;
- Monitors through sampling and analysis the quality of ground water found in the various geologic regions around Ohio;
- Conducts specialized monitoring studies to identify ground water contamination problems, determines cause and effect relationships and recommends strategies for preventing contamination;
- Works with the Ohio Department of Natural Resources and Ohio EPA's Division of Surface Water to identify, quantify and remediate the adverse impacts on ground water caused by non-point source activities, such as feed lot operations and agricultural applications of fertilizer and pesticides;
- Administers the State Coordinating Committee on Ground Water to enhance coordination among state agencies.
Additionally, technical assistance is provided to other agency and state programs (e.g., the Division of Surface Water, the Drinking Water Program, the Bureau of Underground Storage Tank Regulations [BUSTR]), industry, public officials and the general public on various ground water programs, ground water quality, hydrogeology and other related information.
