Dry periods are becoming more frequent in Maine, with some parts of the state experiencing unusually dry or drought conditions almost annually. To help Public Water Systems maintain service and quality, the Maine CDC Drinking Water Program (DWP) continues to provide updates and resources on the drought situation.

Drinking water sources are vulnerable to contamination whether it be from harmful chemicals or biological organisms (such as bacteria and viruses).

Hydrogeology is the study of groundwater -- water found below the surface of the earth. Believe it or not, about half of Maine's homeowners are practicing hydrogeologists, because they have, with the help of a well driller, explored for, found, and are actively utilizing groundwater. These homeowners derive their drinking water from private water wells located on their property. All of these wells, regardless of the type or depth, get their water from groundwater.

Violations

Violations are issued when a public water system does not meet all of the requirements mandated by the Safe Drinking Water Act or the Maine Rules Related to Drinking Water.

Treatment systems are mechanical and/or chemical processes that remove contaminants from water, ensuring it is safe for consumption. Treatment systems are an important part of delivering safe drinking water for many public water systems throughout the state. However, treatment only works when the proper chemicals are used in the right amounts, and treatment is maintained and monitored. Failure to regularly and effectively maintain and monitor your treatment system puts the health of your customers at risk.

Before modifications are made to any existing public water system in a manner which may affect the quality of water produced, that system must submit an application detailing the proposed changes to the Drinking Water Program for approval.

Before construction of a new public water source is initiated, proposed plans must be submitted to the DWP for approval. (22 M.R.S. §2612)

Step 1: Preliminary Approval

Before a new well is drilled, the selected site must be approved by the Drinking Water Program. The State of Maine Rules Relating to Drinking Water establishes a set-back for all wells of at least 300 feet from any potential sources of contamination (such as fuel tanks and leach fields). If site conditions so require, a waiver of this setback requirement may be requested.

Per- and polyfluoroalkyl substances (PFAS) are human-made chemicals that have been widely used since the 1940s in consumer products and industrial applications. Due to their widespread use and persistence in the environment, most people in the United States have been exposed to some level of PFAS. There is evidence to suggest that continued exposure above specific levels to certain PFAS may lead to adverse health effects.
