Compliance

2012 Annual Compliance Report

The Compliance Section works with private labs, the Maine Health & Environmental Testing Lab, and public water systems to test drinking water quality in accordance with the Safe Drinking Water Act. The Section’s staff members review all analytical data and allocate violations to systems, which exceed the maximum contamination level or fail to test the water supply. The Compliance Section provides technical assistance on sampling or treatment techniques to public water suppliers as well as private well owners.

Compliance Officers by Region

Around February of each year, the Compliance Section generates testing requirements for all public water supplies. If you have not received a copy or you feel your schedule contains errors, please call the DWP at (207) 287-2070.
Required Testing Reports are also available online (Last Updated 4/2012)

Please remember the following guidelines when taking compliance samples:

THE LABORATORY YOU HAVE SELECTED MUST BE CERTIFIED TO PERFORM THE TESTS YOU WANT RUN ON YOUR WATER SAMPLES.

If you are operating a seasonal facility and are open for any portion of a calendar quarter, you are responsible for all water tests required for that quarter. The quarters are designated by the following dates: January 1st to March 31st; April 1st to June 30th; July 1st to September 30th; and October 1st to December 31st. A sample may be collected on any day during a given quarter.

If you are operating a seasonal facility, we are waiving any quarterly water-testing requirement for a quarter if a business closes on or before the 15th of the first month of that quarter. Please note that this waiver applies only to quarterly water tests.

Quarterly Test Waivers for Seasonal Water Systems
Your System Closes Between:
Quarterly Water Tests Waived
January 1 – January 15
January 1 – March 31
April 1 – April 15
April 1 – June 30
July 1 – July 15
July 1 – September 30
October 1 – October 15
October 1 - December 31


It is your responsibility that water test results get submitted to the DWP. The State Lab automatically sends our office test results. If you use a private lab however, make sure we get copies of your tests.

Be sure to contact Lindy Moceus before testing for Endothall or Diquat, to be sure that you are required to test for them.

Diquat, Asbestos, and MPA (Microscopic Particulate Analysis) are only analyzed in laboratories outside the state of Maine. Please contact the DWP if you are required to test for any of these contaminants.

Bacteria samples must be taken within the distribution system at the pre-approved locations you submitted on your bacteria sample site plan. No compliance bacteria should be collected at the source unless it is the only public access to the water.

For small water systems that have no treatment, the entry point sample(s) can be taken from the first tap within the distribution system.

The new list of laboratory test codes and costs for the Maine Health and Environmental Testing Laboratory is now available.

Enforcement

Enforcement Targeting Tool

Congress enacted the Safe Drinking Water Act (SDWA) in 1974 to address the contamination of drinking water sources. The Environmental Protection Agency (EPA) has the authority to establish the National Primary Drinking Water Regulations to prevent the contamination of drinking water. The rules enacted by EPA under the SDWA apply to drinking water delivered by water systems that meet the definition of a public water system.

A public water system is defined at 40 CFR 141.2, in the Code of Federal Regulations and in the Maine Rules Relating to Drinking Water at 10-144E Chapter 231 Section 2. By this definition a public water system delivers water through a set of pipes for human consumption and has at least 15 service connections, or regularly serves at least 25 residents for 60 or more days per year.

Public water systems are divided into 3 categories:

Community Water System: A public water system that serves water to the public through 15 service connections or regularly serves at least 25 people year-round.

Non-transient Non-community Water System: A public water system which regularly serves the same 25 or more people for six months or more per year. Schools, factories, industrial parks and office buildings are examples.

Transient Non-community Water Systems: A public water system that serves at least 25 people, but not necessarily the same people, for at least 60 days per year. Examples are highway rest stops, seasonal restaurants, seasonal motels, golf courses, parks, campgrounds and bottled water companies.

Under the SDWA, the EPA is authorized to establish the National Primary Drinking Water Regulations (NPDWRs) to prevent the contamination of drinking water. The purpose of the NPDWRs is to regulate contaminants that are harmful to the public health. These regulations establish both the Maximum Contaminant Level (MCL) and the Maximum Contaminant Level Goals (MCLGs). The MCL sets the limit for contamination in drinking water that a public water system may provide to the public. Failing to be under the MCL results in enforcement action by the Primacy Agency. The MCLGs is unenforceable but provides a guideline for water systems to meet.

Because the EPA has granted primacy to the State of Maine for these federal regulations, the enforcement of the SDWA is the responsibility of the State. If, however, the State fails to properly enforce the regulations, the EPA can and will step in and enforce the laws accordingly. To enforce the SDWA, Congress provides the necessary public funds to the State. The State of Maine and the EPA will continue to work together ensuring that the people of Maine have safe drinking water.
