Yes, We Test Drinking Water!

Are you buying a new home or concerned about your current well water? Are you on town water but live in a old house with ancient plumbing? Give us a ring at 846-6569 to discuss your concerns!

We run drinking water tests of all kinds, including "basic safety" and common real estate panels. Testing for single elements of concern (arsenic, copper, lead, fluoride, uranium, etc.) is also welcome. See "Our Analytical Services" page for a full list of tests available.

Please note: MEL does not sell water treatment systems.

(May 6, 2018)  We are pleased to announce that we are now offering testing for Legionella pneumophila, the bacteria responsible for Legionnaires’ Disease. There is no longer any need to send your samples out of state for testing.

In June, 2017, the federal Centers for Medicare and Medicaid Services (CMS) published a memorandum titled “Requirement to Reduce Legionella Risk in Healthcare Facility Water Systems to Prevent Cases and Outbreaks of Legionnaires’ Disease.” Healthcare facilities must now develop a water management program to identify areas where Legionella could grow and spread. A critical part of the Water Management Program is monitoring the effectiveness of the plan. An easy way to monitor is to collect samples at pre-determined sampling points, and test for Legionella pneumophila.

We use a reliable test method (IDEXX Legiolert) that is comparable to the traditional culture methods. The Legiolert test gives confirmed results in seven days whereas the traditional culture methods can take up to 14 days.

Having a good water management plan will help your company meet the requirements of the CMS directive, safeguard your company’s reputation and most importantly, prevent the infection of legionellosis for vulnerable populations in your care. Trust Maine Environmental Laboratory to help you meet the monitoring requirements of your Water Management Plan.
