About Baltimore Water Systems by My Home Water System

Baltimore Water Systems helps Baltimore homeowners compare water treatment options and request a written quote from one qualified local company. The request form names that company before you submit.

Baltimore Water Systems is run by My Home Water System, operated by Aidren LLC. We are not a water utility and are not affiliated with Baltimore City DPW (Montebello laboratory) or Baltimore City DPW (Ashburton laboratory).

Where do the water figures come from?

Every figure is copied from the utility's own published report or web page, with its period and a link. We do not test water and do not estimate figures. Sources were last checked October 27, 2026.
