Montgomery County, MD “boil water” map

The Gaithersburg, MD area has a “boil water” advisory; note the interesting and good use of Google Maps to show the boundaries. The image will click through to the live map.


thanks to @genehack for the pointers that led me there.

the news from the washington post:

A massive rupture in a 48-inch water main disrupted routines across large swaths of Montgomery County yesterday, forcing residents to scramble for sources of safe drinking water and prompting county officials to order about 700 restaurants not to prepare food.

    The official site is here:
    with this notice up:
    (Laurel, MD June 17, 2008): The Maryland Department of the Environment (MDE) has requested the Washington Suburban Sanitary Commission (WSSC) to conduct a second round of tests of the public water system in Montgomery County. MDE is requiring results from two consecutive rounds of tests before lifting the boil water advisory.
    The boil water advisory was issued as a precaution following last Sunday’s break of a 48-inch water main near Muncaster Mill Road and Meadowside Lane. The first round of tests results are not expected until after midnight. The second round of tests is being conducted today. It takes 24 hours to determine the results of the water sample tests. The water samples are collected from a variety of locations around the county and analyzed for coliform and appropriate levels of chlorine.
    The boil water advisory affects WSSC customers who live outside the beltway in Montgomery County. Under the advisory, customers are urged to use bottled water or to bring water to a rolling boil for one minute and cool before drinking, making ice, brushing teeth and preparing food. Customers who are unsure if they reside in the boil water area, should go to the WSSC website, to view the new interactive Google Map and to get more information see “Boil Water Advisory Information.”
    WSSC urges the public to share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.

    The water main burst on River Road this morning means a bunch of people found this page; I suspect the links above might be useful for finding out more details about water quality in general, but I don’t have any first hand details.

    Here’s the PR link:
    LAUREL, MD (December 23, 2008 ): The Washington Suburban Sanitary Commission (WSSC) is continuing to work to repair a 66–inch water main break in the Bethesda area near 8500 block of River Road. At 1:15 p.m., WSSC crews were able to shut down the main and begin restoring water pressure to the customers affected by the break. All customers in the area should have their service restored by 2 p.m.
