The boil-water order that was announced on Saturday as a result of an interrupted by a rupture of the MetroWest Water Supply Tunnel on that same day is now lifted for all 30 MWRA communities east of Weston.
It was declared early this Tuesday that the water flowing from Massachusetts Water Resources Authority (MWRA) communities is now safe and clean again and can be used for all purposes.
Gov. Deval Patrick said that thanks to the efforts of MWRA and the whole team of state agencies the people of Boston and the neighbouring communities can once again rely on the safety of their tap water for drinking.
The boil water order for Saugus was lifted later than other communities however, because of a delay in getting back water test results. Over 800 water samples at 482 locations have been taken in affected areas and those samples have been tested by MWRA under conditions agreed-upon with the Department of Environmental Protection. The tests returns have shown no contamination that could threaten public health and so they went ahead with the decision for the boil order to be lifted.
There are guidelines however before residents use their water. People are advised to “flush” their water to clear plumbing of potentially contaminated water. Everything from building water lines including interior and exterior faucets, showers, water and ice dispensers, water-treatment units and other appliances should be flushed.
Here are the details of how to properly flush each item:
Cold-water faucets should be run with tap water until the water feels cold for 1 minute or more before drinking, brushing teeth or using the water for cooking. Also, make sure you have gotten rid of any baby formula or other foods prepared with water on the days of the boil order.
Hot Water Faucets on the other hand should be left running for 15 minutes (for a typical household 40-gallon) and the hot water tank should be left on for 30 minutes if the tank is 80-gallons or larger. Water from the “hot” faucet should never be used for drinking, cooking, or other internal-consumption purposes. After the flushing procedure, hot water is then safe to use for washing hands, and for hand-washing of dishes, pots and pans, etc. Following the flushing of the hot water pipes, Dishwashers should be run empty once.
As for refrigerators, it’s water dispensers should be flushed by at least one quart of water and ice cube dispensers should be emptied of the ice that was made during the boil-order time frame. The same goes for any ice made after 24 hours of the order lifting.
Get rid of any water used in humidifiers, Continuous Positive Airway Pressure (CPAP), oral, medical or health-care devices, and wash the device with clean water.
If you experience a lack of water pressure and/or discolored water do not worry as this is an expected result of the flushing of the lines by residents and the flushing of the hydrants. It does not pose a health risk. For further questions, contact the Marblehead Water Department, 781-631-0102.
