Customers on Dover Court are advised to bring water to a rolling boil for one minute and allow cooling before drinking it or using it for ice cubes, washing vegetables and fruit and for brushing teeth.
New Jersey American Water also recommends the following steps in a release issued Thursday night: – Throw away uncooked food or beverages or ice cubes if made with tap water during the day of the advisory; – Keep boiled water in the refrigerator for drinking; – Rinse hand-washed dishes for a minute in diluted bleach (one tablespoon of household bleach per gallon of tap water) or clean your dishes in a dishwasher using the hot wash cycle and dry cycle.
– Do not swallow water while you are showering or bathing; – Provide pets with boiled water after cooling; – Do not use home filtering devices in place of boiling or using bottled water; most home water filters will not provide adequate protection from microorganisms; – Use only boiled water to treat minor injuries.

WESTERLY, R.I. — Health officials have issued a boil water notice in Westerly, Rhode Island after E. coli bacteria was found in the water supply.
The state Department of Health said Wednesday that water customers should boil water used for human consumption — including drinking and cooking — for at least one minute.
Customers can also use bottled water.
E.coli is bacteria that signal the presence of fecal matter.
It was detected in a routine sample taken on Monday.
E.coli can cause diarrhea, cramps, nausea, headaches or other symptoms.
The bacteria poses an increased health risk for infants, young children, the elderly, and people with severely compromised immune systems.
Even with the boil-water advisory in place, all Westerly Public Schools will remain open on Thursday, CBS affiliate WPRI reports.
Resident Courtney Capizzano said she ran out to the store for bottled water immediately following the boil water order.
"We have dogs at home, babies at home.

A boil-water notice has been issued for Westerly Water Department customers because of contamination by E. coli bacteria, according to a news release from the Rhode Island Department of Health.
A boil-water notice has been issued for Westerly Water Department customers because of contamination by E. coli bacteria, according to a news release from the Rhode Island Department of Health.
Customers are advised to use bottled water or to boil vigorously for at least one minute all water used for human consumption, including drinking, food preparation, cooking, making ice, brushing teeth and washing dishes.
Boiling kills bacteria and other organisms in the water.
Infants and young children should not be bathed in unboiled water because they could swallow it accidentally.
The advisory will remain in effect until the Water Department has treated the system to restore bacteria counts to acceptable levels.
The presence of E. coli bacteria indicates that the water may be contaminated with human or animal wastes.
The Westerly Water Department sells water to customers throughout the Town of Westerly and to customers in Pawcatuck, Connecticut.
Samples will be collected throughout the distribution system on Thursday, Nov. 16, to determine the extent of the contamination, and sample results will be available Friday.
For more information, call the Westerly Water Department at (401) 348-2561.

The boil water advisory for approximately 100,000 Pennsylvania American Water customers in southern Allegheny and Washington counties that began Monday night because of cloudy tap water will last at least until Wednesday morning, but may extend into the afternoon.
Ms. Walters said the cause of the turbidity problem that prompted the precautionary advisory in 55 municipalities was a malfunctioning filter at the company’s Aldrich Purification Plant on the Monongahela River in Union Township, Washington County.
The water supplier must pass two turbidity tests taken a day apart before the boil water advisory can be lifted.
Turbidity, or cloudiness of water, does not make water unsafe to drink, but it may interfere with disinfection and allow for growth of viruses, bacteria, and parasites, the water company acknowledged on its Webpage Tuesday.
Those “bugs” can cause a variety of health problems, including nausea, cramps, diarrhea and headaches, especially affecting people with compromised immune systems, the elderly and infants.
Ms. Walters said no tests done so far show contamination by any of the disease-causing organisms.
However, as a precaution, the company is advising customers in the affected areas to bring all water to a boil for one minute or use bottled water.
Pennsylvania American has two water intakes on the Monongahela River, Becks Run, located in Baldwin Borough, Allegheny County, and the Aldrich intake, approximately 21 miles south of Becks Run in Union Township, Washington County.
The water from that intake is pumped two miles to PAWC’s Hays Mine Purification Plant in Baldwin Borough, Allegheny County before it is distributed to customers.
PAWC states on its Webpage that it will inform customers “when tests show no bacteria and you no longer need to boil your water.” For more information, visit the PAWC Web site at www.pennsylvaniaamwater.com, and select Alerts Notification, or contact Pennsylvania American Water’s customer service center at 800-565-7292.

PITTSBURGH (KDKA) – Water cooler conversation had a different meaning in Bethel Park Tuesday, as customers of Pennsylvania American Water were filling their containers at a water buffalo.
Some people were there before daylight.
“We figure, let’s get there before everybody else,” said Rita Belback, who lives in Bethel Park, “…and how precious that water is, that’s the whole thing.” Bethel Park is one of six locations where water buffaloes were placed, to provide water for the customers affected by the Boil Water Advisory.
Several restaurants in the area were closed.
Al Taffel stopped by the water buffalo to get water for his four restaurants.
“Today, we have to figure out how to wash dishes and things like that,” Taffel told KDKA’s Lisa Washington, “but the important thing is keep hands washed and gloving up when handling the food.” In Jefferson Hills, Jim Ross needed water for his pets.
“This is for my dogs,” Ross said.
Pennsylvania American Water did their first test Monday night.
Until the advisory has been lifted, Pennsylvania American Water customers should boil their water for one minute and let it cool, before using it.
“I put two pots of water on the stove right away…a couple big pots and I put them in the refrigerator to cool them down,” Belback said.
