Pennsylvania American Water officials said Wednesday morning that the first set of water samples tested overnight came back with no signs of contamination.
However, the boil water advisory will remain in effect until the results from a second round of samples are tested and are clear of contaminants.
The water company had expected the advisory to remain until at least Wednesday.
Cloudy tap water prompted the boil water advisory on Monday.
The private utility said the cause of the turbidity 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 first samples were taken Monday night, the second round of samples Tuesday night.
Turbidity readings and total coliform tests are done in-house, and Pennsylvania American’s lab is certified by DEP.
But it may interfere with disinfection and allow for growth of viruses, bacteria, and parasites, the water company acknowledged on its website 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.

Ground shifting caused by a sudden drop in temperature over the weekend triggered nine water main breaks across Saskatoon between Monday afternoon and Tuesday morning.
Lack of running water forced cancellation of classes at Caswell School, which will also remain closed today.
City Hospital — which receives water from three water main lines, including one that broke Monday night — issued a precautionary boil water advisory because of a drop in its water pressure.
City staff delivered door hangers to people living in affected buildings, including nine downtown apartment complexes, informing them of the breaks.
As of Tuesday morning, water trailers were available to provide drinking water to people who would be without water for more than 24 hours, and city-owned leisure centres opened their changing facilities so people in affected areas could shower for free if they presented identification confirming their addresses.
Munro said it costs about $12,000 to fix each water main.
Traffic on 25th Street was snarled on Tuesday morning and road restrictions may last until Thursday morning.
Munro said this week marked the first time the 47-year old pipe has failed.
Although Saskatoon frequently experiences significant temperature swings, there’s little the city could have done to prevent this week’s mass water main breaks, Munro said.
It would be very, very costly, making the water difficult for people to afford.

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.

OTTAWA, Kan. — The Kansas Department of Health and Environment put the city of Ottawa, Kansas, under a water boil advisory Tuesday due to potential contamination.
The department said the advisory has been issued because compressed air entered the distribution system during maintenance on the irrigation system at Ottawa High School.
The compressed air puts the city’s water system at risk of being contaminated.
The department said the advisory will remain in place until the risky conditions are resolved.
According to the department, residents should: Boil water for one minute prior to drinking and food preparation or use bottled water.
Dispose of ice cubes and don’t use ice from a household automatic ice-maker.
Disinfect dishes and other food contact surfaces by immersion for at least one minute in clean tap water that contains one teaspoon of unscented household bleach per gallon of water.
Water used for bathing does not generally need to be boiled.
Persons with cuts or severe rashes may wish to consult their physicians.
If your tap water appears dirty, flush the water lines by letting the water run until it clears.

A boil water advisory was put into effect Nov. 6 for at least 100,000 customers in Allegheny and Washington counties, including people living in several South Hills communities.
The advisory announced by Pennsylvania American Water affected customers in more than 50 communities, including South Fayette, Upper St. Clair, Bethel Park, South Park, North Fayette, Peters Township, Canonsburg and Cecil.
Township.
Mt.
Potable water tanks for those residents were set up at the Bethel Park Community Center, South Fayette Township Library, Upper St Clair Community Recreation Center and Peters Township Municipal Building.
People are asked to bring their own containers to fill with water.
The company said water samples showed turbidity levels, or cloudiness, above normal standards.
The high turbidity level indicated a possibility that the water might contain disease-causing organisms.
Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes and preparing food.

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.

Residents of Duncannon should continue to boil water all weekend DUNCANNON, Pa. — Officials in Duncannon, Perry County have extended the boil water advisory through the weekend.
After consulting with our engineer and our water system operator, the decision has been made to keep the Boil Water Advisory in effect through the weekend.
It had been hoped that the advisory could be lifted late in the day on Sunday, however one final part of the project must be completed on Monday.
Original plans called for that are to be isolated from the system, so it would not cause any loss of pressure.
However, given the problems experienced all week in trying to isolate areas for shutdowns and the unpredictable condition of many of the valves in our system, the professionals advise we cannot count on that approach working.
Water will be turned on throughout the weekend and it is hoped any outage on Monday will be brief, and isolated.
However, if you are in an area under the Boil Water Advisory, please continue to boil water before consuming it.
We will issue another Code Red alert when the Boil Water Advisory is lifted.
We will also post updates on the Borough’s web site and Facebook page.
