MONTGOMERY COUNTY, Ohio (WDTN) – Maps showing contrasting boil advisory coverage is causing some confusion for residents in the county.
To figure out which advisory map you should use, you first need to know if you get your water through the Dayton Water Department, or through Montgomery County water services.
If you get your water through Montgomery County Water Services, click here for a map showing current boil advisory coverage or click here to see a list of addresses impacted.
If you are a Dayton Water Department customer, use this interactive map to see if the boil advisory applies to you: The following cities have their own water systems and were never affected by the boil advisory: Oakwood, Huber Heights, Vandalia, Englewood, Miamisburg, Union, and West Carrollton.
In a post to Twitter Thursday, Montgomery County reported Kettering, Centerville, Washington Township, Miami Township and Moraine were also clear of the water issues.
Officials with Montgomery County water services say that under the boil advisory, water is safe for consumption after customers have allowed their water lines to flush and/or run for a minimum of three minutes and then boil for at least one minute prior to consumption.
This should dissipate over the next few days.
They are expected to announce details at 10 a.m. on Friday.
City and County officials are working to create one map that will apply to all customers.
The City of Dayton has established three distribution sites at its recreation centers for customers to pick up Red-B-Gone laundry additive to protect laundry from discolored water.

When serial entrepreneur Samuel Ian Rosen topped his water bottle at an airport fill station and took a drink, it left a bad taste in his mouth.
Tap is a "software drink company" that maps out sources of clean, free water ー from street fountains to friendly bars, restaurants, and retailers.
The next step for Rosen is tackling plastic bottle waste.
"It’s kind of crazy to me that we leave our homes in the day and we purchase disposable, one-time, single-use plastic bottles because we are lazy.
The truth is, it is so easy to carry this bottle with us," Rosen told Cheddar Wednesday.
An enthusiast of Burning Man arts festival, which operates on the principle of "Leave No Trace," Rosen said the era of plastic bottles is coming to an end.
Rosen’s application, which he calls "the Google ($GOOGL) Maps for water," is designed to help make bottled water unnecessary.
He said it already boasts about 35,000 refill stations across more than 30 countries.
Rosen said the concept works because it costs bars and restaurants almost nothing to provide free water ー and more foot traffic may even expose businesses to new customers.
Restaurants, like Umami Burger and salad chain Sweetgreen "are opening their taps ー they have free water in stores for customers ー and they put a little sticker that says, ‘refill your bottle here,’ increasing the amount of foot traffic into their stores by giving away free water," he added.

Officially called perfluoroalkyl and polyfluoroalkyl substances, the group of chemicals had been used to manufacture everything from Teflon and Scotchgard water repellent to firefighting foam.
Early research suggests PFAS compounds may be linked to developmental and behavioral problems for infants and children, hormonal problems and even certain cancers.
A growing number of military veterans and others who believe they were exposed to PFAS are wondering if the chemicals triggered their health problems.
Two of the most prevalent types of PFAS are called PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate), but there are thousands of different compounds.
The EPA has set a lifetime health advisory for PFOA and PFOS at 70 parts per trillion, but federal research recently made public suggests exposure could be harmful at much lower levels.
At some Michigan sites, officials have detected PFAS levels below the EPA threshold.
In Parchment, known as the “Paper City” because of the shuttered paper mill that long operated there, Lt. Gov.
Brian Calley on Sunday declared a state of emergency after a test detected PFAS at more than 20-times the EPA health advisory level.
The list of contaminated sites is likely to grow as Michigan continues to test all public water systems and schools that tap well water for the chemicals — a process it kicked off in May.
PFAS may have been used or disposed of at as many as 11,300 fire stations, landfills, airports, military sites and other locations, according to a Michigan Department of Environmental Quality presentation first reported by the Detroit Free Press.

With so many water quality advisories and boil water notices in effect, in can get a little confusing.
“Is my water okay to drink,” is a comment question you’ll hear around the office or chatting with friends these days.
This makes it the perfect time for Interior Health (IH) to launch its new real-time, interactive water advisory map, which covers the entire IH region.
Not only can you find out whether your area has a water quality advisory or boil water notice, but you can also learn more about IH water suppliers, types of advisories and the reasons for them.
“Not everyone across IH has peace of mind that the water that comes out of their tap is safe.
With this map, individuals are provided accessible and up-to-date information on their water quality,” says Dr. Trevor Corneil, chief medical health officer at IH.
“If there’s an advisory on their system, they can make informed decisions related to possible health risks.
This level of understanding is also important, as local communities discuss future investments in their public and private water systems.” The map, which can be accessed by clicking this link, is a product of extensive stakeholder engagement and the June 2017 report, “Drinking Water in Interior Health.”

Despite the recent storm that pummeled the Sierra with snow and scattered rain in the valleys and along the coast, California remains unseasonably dry with 47 percent of the state experiencing at least "moderate drought" conditions, according to the federal government’s Drought Monitor.
The storm hailed by meteorologists as "the season’s biggest" gave the snowpack a little boost and ski slopes lots of fresh powder with many resorts reporting more than 7 feet of snow in the first week of March.
But seasonal totals remain well below normal and the new drought map released Thursday reveals no change in the unusual dry conditions that have mired the mountain range for several months.
Media: KCRA Null emphasized his point with the latest numbers from the Eight Station Index that measures the amount of precipitation (rainfall and water content in the snow) in the northern Sierra and is used to help determine the status of Northern California’s water supply.
The index stood at 19.92 inches before March 1 and the recent precipitation in the first week of March bumped it up to 24.06.
We only got more than 2 inches above normal.
What’s more, for the index to be at a normal reading for this time of year, the storm would have needed to boost the index up by 16 inches and Null says the amount of snow to reach that level would have been catastrophic.
State Climatologist Mike Anderson with the California Department of Water Resources says the map is mainly used "for rangeland ag support through the USDA and may not capture the nuance of different conditions present in California for different sectors."
The map from the week before the storm is nearly the same from the one after, with 91 percent of the state continuing to be abnormally dry in the latter map.
Most of Northern California, including the San Francisco Bay Area, is abnormally dry.

New maps, new website highlight drought effects on agriculture.
Maps highlighting the effects of drought on six agricultural commodities across the continental U.S. became available in late May on a website hosted by the National Drought Mitigation Center at the University of Nebraska-Lincoln.
The maps are a collaboration between the U.S. Department of Agriculture’s Office of the Chief Economist and the drought center.
The maps, produced at the drought center in cooperation with the USDA World Agriculture Outlook Board and OCE meteorologists, are based on the weekly U.S. Drought Monitor and show the locations and percentages of drought-affected areas that produce crops or livestock.
They are released Thursdays and can be found at agindrought.unl.edu.
In addition to the maps, the website offers data tables, time series graphs and animations.
In the near future, the partners will make available six field crop maps, one each for corn, cotton, soybeans, winter wheat, spring wheat and durum wheat.
The result highlights agricultural areas affected by any level of drought.
The U.S. Drought Monitor, produced weekly since 1999, is a collaborative effort among federal and academic partners, including the drought center, USDA and the National Oceanic and Atmospheric Administration.
The drought center also hosts the monitor: droughtmonitor.unl.edu/

New research from Environmental Working Group (EWG) and Northeastern University in Boston details PFC pollution in tap water supplies for 15 million Americans in 27 states and from more than four dozen industrial and military sources from Maine to California.
EWG and the Social Science Environmental Health Research Institute at Northeastern collaborated to produce an interactive map that combines federal drinking water data and information on all publicly documented cases of PFAS pollution from manufacturing plants, military air bases, civilian airports and fire training sites.
On the map, blue circles show public water systems where PFCs were detected in public drinking water systems – the larger the circle, the more people served by the system.
Red dots indicate a contamination site in Northeastern’s PFAS Contamination Site Tracker.
Drinking water contamination Despite widespread contamination and mounting evidence of health hazards, there are no federal regulations for PFOA and PFOS in drinking water.
EWG’s analysis of the results shows that the tests found PFOA and/or PFOS in 162 systems serving 15.1 million Americans.
Because the EPA only required reporting of detections at or above 20 ppt for PFOA and 40 ppt for PFOS, all of those water supplies had detections exceeding Grandjean and Clapp’s safe level of 1 ppt.
There is no ongoing national-level testing of PFCs in drinking water, and the EPA has said it could be 2019 or later before it decides whether to set a national drinking water standard for PFOA and PFOS.
The Site Tracker provides detailed information for 50 industrial or military contamination sites in 18 states and Guam, plus Australia, Canada and the Netherlands.
Groundwater at the base was found to have 580,000 ppt of PFOS.
