Airway Heights water safe to drink, officials say.
Airway Heights officials said Thursday that the city’s water supply is now safe to drink.
Since the discovery of the high levels of contamination, the city began to flush its pipes with Spokane water.
But it took three weeks for enough of Spokane’s water to clean out the system to levels considered safe to drink.
Any water restriction must be approved by the City Council and would likely mean establishing an odd-even day watering schedule.
Although Spokane can pull as much water as needed from the aquifer, Anderson said how much Airway Heights can receive is limited by the connections to Spokane’s water system.
Or, they could tap into a Fairchild Air Force Base water line that runs through the city of Airway Heights.
“And I don’t blame them.” Wolffy’s Hamburgers owner Justin Davis also said his business was down significantly.
“The biggest thing is the customers are scared,” he said.
At first the city provided restaurants with potable water, Anderson said.

Unwell water history.
Since 2014, 22 public drinking water wells and more than 200 private wells in Bucks and Montgomery counties have been shut down due to contamination by unregulated chemicals perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), affecting the drinking water of more than 100,000 people.
The bulk of the contamination is occurring near a trio of former and current military bases in Horsham, Warminster and Warrington, and is suspected to have originated in firefighting foams used on those bases as far back as the early 1970s.
Contamination from unknown sources has closed wells in Doylestown, Chalfont, East Rockhill and other communities.
This news organization has been investigating and writing extensively on the topic, telling the stories of local people who believe they’ve been sickened by the chemicals, speaking with health experts on potential effects of exposure, and examining actions taken by local, state and federal agencies.

All schoolchildren deserve clean, safe drinking water: Connie Leyva and Eloise Gomez Reyes.
If no one tested the water, those pipes could remain in use for decades — slowly releasing dangerous lead particles into our drinking water.
Lead in drinking water can be dangerous for a person’s health, especially for young children with growing bodies and brains that are still developing.
This year, the San Ysidro School District found lead contamination in several drinking fountains at three of its local schools.
These numbers may seem small, but they represent dangerous lead levels in thousands of schoolchildren.
School districts are now able to receive free testing from their local water agency to check for lead and copper in their water.
Advertisement Earlier this year, we authored SB210 to ensure that K-12 students across California have access to clean drinking water at school.
Children spend a large part of their weekdays at school, and we are proud to stand alongside California families to make sure that our local schools are using the resources available to them to check for and fix the lead contamination that may be harming their children.
We urge you to contact your local schools and school districts where your kids attend to make sure that — if they have not already done so — they request free testing from the local water agency.
State Sen. Connie M. Leyva, D-Chino, represents the 20th Senate District.

Stuart replaced wells after EPA found too much PFOS and PFOA in drinking water.
In 2016, when the EPA recognized the chemicals’ dangers and lowered acceptable PFOS levels by 65 percent, the city closed and later replaced the wells that were contaminating the water supply to all customers, city spokesman Ben Hogarth said.
Cleaning the water Stuart’s levels meet today’s EPA standards, as they did before 2016, but they’re still higher what many experts consider safe.
Heightened exposure can cause cancer, liver damage, low birth weight and a weakened immune system, according to the EPA.
The only safe level is 1 part per trillion, said Bill Walker, an Environmental Working Group senior scientist.
That’s analogous to one square inch in 250 square miles.
The city also has allocated $600,000 in the 2017-18 proposed budget for additional water treatment that would remove these chemicals, Peters said.
Some experts caution individuals against relying on such filters, however.
"We think this is an issue that needs to be addressed on a community level, and it shouldn’t be down to the individual homeowner to remove these types of chemicals," said Andrews, the Environmental Working Group senior scientist.
Their health effects are unknown, and they’re not as easy to remove from water as PFOS and PFOA, said Phil Brown, a Northeastern University professor who co-authored a study with the Environmental Working Group on PFOS and PFOA levels in drinking water throughout the U.S. More studies Stuart’s previously high levels were cited in that study, released Thursday.

Fire fighting foam contamination sites clustered along Delaware River.
A national mapping project detailing tap water contaminated with toxic chemicals used in fire fighting foams and nonstick frying pans shows a large number of those public water systems along the Delaware River in Pennsylvania, New Jersey and Delaware.
The chemicals, commonly referred to as PFC’s, (and include PFOA and PFOS), are used by manufacturers in making non-stick pans, waterproof clothing, take out food packaging, and fire-fighting foams.The compound is no longer manufactured in the U.S., but increasing numbers of drinking water sources have been found to contain levels that exceed EPA’s maximum contaminant levels.
The report, entitled “Mapping a Contamination Crisis,” reveals 15 million people are exposed to PFC’s through their drinking water resulting from use of the chemical at manufacturing sites and military bases across the country.
David Andrews, a senior scientist with the Environmental Working Group, says the bulk of the data came from the EPA, which required drinking water facilities that served more than 10,000 people to test for PFC’s between 2013 and 2016 and report findings to the federal government of levels above 20 parts per trillion for PFOA and 40 ppt for PFOS.
Andrews says they found 162 systems serving 15.1 million people had high PFC levels.
Seventeen of those tap water sources were located in Southeastern Pennsylvania, New Jersey and Delaware along the Delaware River.
New Jersey officials have recommended lowering the maximum levels from 70 ppt to 14 ppt.
Some have suggested it should be as low as 1 ppt.
The Delaware Riverkeeper Network recently petitioned Pennsylvania officials to set a lower level than the federal standard based on new peer-reviewed research into the health impacts.

New research from 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.
[3] Drinking water contamination Despite widespread contamination and mounting evidence of health hazards, there are no federal regulations for PFOA and PFOS in drinking water.
Under the EPA’s Unmonitored Contaminant Monitoring Rule, or UCMR, from 2013 to 2016 all U.S. public water systems serving 10,000 or more customers tested their supplies for PFOA, PFOS, and four other PFCs.
[†] 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.​ Several large metro areas had detections in only a small number of samples.
[7] 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.
Of the 47 locations where the source of the contamination is known or suspected, 21 sources are military bases, 20 are industrial facilities and seven are from civilian firefighting sites.

Study results released on Kewaunee County water contamination.
Luxemburg, Wis. (WBAY)- For months we’ve been hearing stories about brown water in Kewaunee County.
A study conducted by three different agencies to sought to determine that, and at a public meeting in Luxemburg Wednesday night a big crowd gathered to find out, what’s causing it.
That contamination level is much higher than in other counties within the state.
Some of it, stems from shallow soils– which are used for farming and bed rock beneath that.
Groundwater Task Force said, "There’s not enough soil to filtrate all of the viruses and contaminates.
We also have some likely contamination coming from septic systems."
The county hopes to use these study results as a way to promote changes both at the local level and with state legislators.
Davina Bonness of the Kewaunee Co. Land & Water Conservation Department said, "So what we’re doing in the county is we’ve dropped a couple of ordinances trying to get some low pressure drip irrigation systems, trying to spread that window of manure irrigation over the entire growing season, and hopefully that will help with some of the manure contaminants."
Also, inspections of septic systems are now a bigger priority.

VANPORT TWP. — Multimedia conglomerate CBS is refusing to pay for research conducted by the state Department of Environmental Protection that will determine the extent of potential groundwater contamination in Vanport Township and has called the agency’s response “unreasonable and unnecessary.” Officials continue to maintain that the 10,000 customers who get their water from the Vanport Township Municipal Authority have no reason to fear their water is contaminated.

The department has initiated an extensive and expensive response in the area behind the Brighton Hot Dog Shoppe and the McDonald’s on Third Street. The response includes eight different action items, including thorough testing of water, soil and pump treatment systems to determine the threat to Vanport’s drinking water.

Well water still contaminated 7 months after Smiths Falls fire.
It’s been seven months since a fire outside Smiths Falls, Ont., left several homes with contaminated wells, and it could still be months before residents are allowed to use their water again.
"We thought they’d be hooking wells back up by now."
Toxic runoff from the charred debris, along with firefighting foam, got into the groundwater and residents reported foam and a chemical smell coming from their taps almost immediately after the fire.
Tina and David Stevens initially purchased a house on Highway 43 as an income property.
The wells and groundwater monitoring networks were tested last month.
The results are being reviewed before they are released to homeowners, according to the ministry.
‘Still some trace levels’ "The preliminary review is that we’re seeing continued trends downward of the contaminants of concern, but we’re taking a close look," said Steve Burns, a district manager for the ministry.
But residents said they are still out of pocket for some expenses and they’re concerned about the value of their properties.
"Can you get a mortgage on a property that doesn’t have potable water?
