DEQ notifies city of required action on North Side water; DEQ reps to attend public meeting
July 21, 2014
On Monday, July 14, a representative from the Idaho Department of Environmental Quality conducted an unannounced visit to inspect the North Side water tank with Bonners Ferry City Water officials. That particular visit happened to occur just a couple of days before last week's City Council meeting where issues regarding the sanitation and safety of the North Side water was discussed.

City officials mentioned that DEQ visit in last week's City Council meeting, and reported the DEQ inspector again found "vermin" inside the tank, a problem the city has been battling for some time at the North Side water tank. That DEQ site visit was followed by a letter from the DEQ, directed to the City, along with a copy of a water analysis report.

Required Actions in the DEQ Letter
In the letter to the City of Bonners Ferry, a copy of which was obtained by NewsBF, the DEQ reported that water samples collected at the site during that visit show no coliform bacteria to be present, and also showed adequate levels of chlorine in the water to help prevent harmful bacterial contamination.

However, because of the ongoing issues with animal entry into the tank, the DEQ letter specified various required and recommended actions by the City.

"DEQ staff observed one rodent and two snakes within the reservoir during the July 14th inspection," said Suzanne Scheidt, Drinking Water Analyst with the Idaho Department of Environmental Quality. Ms. Scheidt, based out of the Coeur d'Alene DEQ office, is the DEQ representative who made the Bonners Ferry site visit.

Because of the ongoing issues with this tank, The Idaho DEQ is requiring implementation of the City's proposed plan, stating in the letter: "The City’s long term solution was to replace the existing wooden/aluminum reservoir roof with a concrete lid. This improvement is anticipated to bring the reservoir into compliance with current design standards for public drinking water systems. This project must be completed as expeditiously as possible."

Structural Questions
There has been some question as to whether the tank can structurally support a heavy concrete lid. Anna Moody, a Drinking Water Program Supervisor out of Coeur d'Alene for the DEQ, said "As part of their assessment, the City should consider whether the tank can structurally support a new concrete lid, or whether structural modifications/improvements will be required." The DEQ letter to the city specifies as an additional required follow-up action: "Engineered plans for the project must be stamped by a Professional Engineer who is licensed in the State of Idaho, and submitted to the Idaho Department of Environmental Quality (DEQ) for review and approval prior to initiating construction."

The DEQ states they are willing to help move the Bonners Ferry project through the evaluation process, their letter stating: "DEQ Engineering Staff will provide expedited plan review to ensure the project proceeds in a timely manner. Please provide a written timeline for completion of the North reservoir lid replacement project to DEQ by July 31, 2014."

Is the Water Safe?
Regarding the overall safety of the water, current testing, as noted above, do show adequate levels of water chlorination, and no coliform bacteria present. When asked if the tank has ever tested positive for harmful bacteria, Ms. Scheidt indicated that one sample collected from the Kootenai tribe back in 2009 tested positive for coliform bacteria, but negative for the particular E. coli bacteria considered to be harmful. A confirmation test done four days later in 2009 was negative for any bacteria. No other water samples from the tank have shown any coliform bacteria since 2009, according to Ms. Scheidt.

However, this testing refers to bacterial contamination only. The July 16 letter from the DEQ states that "Other microbial pathogens such as viruses are not easily cultured under laboratory conditions and thus are difficult to test for. Viruses also require additional contact time with chlorine in order to provide for effective inactivation (kill)." The DEQ letter points out that "The entry of vermin into the North reservoir presents an increased risk for introduction of viral contamination to the finished water supply. In order to protect water users from exposure to such microbial pathogens, additional improvements must be made to prevent vermin from entering the reservoir."

DEQ Also Making Recommendations
In addition to the items the DEQ is requiring the City to perform, they are also "recommending" several more. According to the DEQ July 16 letter:

"DEQ strongly recommends the City provide notification to water users served by the North reservoir in a timely manner. Recommended notification may include:

1. a summary of the current condition of the reservoir;

2. the City’s efforts to-date to remedy the situation;

3. potential increased risk to the finished water supply from vermin entry to the reservoir;

4. interim increased measures the City is implementing to minimize risk, and a timeline to provide a permanent correction through construction of a concrete lid; and,

5. a statement that water users may choose to consume bottled water or boil their water
prior to consumption to avoid all risk."

The DEQ administrators pointed out that the North Side water tank in question actually serves only a small part of the North Side Bonners Ferry population. A second water tank also serves the North Side, and this second tank is within requirements and has not had any of the problems of the tank in question.

'City Officials Proceeding Expeditiously'
Some residents have had concerns there has been inadequate attention paid to this problem by City water officials. Ms. Scheidt stated that "Since bringing this matter to the City’s attention on Monday July 14th, DEQ has found the City to be proceeding toward correction of the issue as expeditiously as possible."

Special City Council Meeting to Be Attended by DEQ
The City has arranged for a special City Council meeting tomorrow night to discuss this issue. Both of the DEQ officials cited in this article, both Ms. Moody, Drinking Water Program Supervisor, and Ms. Scheidt, Drinking Water Analyst, will be in attendance at that meeting. The public is invited to attend the meeting, to comment on the problem, and to hear reports and further information from the City Council and from City water officials.

The meeting is scheduled to be held at City Hall on Tuesday night, July 22, beginning at 7:00 p.m.
