August 20, 2012

The Town of Jackson Board met on Saturday, August 18, 2012, to review the information received related to the DNR "General Permit to Discharge Under the Wisconsin Pollutant Discharge Elimination System," specifically the discharge of wastewater from West Shore Pipe Line's remedial operations at the site in the Town of Jackson. The Town Board voted in support of the DNR permit as presented to the Town, but stipulated that the following items be added to the requirements.

  1. There will be three consecutive tests done to ensure the water being discharged has been "cleaned" prior to discharging onto the ground.
  2. The Mill Road culvert that moves the water between the two drainage ditches being used will be lined with a plastic liner to prevent/minimize damage from continuous flow or standing water.
  3. West Shore will promptly address any future town right of way issues directly related to the project, such as erosion, ditch flow or culvert deterioration, to Town specifications.

The permit was issued on Sunday, August 19, so that the work of laying the discharge pipe can begin in the Town right-of-way.

The DNR now has permission to pump and treat groundwater from the Jackson spill site and discharge the treated water (via the approved WPDES permit).

For more information, please contact Eric Nitschke, Southeast Regional Director, 414-263-8570.

August 13, 2012

On Friday, August 10, the DNR received laboratory results showing detection of Benzene over state health standards in two wells that previously had no impacts. These two properties are located to the east of the Flush Only Advisory Area. The department has issued Flush-only Drinking Water Health Advisories for each property and notifed both homeowners about the contamination. Both houses have Point-of-Entry Water Treatment (POET) systems installed.

In addition, there will be fencing installed for construction purposes at two other properties affected by the contamination. Under the state administrative code NR 700, Wis. Adm. Code, fencing is often installed at cleanup sites to protect public safety.

Drinking water advisory

Drinking water advisory issued as a precaution

The DNR, working with state and local health departments, has issued an Areawide Drinking Water and Flush Only advisory as a precaution because of the contamination of some wells. All private well owners in the advisory area should use bottled water or water from a known safe source for drinking, cooking and food preparation. Residents in a smaller "Flush Only" area should limit well water use only to flushing their toilets. NOTICE: FLUSH ONLY ADVISORY LIFTED AS OF AUG. 30, 2012

If you aren't sure if you're part of the advisory, please view the map on page two of the DNR's August 3, 2012 advisory [PDF].

Read more information about the advisory [PDF] from the Wisconsin Department of Health Services.

Information for homeowners

  • Private well owners in this area should use bottled water, or water from a known safe source for drinking, cooking and food preparation.
  • The boundaries of this areawide advisory were selected to be precautionary. Not all the homes in this area have wells that have been impacted by the spill. Areas within this boundary that may be served by water from the village of Jackson municipal system are not subject to this advisory.
  • NOTICE: FLUSH ONLY ADVISORY LIFTED AS OF AUG. 30, 2012 Within this Areawide Drinking Water Advisory, the Department of Natural Resources also is issuing a Flush Only Advisory for the following area:
    • subdivision along Wildflower Lane to the north of Mill Road; and,
    • subdivision along Mockingbird and Hummingbird Drives south of Western Avenue, and generally bounded between these two subdivisions in an east-west direction.
    Homes in this area should use their water only for flushing toilets. This means no skin contact, no laundry, no bathing and no lawn or garden watering. People in the Flush Only Advisory area will be contacted by West Shore Pipeline Company or the Department of Natural Resources.
  • Water sample results are reviewed daily by DNR staff to determine if the advisory boundaries need to be adjusted. Please note: Well data will change as more information is collected.

DNR response

After the spill was detected, DNR staff responded and worked to contain the spill and address the contaminated wells. Agency drinking and groundwater staff developed a list of wells to be sampled. On July 31, 2012, the DNR issued an Areawide Drinking Water and Flush Only Advisory. The area included in this Drinking Water Advisory is bounded by the following roads.

  • Western Boundary – Jackson Road
  • South Boundary – Spring Valley Road
  • East Boundary – Center Road
  • North Boundary – Sherman Road

On August 3, 2012, the department sent out an advisory [PDF] to 256 residents with information about the progress of the investigation.

Who to contact

People in the Areawide Drinking Water Advisory should contact the following individuals to make arrangements for bottled water.

  • Sharon Guillory, West Shore Pipeline Company, 832-325-1617
  • Scott Ferguson, DNR at 414-263-8685
  • Zoe McManama, DNR at 262-496-5180

Well testing/cleanup

Well testing and cleanup

West Shore Pipeline Company is responsible for sampling private wells. As of July 15, 2013, a total of 298 water supply wells at 286 residences have been sampled. More than 13,000 individual water samples have been collected by West Shore Pipeline’s consultant and have been analyzed by a state certified laboratory.

Benzene has been detected in 44 wells, and the DNR has issued 37 private well-specific health advisory letters for the wells having benzene levels above health standards. In the last sampling event, 24 private wells had a detection of petroleum compounds above a health standard, and two wells had a detection of petroleum compounds below the health standard. In total, 39 private wells have had detects of petroleum impacts from the spill.

West Shore Pipeline is providing bottled water to all of the affected homes and has also installed point of entry treatment systems for non-drinking purposes at homes within the Drinking Water Advisory Area. As of July 1, 2013, 80 point of entry water systems have been installed - with additional systems available should conditions warrant - and post-installation sampling is ongoing. Groundwater monitoring wells have also been installed around the perimeter of the pipeline spill.

Next steps

The DNR continues to work with officials from the town of Jackson, village of Jackson and West Shore Pipeline to implement a long-term water supply solution for the impacted homes.
