PCEs with your Pie, Anyone? Toxic Plume Under Goodman Center Still Ignored…

PCEs with your Pie, Anyone? Toxic Plume Under Goodman Center Still Ignored…

A couple weeks ago, I had lunch with a friend in the Ironworks Café at the Goodman Community Center. The food was delicious and the servers were helpful and friendly.  Pre-school age children were laughing and playing in the playground. Teenage kids were taking plants from the raised-bed gardens just outside the café to the compost pile. We agreed that Goodman’s gardening and food service programs for teens, and other programs for children, are impressive and commendable.

But while munching on my sandwich, I remembered that the highest levels of PCE found on the Goodman property before redevelopment (in 2001) were in soils just a few feet outside my window, under the outdoor cafe. PCE over the enforcement standard level was also found in the groundwater below where the outdoor café is now. It’s not clear how deep this contamination was at the time.

In April 2013, Madison-Kipp Corp. consultants released a map of a huge plume of much higher levels of PCE and other volatile organic compound (VOC) contamination beneath the Goodman property. Given that the highest levels of groundwater contamination at Madison-Kipp are at the northern part of the property, just across the bike path from the center (a few feet from the raised bed gardens), this is not surprising.

The top layers of contaminated soils at Goodman were removed and replaced before the center was opened, but the contaminated groundwater is still there. What levels of PCE and other VOCs are beneath the center now? How far below? Is the plume releasing toxic vapors into the Goodman Center? Nobody knows.

And apparently, nobody wants to know. This month the DNR released documents showing that the agency is finally asking Kipp to sink a shallow well on the Goodman property. But why will this well be located way out in the parking lot area? Toxic vapors released from any shallow groundwater contamination there will mostly dissipate in outdoor air. Whether contamination is or isn’t found there, this will not tell us much about exposures to people inside the Goodman Center. If there are PCEs and other toxic VOCs in shallow groundwater beneath the center, vapors released from this water will likely concentrate beneath the center—and then seep up into the building. Testing way out in the parking lot will tell us little to nothing about exposures to people in the center.

Yet again, we ask: Why are potential toxic exposures to the most vulnerable people—children and seniors in the Goodman Center—being ignored? Why have our questions about these potential exposures been repeatedly ignored or dismissed (and at times even ridiculed) by public health officials and Goodman leaders? Since the significant and widespread PCE and PCB contamination at Kipp was uncovered in 2011-2012, to our knowledge not even a single test has been done at Goodman to see if children there are exposed to Kipp’s contaminants in soil, groundwater, and/or air. Why not?

Perhaps neither Madison-Kipp nor Goodman leaders want to open up this politically messy can of worms—especially since they have been in bed together for years. Madison-Kipp has supported Goodman in a variety of ways, financial and otherwise, since the center’s inception. A year before the center opened, in a May 2007 letter to the Madison Planning Commission, CEO Reed Coleman bragged that “Madison-Kipp is a proud supporter of the new Goodman Atwood community center. What an asset it will be to the entire east side. Madison-Kipp is committed to helping with the success of the new center and have lent our support in numerous ways…” (Ironically, he then goes on to offer parking in the Kipp lot, which we now know was coated in PCBs for years, for Goodman Center users).

While things seem to have been cozy historically between Madison-Kipp and Goodman, opening up the can of worms related to Kipp’s toxic contamination plume under Goodman could turn very ugly, with former bedfellows quickly becoming enemies. Though Goodman closure documents explicitly state that Kipp is the source of the PCEs in the groundwater under the Goodman property, if this issue was opened up again, Kipp would likely blame past industrial activities on the Goodman property (e.g., Kupfer Ironworks). In a March 2012 email to the DNR and other public officials, Kipp attorney David Crass resisted DNR’s request that soil vapor probes be placed on the bike path north of the Kipp property,[1] noting that “…historic PCE use has been documented at the Goodman Center property, which will lead to questions regarding origins of any results and will infect any future decisionmaking regarding the results.”

Hmmm. So maybe it’s to both Goodman’s and Madison-Kipp’s benefit to stay mum and resist testing, and deny any public health risks at Goodman—regardless of the source of the pollution—rather than face the uncomfortable prospect of intense political, legal, and financial battles with former bedfellows?  In a twisted way, perhaps Kipp and Goodman are protecting each other?

What about government officials? Why are they so adamantly declaring that there are no exposures whatsoever in the center, though there haven’t been any tests? It seems they are either woefully unaware of the current scientific research and EPA guidances on PCE vapor intrusion (which indicate that vapor intrusion should be investigated in the Goodman building), or they are totally ignoring them. Of course, they approved the re-development of the Goodman Center in 2008 apparently without considering vapor intrusion, even though extremely high levels of PCE and other VOCs had already been well documented on the northern part of the Kipp property (just feet away from the Goodman building) beginning in 1994. If tests now were to show that vapors from the plume under Goodman are leaking into the center (and/or that children there are exposed to other toxic contamination from Kipp), blame for the lack of oversight that led to these exposures would be directed at them. Maybe not testing at all is way to avoid this uncomfortable situation?

So if our suspicions are correct, Madison-Kipp, Goodman leaders, and government officials alike are, ironically, protecting each other (intentionally or not) by putting their concerns about politics, money, and reputations above assessing risks to children and seniors, who apparently don’t matter in their political games. How unethical is this?

Note to readers: We would love for our speculations above to be wrong. If anyone out there wants to disagree—or better yet, send information disproving anything said above—please do so! Email info@mejo.us



[1] Vapor probes were eventually placed along the south edge of the bike path and results from 3/30/12 and 10/26/12 showed concerning levels of PCE and several of its breakdown products at the probe right across from the circle gathering area at Goodman. If these levels were under a building, they would likely be a problem as far as vapor intrusion inside the center. But it seems nobody will test inside—or even anywhere near—the center.

Oops!!! Maybe a Raingarden for Kipp’s Toxic Runoff Wasn’t a Good Idea After All?

Oops!!! Maybe a Raingarden for Kipp’s Toxic Runoff  Wasn’t a Good Idea After All?

 

 Children Creating Kipp Raingarden in 2006–Mucking Around in Kipp’s PCBs! Original Photo Caption from the 2006 Rock River Newsletter: Whitehorse Middle School science students seemed to enjoy rolling up their shirtsleeves and  pants legs to plant more than 2,000 of the 3,200 plants at the Friends of Starkweather Creek rain garden at Kipp and the bike path in Madison. A casualty of the muck: one pair of a student’s flip-flops and one of Susan Priebe’s pink “Crocs.” For photos and more information, see: http://www.rockrivercoalition.org/publications/newsletters/RRCfall2006c.pdf

 

In an October 9, 2013 letter, Wisconsin DNR and City of Madison asked Madison Kipp Corporation to remove contaminated soil from the raingarden built next to MKC on city property in 2006 by Whitehorse Middle School students and teachers (in the photo above) along with many other volunteers. Soil tests done by Kipp consultants in the raingarden in June 2012 showed polychlorinated biphenyl (PCB) levels above the residential and industrial “direct contact” residual contaminant levels (RCLs); in other words, direct physical contact with this soil should be avoided.[1]

We commend the DNR and City for finally asking Kipp to excavate this contaminated soil. But why did they wait over a year after Kipp consultants tested soils in the garden area share this data with the public and ask Kipp to excavate? Also, recently posted documents don’t tell the whole story. Kipp consultant documents posted by the DNR on Nov. 1 selectively highlight results from only one soil boring, not reporting results from borings just a few feet away showing much higher levels of PCBs, polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). For instance, one shallow boring on the edge of the raingarden, not reported in recent documents, had total detected PCB levels of 45 ppm— significantly higher than the residential RCL (.222 ppm) and the industrial RCL (.744 ppm). The levels reported from just one boring were much lower (.82 and 2.5 ppm), though still higher than the RCLs.

Documents also don’t mention that all soil tests in the raingarden area showed that tetrachloroethyene (PCE), trichloroethylene (TCE), 1, 1,-dichloroethene, carbon tetrachloride and vinyl chloride were much higher than the “soil to groundwater pathway” residual contaminant levels (also called RCLs). In other words, these chemicals in the soils pose risks to groundwater, which is very shallow in the raingarden area—only 10 or less feet below the surface. This is more than a little ironic, given that the purpose of the raingarden is to encourage contaminants to filter downward.[2]

Further, in all raingarden soil samples, arsenic levels were much higher than residential, industrial, and groundwater RCLs. Kipp consultant documents dismiss this, noting that “The presence of arsenic in the rain garden appears to represent naturally occurring background conditions.” Whether or not all of this arsenic is “naturally occurring,” arsenic is still very toxic to humans and in many places is becoming a significant problem in groundwater. Given this, why are these levels being dismissed? Why is there so much arsenic, natural or not (likely both) everywhere in surface soils? Metal smelting (which is what Kipp does) is known to produce arsenic, but that couldn’t possibly have added any arsenic to the soils next to the plant, right? Why isn’t anyone even asking this question?

Sadly, regardless of these findings, public health officials are dismissing or ignoring obvious human exposures to these soils in disingenuous (if not absurd) ways. When we raised questions about exposures to children who created this raingarden, in an October 2012 article, public health officials ridiculed us as “alarmist” and “wrong,” even though by that point raingarden soil tests (not shared publicly yet) had already verified that the area was quite contaminated. More recently, in a Nov. 5 Wisconsin State Journal article, John Hausbeck from the Madison Dane County Public Health Department assured us that “Those using the bike path generally would not be exposed to what’s going on in the ditch” (no duh! as if that is what people are concerned about…). But he said nothing at all about exposures to the children who created the raingarden—and people who have maintained the garden since 2006.

Were the children and adults working in close contact with this soil aware of the contamination, so they could take precautions (gloves, boots, etc) as any workers who will now excavate the soil are expected to?[3] Based on the photo above, no. Would parents of the children who helped create the garden let them work there had they known about the contamination? We doubt it.

This sad situation raises many questions about why city, county, and state government officials allowed this raingarden there in the first place—and why the neighborhood so enthusiastically supported it.[4]

The raingarden project was funded by a Dane County Water Quality Initiative Grant and coordinated by the Rock River Coalition, and was lauded by the neighborhood, government agencies, and Mayor Cieslewicz. Project partners included SASYNA, City of Madison, Madison Kipp Corporation, Madison Gas and Electric Co., AtwoodCommunity Center, Glass Nickel Pizza and Whitehorse Middle School. It was created explicitly to address runoff from MKC and to protect Starkweather Creek. According to the Rock River Newsletter (link above) about the project, Whitehorse students and volunteers “helped plant, apply weed barrier, and mulch. The rain garden will help capture stormwater runoff coming from the Kipp parking lot…and protect a fen-like area around Starkweather Creek (emphasis added).

We think raingardens are great, and we commend efforts to protect Starkweather Creek from further pollution. By 2006 the creek had already been polluted for over 100 years by Kipp, Rayovac (now gone), numerous other industries, the airport and widespread non-point urban runoff (in the 1990s, a huge quantity of PCB and metal-contaminated sediment was dredged from the creek). But was a raingarden the appropriate (or ethical) way to deal with highly contaminated runoff from Madison Kipp (or any heavy industry), given what was known at that point? By 2006, Kipp and DNR documents dating back to the 1990s showed that contaminated runoff from the most toxic hotspots at the Kipp factory went for decades into a drainage ditch that emptied into the rain garden area. Kipp officials, of course, also knew that they had used PCBs for decades on the parking lot next to the raingarden area—the same parking lot the raingarden was supposed to capture runoff from.[5]

Why would anyone think a raingarden is a good way to deal with toxic runoff from MKC? Even more troublingly, why would anyone think that having children build such a garden in that location is OK? At the least, why didn’t agencies involved have the soil tested before the raingarden was created?[6]

Unfortunately, this situation reflects the ongoing denial among government agency officials, including the ones responsible for protecting public health, that there could be any actual exposures to toxins among people around Kipp, and especially to the most vulnerable—children. While Kipp consultants continue to measure high levels of very toxic contaminants on and around the Kipp property, no matter what the results, officials deny that anyone is (or was ever) exposed, despite abundant and obvious evidence to the contrary. They marginalize and discount anyone who even raises questions about possible exposures as “alarmist.” Why?


[1] When the garden was built, 2-4 feet of soil were excavated and backfilled with “new” soil (consisting of sand, compost, and topsoil). It is highly likely that the original soil excavated was much more contaminated than the backfill, given that this area was the recipient of decades of toxic runoff from the Kipp property. However, the 2012 tests suggest that the fill may have been contaminated as well and/or that Kipp runoff since 2006 contaminated it (or both). Where did the original soil go? Where did the fill soil com from?

[2] Ironically, the consultant for the city (CGC, Inc.) that did the original analysis of this site concluded that “Based on the relatively thick layer of low permeability clay encountered in the borings, this site does not appear suitable to infiltrate significant quantities of rainwater.”

[3] Kipp’s consultant documents state that “If any soil is excavated below grade…personnel shall wear appropriate personal protective equipment to limit exposure to the contaminants…” (August 2013, ARCADIS Materials Handling Plan).

[4] MEJO leaders questioned garden proponents about the safety, efficacy, and ethics of this garden in 2005-6, but were ignored.

[5] The soil removed to create the raingarden was likely much more contaminated than the soil that replaced it. DNR claimed not to have known about the use of PCBs on the parking lot till 2012; this may be true, but they would have at least known about the possibility that PCBs were used on the parking lot had they read documents Kipp consultants submitted to them. Regardless, the agency certainly knew about all the other toxic contaminants found throughout the Kipp property and the drainage ditch that for decades emptied into the raingarden area. MKC’s enthusiastic support for the raingarden project raises even more troubling questions. Did MKC, perhaps, support the raingarden project in part because they wanted the soil there to be excavated to remove highly contaminated soil they knew would be there?

[6] The consultants who did the soil boring for this project (CGC, Inc., subcontracted to Kitson Environmental Services) noted that they had not screened for environmental contaminants because they had not been asked to by the City. Their disclaimer section read: “Unanticipated environmental problems have led to numerous project failures (emphasis in original). If you have not yet obtained your own geoenvironmental information, ask your geotechnical consultant for risk management guidance. Do not rely on an environmental report prepared for someone else.” But apparently the City never did any soil contaminant testing or asked for any advice on “risk management” from their consultant.
