Why concrete washout is harmful to the environment

Most contractors know that concrete slurry or washout can cause a fish kill, if it reaches a lake or stream.  That's because the fluids are highly alkaline--as corrosive as draino.  And aquatic organisms are extremely sensitive to changes in Ph (alkalilnity).  

For that reason, it's illegal in Madison to discharge washout to the gutter.  Violations are enforced by Public Health and referred routinely for prosecution.  Contractor Report documents washout spills with photos and reports them immediately to Public Health.

However, dumping concrete waste or slurry to the soil is legal.  But that doesn't make it a good practice or good public relations.  There's increasing evidence, reported below, that concrete waste in the soil has the potential to harm the environment and degrade our drinking water.

Life far underground

In the last 20 years, our knowledge of bacteria has undergone a revolution.  We now know that bacteria can live inside solid rock.  Bacteria live and reproduce high in the clouds--where they help form rain as water condenses upon their bodies.

Edgewater construction causes muddy plume in Lake Mendota

In the evening of May 27, 2014, shortly after the heaviest downpour ended, a boater* observed a muddy plume extending 100 feet out from the Edgewater Hotel construction site into Lake Mendota.

The observer noticed an eroded rill on the east side of the construction site, but did not actually observe the runoff leaving the site.  However, the location of the muddy plume strongly suggests that Findorff Construction, the main contractor at the site, was responsible.

Construction site threatens Lake Wingra

The construction site for apartments, at the corner of Arbor Dr. and Knickerbocker St., has been consistently poor in its erosion control. It's just a stones throw from Lake Wingra.

On Oct. 26...

  • There was concrete slurry leaking directly into a stormwater inlet.
  • The street had not been swept--fine dust was blowing about.
  • Stormwater inlets were dirty and not maintained.
  • One stormwater inlet next to the construction entrance had no visible protection.
  • Construction entrances were not adequate.

19 % of phosphorus from construction--source of the data

"Studies show that 19% of the phosphorus in our lakes comes from construction site erosion."

We've been asked for the source of this data...

The figures below are for Lake Mendota.

"Inventory and modeling produced estimates of sediment and phosphorus loadings to the lake (see Table 1). Several surprising findings emerged from the planning work. The first was that although less than 1 percent of the land area was undergoing development, models suggested that portion of land accounted for almost one quarter of the sediment loading and one fifth of the phosphorus loading to the lake (WDNR 2000)."

The importance of good tracking pads

Below: Trackout from just 1 vehicle, 1 trip, at a construction site.

Muddy tracks aren't a question of appearance--often they are nearly invisible.

Muddy tracks you can see are just the tip of the iceberg.

If you can see any tracks at all, then you can bet there are tons of mud washing into our lakes from this construction site (see calculations below).  

When contractors sweep at all, it's usually just around the construction entrance.  But that's not enough--because the bulk of the mud is dropped beyond the sweeping distance.

Upper left: Tracks by north entrance about noon. Click on photo to enlarge.

Upper right: Same area at quitting time.  Different tracks indicate there was an earlier sweeping, but not late enough to remove all the tracks before another rainstorm after work.

Bottom left: Faint tracks & small clods on Gately Ter, 4 blocks away.

Nine tons of sediment from Sequoia Commons construction

The calculations below are guesses, needing much refinement.  The purpose is simply to show how mud on tires can really add up.

Each tire (right) easily carries 10 pounds of mud

  • Assume construction takes 1 year, 5 days a week for 52 weeks.  Assume that only half of those days have mud on-site (rain is less frequent--but mud persists for a while).  This gives 130 days a year when mud might be tracked off-site.
  • Assume each day, on average, 10 visits of vehicles with large wheels, 6 wheels per vehicle (concrete tucks have more tires).  Assume each wheel can track 2 lbs of mud off-site.  Total, 12 lbs mud per visit or 120 lbs per day.
  • Assume each day 20 visits by smaller vehicles like pickup trucks, with 4 wheels.  Each vehicle tracks a total of 1 lb mud off site.  Total, 20 lbs per day.
The total mud tracked per day is 140 lbs X 130 days, for a grand total of over 18,000 lbs/year, or 9 tons.

How can so much mud be tracked out, when you can barely see the tracks?  Simple--it's miles before all the mud drops off the tires.  It's spread so thinly across the roads you can barely see it.  But it still winds up in the lake.  After a rain storm in June, I followed one muddy track for six miles.

Yahara Materials--Every truck trip has two polluting ends.

Double trouble--the other end of the trip

The traffic from s construction site is visiting another location where muddy tracks can occur.

For example gravel comes from Yahara Materials, the Meinholz Quarry #7.  This quarry has multiple violations of erosion control laws, including muddy tracks, no gravel tracking pad, and ineffective sediment fences.  So in effect, you can multiply the 9 tons above by 2--to account for the sediment at each end of a vehicle trip.

What's really needed is a system of high-pressure water sprays to clean wheels before trucks leave the site.

Cleaning tires--
it's not rocket science.

My mother taught me to wipe my feet before I came in the house.  So why can't trucks leaving construction sites wipe their feet before they track muddy footprints into the lakes?

Erosion control plan for the Wingra Clinic, 1102 S. Park St.

Because Contractor Report has documented 13 sediment spills into Monona Bay, plus one extreme dust incident, it's beyond question that either the plan below, and/or its implementation, were flawed. But Ghidorzi and the City signed on to this plan, so knowing the plan is where any investigation starts.  Later, we plan to post a critique of this plan, plus detailed analysis of how it was carried out.

Wingra Clinic--Grading, Erosion Control, and Landscaping Plans C 2.0
By Engineer Wade P. Wyse 
Obtained from DNR via a Freedom of Information Request

"General notes" (relevant parts)

6. All building and waste materials shall be properly handled and disposed of offsite to prevent runoff of material into waters of the State.

"Construction Site Erosion Control Requirements"
I have emphasized in blue the items easiest to observe from outside the site
  1. All erosion and sediment control practices shall be designed and implemented in accordance with the current department of natural resources erosion and sediment control technical standards which are available at
  2. Install erosion control measures prior to any site work, including grading or disturbance of existing surface materials as shown on plan.  Modifications to sediment  control design may be conducted to meet unforeseen field conditions if modifications conform to WDNR technical standards.
  3. Inspections and maintenance of all erosion control measures shall be routine (once per week minimum) to ensure proper function of erosion control at all times.  Erosion control measures are to be in working order at the end of each work day.
  4. Inspect erosion control measures after each ½’ or greater rainfall.  Repair any damage observed during the inspection.
  5. Erosion control measures shall be removed only after site construction is complete with all soil surfaces having an established vegetative cover.
  6. Install a tracking pad 50’ long and no less than 12” thick by use of 3” clear stone.  Tracking pads are to be maintained by the contractor in a condition which will prevent the tracking of mud or dry sediment onto the adjacent public streets after each working day or more frequently as required by the city of Madison.
  7. Install erosion controls on the downstream side of stockpiles.
  8. Install check dams within drainage ditches and in front of silt fencing in any low area all in accordance with WDNR technical standards.
  9. Erosion control for utility construction (Storm sewer, sanitary sewer, water main, ETC.): A. Place excavated trench material on the high side of the trench.  B. Backfill, compact, and stabilize the trench immediately after pipe construction.  C. Discharge trench water into a sedimentation basin or filtering tank in accordance with the dewatering technical standard No. 1061 prior to release into the storm sewer, receiving stream, or drainage ditch.
  10. Install type D inlet protection around all storm sewer inlets and catch basins that may receive runoff from areas under construction.  Refer to WISDOT FDM for respective details.
  11. Apply anionic polymer to disturbed areas if erosion becomes problematic.
  12. Dust shall be controlled on the site per WDNR storm water management Technical Standard 1068 if necessary.
  13. Additional erosion control measures as requested by state inspectors, local inspectors, and/or engineer shall be installed within 24 hours of request.
  14. All slopes exceeding 4:1 (25%) shall be stabilized with Class I, Type B erosion matting and drainage swales shall be stabilized with a Class II, Type B erosion matting, or application of a WDOT approved polymer soil stabilization treatment or a combination thereof, as required.  Contractor shall provide product specifications to project engineer for approval. 
  15. Contractor/owner shall file a notice of termination upon vegetative stabilization and/or property sale in accordance with WDNR and WDCOMM requirements.
  16. Dewatering, if applicable, shall be conducted per WDNR storm water management technical standard 1061.
"Grading and Seeding Notes"

1. All disturbed areas shall be seeded and mulched immediately following grading activities.  Seed mix to be in accordance with landscape plan.

Details shown on the engineering drawing (in my words)
  • The silt fence completely surrounds the site, except at the NE corner, from Park St. to the construction entrance on Midland St.
  • Three construction entrances are shown: One on Park St. (not used, to our knowledge), one on Midland St., and one on Fish Hatchery Rd.  All refer to the standard specs for size and maintenance (item 6). 
  • The N tip of the triangle, at the junction of Fish Hatchery and Park, is to be left undisturbed.
  • Nowhere on the plan did I see any statement that it was permissible to replace sediment fence with silt socks.

Construction dust is a proven health hazard for Madison

"Long term exposure to air pollution is linked to heart attacks and strokes because it speeds up hardening of the arteries, known as atherosclerosis," according to new research by University of Michigan scientists. source

"The vessels of people exposed to higher levels... of fine particulate air pollution thickened faster than others living in the same metropolitan area."

“Linking these findings with other results from the same population suggests that persons living in a more polluted part of town may have a two percent higher risk of stroke as compared to people in a less polluted part of the same metropolitan area."

Madison--24th most polluted

And Madison has been ranked by the American Lung Association as the 24th most polluted city, for short-term particulate pollution--essentially dust and smoke.  This is the same kind of pollution--known as PM 2.5--that was studied by the Michigan doctors.

The many construction sites around town are major contributors to dust in our air.  The particles are blown directly off construction sites on windy days.  High winds during spring shouldn't surprise construction managers.

University Crossing construction site

Much of the dust also comes from mud tracked onto streets by tires of trucks. The mud is spread for miles over the streets--then it's lofted into the air by passing vehicles.

Mud tracked out of Ghidorzi site, Dec. 19, 2012.

The mud also washes to the lakes when it rains, causing algae blooms.  Studies show construction sites contribute 19% of the phosphorus to Madison's lakes.

L. Mendota after storm, about 1968, UW Engineering photo

In winter, you can see the fallout of dust onto the ice of Lake Mendota.

This layer of dust accumulated within a few weeks, soon after the ice formed.

A case study

One recent example is the construction site at the corner of South Park Street and Fish Hatchery Rd, managed by Ghidorzi Companies.  
On April 26, dust from Ghidorzi was so thick that it obscured traffic at the busy intersection, according to resident Steve Vanko.

Throughout the demolition and construction which began last fall, the site has contained large piles of soil and debris, some piles as tall as two stories.  Last summer, Styrofoam insulation blew all over the neighborhood and into Monona Bay, where it can still be found.

The piles have not been protected by tarps, and were screened by only one short fence, often tattered.  Dust suppression with water may have occurred briefly, but was not continued.   Re-vegetation of the large bare area has been repeatedly postponed. 

A hazard for nearby hospitals

On April 26, the dust was blowing towards St. Mary's and Meriter hospitals, located nearby.  Weather records show strong winds often blow from the site towards the two hospitals.  Video of dust blowing towards hospitals.

Patients weakened by illness are more susceptible to harmful effects of air pollution   The American Lung Association estimates that tens of thousands of people in Madison are especially sensitive to air pollution.

It's ironic that the building under construction will house...

  • the Wingra Family Medical Center (Access Community Health Center), and
  • Three UW Health clinics.
Meningitis outbreak kills 23

A national outbreak of this brain infection was traced to contaminated injections, manufactured by a pharmacy in Framingham, Massachusetts.  The infection was caused by a fungus... but how did the fungus get into the injections?

"At least one of the vials confiscated by inspectors from the Food and Drug Administration had so much 'foreign matter' floating in it that it could be seen with the naked eye."  Source

The filters outside the clean rooms at the pharmacy were clogged with dirt.  And located on the same property as the pharmacy was a recycling facility, where what looks like furniture and construction materials were broken up with heavy equipment.  Source  

Investigators were looking into the contributing role played by environmental conditions, caused by the recycling operation.  But it was clear that sloppy procedures at the pharmacy were the chief cause.

That recycling operation was similar to what happened when Ghidorzi demolished and recycled the Bancroft Dairy (below), leaving the piles of debris to blow about, close to two hospitals and many homes.

One resident near Ghidorzi complained that their air conditioner had burned out, due to dust from construction.  Let's hope the hospitals have inspected their air conditioning filters, to make sure they aren't clogged with dirt from the Ghidorzi site.  

Lessons from the meningitis outbreak...

  • Environmental conditions, leading to excessive dust, can play a role in disease outbreaks.  
  • And incomplete inspections--as at the pharmacy--can also play a role.  Most of the erosion control inspections at the Madison site are done by Ghidorzi staff, or their subcontractors.
Development in Madison builds our city.  Construction provides jobs.  But with proper management and inspection, construction doesn't have to be dirty, or harm our health.

Inspection procedures for erosion control need to be improved.  Madison relies on self-inspection by contractors.  When they inspect themselves,  they always get A+.

Findorff Construction spreads litter on L. Mendota

On Sunday March 10, Findorff was again unprepared for rain and thaw.  The rain amounted to .93 inches, augmented by melting snow.

The area furthest from the lake had been recently excavated, but no erosion controls were visible along the fence.

Out on the ice of Lake Mendota, Findorff had been dumping snow excavated from the construction site.  The dumping of snow was intentional--it was in large piles dropped by a power shovel.

Pollution of Monona Bay by Ghidorzi Companies

Steve Vanko and I believe these muddy plumes were caused by construction of the Wingra Clinic by the Ghidorzi Companies.  This construction site is only 1-3 blocks directly upstream on the stormsewer system.  In all cases, we have photographs of the construction site proving deficiencies in erosion control, and showing muddy water exiting the construction site.

#1. July 18, 2012. 1.43 inches

There were two big storms, one during early morning, and the other in late afternoon.  A large amount of plastic insulation was flushed to the bay.

This photo from the morning, shows the 10-15% that remained, after a city Vactor truck tried to suck up the debris.

At about 8:19 pm, the blue storm pipe across the street from Steve's house was dumping mud into the bay.  More photos.

Inaccurate reports by Findorff at the Edgewater reconstruction

Many inspections by a variety of companies, filed on the PermiTrack system run by the City of Madison for self-inspections, are late, missing, inaccurate, or poorly documented.

These errors are so widespread--as to undermine any confidence by citizens that the self-inspection system is working.

Here are a few examples.  Individually they may be small, but together they fostered an attitude of neglect--that led to a sediment spill.

On January 29, there was hard rain, totaling 1.84 inches, with a maximum temperature of 54 F. While unusual, this storm had a precedent.  Anyone planning for this site could see that on Dec. 30, 1884, it had rained 1.62 inches.

Erosion control at the Edgewater reconstruction failed, and sediment was spilled to Lake Mendota.  Photos

Contractors reported for dumping concrete slurry to gutter

Dumping of concrete slurry or washout to the gutter is illegal in Madison.  It's highly alkaline, and may cause a fish  kill, if it washes to a nearby waterway.

Enforcement is by the Madison-Dane County Board of Health, which responds immediately to complaints.  They refer violations to the City Attorney--photos are enough to secure a conviction.

Contractors: Prepare for wind gusts in June

On May 24th, Madison saw gusts of 50 mph, sending billowing clouds of dust from three construction sites we inspected.

March and April are usually said to be the windiest months here--the months with the highest average wind speed.

But it's actually June that's the month with the highest average peak gusts--of 50.7 mph.*  Both June and July have the highest gusts on record--both of 83 mph.

Problems at Findorff Construction site, 3500 University Ave

This site (including the other side of the building) is 1.4 acres, and hence requires an erosion control permit from both Shorewood and the DNR.  Findorff has an erosion control permit from Shorewood.  Karl Frantz of Shorewood is the one responsible for this project.

It's true that rain gardens are being installed in these new parking lots, which will reduce sediment and pollution runoff.  Yet the lifecycle savings in pollution from these gardens must be balanced against the pollution that occurs during construction.

Those gardens may last and provide sediment reduction for 30 years?   Yet, a severe rainstorm during construction could cause as much sediment erosion and loss as 10-20 years of those hoped-for reductions.  In other words, poor erosion control during construction could negate a large percentage of the benefits of a rain garden project.  It's like throwing money down the stormsewer.

All four gravel pads are too short and too narrow.

Stormwater inlets in the streets nearby have no filters.

Concrete washout was poured down this storm sewer behind the Credit Union.  While there was a filter inside, the highly alkaline water will go right through the filter.  It washes to University Bay, and has the potential to cause a fish kill there.

Contractor Report has observed many violations of erosion control regulations by Findorff Construction.

Concrete dust is toxic!


Concrete dust will come back to bite you in the end.

On April 25, 2012, personnel from ALL-TIM-IT Landscaping, Waunakee, WI, were working without dust protection on S. Owen Dr in Madison, WI.

Concrete dust is highly alkaline and corrosive.  It can also cause silicosis of the lungs.

Two small children were present at this house during the work.  One was outside.  The family had not been warned about the danger from dust.

One solution to the dust is to use a saw that is water-cooled.  This converts the dust to a slurry.  However, many contractors do not dispose of the slurry properly.  It is illegal to discard it into the gutter or storm sewer.

Just one example of a widespread problem

The concrete industry is not sustainable, and is headed for trouble.  We have reported elsewhere in this blog about widespread abuse in the disposal of concrete slurry and washout.

The public is frequently exposed to dust from slurry in streets, or the mixing of concrete products.

Wingra springs threatened by heavy pumping

Over the years, a number of springs on the shores of Lake Wingra have gone dry. Vigorous springflow is important, because it helps to keep Lake Wingra clean. Improved spring flow is part of the restoration plan for the lake.

The Odana Infiltration Project, costing over $2 million, was supposed to restore groundwater in the area by pumping stormwater into the ground. But now that project is in limbo, since it was found that the groundwater was being contaminated--over legal limits--from the salty runoff they were pumping.

Still, a number of springs in the area continue to flow--to the delight of residents in the area.

Western Council Ring Spring--a window into a healthy underground.

Now, heavy pumping of groundwater is occurring at two construction sites in the area:

Parman Place at Monroe & Glenway St

The contractor is Landgraf Construction.
The blue hose to the left is carrying the pumped groundwater.

Steve Glass sent me the following report:

You may have heard the recent report that excavation at the Parman's Place project has opened up a large underground water vein or spring (estimated flow rate of >50 gallons per minute, but no one will really know until it is measured with a pygmy flow meter).

According to reports, "the contractor is de-watering the site (under their de-watering permit related to petroleum contamination of the site) and diverting the flow into the sanitary storm sewer."

Also, according to reports, "the contractor expects that continuous pumping will be required to keep the sub-grade de-watered."
These reports and the possibility of continuous pumping raise numerous ecological and hydrological issues for the watershed, the lake itself, and the wetlands bordering it.

There are many unknowns. For example, scientists don't know with certainty the groundwater flow path, so the major question is how will this new spring opening impact existing ground water discharge rates and flow patterns? Increase them? Decrease them? No impact?

Ken Bradbury of the Geological and Natural History Survey has suggested (according to one source) that Parman's construction might disrupt flow to existing springs and pointed to the nearby Council Spring complex just off Arbor Drive in the Arboretum as a possible candidate for disrupted flow.

We have a record of recent flow rates (gallons per minute) for the past few years for the Council Springs complex and will be able to make some comparison of before and after flow rates.

"Continuous pumping" over many years--sounds like a big waste of energy. Could the groundwater be used for heating and cooling.... or for a beautiful fountain?

Next to Wingra Park behind Jac's restaurant

The contractor is Fisher Construction

At this second construction site, there is a lot of groundwater flowing into this excavation, requiring a lot of pumping. As required by law, the flow is being filtered through a large bladder resting next to Arbor Dr.

Water from the bladder is seeping into the storm sewer--hence it's lost from the ground and from the springs.

Another problem is that a lot of sediment is escaping from the bladder, and getting into the gutter. It's only a short distance to the lake. Sediment is the main way that phosphorus gets into lakes, to stimulate noxious weed growth.

Both problems--loss of groundwater and sediment--could be solved if the bladder can be moved to a depression in Wingra Park just across Arbor Dr. In that location (right), the water would return to the water table, and the sediment would be harmless.

 This construction site is violating regulations by leaving the streets very dusty and unswept after each working day.

The pumping at both sites is within a 1200 foot distance from the spring--and may therefore be subject to regulation.

 Teach-in at the springs

David Liebl led a group to the Council Ring Springs to talk about the issues, according to a post on alder Sue Ellingson's facebook site.

Below: East and west branches of the Council Ring Spring.

"The environment" is one product of the construction industry

The construction industry is Madison's largest heavy industry.

When you put up a building, you are creating a nice place to live or work.  You are also affecting the quality of where we live and work.  Nineteen percent of the phosphorus in our lakes comes from Dane County's constructon industry.

This is what Steve Jobs said about a product... your product:

"We've never worried about numbers. In the market place, Apple is trying to focus the spotlight on products, because products really make a difference. [...] Ad campaigns are necessary for competition; IBM's ads are everywhere. But good PR educates people; that's all it is. You can't con people in this business. The products speak for themselves."

-- Playboy interview, 1985

How you treat the environment speaks volumes about the ethics of your business.

Nelson and Nelson Cement--illegal discharge of concrete waste

Left: Slurry escaping down gutter. Right: The "person responsible."
With two releases on two days, Nelson & Nelson is liable for...
fines of up to $4,000.

The contractor was politely notified that discharge was illegal after the first gutter spill.  When I appeared with camera during the second spill, they rushed to place dams, while denying it was illegal.

Discharge of concrete slurry--from washing chutes or cutting concrete--happens all over Madison.  But...

It's illegal  The details...
