St Louis IKEA Phyto Buffer Zone pt2

The magic happens before the toxins and pollutants go into the St Louis storm water system.

Plants and the Plant Roots phyto-extract the toxins that washes into the riparian buffer zone from the parking lot of the IKEA store in St Louis.

Elevated drainage point in buffer zone gives the phytoremediation plants root systems the time needed to absorb the toxins.

(part 1 citizen science) I didn't actually get down into the plants to inspect at close range for fear of being reported to the police and hauled to jail for trespassing.  I was close enough to guestimate the exit or outlet point height above the gravel bed root zone at around 12 -16 inches.

I have been focusing on how the plant roots clean the water.  There are additional benefits on incorporating green spaces into a property design: Control Soil Erosion, Slow the amount of water entering the city sewer drains eliminating "overcrowding or Peak Loads", Reduce backups into Residential and Commercial properties, Improve aesthetics, Inexpensive (my 2nd favorite-phytoremediation is 1st).

The following CAD diagram provides a cross section of the unseen areas where the plant roots phytoextract the waterborne pollutants.

The Philadelphia Water (PWD) Stormwater Management Guidance Manual (the Manual, or SMGM) is a comprehensive resource for the development community in complying with the PWD Stormwater Regulations (Stormwater Regulations). The Stormwater Regulations require on-site stormwater management for development projects above a certain size, helping to improve the health and vitality of Philadelphia’s waterways along with the City’s own sizable clean water investments. Other types of construction activities may also trigger portions of the Stormwater Regulations, including demolition and voluntary stormwater retrofit projects. http://www.pwdplanreview.org/manual/introduction

The following land uses are considered to have a potential for contaminated soil, which may adversely affect the quality of groundwater discharging to surface water. These uses may qualify a project site, or portions of a project site, as a hotspot.

• Sites designated as Comprehensive Environmental Response, Compensation, and Liability Act sites, also known as Superfund Sites,
• Auto recycler facilities and junk yards,
• Commercial laundry and dry cleaning facilities,
• Commercial nurseries,
• Vehicle fueling stations, service and maintenance areas,
• Toxic chemical manufacturing and storage facilities,
• Petroleum storage and refining facilities,
• Public works storage areas,
• Airports and deicing facilities,
• Railroads and rail yards,
• Marinas and ports,
• Heavy manufacturing and power generation facilities,
• Landfills and hazardous waste material disposal facilities, and
• Sites located on subsurface material such as fly ash known to contain mobile heavy metals and toxins.

Suggestion on Designing a Riparian Phytoremediation Buffer Zone for the St Louis Region: 

• Rainfall Distribution 50 years of rainfall data for St. Louis, indicates that 90 percent of all rainfall events are 1.14 inches or smaller. 
• Communities with large geographic areas may find it beneficial to obtain data from different areas in a community to account for variability in rainfall patterns. 
• Rainfall data sets and distributions can be derived from weather service organizations such as the United States Geological Survey (http://mo.water.usgs.gov/) Cumulative Rainfall Distribution for St. Louis, MO,

IKEAs lesser known environmental project

If only more business cared about the environment as much as IKEA does.

Most everyone has heard that the St Louis IKEA Store is powered by solar panels!  Here is a lesser known environmental project they have incorporated into the property along Forest Park and Vandeventer Streets.

The parking lot in of the St Louis IKEA store drains into a low $$$ cost natural phytoremediation filter system.

The IKEA's Engineers and Crew that installed the water filtration Phytoremediation project did a seamless job of blending the bioremediation system into the natural environment.  If it wouldn't have been for my growing the Kenaf plants and seeing the unmistakable Kenaf Flowers- I may not have noticed. 

IKEA Store Flags and Kenaf Flowering Plants used modified Riparian Buffer StLouis 

IKEA Parking Lot drains away from the building into modified riparian buffers along Forest Park Parkway and Vandeventer

Any contaminants that escape or drip from the Autos in the parking lot will eventually make their way into the modified riparian buffer zone that removes the toxins naturally

The break in the concrete curb allows the water to enter the riparian buffer zone where the Plants naturally cycle the toxins from the water.

Phytoremediation Plants are growing in a bed of Gravel and Rock allowing the roots of the plants direct contact with the toxins that will be removed by Phytoremediation.

 In ElectroHemps IKEAs next sustainable bioremediation post (publication date 9/1/16) I will explain with photos, diagrams, and CAD drawings how the water toxins are removed before entering the public water system.

Toxins and Contaminants are removed the Natural Way by using Plants in a process called Phytoremediation.
