What Are Spill Sites?
A spill site is created after a chemical spill is reported to a government agency. WhatsDown currently holds approximately one million spill sites. Spill sites, for example, involve gas stations where fuel tanks leaked, dry cleaners where cleaning solvents spilled, industrial locations where chemical spills occurred in the process, and others. Spill sites can affect small areas or very large properties or groups of properties. Spill sites can also be due to very old spills, even dating back dozens of years or longer, as well as new ones.
How Are Spill Sites Shown on the Map?
WhatsDown shows points to locate spill sites, but please note that spills always affect an area rather than an actual point. In addition to locating the spill site, WhatsDown shows the cleanup progress as being incomplete or complete. Ordinarily, government agencies oversee cleanup activities which eventually reduce the chemical concentrations in the soil or the groundwater. Cleanup activities, for example, might include excavating the chemicals in the soil, pumping the contaminated groundwater, consolidating and “capping” contaminated soil, or allowing natural decomposition to occur. The complete status divides into cleanup with environmental protections or without. This is because government agency cleanup standards vary ranging from full cleanup that allows for unrestricted future use to more lenient “risk based” standards which allow some contamination to remain in place if environmental protections, including restrictions on the future use, are added to guard against exposure.
What Can I Learn in the Spill Site Information Window?
Shows the name of the spill site, the address where available, and a cleanup status icon. You can use the tabs in the information window to learn, share and ask about the spill site.
Where Does WhatsDown Get Spill Site Information?
Terradex obtains the information for WhatsDown from government agencies. We periodically refresh the data. You can check when we last updated the data, or if we are aware of site lists that we have not yet loaded to WhatsDown.
What Are Groundwater Plumes?
Groundwater is any water found beneath the earth’s surface. Groundwater can fill the space between soil grains or rock fractures, and it can exist at varied depths. A groundwater plume contains chemicals that have seeped into the the groundwater at a spill site and then diffused to contaminate a larger area.
Groundwater plumes pose health hazards in numerous ways. Some groundwater plumes contain cancer causing chemicals that can vaporize into basements or indoor rooms, much like the process of smoke rising. Chemical plumes can also pollute drinking water that comes from groundwater.
How Are Groundwater Plumes Shown on the Map?
The extent of a groundwater plume is typically determined by testing where the chemical concentrations diminish to safe levels set by government agencies. The plume boundaries are never precise. Boundaries are interpolated estimates based on discrete monitoring points.
How Can You Use the WhatsDown Information Balloon?
Touching or clicking a groundwater plume, shown in pink on the map, opens an information balloon. The party that is responsible for the spill’s cleanup appears at the top.
You can use the tabs in the information balloon to learn, share and ask about the plume. You can even order a test kit, to test for vaporized contaminants in the air at home or work.
Where Does Information on Groundwater Plumes Come From?
Terradex uses a variety of approaches to estimate the extent of a groundwater plume. We trace plumes from reports submitted by the polluting parties, we draw a plume shape around a study area, or we obtain a plume map from trusted parties. Plume boundaries change slowly. We welcome input on a plume to improve its location.
What Are Environmental Protections?
Environmental Protections are legal or physical controls, sometimes dubbed “institutional controls” by regulatory agencies, that guard people from unsafe exposure to contaminants at spill sites. Environmental Protections are put into place when government agencies allow spill site cleanups to occur under so called “risk based” standards, which allow some contamination to remain in place if environmental protections are added to guard against exposure. Environmental Protections limit activities and future uses that could pose health or environmental hazards. These protections ordinarily last for as long as contamination remains in place, which could be for many many year, even permanently in some cases.
WhatsDown shows Environmental Protections in “caution” yellow, indicating proceed with care. Environmental Protections often address a single parcel of land, but also can cover much larger areas when, for example, groundwater or soil contamination spreads across multiple properties. WhatsDown increasingly attempts to map the boundary of the Environmental Protection. Otherwise, WhatsDown shows the Environmental Protections as a point on the map.
Government agencies ordinarily require Environmental Protections to be tailored to the hazard. For example, if contaminated groundwater would inadvertently be used for drinking, the protection could be a drinking water restriction. If there were chemicals harmful to children, then protection could restrict use for schools or daycare. The protections are assembled based upon specific risks posed by the spill site. Not all spill sites have protections associated with them, especially those where cleanup has not been completed.
How Can the Environmental Protections Information Balloon Help?
Environmental protections often carry the name of the party responsible for the spill. When addresses are available, they are shown below the protection.
You can use the tabs in the information window to learn, share and ask about the spill site.
Where Does WhatsDown Learn About Environmental Protections?
These protections are often listed in registries at state or federal websites. When protections are shown as points, Terradex will review the documentation and convert the location to a mapped boundary.
What Are Munitions Areas?
Explosives hazards exist in munitions areas. Across the United States there are more than 10,000 properties affected by munitions on current or former military defense sites. These properties are known or suspected to contain military munitions, discarded military munitions, or munitions constituents. Site examples include former ranges and munitions burial areas.
You might notice areas shaped like fans over water or land. These are firing ranges, and unexploded munitions could be in soil or water.
If you believe you have encountered munitions, proceed with extreme caution, because munitions areas can be very dangerous. There are 3Rs for explosive safety:
For construction workers, special precautions can be taken to screen a work area to avoid encountering munitions while excavating.
How Can the Information Balloon Help?
The information balloon provides a name of the munitions area.
How Are Munition Sites Shown on the Map?
Munitions areas are shown as boundaries. Often they overlap.
Where Does WhatsDown Get Munitions Information?
WhatsDown displays maps from the 2012 Defense Environmental Restoration Program Annual Report to Congress by the US Army Corps of Engineers. The Army Corps manage the cleanup of munitions sites.
Testing the air you breathe for volatile chemicals may address your health concerns. Testing is designed to identify vapor hazards due to underground contamination. If, however, vapor hazards originate from hazardous materials stored inside the living or work space, testing may identify these hazards as well.
(1) Enter your location, (2) click a spill or plume on the map to display information balloon, (3) choose the "Chemicals" tab and push "Shop" to find a test configured for the chemicals in the spill or plume. The configured sampling device ships to home or office.
How to Find the Right Test Using WhatsDown. The WhatsDown map locates spill sites or plumes that may be sources of vapor hazards. Click spill or plume, then find the chemical tab, and launch the "test" button. The test button brings you to our shop. Arriving at the shop, the testing is preconfigured for the spill or plume. To finish just add the test to your shopping cart, and within several days the test kit arrives.
Terradex Can Suggest The Testing for Your Location. Just ask, and we will recommend a test, or offer feedback if we deem our test inappropriate to your concern. If helpful, Terradex can arrange a technician to come to your work or home to collect the air sample. Start getting help by following this Get Started link.
How Does Air Testing Work? A sampling test kit is mailed containing a sampling pump, sample tube and instructions. After attaching the sample tube into the pump, place the sampling apparatus on the lower floor or basement. Push the on/off switch and run the sample pump for 2 hours. Disassemble the apparatus and package the sample tube, then return using the shipping box addressed to the lab with the postage-paid shipping label.
Terradex relies on Prism Analytical Technologies, Inc. to perform the customized analysis in accordance with accepted protocols. A report shows the concentrations of the chemicals associated with the spill or plume compared to applicable guidance. The report suggests protective steps, and Terradex is ready to answer any followup questions.
