Al-Tech Steel and the Kromma Kill Watershed

Intro:

The Albany area is supported by the Kromma Kill Watershed. Al-Tech Steel was a hazardous factory that closed in 1994 (http://wikimapia.org/1836689/Al-Tech-Steel-Abandoned). It has since become a Superfund site. By "superfund", I mean a hazardous brownfield that must be cleaned up as part of the Superfund Act in order to protect human health. The EPA plans to clean the area in 2015. Below is a photo of the factories area (Siena College is under the zoom key).

The company was famous for using heavy metals within the factory (especially nickel). But, because the factory used heavy metals for so many years and now they are just sitting there until clean up, it is expected the hazardous waste is going into the soil. That is why I collected soil samples from areas around the outside of the abandoned factory. Using X-ray fluorescense I will test the quality of the soil and make infrences on how the company has affected the area.

Besides soil, a stream that collects a large amount of water throughout the Kromma Kill watershed is just across the street from the factory. In figure 3, the stream is behind the trees which is just across the street from the factories main gates. What is important is that the stream then dumps into the Hudson River, but not before traveling through several neighborhoods. If the water comes back with dangerous levels of heavy metals it could already be endangering the locals' health.

When I was examining the stream I noticed an area dumping into it as well. That is why I also decided to test the dumping water as well as the stream water.

I ended up collecting just four samples (mainly because I only had enough room to carry that many). I collected soil from an area close to the factory gates and next to the stream. Then I collected one water sample from the stream and one from the dumping area. Each sample was run through the HD Prime 3 times. If any samples came back significantly high, I will then go out to form a larger study on the topic. I will decide what constitutes high levels based on the average soil chart  I used before and the standards for aquatic life in water. Below are the charts I will be using.

Data/Soil:

Figure 8. Factory soil 1.

As above average, Zn above average, Cr above average, Cu above average, Mn above average, Ni above average, Pb above average, Rb above average, Sb above range,

I could not find any thing on Fe, but I did read that a lot of it comes from steel mills.

Data/water:

Note: Cr can be as high as 20 ppm in rivers, but most often around 5 ppm. Pb has a zero tolerance level. These things are not listed in the chart.

No data.

Conclusions:

Based on observation, i would say that both sample sets contained soil that was well above safety regulations. Surprisingly the water was not nearly as toxic as I suspected. Elements that concern me are Fe, Hg Pb, and Sb. Fe came in very large quanitties. Online I found that any substance where Fe makes up half of it or more is considered lethal. Several samples of soil also contained Hg which is very alarming. Lastly, Pb and Sb constantly appeared to be to high in both soil and water.

Graphs on Albany Pine Bush Water and Soil Samples

SOIL

After plugging in all of the data points collected from the Albany Pine Bush, you can see a comparison of element concentrations between soil samples. The graphs show the amount of each element found within the samples. Note that each sample was ran twice on default (example: sample 1 and 1.2) and once on extended (example: sample 1E). The first graph mainly shows the highest element concentrations. In the second graph I deleted the two highest element concentrations (Ba and Cl) so that smaller peaks could be observed.

To get an even closer view of the remaining elements I again deleted the next two largest elements (Sb and Pb).

Again I deleted the next highest element (Cr). Also note because Hg and Cd only had ND as its results, no numerical stat apeared. ND stands for "no data", but what that actually means is the concentrations were so low they could not be detected.

From these graphs we can see just how much higher the concentrations of Ba and Cl were as compared to any of the other elements. We as well can visually see which elements had lower concentrations (As, Br, Cd). Although Ba and Cl were the highest, they had large variation as compared to Cr and Sb that were consistent throughout the samples. Below is the data I collected on the averages of all the elements. One thing that should be noted is that the averages only include data from numerical values and ignored ND. Because ND generally is a very low amount, the averages are not very reliable.

WATER

For the water samples I used the same idea when making graphs. The first graph includes Cl that was very high only in one sample. In the second graph I removed Cl so that other elements can be looked at.

Below is also the averages computed for each element. Again the averages only included data with numerical values and ignored ND.

Comparing Albany Pine Bush Water and Soil Samples to Each Other

Comparing Albany Pine Bush Water and Soil Samples to Each Other

 Into:

After examining the Albany Pine Bush's water and soil independently, I will now compare them to each other. The water samples came from a natural well and the soil samples came from close by (approximately 1 m away from each well). I can look to see if there is a pattern with the soil and water, where they share high concentrations of the same elements. With these comparisons I will be able to link data sets produced from the HD Prime. A strong link would prove both the accuracy of x-ray analysis, but also that correlation between water and soil.

Data:

• Note- The first data set belongs to soil and the second one is water's. Also I will be referring to                   comments made from previous blogs.

Sample 1-

 Low shrub area, houses near by

Both sets have high levels of Sb.  While in soil Cl is high, Cr is relatively high in water.

Sample 2- 

Shrub/wooded area, recent control fire

Cl ia above average is soil along in soil and most likely water. Both have high levels of Sb. 

Sample 3-

Shrub/wooded areas, control fire, near highway

Sb is high is soil, but not in water. Cr and Ba is high in water.

Sample 4-

Same as 3

Sb is high in soil, Cr is high in water.

Sample 5-

Low shrubs, near landfill

Sb is high in both samples. Cr is high in water.

Sample 6-

Same as 5, also near wetlands

Sb is high in soil. Cr is high in water as well as Pb (has a zero tolerance law).

Sample 7-

Same as 6

Sb is high for both and Ba is relatively high for both.

Sample 8-

Same as 6

Sb is high for both. 

Sample 9-

Especially close to landfill

Sb is high in soil. Pb is an issue in water.

Sample 10-

In swamp, near landfill

Ba readings are high in soil. Sb is high in both.

Sample 11-

Same as 10

Sb is high in both sets. Pb is an issue in water.

Sample 12-

Near Albany Pine Bush Center, close to parking lot

Ba is high in soil. Sb is high in both sets.

Conclusions:

Seeing as almost every sample came back with high Sb readings, it would be safe to say that Sb is an issue in the area. 8 of the 12 sets came back with readings that were high for specific elements in both the water and soil (example: both had high Sb readings). As well, water with high Pb readings came from landfill areas. There does not seem to be any outstanding concentrations of heavy metals from areas closer to the landfill as compared to wooded/natural areas. My best guess is that there is leeching going into the soil first that then makes it into the water. This becomes more apparent when the heavy metal concentrations is almost always higher than the water readings.
