Vapor Intrusion Developments and Concerns in CaliforniaMeyers Nave
Vapor Intrusion is the migration of chemical vapors from the subsurface into commercial and residential buildings. Vapors can migrate through soil and into buildings through cracks in foundations, basements, crawl spaces and sewers. In February 2020, the Department of Toxic Substances Control, the San Francisco Bay Regional Water Quality Control Board, and the State Water Resources Control Board issued in draft form Supplemental Guidance: Screening and Evaluating Vapor Intrusion which recommends a consistent approach when screening buildings for subsurface vapor risk to occupants and describes a framework for deciding when cleanup and/or mitigation is needed.
The regulated community expected regulators to finalize the long-awaited Guidance, but that may be delayed now that recent studies performed by the DTSC have emerged showing that the Supplemental Vapor Intrusion Guidance may have gone too far in its estimation of risk. The delay may provide some relief to site owners due to concerns that the attenuation factors prescribed in the Guidance were too conservative and would have made it impossible to achieve closure for sites with soil vapor contamination.

For environmental due diligence firms, 2013 is the year of a new version of the ASTM E 1527 Phase I environmental site assessment standard. And updates to the protocol for Phase I ESAs trigger a period of education and eventually, adjustment. With release of the standard expected in early November, the challenge for environmental due diligence professionals is to be trained and ready to make the switch as soon as the standard is published. How ready is your team to make the transition? What areas are still confusing? Tune into the industry’s leading expert to clear up any confusion on:
-Status of the E1527-13 Standard
-How the E1527-13 Standard differs from the E1527-05 Standard

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Why Do Vapor Intrusion Plots Have Scatter:
Many Variables Involved – Radon Experience
“This paper identified about thirteen factors that can affect radon: …soil moisture
content, soil permeability, wind, temperature, barometric pressure, rainfall, frozen
ground, snow cover, earth tides, atmospheric tides, occupancy factors, season
and time of day.
….. Four factors that influence radon concentrations indoors are properties of the
building material and ground; building construction; meteorological conditions;
and occupant activities. ”

Multiple Regression Analysis Results
• Winter sampling the single strongest variable (stack effect)
• Multivariate analyses explained the majority of the variance in indoor air
concentration using a small number of variables:
– Sampling season
– Sample zone area,
– Sub-slab soil gas concentration,
– Groundwater concentration, and
– Depth to groundwater
– Distance to primary release.
• i.e. TCE indoor (subset of winter data (n=19)) modeled with only four
terms adjusted r2= 0.86; each p< 0.000001.
• Models require confirmation; not enough data available to have
separate training and test datasets.

Conclusions
• Commercial/industrial/Institutional buildings are different than single family
residences in VI behavior
• EPA’s Vapor Intrusion Screening Level (VISL) calculator likely
overestimates concentrations in indoor air by a factor of 100x for subslab
and 10x for groundwater.
• Normalized indoor air concentrations decrease with increasing sample
zone size (square footage).
• Subslab (and indoor) concentrations fall off rapidly with distance to the
point of primary release.
• Soil type affects these large buildings differently than single family
residences
• These results were used to develop a quantitative decision framework

Editor's Notes
The database structure is based on a hierarchy of geographical units starting at the installation, within installations are sites, associated with sites are buildings, and within buildings we define sample zones as enclosed areas where at least one indoor air sample is available.
Then in the sample zones we define there key characteristics such as size, use etc….and have additional tables for groundwater information nearby, and the primary release point – the place where the historical release is believed to have occurred. That might be a pit, or vapor degreaser…..
Conducted service wide data call, 2nd person QC of data entries
ND results have limited influence on the overall shape or distribution of the data. Analysis suggested reporting limit values could be used with minimal effect on outcomes.
A narrow category “strict preferential pathway” defined and populated as “true” only when there was a visually observable, atypical preferential pathway present. Examples included tunnels, utility trench leading directly to source areas and false walls with soil bottoms.
Source strength screen chosen because this dataset provides the best balance between adequately excluding data controlled by indoor sources, while retaining as many data points as possible for analysis.
EPA database is 41 sites, and filtered to just residences; dominated by northeastern and western sites (Colorado and California)
It is conventional in the vapor intrusion field to speak of a normalized indoor concentration as shown here as an “attenuation factor”. Here those factors are portrayed as diagonal lines on a plot of subslab vs. indoor concentration drawn from the EPA residential database to which we will compare our commercial/industrial results.
Note degree of scatter.
Data shown is after source strength screen.
EPA’s database report concludes that 0.03 is the 95th percentile subslab to indoor air attenuation factor but VISL calculator still uses 0.1
Sample Zone Averages; shapes are individual bases
Explain VISL = vapor intrusion screening level.
EPA’s VISL calculator applied to commercial buildings would suggest you may reach a problematic indoor air concentration with a subslab concentration as low as 470 ug/m3 but our analysis shows not until 100,000 ug/m3
EPA’s database suggested 0.03 for residences, but they use 0.1
We recommend 0.001 AF for military nonresidential buildings.
Similarly, EPA’s calculator would suggest that concentrations as low as 30 ug/m3 may be problematic in commercial buildings, while our database analysis suggests 2,000 ug/m3.
Using the 0.001 attenuation factor EPA’s VISL calculator suggests concentrations as low as 47,000 ug/m3 in groundwater vapor (65 ug/l). We recommend a screening level 10x higher as shown by the dotted blue line be applied to DoD buildings.
WEPA’s application of a 0.001 residential based attenuation factor to commercial buildings leads to groundwater vapor screening at 3,115 ug/m3 or 6.4 ug/l. We recommend a screening level 10x higher be applied to DoD and similar commercial/industrial buildings.
We frequently turn to the decades of experience and research in the radon industry for a perspective on what to expect in chemical vapor intrusion studies. This review of the radon literature makes clear that radon VI is far from a simple process. So when we try to understand why commercial/industrial buildings behave differently from single family residences, we shouldn’t expect there to be a single answer!
This graph shows the TCE Normalized Indoor Air Concentration (subslab to indoor air) vs. Sample Zone Area (both on log scales), it is after the source strength screen and screening out of atypical preferential pathways. While the data shows some scatter there was a statistically significant effect (p=0.009) although the r2 indicates that this single variable only explains about 8% of the total variation in indoor air concentrations. Note for comparison that the median US new single family house is around 2,100 sq ft (census bureau).
EPA’s database of residences does not include many buildings where a release of contaminants occurred on the property. Rather it consists primarily of buildings at a considerable distance from the point of release. Our DoD database though does include many buildings at which the release occurred or immediately adjacent to it. We observe a very strong drop off in subslab concentration over the first 100 ft of distance from the point of release. This variable is one of the best single variables to explain vapor intrusion variability – explaining 37% in the variation of the subslab concentrations.

In the residential cases, where the majority of VI is believed to be coming through groundwater fine soils have a weak protective effect (< 1 order of magnitude difference in the recommended 95% value). In the DoD buildings where the releases likely occurred close to the buildings the opposite effect is seen in both subslab and indoor air. The effect is quite significant.
