I'm studying for the Environmental FE, and I can't find that much information about groundwater remediation techniques, but I know it will be on the test. Any help would be appreciated, thanks!
Hi guys. Can anyone suggest a good book on soil and groundwater remediation. Have a job interview coming up.
I'll be up for a few hours and will be back in the morning.
I noticed there was a second environmental engineer, specializing in surface water and USTs - so there is some overlap and differing opinions. Thus, I wasn't sure if it was proper to jump into that thread as well or just start my own.
For starters, I am in the 3-5 year range but have worked several sectors of the job. I've done lab research in recreational surface water quality, spent some time working for a regulatory agency, and worked private/semi private.

tl;dr / summary
The Marshall Fire currently burning now covered in snow, known as "the most destructive fire in Colorado history," is directly over the top of known plutonium contamination, generated by radioactive waste leaking from barrels, courtesy of the Rocky Flats Plant. This facility manufactured the bulk of the plutonium pits (nuclear weapons triggers) in the height of the Cold War. In the past, strong wind events were known to spread radioactive particulates from this site and activists -- including the very FBI agent who led the historic raid on the Rocky Flats Plant -- have been sounding the alarm on this inevitability for years.
This story is a breathtaking example of the truth being stranger than fiction. In a series of events from the 1950s all the way up to the present day, there have been a series of cover-ups by the U.S. Department of Energy, its subcontractors Dow and Rockwell, the Justice Department, and at least two generations of property development powerhouses.
The clean-up effort was originally projected to take 65 years and $37 billion to do properly, but after only 10 years and $7 billion (most of which went to administrators), the clean-up effort was heralded as a success and the superfund site was opened up for both property development and recreation.
One might argue the clean-up effort was half-assed or even deliberately negligent. For example only the top 3 feet of contaminated soil was cleaned up, even though contamination is known to be much deeper and natural processes routinely bring up soil from 16 feet and below. This is the case even when excluding criminal dumping and incineration of radioactive waste clandestinely undertaken by the plant. (As an aside, uncooperative employees were known to have been deliberately exposed to "infinity levels" of radiation.) For nearly the last 20 years, there has been insufficient testing and monitoring of radioactive contamination in the area, which again is driven by commercial interests in th

Hey everyone wanted to get some feedback for any of those who live near on a remediated brownfield in NJ. Looking to move into an apartment but noticed that it has an area of contaminated groundwater from historic fill. Additionally the site was apparently home to a wood furnishing company and later on a paper box manufacturer. The previous uses apparently dumped some solvents into the soil. The site was cleaned up under an LSRP prior to the construction of the residential buildings. What kind of risks am I looking at considering previous use as well as current groundwater contamination? Should I be considering vapor intrusion and cancer or am I looking way too deep into this? Thanks in advance!
Howdy,
This is going to be a look into AEC, a comparison of AEC vs incumbent technologies, a look into other emerging remediation options, breaking down the status of both state level and federal level PFAS remediation, a look at existing PFAS remediation projects to try to give some context to the advantages that AEC provides as well as the potential size of project that AEC/PFAS remediation brings to BioLargo. Follow the embedded links for more context.
AEC - The PFAS Collector
https://preview.redd.it/pvz13nfbt5e81.png?width=531&format=png&auto=webp&s=7736e27cd51b04317a41ba80a9cccb6ccc8ac5f3
AEC is a collection device that relies on electrical current and a specialized membrane. Water is run across the membrane and specific PFAS compounds are drawn to the membrane. Dennis (CEO) has in the past compared it to fly-paper for PFAS, though notes that the scientists in the room would hate that description. AEC removes 99.995% of PFAS compounds from water (testing validated by University of Tennessee).
AEC was developed with help from an EPA SBIR-Phase I Grant: EPA Final Report
AEC was included in a short list of emerging technologies in the EPA's Multi-Industry PFAS Study - 2021 Preliminary Report. While this isn't an endorsement by the EPA, I'm very pleased to see AEC highlighted in official publications.
AEC has a modular design, and the company speaks confidently about the scaling capabilities of AEC. It can be integrated with existing water treatment with a very small footprint (roughly 10% when BioLargo's estimate is compared to a real project listed below) as well as integrated into mobile container units.

... keep reading on reddit ➡Geophysicist/Geologist here... Recently finished season one. The episodes where they perform & interpret geophysical surveys, then conduct a drill program based on the data were absurd.
- Travis's interpretation of the GPR data as indicating a large 'football shaped object' was a stretch to say the least. Yes, parabolic anomalies indicate subsurface structures or objects, but the profile we were shown indicates multiple objects or an irregular surface. What they were seeing was pretty obviously the surface of bedrock, or boulders/float along the weathered overburden/bedrock contact. Could be other stuff too, like a buried garbage dump, but there was no real justification for "connecting the dots" into a flying saucer shaped object. I'm guessing this is why the head geophysicist was so vague in his interpretation when pressed - he was probably asked by producers not to spoil the fun, but didn't want to ruin his reputation by encouraging a crackpot theory either. If the object had been a uniform, continuous, perhaps metallic surface as theorized, the GPR profile would have reflected this. Also, if one had any reason to suspect there was a metallic object buried there, you'd run Mag survey...straight up. But I guess mystery makes money.
- Despite the uncompelling geophysical data, they brought in an auger rig to ground truth the anomaly....Why? These rigs are only designed to split spoon sample overburden soils for engineering and environmental purposes. They can't penetrate bedrock, concrete, or flying saucers so the inevitable result in either case was to encounter refusal and TD the hole without sampling the anomaly - which tells you absolutely nothing about the anomaly itself.
- I don't know much about EM and radiation surveys, but if this is how they approach geophysics I assume most of their data interpretations are, well, dubious.

Help! I got a letter from the Dept of Environmental Quality in Utah saying that there is a toxic plume from a historical dry cleaning business on the next block and that I need to have my indoor air tested to see if toxic fumes are getting into my house. The letter says that they found this out in 2001 (20 fucking years ago!). And when I called the project manager on the case he said that a house across the street from me tested positive for toxic fumes in 2016, the year I bought the house. He said whoever was working on the case dropped the ball (and are no longer employed there) and that’s why none of the other people on the street were notified. If I had known it was a potential health hazard, I obviously wouldn’t have bought the house. I don’t believe they informed the seller or the seller before him. Pretty sure my property value is totally fucked now. Can I sue them for negligence for the difference between my market value and the price it actually sells for after disclosing this info to a buyer? This is my life’s savings in this house and I was planning to sell in the spring to move out of state.
TLDR: Dept of environmental quality knew groundwater was toxic and didn’t tell anyone and now I’m going to lose money on my sale. Can I sue them?

OP $BLGO Great to see them spreading the word. FYI - If BioLargo gets any share of the PFAS remediation market - we will have hit the clean tech Jackpot.
Companies Race To Develop Solutions to Eradicate Pervasive PFAS
The pervasive man-made chemicals known as per- and poly-fluoroalkyl substances (PFAS) continue to draw attention in the courts, public domain, water systems, the White House and U.S. Congress. Recently, legislators have again held hearings on what to do about PFAS — a chemical by-product in the manufacturing of everything from frying pans to firefighting foam — and are still looking for a feasible solution to eliminate them from the water we drink.
During a congressional hearing, U.S. Rep. Melanie Stansbury (D-New Mexico) asked for solutions to the impacts of PFAS contamination of groundwater on dairy farms.
“Thousands of gallons of milk have been dumped and people’s livelihoods have been destroyed by this contamination,” she said.
Historically, PFAS have been used in the manufacturing of countless industrial and consumer goods including non-stick pans, waterproof outdoor gear, and firefighting foam. But because the PFAS are resistant to breakdown by natural factors like UV light, they are persistent in our water, food, and bodies.
Research shows trace amounts are already inside most people — if not all — in the U.S. A recent analysis of an Environmental Protection Agency (EPA) database revealed that Colorado has about 21,000 industrial sites that may be handling PFAS, more than any other state.
The prevalence of PFAS in our daily lives has led companies like Agilent Technologies Inc. ((A) to develop what it calls a complete start-to-finish workflow for extraction, screening, quantification and reporting of PFAS in water and environmental samples to make it easier for municipalities to get a grasp of their contamination problem. The Environmental Group Ltd. (ASX: EGL) has also reported positive results from its commercial PFAS water treatment trial with Reclaim Waste.
BioLargo invents, develops and commercializes innovative platform technologies to solve challenging environmental problems sustainably and affordably. The company has previously developed eco-friendly technologies for air quality control and water disinfection. BioLargo is now commercializing a new proprietary technology that eliminates PFAS from water.

Consumer Products:
Ikigai Holdings, LLC, which was founded by accomplished industry executives from the consumer-packaged goods industry who have executed successful launches of at least five blockbuster products, has licensed and begun testing a television commercial it developed for a CupriDyne-based household pet odor removal product and a laundry additive for pet related odors under brand name “Pooph”. It will evaluate testing results, and has advised us that if its test marketing phase is successful, will launch the product with the goal to sell to the major retailers in the United States (e.g., Walmart, Target, etc.). Ikigai has represented that subject to the successful launch of these two initial products additional products would be considered. Ikigai has reported that in its first week of test marketing that Ikigai was seeing “very promising results”, and that the next few weeks would be critical in evaluating their expectations of volume and velocity, two critical metrics to support expanded investment.

TLDR - The need of ethically sourced rare earths from allied nations is paramount. There are environmental issues (leachate from tailings dams, erosion and radioactivity to name a couple) at rare earth mines such as the Bayan Obo mine in China, Mountain Pass in California and Mount Weld in W.A but of these issues are of different scales. EU and USA have regulatory bodies investigating supply chains which will be meet U.N guidelines whilst also provide them with autonomy. The means of achieving such independence include sourcing materials through recycling to produce rare earth elements to some effectiveness which does lessen dependence of certain producers and decreases waste simply through re-use such as NEO tsx, NMT asx and LIT asx. Some companies are trying to eliminate the need of rare earths altogether (Honda and Jaguar for example). The question is are non-ree-ev cars better? The general consensus is no. If recycling doesn't meet production quota's is - environmentally friendly REE mining. Sure, the plant will still need diesel for years (even the plant will be EV operated eventually) but it is way more environmentally friendly than it used to be. The companies which still rely on them if they still require rare earths - there is sorting equipment such as TOMRA (VML) and Steinert (NTU) which eliminate the need of tailings dams and deplete the radioactive run off risk.
Ok this is going to be ranty as fuck but - u/BuiltDifferant asked me a good question yesterday about this specifically within the yesterday’s daily (my answer being VML and they knew about it already), so no worries mate, I'll put my useless framed piece of paper that says "Bachelor of Environmental Science" - with a geography and geology double major (and yes surely there are plenty here who will be way more qualified in this field of almost 80 k members because I'm just have a bachelor degree - and some may nit-pick and have even better suggestions, which is fair enough (this is what makes democracy good) - so I admit I am FAR FROM AN EXPERT IN THIS FIELD), but anyway, I may as well use my toilet paper degree with

submission statement :
I know a lot of jokes can be had at Staten Island expense, I'm writing about a serious matter, and hoping whomever reading this might be interested to read a report made by the national park service, and hopefully compelled to sign a petition to expand testing and expedite the clean up.
background:
federal parkland gateway great kills park has been closed in part for over a decade, after the finding of radioactive and other hazardous material in the soil. A report made in 2017, which has not seen any press suggests the contamination could be spreading to other areas outside the park. Including other parts of NYC, when contamination is released through waterways.
excerpt : 5.4.1. Potential Receptors
" . Potential human and ecological receptors may also be exposed to sediment generated from Site surface runoff to Site surface water bodies (drainage channels) and sediment transported to adjacent surface water bodies including Great Kills Harbor, Lower New York Bay, and Raritan Bay. "
more Staten Island specific excepts regarding spread include :
- Rain and flooding is potentially spreading radioactive and hazardous material to neighboring communities, groundwater, and areas used for swimming, boating and fishing.
- Specifically notes off site residents, especially residents within 200 feet of Gateway Great Kills Park to be "potential receptors" of any spreading contamination.
The full report can be found here :
https://www.nps.gov/gate/learn/management/upload/2017-09-01-Draft-Final-HSA-RS.pdf
If you are moved to help test where contamination might be spreading, and help put pressure to get this park cleaned up and open please consider sighing this petition.
Hi! I'm an environmental engineer in my 3rd year as working in a position dealing with remediation from soil/groundwater contamination. I feel as though I'm lacking in the basic understanding of chemical reactions. For example, I understand that a permeable reactive barrier (PRB) for copper in the groundwater can use the material calcium carbonate, but I only know this because I saw another example. I just don't understand anything about why this is the case. I would like to know more about contamination chemicals, and be able to identify treatment options and basic properties of the chemicals. Other people I work with can quickly identify for example, that limestone and shell fragments can cause dissolved lead and copper to precipitate in a PRB. I literally don't even know what that means, and I'm really embarrassed by it!
I guess my undergrad was more focused on civil engineering and structures, so I missed some vital courses. I'm trying to identify which courses I should take to become a better engineer in my profession. Thanks!
Hey everyone,
Thanks for the wonderful insight regarding looking at my resume the other day - I am currently in the process of revamping your suggestions (have to finish a manuscript first!). I also took down the post because it was pointed out that I accidentally kept in some personal info.
Anyways, the stars may be slightly aligning in my favor but I would love some insight from you folks here. So, my friend's brother in-law is head of IT at an engineering firm that is close to my house. He sent me an email asking me to check for any positions that I may be a good fit. Now, I know that does not mean much, but it certainly is a start.
The only position that I see that I probably qualify for is for an Environmental Project Manager position. The responsibilities include
Manage multiple site remediation projects and project personnel
• Management of remedial investigation/actions, including but not limited to groundwater, soil, and vapor intrusion
• Preparation of NJDEP-required reports and forms
• Compliance with NJDEP regulatory and mandatory timeframes
• Liaison with federal and state regulatory personnel, including meetings and on-site inspections of investigation/remediation projects
• Project management including proposal preparation, budget tracking, and invoicing
Having not found employment outside of academia (as an adjunct) since graduating with my PhD and despite looking for jobs in environmental firms, NGOs, and the govt, I am feeling a bit of imposters syndrome so I am always unsure if I qualify for positions that are listed.
With all of that out of the way, for those of you work/worked as an Environmental Project manager. Can you provide some insight on what your day to day experience is like? In addition (and I apologise if this is awkward) but given my experiences highlighted in my resume found here , do you think I may qualify for such a position given my own experiences?
I absolutely apologise for asking something as vague regarding if I were to qualify for such a position, but even some insight would be greatly appreciated because I wouldn't want to apply (especially because I have a connection at the company) for something I may not feel qualified for. Although, as mentioned earlier, I believe I do overall qualify given the job requirements.
Thank you!
Hello,
As the title suggests, I'd like to hear from any geologists (particularly environemntal-flavored) who struck out on their own to conduct business independently. What't it like? This is mostly a thought experiment.
I've been at a large environmental consultancy for 5 years and I essentially have my PG now (as in, the tests are passed, the paperwork is in, the fee is paid, and the application should be accepted any moment now). On balance, I like my job, my boss has basically all but promised me the biggest raise I will have ever gotten after I passed the PG. There are plenty of things I don't like about being in a big consultant, too. I bet at this point we can all guess what the pros and cons are.
I do not know it all, and I understand most independent consultants are probably sitting on 20 years experience. I'm not looking to remediate a 5 mile groundwater plume alone. I'm interested in simpler due diligence projects.
Just like everywhere else, the real estate market in my area is on fire. I've done 3 Phase I ESA site recons for major residential developers in the past week and there are more coming down the tubes. I will probably have inspected 1,500 homesites in 2 weeks at the end of it.
I'd love to hear from somebody who has tried to become their own Phase 1 mill. It's kind of a crappy deal for large companies like mine... low budget/profit, moderate to high risk, short schedules. But I imagine if I was my own PG with the appropriate insurances, I could wear out some Phase 1s and Phase 2s and make my own job of it or even just a side hustle. Small potatoes for large companies could be $1500 - $2000 in my pocket at the end of a couple weeks.
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
More than half my basement is finished and has glued down carpet. There's a sump pump available, but if power goes out, the sump doesn't run. If the sump float isn't angled correctly, the pump won't run. If the pump doesn't run, the groundwater levels rise and water starts seeping up through the concrete. We lost power in August and got about three inches of water that sat there for about five hours until the power came back on and the pump drained everything out. The remediation guys did a decent job and got everything back in order over the next week.
After that one, I went and got a backup battery system for the sump and then Ida hit us. This time the power didn't go out, but I had ran an extension cord from my neighbor who has a standby generator just in case along with double checking and testing the backup power system. I was watching the sump pit fill up and setup the float switch and everything, but the stupid thing didn't kick on when I was upstairs for a minute and we got half an inch of water and the carpet got soaked again. I ran back and turned it on manually after my kids told me about it, but there was just so much water that it took a while for the pump to drain everything fully. This time, I went and bought four box fans and another dehumidifier and did the cleanup myself after having seen the bill from the remediation company.
Things I've done since then:
-
Got a new float switch that has a better actuating mechanism that doesn't rely on the angle of the float bulb. It's strapped to the pipe and activates based on the exact water level in the sump. It works so much better as I'm watching it like a hawk this morning. It's been raining nonstop for like ten hours now.
-
Got a standby generator installed, so I no longer have to worry about power going out and the backup battery running down.
-
Built a lot of shelving in the unfinished part of the basement and I'm working through taking everything off the floor. Things like spare suitcases, old boxes, lumber, toy chests, etc.
-
I'm in the process of getting the dehumidifier setup to drain directly into the condensate drain next to the central AC unit, so it no longer drains into the sump pit. This will help with long term humidity levels in the basement.
-
Installed several downspout extensions around the house and in the process of getting all the gutters cleaned out. I've gone out with an umbrella during a major rain event and haven't seen any water flowing next to the found
I have been accepted into a MSc program where my project will be looking at stream temperatures across a watershed and how climate change has affected it using models. I'm on the fence whether I want to accept the offer or go into a bigger program (Earth Sciences) at UBC, SFU, or Waterloo. I haven't had any luck reaching out to professor's by email and need to give an answer for the project ASAP. I'd like to work in groundwater and remediation in the future, so although the stream temp project is super cool, I'm unsure if it will get me to where I want to be down the line. Any tips on finding MSc projects/supervisors and whether the type of project for a master's will heavily dictate the work you are qualified for in the future? TIA!

It's been a great stretch of news for BioLargo investors. On September 30, we got an update from the company in the form of a letter to shareholders (Sept 30 Letter to Shareholders) that outlined several new partnerships for commercial expansion across several divisions. Since then, good news has continued to roll in and the share price has started to respond accordingly. I've been a buyer since March 1, 2021 and plan on continuing to purchase as my ability to work overtime continues. I'm happy to see price increase, but see this as just a taste of what is to come.

It had limited rollout in consumer markets but was never pushed very hard. This has changed in a HUGE way. Ikigai Holdings approached BioLargo while seeking out a product to bring to market for pet odor elimination. They chose the CupriDyne product and are selling it under the name "Pooph".
