Thanks for your reply. The site was a restaurant/bar, so I'm thinking maybe cleaning chemicals or oils/grease? There are also underground wastewater tanks (the site is in the Florida Keys). I'm thinking of not listing it as a REC since I have no reason to believe there was a release, but instead listing it as an additional consideration and letting the client decide if he wants to do further testing. What do you think?
This may just be a terminology issue, but a septic tank is not supposed to "leak". It's commonly known that a septic tank is a solid bottom structure. The septic tank should be connected to a leaching pool, which is supposed to discharge to the subsurface. Consider historical/current site operations to determine whether these may likely conducted discharges that may impact the property.
If it was used by a residential home on a farm, then probably not. If it was attached to a 40 year old industrial building in Nassau County, NY, then probably yes. Big grey area in between those two, but typically comes down to the question of how likely was it that hazardous wastes were disposed of to the cesspit.
Also, even if it's not identified as a REC, further evaluation may be warranted for your client. For example, if they are going to be building homes on the property there may be a higher level of care required than is provided by an ASTM E1527 REC determination.
what about a cesspool/cesspit - would that be a REC? I have no idea what the condition of the tank is as it has been abandoned (crushed and filled in).
Ha! I was about to mark your post as inappropriate but I see it is actually very PG. No need for alarm, commonground. I assure you the attachment is safe for work. :)
Don't mess around on this one, if it's in Silicon Valley you better know what you are doing. If it's in Orange County, it's time to start thinking about moving, it's way too crowded and it's a top county in the US with members on Ashley Madison.
From photo, looks more like the concrete was etched by acid or worn way by abrasion. Auto body shops sometimes do acid washing. I doubt you'll find anything, but let us know how it turns out.
Thanks for responding, this is still an unresolved issue at this site. No, I do not think asphalt made its way into the sample. Unless the client proceeds with additional sampling, I may never know if there is another source.
Don't guess, check with the regulatory agencies that may have files related to hazardous materials and hazardous waste....City/County Health/Fire, Air District, Sanitation, etc. If there was mfg being conducted and large volumes of haz mats were used, some older records may exist related to these operations. If you don't uncover something specific to document haz mat usage, I too would not consider this a REC.
Thanks for the reply. This is for the subject property (not a business nearby) and it's not listed on any databases. All I know about the former facility is from an internet search which said computer storage manufacturer and tape library manufacturer.
If you're talking about magnetic tape and/or other mag media manufacture, the primary solvents used were acetone, MEK, MIBK and cyclohexanone. But it's not clear from your description whether the listed property contained this kind of product, or hard drives, or something else entirely. In any event, if the use of solvents were significant, I'd expect a RCRA generator listing would show up.
I'm assuming this facility doesn't show up on the database listing, correct? If that's the case, assuming the listing is not for your subject Property but instead something close by, I wouldn't spend any more time thinking about it: not a REC.
Isopropyl alcohol, freon, TCE/PCE, and xylene would probably be good place to start.
Thanks Matt, yes, the pattern is now especially clear = 10 or so buildings were built on top of former waste disposal ponds.
You should be a science fiction writer... "Developer that owns the land hears that the airport will have a lot of excess material when they expand runway. Developer tells airport, hey that's great, go ahead and put it on my property and I can use the material for the industrial park I'm in the process of developing in that area."
What a vivid imagination....
Here, I found it, call (408) 765-8080 and ask for Andy Grove, he's a real good guy.
Try Andy Grove, he may know something, search the internet for his phone number, if you can't find it let me know and I will look in my old address books.
