This was the first thing that greeted cobysdad and myself last night when we launched from aarons creek. There is a brand new warning sign posted at the bottom of the rock ramp that states DO NOT EAT THE FISH and it gives a list of all species with PCB's and so on...the only fish i didnt see on the list was crappie (i believe).......Any one got any info on this or know if it is a lake wide thing?????
Theres been something polluting the water for years and I guess theres not many places that the fish are not contaminated in some way or the other,from all the lakes and rivers right into the ocean as well.
Here on Kerr and the tributary rivers, its mostly about Mercury & PCB's coming from generally unknown sources (once a source is known it gets attention.) What fish gets onto the adisory and where is related to sampling activities...DEQ does actually take samples and analyze the fish. One BIG thing to watch here is that if a species wasn't in the sample...say DIF tried 3-4 times in a section of water and did not come up with any hairy-legged-red-breasted punkfish, then hairy-legged-red-breasted punkfish would have no consumption advisory...that they are not on the advisory in other words does not "clear" the fish, it just says that they were not sampled and/or found to have sufficient level for a warning.
Related to the crappies, this was news to me when you posted. I would not be surprized about any mercury/PCB warning above the split but in AArons I'd not seen that so I went off to the polluters database to check. The result I found is that Aarons has contamination from fecal coliform and is classified as "impaired" for recreation. Many of the tribs have this posting, its not new or unusual. I did not find any consumption advisories against Aarons and Aarons is not included on the larger advisory so I shipped a note over to contact in DEQ to find out what's up...jfo
DEQ quickly got back to me already and confirmed that most of Aarons is not covered by the Mercury/PCB advisories. Where Aarons joins into the Dan's downstream flow its in the advisory but upstream should be covered by the FC warning which is only against recreation, not consumption. 60lb club or coby dad or other....where exactly was the sign? If it was at Holiday Shores/Gravel Ridge it'd be appropriate but if it was there by 58 on Aarons, DEQ will look into if its correctly placed or not...let me know...jfo
the sign was posted at the bottom of the boat ramp there at aarons creek....right on the left hand side next to the water.........looks like there used to be a old sign there but now there is a brand new one.....it must have been put up over the past week, because we always launch from there and never seen it before..........but yes the sign is next to the 58 bridge there at the ramp.........
I work with a company that builds houses. When we complete a new house, we have to chlorinate the well and then have the municipality (or in some cases a private laboratory) test a water sample to make sure the well water is OK to drink. The first bacteria they check for is fecal coliform (F-Coli). If and when it's present, they immediately check for "E-Coli". They tell me that the presence of F-Coli determines that the environment is conducive to the growth of many other types of harmful bacteria. But, that the F-Coli itself is basically harmless. I asked one of those water quality scientists one time. "If I ate a whole quart jar full of F-Coli, what would happen to me?" He said "If you had a real sensitive system you might get an upset stomach". The F-Coli itself is nothing to fear, it's the other types of bacteria that could possibly follow that are deadly.
You are right about F-Coli . . . not desirable because it can weaken other natural imunities but certainly nothing to worry about as long as you are reasonably fit and healthy. Dioxins on the other hand have serious implications as do PCB's. There has been a great deal of work on this worldwide and the conclusions aren't encouraging. Where do you guys think these pollutants are coming from ?

PCB's were used in electric transformers to help keep them cool. It has been banned now but anywhere there are old electrial substations the soil is contaminated with PCB and leaches into the water. There were other products that contained see the list below Transformers and capacitors Other electrical equipment including voltage regulators, switches, reclosers, bushings, and electromagnets Oil used in motors and hydraulic systems Old electrical devices or appliances containing PCB capacitors Fluorescent light ballasts Cable insulation Thermal insulation material including fiberglass, felt, foam, and cork Adhesives and tapes Oil-based paint Caulking Plastics Carbonless copy paper This substance is now banned in the US but there is a lot of residue from these products in the environment. Dioxin can be formed by burning wood and is a problem in streams after forest fires see web link. www.niehs.nih.gov/health/topics/agents/dioxins/index.cfm - 12k -
OK, had several go-rounds with DEQ mostly for my clarity...here's the deal (for now):
- Aarons creek is not under the PCB/Mercury Consumption advisory except in the downstream areas at the confluence to the Dan where the advisory on the Dan/Hyco would "backwash" into the mouth of Aarons or where the waters are common. To follow onto assasains comment above, and having been around this DEQ stuff now a bit I can say that when a point source is ID'd its attacked (good thing). But one of those parts he mentions may have been in the river in the mud for 30 years, then a wash comes down and refloats it spilling its mercury/PCB's into the water (recontamination). Generally these toxins do settle and so when you get more downstream into the reservoir...generally the consumptions advisories lift because the churn is less therefore the fish intake less.
- The Fecal Coliform impairment in Aarons is surely valid and inforce but is not against consumption, its a warning towards recreation. As implied above, there is an ambient level of fecal coliform that can be present and the water not be considered "impaired". Aarons does exceed that level therefore gets the tag for recreation.
DEQ isn't responsible for posting the signs (DIF is) and DEQ is thinking maybe the DIF posted that sign there as they knew many putting in there would be downstream in the affected areas. I think it could be that or a simple mistake; the mistake being that Buffalo, Hyco, Bluestone, Dan & Staunton all have the consumption advisory...easy mistake to make.
Since its better safe than sorry IMHO...I'd likely let the sign stay even though technically that's a clean spot relative to the consumption advisory. 60lb, the list of the fish species is listed on that link I put above...I misread your post that crappies were on it but neither you nor the advisory said that...the crappies are generally very clean fish. btw, if you scroll down the advisory to the section on Kerr lake there are additional species in the reservoir. Hey folks, have great day...jfo
yea i stated that the crappie were not on the list....and the sign didnt say anything about recreation warning...it clearly stated do not eat these fish and it gave a list of fish and lengths.... so here is one for everyone to think about......those idiots that are limblining up the river all year and selling these huge flatheads are doing nothing more than harming innocent human beings.......way to go fellas you should get a rubber cookie for that one......idiots.
