BREAKING: Private lab withheld from MassDEP data of elevated levels of the carcinogen 1,3-butadiene it found in #Weymouth last year. On the left, lab's original samples from summer '18; on the right, amended report it *suddenly* produced last night, showing 1,3-butadeine.
The amended report's newly discovered data shows 1,3-butadiene levels *above* the state's AAL -- the allowable limit for cancer risk, which is extremely low limit of exposure because 1,3-butadiene is a highly potent compound, consistently associated with leukemia.
Here's another compound the private lab *suddenly* discovered last night, but didn't disclose last summer: Chloromethane. On the left, the original report; on the right, the newly discovered one with chloromethane. EPA classifies chloromethane as a possible carcinogen.
Here's yet another compound *suddenly* discovered this week by the lab, even though it had the data of its presence in #Weymouth back in August 2018: 1,2,4-trimethylbenzene, a toxin associated with respiratory problems. cdc.gov/niosh/npg/npgd…
And here's another toxin, which suddenly appears in the amended report the lab submitted last night -- even though it was detected back in *August 2018*: Freon-113.
And here's another toxin, detected by DEP's lab in *August '18* but reported only last night: n-hexane.
And here's another one: Trichlorofluoromethane. Again, this is a compound detected in *August '18* by the private lab DEP contracted with -- but only reported yesterday.
And here's another one, detected in August last year but reported only last night: Vinyl acetate, which is a possible carcinogen: toxnet.nlm.nih.gov/cgi-bin/sis/se…
Here's another one: A July 2018 sample air canister in the Fore River Basin detected *elevated* levels of the potent carcinogen 1,3-butadiene. The original report (left) sent to the DEP did *not* include it. The amended report (right) sent last night did.
The HIA report concluded that amongst the Tentatively Identified Compounds (TICS) the private lab found, only methanol was above state limits (and not 1,3-butadiene). But now the new data shows 1,3-butadiene was *also* above those levels
And here's another canister, where carcinogen 1,3-butadiene was detected in elevated levels (above state limits) back in July 2018 but reported only *this week*. On the left, from the original report; on the right, the suddenly discovered one, with the 1,3-butadiene.
As far as I can tell, the new report submitted by the private lab to the @MassDEP this week shows that the carcinogen 1,3-butadiene was present in THREE different sample canisters. A reminder: these data were produced last summer but for some reason sent to the DEP only this week
And here's another one: Tetrahydrofuran. This compound, which research shows may be carcinogenic to humans based on animal studies, was detected by the private lab last last summer but reported only this week.
