WV TAP

An independent research team hired by Gov. Tomblin to further study the chemical that contaminated the water supply of 300,00 West Virginians in January released their final report Thursday.

The West Virginia Testing Assessment Project, or WVTAP, began studying MCHM in February and has released results along the way. Thursday’s report includes their previously released findings and recommendations for moving forward.

An independent research group suggests sampling water in 720 West Virginia homes for a chemical that spilled into the water supply in January.

Researchers from the West Virginia Testing Assessment Project, or WV TAP, say that number of homes would be "statistically defensible" in determining whether affected households are chemical-free.

The group sampled 10 homes in February for crude MCHM using state taxpayer dollars. Each contained chemical traces, but the concentrations were about 675 times weaker than what federal officials call safe to drink. The report says levels of the chemical have continued to decline since the spill.

Taking into consideration dermal and inhalation exposures, as well as ingestion, WV TAP researchers offer a screening level for MCHM eight times as stringent as the CDC's--still yet, they say levels of the chemical in the water below the federal agency's screening level is "safe."

Independent researchers working together on the taxpayer-funded WV TAP project have already released an expert odor analysis for Crude MCHM, and have delivered the findings of their 10 home testing pilot project. However, the public has repeatedly called for an understanding of potential health effects from the January spill of Crude MCHM by Freedom Industries.

A group of independent researchers has found that the chemical crude MCHM is still present in some West Virginia homes. That's the coal-cleaning chemical that spilled into the Elk River back in January out of a storage tank operated by the company Freedom Industries. The spill contaminated drinking water for hundreds of thousands of people. The research group was formed by West Virginia's governor after public pressure.

Dave Mistich of West Virginia Public Broadcasting reports on the research group's latest findings.

Taxpayer-funded researchers say the 10 West Virginia homes they tested each contained traces of a chemical that spilled into their water supply in January.
 
In samples taken Feb. 11-18, chemical remnants were generally about 675 times less concentrated than the federal safe drinking level for the chemical in water. The independent WV TAP group discussed results Friday at West Virginia State University.

A Virginia Tech study says a chemical that spilled into 300,000 West Virginians' water supply in January stops smelling at a level 47 times stronger than other researchers found.
 
The group that discovered the lower chemical odor level questioned the Virginia Tech team's methods.
 
The Virginia Tech group said in a news release that it detected the chemical in the air with specialized instruments. It used a gas law to calculate the corresponding odor threshold in water.
 

Independent researchers involved in testing, odor analysis, and health effects studies on Crude MCHM answered questions Tuesday about their work and what that means going forward.

Researchers involved in a taxpayer-funded, independent water testing project in response to the January 9 spill by Freedom Industries began releasing findings earlier this week. The project, known as WV TAP, is currently attempting to determine the odor threshold for the chemical in question—crude MCHM. They are also investigating the safety factors applied by the CDC in determining how much chemical can be in water and still be called safe to drink.

Dr. Michael McGuire is conducting odor analysis panels to determine at what levels Crude MCHM can be smelled in the water. Results released Monday from an expert panel conducted by McGuire put that number at 0.15 parts per billion (ppb).

Researchers took time Tuesday to answer questions about the first round of studies that have been released.

Researchers involved in the independent, taxpayer-funded testing project known as WV TAP say results from a single expert panel show that Crude MCHM can be detected by an expert human nose when analytical methods used in testing the water indicate non-detect levels.

The two scientists leading the West Virginia Testing Assessment Project, or WV TAP, following the Jan. 9 chemical spill into the Elk River near Charleston provided an update on the project Friday. The briefing was held in a Department of Health and Human Resources conference room in downtown Charleston.

Dr. Andrew Whelton and Jeffrey Rosen spoke to reporters and said they have completed gathering samples of 10 homes across the area affected. Samples from both hot and cold water were taken.
