TCE soil vapor intrusion fears in Como

Soil vapor intrusion allows contaminants
to enter homes and businesses.

Minnesota health and pollution officials are holding community forums to discuss efforts to discuss efforts to handle TCE, a degreasing solvent that may be invading homes in the Como area of southeast Minneapolis.

TCE, which stands for trichloroethylene, had been dumped from 1947 to 1962 in a pit behind a now-defunct General Mills plant.

The state is asking some 200 property owners near Van Cleve Park to allow testing in their basements to determine whether TCE vapors in the soil below their foundations are finding a way into their homes.

Prolonged, substantial exposure to TCE has been linked to certain cancers such as non-Hodgkin’s lymphoma as well as birth defects.

While there is no evidence that cancer or other health problems are more prevalent in the neighborhood, state officials said they are acting out of caution as science has revealed more about the way TCE can evaporate from groundwater and rise through soils.

The neighborhood’s TCE problem has been known since the early 1980s, when the old General Mills property at 2010 E. Hennepin Av. was declared a federal Superfund cleanup site.

General Mills agreed to pay for the pumping and treatment of groundwater to remove traces of the chemical.

Groundwater treatment continued until 2010, when the Minnesota Pollution Control Agency declared it was safe to halt the cleanup — but monitoring since that time found TCE in the soil gas below the surface.

Forty tests were conducted on the soil under sidewalks and streets in a wide section of the Como neighborhood near the old General Mills site. Thirteen sites showed TCE rates above residential air safety standards, allowing health officials to pinpoint a 16-block area trailing southwest from the plant to Van Cleve.


Tests and remedies

General Mills has agreed to arrange and pay for testing for TCE, at a cost of about $1,000 per property, as well as the $2,000-per-property cost of fixing homes or businesses if TCE is found. In most cases, the solution will be a ventilation system similar to the ones used in homes to remove radon.

The company previously paid to remove contaminated soil from the site of its former food and chemical research plant, which has since been sold and redeveloped into small-business offices.

To assess any potential health problems, the Health Department has reviewed data from its registries of all birth defects and cancer cases in the state. The 55414 ZIP code, which includes the Como neighborhood, does not have a higher rate of birth defects.

A review of the cancer database is ongoing.

Home health care workers get recognition

OT, minimum wage extended to health care workers

New rules for home health care workers
may limit access for some families.

The Obama administration approved rules that extend minimum wage and overtime pay to nearly 2 million home health care workers who help the elderly and disabled with everyday tasks such as bathing, eating or taking medicine, according to an AP report.

Home care aides have been exempt from federal wage laws since 1974, when they were placed in the same category as neighborhood baby sitters. But their ranks have surged with the aging population and the field is now one of the fastest-growing professions.

Labor unions and worker advocacy groups have been seeking the change for years, arguing that nearly half of caregivers live at or below the poverty level or receive public benefits such as food stamps and Medicaid.

But some health care companies claim new overtime requirements will make it tougher for families to afford home care for their aging parents. Lobbyists for the $84 billion industry argue the new requirements could reduce the quality of care and even lower the take-home pay of caregivers if companies decide not to send workers out for shifts longer than eight hours.

The new rules will take effect in January 2015, which will give time for states and industry providers to adjust to the new requirements. New wage and hour rules typically take effect within 60 days after final approval. The rules cover home health aides, personal care aides and certified nursing assistants that provide care to the elderly and people with injuries, illnesses and disabilities.

President Barack Obama first proposed the rules nearly two years ago as part of broader effort to boost the economy and help low-income workers struggling to make ends meet. More than 90 percent of home care aides are women. About 30 percent are black, and 12 percent are Hispanic.

Experts estimated that by 2020, the country would need about 4 million home care aides to meet the needs of its graying population. The number of Americans over 65 is expected to nearly double over the next 20 years.

Fifteen states already extend state minimum wage and overtime protections to home care workers, and another six states and Washington, D.C., mandate state minimum wage protections.

The current median pay for home care workers is about $9.70 per hour, higher than the federal minimum wage of $7.25 an hour, according to Labor Department figures. But overtime pay could help lift wages substantially for those who work more than 40 hours a week.

The new rules will continue to exempt from minimum wage and overtime requirements those workers who mainly visit the elderly to provide company or engage in hobbies and are employed directly by the person or family receiving services.

Adjust IAQ in home care situations

Illness and disease can lead to bad odors and poor indoor air quality. Opening windows regularly helps but is not always feasible.

For better indoor air quality and healthier air, home health care aides can use portable and reliable indoor air cleaners with the right types of filters.

The air cleaners need activated carbon, HEPA and UV germicidal filtration to remove airborne contaminants such as bacteria, viruses, odors, chemicals, particles and mold.

Majority of builders see green home trend growing

The green trend is continuing in the construction industry
and indoor air quality is becoming more important.

More than 80% of builders surveyed in a new report say that construction now is greener than just two years ago and that energy-efficient features are more prevalent in new homes.

The goal to save money on utility bills may drive a lot of those energy-efficient choices, as does the need to differentiate a home from the competition.

Green homes also gained popularity because they are seen as being higher quality (and therefore higher value) and providing better indoor air quality.

Speaking of indoor air quality - it is growing in importance and focus for home builders. 60% of home builders believe that efforts to improve indoor air quality make homes greener than they were two years ago, and 95% of high volume home builders report including features that impact air quality.

Green homes made up a 17% share in the construction market in 2011, which amounts to $17 billion, but the report estimates that this market share will increase to between 29% and 38% by the year 2016.

A growing number of projects are also seeking green certification, the report says, and higher first costs for building green are noted by a much lower percentage of builders as an obstacle now than they were reported in 2008.

The SmartMarket report was released by McGraw-Hill Construction and surveyed members of the National Association of Home Builders.

Taking care of indoor air quality

When the energy-saving wave first hit the construction and renovation market, it was driven by a desire to save on heating costs and utility bills.

However, the ensuing airtight houses gave rise to a new risk to public health – indoor air pollution, which was named as one of the top 5 risks to public health by health authorities like the EPA.

Electrocorp offers portable
air cleaners like the RAP series.

So it’s good to hear that indoor air quality has been growing in importance in the building industry.

Electrocorp has been a long-time promoter of good indoor air quality and offers air cleaners for commercial and industrial applications that can remove the widest range of indoor air pollutants.

Electrocorp’s air cleaners contain a multistage filtration system with activated carbon + HEPA + optional UV germicidal filtration.

Together, these filters can remove airborne chemicals, gases, odors, particles, dust, bacteria, viruses, mold and other contaminants.

Whether it’s during construction or renovation work, remediation projects or for air cleaning after the work is done in single-family dwellings or larger settings, Electrocorp can provide the right air cleaners, the most effective air filters and the most customizable options.
