What is the average level of carbon monoxide in homes?
Levels in Homes Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher. Steps to Reduce Exposure to Carbon Monoxide…

What are combustion products?
Combustion pollutants found indoors include: outdoor air, tobacco smoke, exhaust from car and lawn mower internal combustion engines, and some hobby activities such as welding, woodburning, and soldering. Combustion pollutants can also come from vented or unvented combustion appliances. These appliances include space heaters, gas ranges and ovens, furnaces, gas…

What will the BASE data tell me about my particular building?
The BASE study was not designed to give specific information on any individual building or to produce the type of diagnostic data needed to evaluate the nature, validity, or cause of IAQ complaints. See also associated question, What is the Building Assessment Survey and Evaluation Study (BASE) at: www.epa.gov/indoor-air-quality-iaq/what-building-assessment-survey-and-evaluation-study-base…

How can I connect with other tribal IAQ leaders?
EPA's Tribal IAQ Website is a great resource to network with other leaders throughout the country. Visit the Directory of Tribal Indoor Air Quality Champions to read about the issues other tribes are facing and to obtain their contact information. Also, consider listing yourself in the directory. Send an e-mail…

Will boiling my water help?
No. Boiling water will NOT reduce nitrate levels. In fact, it will make the level of nitrate worse because some of the water will evaporate but the nitrate will not. This increases the concentration of nitrate in water.

Does EPA have any data or test results on Norwood School to discuss?
EPA has not collected any samples at the school, therefore there is no data to share or discuss.

What was the sampling methodology, or the criteria used, to select the residential properties to be sampled?
All properties in Winona Homes were selected for potential sampling based on the complaint EPA received in August 2016 which alleged that soil used to grade the land for construction of the homes may have come from a contaminated source and may be a contributing environmental factor affecting the health…

If EPA determined there is enough contamination in the creek and wetland to warrant further aquatic studies for fish and turtles, why would this not be a health concern for children and adults who swim or fish in the creeks?
Surface water and sediment data from Muckinipattis and Darby Creek were compared to EPA’s human health screening levels and all contaminants were below screening. Aquatic organisms show adverse effects from exposure to contaminants more readily than humans because these organisms have 24-hour direct contact with contaminated media (soil, surface water…

What does it mean if I live in an area with “chlordane” and it is a “red” area?
The “red” area on your sampling results table likely means that there is three times the amount of chlordane found here compared to the background sampling data. This result likely reflects historic pesticide application to a home. Chlordane can be found in soil more than 20-30 years after pesticide application.

Can Norwood residents safely garden and eat produce from these gardens - or could the soils be contaminated? Sometimes we dig down into the soil a few feet to plant our vegetables is that OK to do and can we eat vegetables if we dug down this deep?
It is safe to play, garden and grow fruits and vegetables in your yard. Please keep in mind, current research recommends hand washing after play or contact with urban soils where concentrations of contaminants maybe higher than soils in rural areas. In addition, all fruits and vegetables should be thoroughly…

Did EPA dig down deep enough in all the residential properties tested to ensure that people with basements that routinely flood were adequately tested? For example, did EPA test below 12 feet deep in homes where basements are 12-14 feet below ground level and where flooding regularly occurs? Some people routinely get water in their basements and many residential properties have “French drains.” Also did EPA test to see if any water found in residential basement areas was contaminated?
EPA advanced soil borings as deep as 10 feet below ground surface, which is deep enough to reach the average depth of basement foundations. EPA did not test soil at depths greater than 10-feet, as there is a very low likelihood that persons will come into contact with soil at…

What is the difference between parameter codes 88101 and 88502 for PM2.5 monitors?
The 88101 monitors include both manually operated Federal Reference Methods (FRMs) and automated Federal Equivalent Methods (FEMs) and each are used for determining compliance with the PM2.5 standards. The 88502 monitors are “FRM-like” but are not used for regulatory purposes. Both 88101 and 88502 monitors are used for reporting daily…

What about people who work in their yards regularly - are they at risk?
It is safe to play, garden, and grow fruits and vegetables in your yard. Please keep in mind, current research recommends hand washing after play or contact with urban soils where concentrations of contaminants maybe higher than soils in rural areas. In addition, all fruits and vegetables should be thoroughly…
