Building Condition Inspections, Fungal Assessments Idaho and Oregon


Summit Environmental has performed inspections on hundreds of residential and commercial properties. Inspections include complete evaluations of most all building components including foundations, HVAC Systems, crawlspace, attic, framing, electrical, roofing, and plumbing. He completes a report for the inspection and works with realtors, potential buyers, and property owners to assist in real estate transactions and for more efficient and safe building operation. They have Certified Microbial Consultants and Certified Microbial Investigators and performs fungal assessments along with air and surface sampling and provides reports with findings and recommendations. 


Phase 1 and 2 Environmental Site Assessments

Involved in Hundreds of Phase 1, 2, and 3 Environmental Site Assessments, Remediations, and Closures.  Phase 1 assessment tasks include performing site visits to assess indications of past and present hazardous material handling, condition of the site, and to determine the presence of PCBs, asbestos, underground storage tanks, dry wells, hazardous air emissions, and other environmental liabilities.  Conducts interviews and record searches.  Phase 2 tasks include sampling soils, waste materials, ground water, wastewater, indoor and ambient air, transformers, building materials, and other site materials that may present an environmental risk. Assessments have been performed on small sites to sites of several acres and in remote areas.  Prepares project reports to document the findings and identify recommendations.

Microbial Assessments (Mold/Fungal/Bacterial)


Summit Environmental has performed hundreds of microbial property evaluations and has certified individuals by the American Indoor Air Quality Council.  Evaluations are consistent with the Standards of Practice for the Assessment of Indoor Environmental Quality and the IICRC S520 Standard for Professional Mold Remediation

Groundwater Studies and Remediation


Groundwater Remediation System Operation and Maintenance, Boise and Nampa, Idaho.  Serices include measurement of groundwater levels, sampling of groundwater from the monitoring and pumping wells, and evaluation and maintenance of an air stripper system, a state of the art pump and treat resin/carbon treatment system.  Summit performs monitoring well and pumping well operation and maintenance, and performs oversight during drilling operations.   When well production rates fall below acceptable levels, Summit Environmental personnel provides technical oversight during well redevelopment, which consists of surge block and chemical treatment.

Summit Environmental performs radon testing and mitigation.

Radon is a colorless, odorless, and tasteless radioactive gas that comes from the natural breakdown of uranium found in most rocks and soil.  Radon mixes with fresh air in the outdoors and is usually diluted to low levels, but inside an enclosed building, such as a home or school, radon can build up to high levels.  According to the Idaho Department of Health & Welfare’s Bureau of Environmental Health and Safety, dangerous radon levels have been found in every county in Idaho and in both new and old homes.  In addition, the Surgeon General has determined radon to be the number one cause of lung cancer in non-smokers and the second leading cause of lung cancer in the general population in the United States.


Testing is the only way to know how much radon may be in your home or building.  Two types of tests are available to measure radon:  short term which takes from 2 to 90 days, or long term which takes more than 90 days.  Because no level of radon is considered absolutely safe, radon levels should be reduced as much as possible.  The amount of radon that is within the Environmental Protection Agency’s (EPA) accepted level is 4 picoCuries per liter of air (pCi/L).


The EPA recommends fixing your home if the result of the one long-term or the average of two short-term tests exceeds the accepted level of 4 pCi/L.
