A Positive Result on Multiple Levels!

Every building is required to submit an XRF report to demonstrate the absence of hazardous lead on the property. In one instance, our client experienced an XRF trigger on a wall that was actually free of lead contamination.

Through our comprehensive assessment process, which involves reviewing leases, construction dates, and other variables, the MHE team successfully obtained a Certificate of Occupancy issued after 1960. This conclusive evidence verified that our client’s apartments were free from lead contamination.

In addition, our close collaboration with the lead office allowed us to implement a unique lead detection method using paint chips in collaboration with XRF testing to contest violations. This innovative approach has proven effective in eliminating violations.
