Caltha LLP, a Minnesota headquartered environmental assessment company, investigates the sources of contamination and follows through as needed to remediate them. Soil pollutants such as lead, cadmium, polycyclic aromatic hydrocarbons, arsenic, asbestos, and petroleum-related products can be found in urban and rural sites across Minnesota. As a result, parties that buy or sell commercial or industrial property in Minnesota are urged to complete an environmental site assessment as part of their due diligence and mitigate potential liability.

Minnesota Environmental Firm Performs Vapor Intrusion Assessments
A vapor intrusion screening and soil vapor sampling has become a crucial component of Phase I and Phase II environmental site assessments. Volatile organic compounds migrate through soil and groundwater and can potentially form harmful gases which can migrate into buildings, similar to radon gas. Soil vapor mitigation eliminates a key environmental liability and when needed is a component of our site remediation services.

Minnesota-based Consultant With MPCA, MDH, MDA and Local Agency Knowledge
Caltha LLP maintains close ties with the key State and local agencies that oversee waste management and contaminated site cleanup. In Minnesota, most environmental laws and regulations fall under the authority of the Minnesota Pollution Control Agency, although County governments can have additional regulations. The Minnesota Department of Health also plays an important role in reviewing and setting health-based cleanup goals used by MPCA. Many projects to investigate and cleanup contaminated sites are managed through two MPCA programs, the Voluntary Investigation & Cleanup (VIC) and Petroleum Brownfields Program (PBP)

The Minnesota Department of Agriculture (MDA) also has voluntary programs which effectively help farms and agrichemical businesses follow best practices to protect the environment. The MDA has a similar voluntary program to assess in the investigation and cleanup of agricultural chemical spills and leaks.
