Erler & Kalinowski, Inc. (EKI) services

EKI has completed investigation and remediation studies for a variety of contaminated sites.  We have prepared EE/CA, RI, and FS reports, QAPPs, and treatability study work plans for federal Superfund sites that are consistent with CERCLA.  EKI has assisted at RCRA facilities where hazardous waste releases have occurred by performing the RFA, RFI, interim actions, CMS, and CMI, as warranted.  In addition to our CERCLA and RCRA experience, we have helped clients with performing investigation and remediation studies necessary to satisfy state-specific and local requirements.  EKI has prepared RAPs for DTSC that comply with Section 25356.1 of Chapter 6.8 of the California Health and Safety Code and has assessed environmental conditions or achieved closure for sites in Texas under TRRP, in Massachusetts under MCP, in New Jersey under ISRA, in Louisiana under RECAP, in Maine under VRAP, and in Illinois under TACO.

Obtaining insight on how contaminants change and move in the environment may be important in distinguishing the party responsible for a release, judging if a significant potential for chemical exposure exists, or determining appropriate remedial actions.  EKI is accomplished in fate and transport modeling of contaminants in the vadose zone, groundwater, surface water, and atmosphere.  We have conducted vapor intrusion to indoor air analyses, performed natural attenuation evaluations of chlorinated solvents, petroleum hydrocarbons, hexavalent chromium, pesticides, and other contaminants, and completed groundwater flow simulations ranging from the use of simple analytical equations to numerical computer codes such as MODFLOW.

EKI conducts human health and ecological risk assessments in support of remedial actions designed to achieve regulatory agency closure of releases or to facilitate redevelopment of brownfields properties.  A defensible risk assessment requires an understanding of the chemical distribution in environmental media, definition of the reasonably anticipated land uses, and estimation of potential chemical exposures.  Based upon this knowledge, it can be determined if the risk at a site can be judged by simply comparing chemical data to published screening levels, such as EPA PRGs or state criteria, or whether the risk and site-specific remediation goals must be calculated following EPA RAGs or state guidance.  EKI has applied various risk-based corrective action methods to address the issues posed by site contamination.

EKI provides consulting services related to the assessment and mitigation of vapor intrusion. We have developed conceptual site models and performed site investigations using approaches ranging from shallow soil vapor surveys to multi-depth wells to investigate deep vadose zones, as well as the collection of sub-slab vapor and indoor air samples in commercial and residential buildings. We have conducted assessments of potential for vapor intrusion and performance of human health risk assessments, performed mitigation system pilot tests and diagnostic testing, and planned, design, and prepared drawings and specifications for vapor intrusion mitigation systems to retrofit existing commercial and residential properties and for vapor intrusion mitigation systems at new buildings.
