Recent Environmental Projects


Annual Environmental Reporting


Hygieneering recently assisted various clients with their annual environmental reporting needs. This included assistance in preparing and submitting Emergency Planning & Community Right to Know Act (EPCRA) Tier II Reports that were due March 1st.  Hygieneering is currently in the process of preparing and submitting Annual Illinois Air Emission Reports that are due May 1st and Emergency Planning & Community Right to Know Act (EPCRA) Toxic Release Inventory (TRI) Reports that are due July 1st for our clients.  Contact Hygieneering if you need assistance with your annual environmental reporting needs.

Construction Project with Lead Contaminated Soil


Hygieneering assisted our client that was tasked with conducting mechanical tasks in an area with soil heavily contaminated with lead. The project was outdoors in support of electrical substation maintenance. The lead soil was a hazardous waste and therefore dictated the project to be conducted in accordance with the OSHA HAZWOPER standard. Hygieneering assisted by preparing a Site Safety and Health Plan, lead training for workers, on-site management including worker and area air sampling for OSHA compliance and wipe samples to evaluate lead contamination transfer to surfaces outside the regulated zones.

The project was conducted over a several week period. The implementation of the Site Safety and Health Plan controlled potential worker and environmental contamination. The daily worker air samples, area air samples and wipe samples documented the effectiveness of the work practices and engineering controls used to control lead exposure.

Leaking Underground Storage Tank Abandonment in Place at Industrial Facility


Hygieneering was retained by one of our industrial clients for comprehensive consulting and services pertaining to the abandonment-in-place of a large heating oil underground storage tank (UST) and associated release of tank contents incident.  The purpose of this project was to ensure the proper abandonment of the tank system, provide environmental oversight, and prepare/provide proper UST closure documents, as required.  UST abandonment was conducted through the Chicago Department of Public Health (CDPH) permit process. Site-specific obstacles limited safe removal of the UST; therefore, an application for UST abandonment-in-place was submitted to the CDOE for review and approval. The project was conducted on a turnkey basis by Hygieneering.

Methane Gas Monitoring to Support Office Complex Constructed on Former Landfill

To support the ongoing engineering controls in place at an office complex constructed over a former landfill site, Hygieneering measured the methane gas concentrations at the facility.  Hygieneering conducted air monitoring at numerous locations outside the building at landfill gas release points (designed engineering control locations), around the building foundation and within the building.  Results were used to document the landfill gas engineering control systems were effective in keeping landfill gasses out of the office buildings on campus.  Hygieneering collected direct read measurements using a Thermo TVA 2020 flame ionization detector (FID). 


Property Line Nuisance Dust Assessment


Our client, a mining operation, desired to collect data of property line nuisance dust on worst-case days during the dry, hot summer days.


Hygieneering prepared and implemented an air sampling program.  Airborne dust concentrations were measured and data logged around the perimeter of the site throughout the day and night using 3 TSI DustTrak DRX instruments (Photo 1 shows representative set-up). The DustTrak DRX units provide real-time dust monitoring that simultaneously measures both mass and size fraction.  The DustTrak DRX monitor uses light-scattering laser photometers that provide real-time aerosol mass readings and data logs.  The instruments subdivided the concentration of dust by particle size with the following breakdown: total, PM10, respirable, PM2.5 and PM1.  Example sampling location data is presented in the table and graphs provided for reference.


In summary, ambient fence-line air sampling data with associated environmental conditions and site operational activities was provided to our client which gave them compliance insight and documentation.

Boiler Stack Demolition and UST Removal


To assist one of our school district clients with ongoing renovation/construction issues, Hygieneering provided technical project design and management of the demolition of a large boiler stack and removal of 2 underground storage tanks.  Our services included the initial inspection of the stack for asbestos containing materials and other potentially hazardous materials.  Based on this information, a turnkey project design was developed including environmental and safety issues for the demolition of the stack.  There was also 2 underground storage tanks in the area that needed to be removed following the stack removal.  Hygieneering’s daily management of the site included:   

  • Prior to the start of work, a Site Safety Plan reviewed with all workers.

  • Donning of proper personal protective equipment (PPE) including safety shoes, safety glasses, hardhat, high visibility vests, personal dust masks, harness and lanyard was enforced.

  • Review of the shift plans and associated hazards such as elevated work, pressurized gas line, proper lifting, safe use of air operated chipping hammers, and gas operated saws.

  • Shift inspections were conducted of lifts, harnesses, tools and excavation equipment.


The end result was the stack was demolished and tanks removed and all associated materials were recycled or disposed of properly in accordance with environmental regulations.  The site was turned over as a clean location of the client to commence desired building addition.

Adaptive Reuse Project


For over 25 years, Hygieneering has been assisting our clients effectively manage their environmental issues.  We are currently working with client on an Adaptive Reuse type project that will take an abandoned, environmentally contaminated old laboratory/office complex and turn it into an aesthetic recreational Green Space in Chicago. 


Hygieneering conducted numerous environmental services along a range of our technical disciplines in this Adaptive Reuse Project effort. 


  • Phase I & Phase II Environmental Site Assessments

  • Facility Pre-demolition Survey for Asbestos, Lead Paint, Mercury, and other hazardous materials

  • Comprehensive design and management of remediation efforts

  • Specialty assessment and turnkey remediation services for perchloric acid lab hood contamination

  • Underground storage tank and associated Fuel Oil Line removal

  • Indoor air quality monitoring and management during demolition activities


Our services are always designed to manage client risk and regulatory compliance, while reducing costs and at the same time protecting the health of workers and the public and impacts on the environment.

Drinking Water Testing


Due to the recent press of elevated levels of lead in drinking water in Flint Michigan and other cities, many commercial office, multi-tenant residential and school districts have tested the drinking water in their facilities.  Hygieneering has recently conducted drinking water testing for lead and other parameters at numerous facilities.


Have you ever wondered about the quality of your drinking water? The US Environmental Protection Agency’s Safe Drinking Water Act (SDWA) established health and safety standards for public water systems. The EPA regulates various contaminants in public drinking water supplies by establishing maximum contaminant levels, which are the highest level of a contaminant that is allowed in drinking water, via the National Primary Drinking Water Regulations, also known as Primary Standards. The EPA also established the National Secondary Drinking Water Regulations, also known as Secondary Standards, which are non-enforceable guidelines regulating contaminants that may cause cosmetic effects (skin or tooth discoloration), aesthetic effects (undesirable taste, odor, or color), and technical effects (damage to water equipment or reduced effectiveness of treatment for other contaminants) in drinking water.


Hygieneering offers technical guidance for regulated and unregulated contaminants found in drinking water. Hygieneering provides drinking water quality testing services and comparative analysis to EPA’s Primary and Secondary Drinking Water Standards. Contact us for further information on how we can assist with your water quality needs.
