As a part of its ongoing growth efforts, and to build upon its existing operation in Southeast Wisconsin, Suburban Laboratories is pleased to announce it has acquired the field services, sampling and laboratory testing assets of Cardinal Environmental, Inc. of Sheboygan, WI, effective February 1, 2021.

All the Cardinal analytical, field and client service team members will join Suburban. This reflects the desire of both companies to continue to provide essential services to existing clients and expand opportunities to serve new clients across the State of Wisconsin.

“I am thrilled to welcome the Cardinal group to Suburban,” said Jarrett Thomas, Suburban Laboratories’ president. “We offer complementary services and shared values in our focus on the needs of our clients.  “We look forward to offering a more complete package of services to current and future clients throughout the State of Wisconsin.”

“Jarrett and I have known each other for many years and we’ve always had a strong relationship,” says Cardinal Environmental president Scott Hanson. “As I explored opportunities for my business as I prepared to retire, I felt that Suburban would be a great partner for our clients, employees and communities.”

Highlights of the combination include:

  • Personalized service. Cardinal and Suburban are culturally aligned on the importance of responsive client service and how important it is to nurture relationships.
  • Expanded geographic convenience. With locations in Sheboygan and Mukwonago, as well as expanded courier route options, more convenient logistics will be available to clients throughout Wisconsin.

We Remain Open During Stay-at-Home Mandate

The Governor of Illinois has just issued a “stay at home” order essentially closing all “non-essential” businesses.  As of 3:35 PM on 3/20/20, Illinois has not defined what is an essential business.  As a public health laboratory, Suburban Laboratories should be considered an essential business as other states with similar mandates have determined.  Until we hear otherwise, Suburban Laboratories will remain open to serve our customers.
We will be monitoring the situation closely and if anything changes, we will notify clients via email and via our website.  If you have any questions, contact your project manager or me.

Response to COVID-19 Pandemic

Dear Employees and Customers,

Nothing is more important than the health and safety of our employees and customers.  At Suburban Laboratories, we are closely monitoring the spread of the coronavirus COVID-19.  Our company intends to remain open during this crisis.  As a part of our general laboratory safety protocols and aseptic laboratory practices, we already have many policies and procedures in place to minimize contamination.  Those practices, including use of sterile gloves, personal protective equipment, disinfection procedures and our laboratory grade ventilation system also helps prevention of contamination and spread of COVID-19.

As a precaution, Suburban Laboratories is advising any employee that comes down with flu-like symptoms to stay home from work until it can be determined that they are not COVID-19 positive.  Should an individual that has been in our facilities test positive or have been in contact with someone that has tested positive with COVID-19, additional cleaning and disinfecting procedures will be taken.

Although this virus is something that should not be taken lightly, simple precautions like washing your hands regularly with soap and hot water for at least 20 seconds and practicing “social distancing” approaches have been proven to combat the virus.

We will issue any updates to our policies via our website.  If you have any further questions about COVID-19 please refer to the CDC website or reach out to me.

Best Regards,

Suburban Laboratories, Inc.

Jarrett Thomas

New IL Construction Sample Analysis Requirements

The Illinois EPA adopted new public water supply rules on July 25, 2019 that include modifications to analysis and reporting of new construction bacterial samples.  Under the new rules, new construction samples must be reported as presence or absence of total coliform bacteria.  This is a change from previous reporting requirements of no bacterial growth as measured by the membrane filtration method per Standard Methods 9222B.  This change allows laboratories to adopt current presence/absence methods utilized for the analysis of routine compliance distribution samples for total coliform and e. coli.  While the membrane filtration technique remains an approved method for both new construction and distribution samples, additional confirmation steps are now required when any bacteria is found to be present, leading to additional days of testing, increased turnaround time and cost. Effective immediately, Suburban Laboratories will no longer be using the membrane filter method.

Due to these rule changes, Suburban Laboratories has updated its policy to analyze all new construction samples by Colilert Presence/Absence method 9223B.  This allows for more efficient analysis and faster reporting of results.  It is understood that on some rare cases, a total count of coliform bacteria or e. coli is preferred.  In these situations, Suburban Laboratories will analyze samples via method 9223B using Quanti-tray to obtain a quantifiable bacteria value.  This procedure employs the same technique as in the presence/absence method, detects down to one (1) organism per 100 mL, and is an approved EPA method for drinking water samples.  If you require quantification of your coliform samples, you must notify your project manager and specify this on all paperwork when delivering samples to the lab.
