Cox-Colvin & Associates Celebrates

25 Years in Business!

With little more than two computers and a printer, enough money to last three months, and the trust of our wives and young children, we began Cox-Colvin & Associates, Inc. on February 2, 1995. Only days before, President Bill Clinton had invoked emergency powers to extend a $20 billion loan to help Mexico avert financial collapse, the OJ Simpson trial was underway, and the following month, Forest Gump would win the Academy Award. Our first office was in George’s basement where we shared space with a washer and dryer and a ping-pong table. We thought that if nothing else, we could always play ping-pong while waiting for the phone to ring. Thanks to several clients, from our prior work at Geraghty Miller, Inc., who were willing to take a chance on two guys in a basement, we hit the ground running and never played a single game of ping-pong.

Over the last 25 years, our talented staff have completed over 2,000 environmental assessment and remediation projects for more than 300 clients, remediated thousands of tons of contaminated soils and sediments, removed contaminants from more than 10 billion gallons of water for public consumption, managed millions of sampling and analytical results, developed a variety of database and GIS applications, prepared thousands of reports, provided expert testimony in legal cases, assisted clients with compliance issues, and helped shape environmental regulations and guidance. Over the last decade, we invented tools used worldwide in the assessment of soil gas conditions and have become internationally recognized experts in the field of vapor intrusion. To prepare for the next 25 years, we are expanding our expertise to include the development of groundwater resources, assessment and mitigation of asbestos, as well as the assessment and remediation of emerging contaminants such as PFOS and PFOA.

As we celebrate the first 25 years of business, we would like to take this opportunity to thank our loyal and talented staff, our families, friends, business associates, and clients who made the last 25 years possible. We could not have done it without you.   Thank you.

We have shared our story; we would love to have you share your Cox-Colvin piece of history or let us know how we are doing.

Sincerely,

Ohio EPA and Ohio Department of Health Launch PFAS Website

Objective 5 of the December 2019 Ohio Per-and Polyfluoroalkyl Substances (PFAS) Action Plan for Drinking Water called for the Ohio EPA and the Ohio Department of Health (ODH) to develop and disseminate educational information to the public to increase awareness and understanding of PFAS-related compounds and relative risk of exposure to PFAS through drinking water and other exposure pathways. In fulfillment of Objective 5 of the Action Plan, Ohio EPA and ODH recently launched Ohio’s PFAS web site.

The webpage is organized around Frequently Asked Questions (FAQs), Current Activities, Health, Public Drinking Water, Private Drinking Water, Data, and Other Resources. Consistent with the Action Plan requirements, much of the information on the webpage is directed toward PFAS exposure and risks, and what the public can do to reduce exposure.

Navigating to the website from the Ohio EPA home page is not obvious. We find the easiest way is to search for PFAS from the home page or use the Division of Drinking and Groundwaters (DDAGW) Site Links on the right-hand side of the DDAGW page.

World Economic Forum Report on Global Risks Finds Top Five Global Risks are Environmemtal

In advance of its annual meeting in Davos, Switzerland, the World Economic Forum released its Global Risk Report 2020. For the first time in its 15-year history, the top five global risks in terms of likelihood to occur were all environmental related. In terms of global risk impact, three of the top five risks were identified as environmental related, with Climate Change Inaction beating out Weapons of Mass Destruction for the number one spot.

Waters of the United States Update

On January 23, 2020, Andrew Wheeler, Administrator of the U.S. EPA, and R.D. James, Assistant Secretary of the Army for Civil Works (U.S. Army Corps of Engineers), signed the Navigable Waters Protection Rule, which is the Trump administration’s replacement of the Obama-era Waters of the United States rule of 2015. This is the government’s latest attempt to define which water bodies are under Federal jurisdiction.

H2Ohio Water Quality Plan to Protect Ohio’s Water

Last November, Governor Mike DeWine announced a water quality program designed to reduce harmful algal blooms in Ohio’s lakes, improve wastewater infrastructure, and prevent lead contamination in drinking water. On January 15, 2020, Governor DeWine and Ohio Department of Agriculture Director Dorothy Pelanda announced that $30 million in H2Ohio funding will be available starting this month for Ohio farmers in fourteen counties in northwestern Ohio to implement best management practices in order to reduce nutrients entering the Maumee River and Lake Erie.

Ohio EPA Issues Draft Water Quality and Assessment Report

EPA recently released the draft 2020 Integrated Water Quality Monitoring and Assessment Report for public review and comment. This report, updated every two years, is required by the federal Clean Water Act (CWA) to fulfill two purposes: 1) to provide a summary of the status of the State’s surface waters; and 2) to develop a list of waters that do not meet established goals (i.e. impaired waters). Under the CWA, once impaired waters are identified, the state must act to improve them. Typically, the actions include developing restoration plans [total maximum daily loads (TMDLs)]; water quality-based permits; and nonpoint source pollution control measures. As such, this report provides information and direction to much of the State’s work in water quality planning, monitoring, financial/technical assistance, permitting and nonpoint source programs.This and past assessment reports are a good starting point for any Ohio surface water work.The draft report also includes an overview of Ohio’s groundwater quality. Ohio EPA will be hosting a webinar on the draft report on March 2 and will be accepting comments through March 13, 2020.
