Our Practice

Gordon & Rosenblatt advises Clients on matters pertaining to chlorine, chlorine dioxide, ozone and related oxyhalogens, with an emphasis on water treatment.  Our work often involves chemical products and processes for the control of microorganisms that can cause disease (infection), destroy critical infrastructure (corrosion) and compromise products and processes (biofouling).

The unusual depth and focus of our practice keeps us current with progress in science and technology, as well as with changes in laws, rules and regulations pertaining to water treatment.

Our work starts with a detailed understanding of the chemistry, which uniquely informs our approach to a range of scientific, business, legal and regulatory challenges. 

We help our Clients to measure, characterize and understand in detail the observed (sometimes unexpected) chemical reactions that can affect products and processes. Often, we are able to determine boundary conditions, important to avoiding (potentially catastrophic) events associated with unanticipated upset conditions.

We advise Clients on matters related to the environmental chemistry, transport and fate of oxyhalogens. This work includes the development of applications for government permits as well as litigation support and expert testimony.

We help Clients to use oxyhalogen disinfectants efficiently and effectively, to control harmful microorganisms in a variety of applications.  

We help Clients to understand and comply with laws, rules and regulations that apply to the transport, handling and application of oxyhalogens, as well as comprehensive monitoring, recordkeeping and reporting requirements. 

We help Clients to design and implement comprehensive, regulation-compliant water treatment programs, with careful attention to the measurement and management of disinfection byproducts, such as bromate ion, chlorite ion, chlorate ion and perchlorate ion.


May 1, 2012. The US Environmental Protection Agency (EPA) has published a list of contaminants  that public water systems will monitor as part of the agency’s unregulated contaminant monitoring program. The chemical contaminants listed include chlorate ion, which is associated with drinking water disinfectants chlorine dioxide and hypochlorite (bleach).

 American Water Works Association (AWWA) Water Quality & Technology Division names Best Paper 2012.   Stanford, B. et al. "Perchlorate, Bromate, and Chlorate in Hypochlorite Solutions: Guidelines for Utilities" (Journal AWWA, Vol. 103, Issue 6) describes recent work to develop a predictive model for quantifying the by-product formation in hypochlorite solutions during storage.  Dr. Gilbert Gordon, a co-author of the paper, is Distinguished Research Professor (Emeritus) of Chemistry at Miami University of Ohio and a Principal of Gordon & Rosenblatt, LLC. 

September 18, 2011.  The International Ozone Association (IOA) has announced that Gilbert Gordon, a Past President of IOA, will be awarded the Morton J. Klein Medal of Excellence. The inscription on the medal reads: "An award of excellence to recognise contributions of the highest order to the International Ozone Association in commemoration of the clear vision, diplomatic proficiency, and unparalleled leadership which characterised the life of Morton J. Klein."  Dr. Gordon is Distinguished Research Professor (Emeritus) of Chemistry at Miami University of Ohio and a Principal of Gordon & Rosenblatt, LLC.
