Ronald L. Miller, the founder of Chem-Hydro, has developed unique techniques for (1) relating major-ion (calcium, magnesium, sodium, potassium, chloride, sulfate, bicarbonate, etc.) concentrations to specific conductance (Miller et al, 1988) and using this relationship and others (Miller and Sutcliffe, 1982) in an expert system to perform advanced major-ion quality assurance, (2) developing indices that use major ion concentrations for tracking the migration of contamination in ground water (Miller and Sutcliffe, 1982), (3) measuring and modeling light attenuation in water (McPherson and Miller, 1987, 1994; Hanlon et al, 1998), (4) measuring and modeling light behavior at the air-water interface (Miller and McPherson, 1995), (5) modeling residence time of water in estuaries with relatively simple geometries using salinity and inflow data (Miller and McPherson, 1991), (6) water-quality trends in the Everglades and Big Cypress National Preserve (Miller et al, 2004), and (7) the conversion of photosynthetically active radiation (PAR) to total solar radiation (TSR) and vice versa.

 (Miller, 2006). The theoretical and practical value of his creative approaches to his scientific studies resulted in his inclusion in 7 national and international Who’s Who listings.

Ronald L. Miller has academic training in analytical and environmental chemistry from the                    University of Florida at Gainesville, Florida. He developed unique solutions and tools for water-quality and light behavior studies. During                     his 35 years with the U.S. Geological Survey, he worked as an analyst in 2 USGS laboratories. Later, he worked as a research                          chemist in the USGS National Research Program and as a hydrologist and research hydrologist doing field studies of general water                         quality, environmental contamination, natural radium and radon radioactivity in the environment, light attenuation, light at the                               air-water interface, and the residence time of water in the Charlotte Harbor Estuary. He worked on the southern Florida National                        Water Quality Assessment (NAWQA) as the surface-water chemist. His study sites include the Florida phosphate district,  Sarasota                         County, Charlotte Harbor, Tampa Bay, Lake Okeechobee, the Everglades, the Big Cypress National Preserve, and the Arthur R.                         Marshall Loxahatchee National Wildlife Refuge.
