Data Interpretation

  • Metals Calculator - Hardness-based Metals Criteria Calculator – The calculations in this spreadsheet are based on the criteria contained in 62-302.530 F.A.C. (5/04/2007). (if prompted for a password, choose cancel)
  • TEQ Guidance - This memorandum outlines proposed guidance for the evaluation of laboratory data associated with samples analyzed for dioxins and furans.
  • Unionized Ammonia

Documents

Laboratory Methodologies

  • 1,4-Dioxane - Available methodologies and recommendations by the Bureau of Laboratories for the analysis of 1,4-dioxane. Note: These recommendations do not constitute approval for any specific regulatory application.
  • Single Ion Monitoring Guidance - In response to numerous inquiries concerning the use of the Single Ion Monitoring (SIM) mode for analytes, the Standards and Assessment Section has provided this guidance that emphasizes the method-required quality control measures when using this technology. This document also identifies the program areas to which this technology is applicable.
  • Inorganic Methods Update - Listing of Deleted, Added and Retained Methods in 40 CFR Part 136.3 Table 1B (Inorganic Methods).
  • EPA Methods Update - The Environmental Protection Agency recently promulgated rules in the Federal Register that affect analytical methods for programs in the Clean Water Act, the Safe Drinking Water Act (drinking water, ambient water, waste water and sewage sludge).  This memo, issued jointly by the Department and the Department of Health Environmental Laboratory Certification Program,  outlines the interim implementation strategy for methods and procedures published in the March 2007 Federal Register notices. Additional information concerning frequently asked questions will be posted as they are made available.
  • CBOD Interpretation  - The National Environmental Laboratory Accreditation Conference issued an interpretation of control limits of glucose glutamic acid when performing the test for Carbonaceous Biochemical Oxygen Demand (CBoD).  This interpretation is the consensus of several experts in the field of BoD as well as state accrediting authorities and environmental regulatory agencies.
  • Discrete Analyzer Technology FDEP Environmental Assessment Section determines that method applications using discrete analyzer technology is an acceptable modification to the cited EPA methods and requires no application for alternative test procedure.  There was some confusion about the use of surfactants.  This revised version clarifies the Department's position that surfactants other than those specified (or not included) in the reference method are acceptable.
  • EPA Method 1664 - See this important information regarding the use of EPA Method 1664.
  • EPA Method 1669 - Clean hands sampling technique. The downloadable file is in PDF format (137 kB)
  • Modifications to EPA 625 - This EPA memorandum allows modifications and added flexibility to EPA Method 625 for environmental permitting and compliance monitoring under the Clean Water Act.
  • Ion-Imbalance Report and Spreadsheet - The results of a study to determine methods for identifying toxicity to marine animals resulting from an 'imbalance' of the major seawater ions.
  • Method of Standard Additions for Chlorine and Sulfur Dioxide Analyses -  Please find the SOP (PDF, 12 kB) for this procedure.
  • Petroleum Methods - Information regarding the FDEP's FLPRO method, the Massachusetts DEP method for Extractable Petroleum Hydrocarbons and the TPHCWG Analytical Method.Memo explaining the FLPRO method application.
  • Standard Methods 21st edition - Approved analytical methods from Standard Methods 21st edition for 40 CFR Part 136 (wastewater) and Part 141 (drinking water). (PDF, 100kB)

Reports and Audits

Emerging Substances of Concern (ESOC) - Summarizes the conclusions of an internal Florida Department of Environmental Protection (DEP) Workgroup that was formed to evaluate strategies to effectively address a wide variety of potential contaminants, commonly referred to as Emerging Substances of Concern, or ESOC.
