MUNICIPAL WATER SUPPLIERS

Lead and Corrosion

EPA and State regulatory agencies are focused on reducing the risk of corrosion of Lead into public water supplies. Retego technology gives public water supply managers the real-time data you need to know, NOW.  So that you know what is happening in your system, NOW!

  • Lead
  • Copper
  • Water quality parameters needed to calculate corrosion control indices or check for corrosion inhibitors:
    • WQPs:
      • Total alkalinity
      • Calcium
      • Total dissolved solids
      • Temperature
      • pH
      • Sulfate
      • Chloride
      • Sodium
      • Ortho-Phosphates
      • Silicates
    • Corrosion Indices
      • Langelier Saturation Index
      • Ryznar Stability Index
      • Puckorius Scaling Index
      • Aggressiveness Index
      • Calcium Carbonate Precipitation Potential
      • Modified Larsen Index
      • Chloride/Sulfate Mass Ratio

Revised Coliform Rule

Under the revised coliform rule, water systems that trigger Level 1 or Level 2 assessments must evaluate the system's potential for contamination and must address any found sanitary defect.  Our rapid analysis for Total Coliform and E. coli are under development, when completed they will allow you to narrow down points of contamination in near real time!

  • Total coliform
  • E. coli

Chloraminating water systems

Nitrification can lead to taste and odor, biofilm growth and coliform positive coliform samples.  Retego technology helps you identify critical parameters so you: 1) know what is happening throughout your water system and 2) are able to make real time adjustments.

  • Free Ammonia
  • Monochloramine
  • Total chlorine 
  • Free chlorine
  • Nitrite
  • Nitrate
  • Potential constituents
  • Dichloramine
  • Trichloramine

Other useful rapid water quality parameters at your fingertips:

  • Iron and/or manganese
  • Iron
  • Manganese
  • Polyphosphate
  • Hydrogen sulfide
  • Hydrogen sulfide
  • Arsenic
  • Total Arsenic
  • Arsenic +3
  • Arsenic +5
  • Perchlorate

Chromium

While only total chromium is currently regulated in every state, Chromium 6 is currently regulated in California and is a topic of federal regulation.

  • Total chromium
  • Chromium +6

MUNICIPAL AND INDUSTRIAL WASTEWATER

Plant Wastewater - wastewater discharges must be monitored for compliance with permit limits which include suspended solids, nutrients, oxygen demand and toxics

  • Nutrients
    • Ammonia
    • Nitrite
    • Nitrate
    • Total phosphorus
    • Heavy metals (limited to metals included in permit)

Operators and field technicians would benefit from quick tests to determine what kinds of treatments are required and whether those treatments have been effective.

Application: Drilling and Completion Crews

Water quality (pH, alkalinity, salt content, hardness, boron, iron and active chlorine from biocides) dictates what chemicals are required for drilling mud and fracturing fluid compositions.  Specifically, constituents in water from oil and gas operations must be determined for the following reasons:

Metals (and other inorganic ions) and organic constituents must be compatible with drilling mud chemistries to optimize drilling schedules, reduce maintenance/equipment costs and meet environmental standards for surface hole drilling.

Salt, metal ions, anions (especially borates) and organics must be monitored to optimize gel chemistries for fracturing operations. (Bad fracturing stages caused by unmanaged water quality can cost millions of dollars over the life of a well.)

Depending on the geological formation, one recovers between 3 to 11 barrels of water for each barrel of oil - this wastewater must be properly collected, stored and disposed of or optimally reused.  The accurate determination of normally encountered metals, anions, microbes and organic constituents is critical for blending wastestreams, reducing maintenance due to scaling and preventing corrosion of oilfield production and waste storage and transportation assets.

Monitoring water constituents is critical for EOR (enhanced oilfield recovery) to maximize hydrocarbon recovery and to prevent damage to the formation, especially when treated produced and flowback waste waters are utilized for flooding operations. 

Application: Salt Water Disposal Operations

SWD Plant operators and field technicians would benefit from quick tests to determine what kinds of treatments are required and whether those treatments have been effective.  Use our iron test and sulfide tests to discover general scaling and corrosion tendencies, saturation index for scale and/or corrosion potentials, oxygen concentration to see if an oxygen scavenger is warranted, and our soon-to-come anaerobic and aerobic bacteria tests to determine the need for, an efficiency of and biocide treatments.
