  • Page 2 WATER SCREENING TEST PROTOCOLS FOR STORMWATER MS4 GUIDANCE USING COLORIMETRIC AND TURBIDIMETRIC TECHNIQUES  OVERVIEW According the U.S. Census bureau the world’s population went from 2.5 billion in 1950 to 6 billion in 2000 and is on pace to exceed 9 billion by 2050. We will soon have 3 times the global population we had only in 1950, and with this growth comes enormous impacts on the surface of our globe.

    EXAMPLES OF OUTFLOWS Outfl ows attributable to a rainwater event can occur across a number of different environments. These include: • Agricultural runoff • Industrial sites • Construction sites • Irrigation runoff • Parking lots and pavement • Other While illicit discharges of various chemical constituents into stormwater drains represent a portion of the overall problem, these are not normally defi...
  • Page 4 titrant. The titration endpoint is identifi ed by the development of color resulting from the reaction with an indicator, by the change of electrical potential or by the change of pH value. Ion Selective Electrode An ISE is a transducer (or sensor) that converts the activity of a specifi c ion dissolved in a solution into an electrical potential, which can be measured by a voltmeter or pH meter.
  • Page 5 applicable in communities where hardness levels are elevated in groundwater due to karst or limestone terrain. In these regions, hardness can help distinguish natural groundwater fl ows present in outfalls from tap water and other fl ow types. Most discharge fl ow types are neutral, having a pH value around 7, although groundwater concentrations can be somewhat variable.
  • Page 6 Test Factor Methodology Action Level Ammonia Ammonia forms a colored complex with Nessler’s ≥50 mg/L Nitrogen Reagent in proportion to the amount of ammonia present in the sample. Rochelle salt is added to prevent precipitation of calcium or magnesium in undistilled samples.

  • Page 9 COLOR • SMART3 COLORIMETER Platinum Cobalt Method • No Reagents Required RANGE: 0–1000 color units MDL: 20 Cu METHOD: Color is determined by a meter that has been calibrated with colored standards of known platinum cobalt concentration. True color, the color of water in which the turbidity has been removed, is measured.

    SMART3 GENERAL OPERATING PROCEDURES THE KEYPAD The keypad has 6 buttons which are used to perform specifi c tasks. This button will scroll up through a list of menu selections. The button is used to select choices in a menu viewed in ENTER the display.

  • Page 21: Setting The Clock

    PC LINK The meter may be interfaced with any Windows-based 64 bit computer by using the LaMotte WaterLink Connect program and a USB cable. The program will store test information and results in a local database, and allow for exporting this data to a comma separated value (CSV) fi le. The meter will send the following data: time/date stamp, name of test, sample value, sample units, meter name, and location.

  • Page 22: Setting The Data Logger

    SETTING THE DATA LOGGER NOTE: Data from the data logger must be retrieved in the same language in which it was collected. The default setting for the data logger is enabled. The meter will log the last 500 data points. The counter in the center bottom of the display will show how many data points have been logged.

  • Page 23: Setting The Backlight Time

    SETTING THE BACKLIGHT TIME The backlight illuminates the display for enhanced viewing. The default setting is 10 seconds. If Button Control is chosen the backlight button on the key pad will act as an on/off switch and the backlight will remain on or off when the meter is being used.

  • Page 24: Battery Operation

     BATTERY BATTERY OPERATION The meter may be operated on battery power using a USB wall adapter or USB computer connection. If using the meter as a bench top unit, use the wall adapter if possible to extend the battery life. The meter will remain on when the USB adapter is used.

    Handle the tubes carefully, making sure the bottom half of the tube is not handled. LaMotte Company makes every effort to provide high quality colorimeter tubes. However, wall thicknesses and diameter of tubes may still vary slightly. This may lead to slight variations in results (e.g. if a tube is turned while in the sample chamber, the reading will likely change slightly).

     METER DISPOSAL Waste Electrical and Electronic Equipment (WEEE) Natural resources were used in the production of this equipment. This equipment may contain materials that are hazardous to health and the environment. To avoid harm to the environment and natural resources, the use of appropriate take-back systems is recommended.
  • Page 27 container and mix. Transfer back 10 mL of the diluted sample to the tube and follow the test procedure. Continue diluting and testing until a reading, which is in the concentration range for the test, is obtained. Be sure to multiply the concentration found by the dilution factor (the number of total 10 mL volumes used).
  • Page 28 DIRECT READING TITRATOR The Direct Reading Titrator consists of a plastic barrel, a plastic plunger, and a plastic adapter tip. Plunger Barrel Adapter tip The adapter tip reduces the size of the drops that are dispensed and increases the precision of the test results. DO NOT REMOVE THE ADAPTER TIP . INSTRUCTIONS These are general instructions for the use of the Direct Reading Titrator.
