Plain English Guide for Testing and Reporting of Small Wastewater Systems

Guidance Manual of Approved Analytical Testing Procedures
January 2000

Task Force for Analytical Testing

This manual was a joint effort of the New York State Department of Environmental Conservation (NYS DEC), the New York City Department of Environmental Protection (NYC DEP), and the United States Environmental Protection Agency(US EPA). This document is a reference for the owners and operators of wastewater treatment plants in the NYC Watershed which have recently been required to increase the levels of monitoring performed at these facilities. The goal of this document is to: Inform the regulated community of the requirements for analytical testing under federal regulations, identify the accepted standard methods, and provide references for obtaining the necessary analytical testing equipment. This document does not endorse any particular make or model of analytical testing equipment. Procurement of equipment will be at the sole discretion of each facility owner/operator. Any questions regarding SPDES permit compliance should be directed to the appropriate NYS DEC Regional Office. Guidance regarding proper filing of the Discharge Monitoring Reports (DMR) can be obtained from the NYS DEC - DMR Reporting Manual. The NYS DEC - NYC Watershed Section thanks all who participated in the drafting and review of this manual.

This document is in no way intended to replace or supercede the need for proper training in safe and proper laboratory practices. It is intended to be a tool for the operator to use as an easy reference when conducting pH, dissolved oxygen, suspended solids, chlorine residual and temperature testing for DMR reporting.

Laboratory Practices

Safety

All employees must be vigilant in following the health and safety protocols at their facility. Personal Hygiene

  • Refrain from smoking and gum chewing while collecting samples and conducting analysis
  • Wash hands when finished collecting or analyzing samples and before smoking, eating or drinking
  • Wash clothing worn during sampling and analysis separate from other clothing

Laboratory

  • NEVER use mouth suction on pipetting for starting a siphon
  • ALWAYS add acid to water and pour a concentrated solution into a less concentrated solution while stirring
  • DO NOT put your nose directly over a container to smell the content. Instead, waft the vapor toward your nose
  • DO NOT look down the opening of a vessel unless it is known to be empty
  • INSPECT gloves before use
  • AVOID contact between chemical reagents and skin, eye, nose and mouth. Never use your fingers to stopper a sample bottle (when you are shaking a solution)
  • CLEAN-UP promptly clean up spills, using appropriate protective equipment.

General

Before beginning any analysis:

  • read through the entire procedure
  • Copy procedure and post near analytical device, for easy reference
  • prepare area by cleaning all surfaces, glassware and equipment.
  • gather all needed materials, reagents, equipment, etc.

Avoid contamination of your standards and reagents:

  • keep containers capped/stoppered at all times. Do not switch caps on containers
  • do not pipette directly from stock bottles, pour out approximate amount into a beaker first
  • never return excess solution or return used solution to stock bottles
  • follow recommended storage and shelf-life of all chemicals to avoid change in concentrations/strength

Proper Calibration of Instruments:

  • Always follow manufacturer's guidance for maintenance, calibration and storage of meters and electrodes
  • Most parameters are temperature sensitive, have calibration reagents and sample solution at the same temperature

DMR Testing/Methods/Equipment

pH

EPA - Methods for Chemical Analysis of Water and Wastes (Method 150.1)

  • Apparatus- "5.1 - pH Meter-laboratory or field model. A wide variety of instruments are commercially available with various specifications and optional equipment." ( p. 150.1-1)
  • Reagents- "6.2 - Secondary standard buffers may be prepared from NBS (National Bureau of Standards) salts or purchased as a solution from commercial venders. Use of these commercially available solutions, that have been validated by comparison to NBS standards, are recommended for routine use." ( p. 150.1-2)
  • Calibration- "7.2 - Each instrument/electrode system must be calibrated at a minimum of two points that bracket the expected pH of the samples and are approximately three pH units or more apart." ( p. 150.1-2)
  • Procedure- "8.2 - Place the sample or buffer solution in a clean glass beaker using a sufficient volume to cover the sensing elements of the electrodes and to give adequate clearance for the magnetic stirring bar." ( p. 150.1-2)
    • "8.2.1 - If field measurements are being made, the electrodes may be immersed directly in the sample stream to an adequate depth and moved in a manner to insure sufficient sample movement across the electrode sensing element as indicated by drift free (<0.1pH) readings." ( p. 150.1-2)

Standard Methods - For the Examination of Water and Wastewater 20th edition 1998 4500-H+ B. Electrometic Method

  • Apparatus - " For routine work use a pH meter accurate and reproducible to 0.1 pH unit with a range of 0 to 14 and equipped with a temperature-compensation adjustment." ( p.4-88)
  • Reagents - "For routine analysis, use commercially available buffer tablets, powders, or solution of tested quality." ( p.4-89)
  • Instrument Calibration - "In each case follow manufacturer's instructions for pH meter and for storage and preparation of electrodes for use." ( p.4-89)

What does this mean to a person filling out a DMR?

pH is a measurement of the intensity of the basic or acidic strength of water. It can best be illustrated by using a bar graph (pH Scale) that reads 0 to 14.

What to consider when purchasing a pH meter and electrodes:

  1. Your pH meter needs to be able to give reproducible readings to 0.1 pH unit with a range of 0-14.
  2. Do yourself a favor and make sure the pH meter you choose has temperature compensation.
  3. Electrodes: a glass electrode and reference electrode are required. They can be combined as one and are called combination electrodes. Generally the glass and reference electrode is considered more reliable than the combination.

Using the pH meter: Calibrate the pH meter by following the manufacturer's directions. Calibrate using two buffer solutions, that bracket the expected pH of the sample and are, three pH units apart. Purchase pre-made solution buffers of pH 4,7,and 10. They come color coded, standardized and are generally accepted by regulatory people.

  1. Calibrate pH meter before each use or once per day.
  2. Follow the manufacturer's instructions for proper maintenance and storage. Improperly maintained or stored meters/electrodes are subject to corrosion which leads to unreliable results
  3. Record pH calibration and temperature in your logbook!
  4. What you will need:
    • Equipment:
      • pH meter
      • Centigrade thermometer
      • Beakers
      • Absorbent disposable tissues
    • Reagents:
      • pH buffers (4,7,10)
      • Distilled /deionized water
      • Squirt bottles

TIPS: Perform analysis as soon as possible after sample collection. Hold no longer than 15 minutes. Buffers used for calibration and sample should be the same temperature (no greater than 10?C difference). Always keep buffer containers capped to prevent contamination.

NEVER REUSE buffers.
Always rinse the electrode well with distilled/deionized water before and after use and between placing in buffer solutions or sample. Wait till drifting has stopped before recording the reading. Protect glass electrode from scratches, do not bang against side of beaker or wipe with rough/gritty cloth/paper. Always turn the meter to standby or off before removing the electrode from solution.

Settleable Solids

EPA - Methods for Chemical Analysis of Water and Wastes (Method 160.5)

Summary of Method - "2.1- Settleable matter is measured volumetrically with an Imhoff cone." ( p.160.5-1)

Standard Methods - For the Examination of Water and Wastewater 20 th edition 1998 - 2540 F. Settleable Solids

  • 2. Apparatus - "The volumetric test requires only an Imhoff cone. The gravimetric test requires all the apparatus listed in section 2540D.2 and a glass vessel with a minimum diameter of 9 cm." ( p.2-59)
  • 3a. Procedure - " Volumetric : Fill an Imhoff cone to the 1-L mark with well-mixed sample. Settle for 45 min, gently agitate sample near the sides of the cone with a rod or by spinning, settle 15 min longer, and record volume of settleable solids in the cone as milliliters per liter." ( p.2-59)

What does this mean to a person filling out a DMR?

  1. Purchase an Imhoff cone, it is recommended that a replacement also be purchased and stored at your facility. Glass is considered superior, but is more expensive and breakable. Plastic is generally accepted as a substitute for glass.
  2. Purchase or make a holder for the Imhoff cone.
  3. Find a bench top at the facility that will not be disturbed for at least one hour each day.
  4. It is recommended that the person performing the Settleable Solids test, also get a timer. Place 1 Litter of well mixed effluent in the Imhoff cone. Set the timer for 45 min. When it goes off gently agitate sample near the sides of Imhoff cone with a rod or by spinning. Allow to settle 15 min longer.
  5. Record the settled solids. Report settleable solids as Milliliter per Liter mL/L.
  6. Be sure to clean the cone after each use to avoid traces of solids that may cause high readings.

Dissolved Oxygen

EPA - Methods for Chemical Analysis of Water and Wastes (Method 360.1)

Scope of Application - "1.1- The probe method for dissolved oxygen is recommended for those samples containing materials which interfere with the modified Winkler procedure such as sulfite, thiosulphate, polythionate, mercaptans, free chlorine or hypochlorite, organic substances readily hydrolyzed in alkaline solutions, free iodine, intense color or turbidity and biological flocs." ( p.360.1-1)

Apparatus - "5.1- No specific probe or accessory is especially recommended as superior. However, probes which have been evaluated or are in use and found to be reliable are the Weston & Stack DO Analyzer Model 30, the Yellow Springs Instrument (YSI) Model 54 and 55, and the Beckman Fieldlab Oxygen Analyzer." ( p.360.1-2)

Calibration - "6- Follow manufacturer instructions." ( p.360.1-2)

Standard Methods- For the Examination of Water and Wastewater 20 th edition 1998 - 4500-O G. Membrane Electrode Method

1. General Discussion - " Membrane electrodes provide an excellent method for DO analysis in polluted waters, highly colored waters, and strong waste effluents. They are recommended for use especially under conditions that are unfavorable for use of the iodometric method, or when that test and its modifications are subject to serious errors caused by interferences." ( p.4-135)

2. Apparatus - "Oxygen-sensitive membrane electrode, planographic or galvanic, with appropriate meter." ( p.4-135)

3a. Procedure - " Calibration : Follow manufacturer's calibration procedure exactly to obtain guaranteed precision and accuracy. Generally, calibrate membrane electrodes by reading against air...DO." ( pp.4-135, 4-136)

What does this mean to a person filling out a DMR?

To determine Dissolved Oxygen, it is important to decide what method you feel most comfortable with. Whatever you decide to use, keep in mind your results must use a method accepted by US EPA and Standard Methods and must be reproducible.

  1. Purchase a D.O. Meter. (It is also recommended that a replacement probe be purchased, and when it is put into service repair or replace so that you will always have a back-up probe.)
  2. Keep your operators manual and calibration instructions safe and easily accessible. ( If the original manual has the potential to get dirty or unreadable, copy needed pages and keep copies with your meter.)
  3. Air calibrate your D.O. Meter daily. If Air Calibrating the D.O. Meter, be sure that the there are no droplets on the membrane. This can cause a bad calibration.
  4. We recommend that the instrument be calibrated annually by a certified laboratory and more frequently as needed.
  5. It has been our experience that the membranes that are screwed in are easier to replace than those that are held in place with an O-ring.
  6. Record the D.O. Meter calibration in your logbook!

Appendix A

Handy Information

If a water use meter is used to estimate flows:

Take water meter reading, if your meter reads in cubic feet, you must report in GPD or MGD so; Meter Reading today - Meter Reading previous day X 7.48 = Gallons used. Example; July 20th the water- meter read 0872250cuft,July 19th it read 0871400cu ft = 850 cuft,

850 cuft X 7.48 = 6358 gallons reported as 6358 GPD (Gallons per Day). Or: Divide by 1,000,000 to get 0.006358 or 0.0064 MGD

To convert mg/L to loading lbs/day (can be used for BOD, Suspended Solids, Total Phosphorus):

The formula is:
Flow(MGD) X Concentration (mg/L) X 8.34 = lbs/day.
Example; (utilizing the flow calculated above and using the mg/L, reported by the contract laboratory,
for this example lets say 15 mg/L)

0.006358 MGD X 15 mg/L X 8.34 = 0.7956 lbs/day report as 0.8 lbs/day
