Georgia Adopt-A-Stream/Wetland

  • What is it?

    • Georgia’s volunteer water quality monitoring

      program

  • Program Goals

    • A: Increase public awareness

    • D: Collect quality baseline water quality data

    • O: Gather observations

    • P: Encourage partnerships between citizens & local government

    • T: Provide tools & training

Physical/Chemical Monitoring

  • Purpose: Gather info about specific water quality characteristics

  • In addition to visual observations and weather information, Coastal AAW recommends monitoring these core measurements:

    • Temperature

    • Dissolved Oxygen

    • pH

    • Salinity

    • Clarity/Secchi

  • Nutrient testing, alkalinity, and settleable solids may be added to your list as interest and equipment allows.

EPA Quality Assurance Project Plan

  • Quality Assurance Quality Control (QA/QC)

  • Only individuals are

  • certified

  • Certification is valid for one year

  • Volunteers must attend an annual recertification workshop

  • Only certified volunteers can submit data


Georgia coastal adopt a wetland chemical training

To Become a Certified QA/QC Volunteer…

  • FIELD: In the field, volunteers

  • must achieve results within the duplicate precision rules of those obtained by the trainer

  • WRITTEN: Volunteers must

  • pass a written evaluation with

  • a score of at least 80%


What is a watershed

What is a Watershed?

  • A watershed is the land area from which water, sediment, and dissolved materials drain to a common point along a stream, wetland, lake or river.

  • Its boundaries are marked by the highest points of land around the waterbody.


Georgia coastal adopt a wetland chemical training

Where, When and How Often?

  • Where: Same site location and elbow deep

  • When: Same time of day, same tidal stage, and during normal flow conditions

  • How often: At least once a month


Safety considerations

Safety Considerations

  • If conditions are too dangerous to sample…

    DON’T SAMPLE!

  • Wait until storm has stopped and strong flow has subsided

  • Never sample alone

  • Remember to wear gloves and boots

  • Use waste bucket to dispose of chemicals!

  • Receive permission from land owner before going onto private property

1. Temperature (°C)

  • Measurement:

  • In the shade, away from direct sunlight.

  • Take air temperature before water temperature.

  • Single measurement for each parameter

  • Measured in degrees Celsius (°C)

  • State Standards for Water Temperature:

  • Less than 32.2°C (90°F)

  • Importance:

  • Temperature/dissolved oxygen relationship:

    The higher the temperature, the less oxygen the water can hold.

  • Life adapts to a narrow range of temperatures. Changes of only a few degrees can affect the life in a stream.

  • Temperature affects feeding, respiration, and aquatic metabolism.


2 dissolved oxygen mg l or ppm

2. Dissolved Oxygen(mg/L or ppm)

  • Measurement:

  • RINSE sampling bottles twice before collecting sample

  • Take two samples for duplicate precision.

    • Two samples must be within +/- 0.6

    • If not, take another sample until two are within that range.

  • Measured in mg/L or ppm (1 mg/L = 1 ppm)

  • State Standards for DO levels:

    • Average of 5 mg/L for Georgia streams

    • A minimum of 4 mg/L

    • Trout streams: Average of 6 mg/L and a minimum of 5 mg/L

  • Importance:

  • Needed for respiration for all aquatic life

  • Can be altered by other physical/chemical parameters

2. Dissolved Oxygen

  • Inversely related to temperature:

    • As temperature increases, DO decreases

    • As temperature decreases, DO increases

  • DO levels may increase due to

    • diffusion from the atmosphere,

    • plant metabolism as a waste product of photosynthesis

    • turbulent mixing (riffles)

  • DO levels may decrease due to

    • warm temperatures

    • an overload of decaying organic matter (due to excess nutrients)

    • slow moving, deep water

3. pH (su)

  • Measure of hydrogen ions (H+)

  • Measured on a 0-14 scale

  • Pure water has equal amount of H+ and OH- ions and has a pH of 7

  • Brackish/salt water pH values <7 can be 7.2-8.5

  • Measurement:

  • Rinse sampling bottles twice before collecting sample

  • Take two samples for duplicate precision.

    • Two samples must be within +/-0.25 standard units

    • If not, take another sample until two are within that range.

  • State Standards for pH:

  • Between 6 and 8.5

  • In coastal areas pH is normally above 7 and can be 7.2-8.5

  • Importance:

  • Aquatic organisms are sensitive to pH fluctuations


4 salinity ppt

4. Salinity (ppt)

  • Measures amount of dissolved salts in water

  • Measurement:

  • Instrument:Refractometer

  • Units are parts per thousand (ppt)

  • Take two samples for duplicate precision.

    • Two samples must be within +/-1.0 ppt

    • If not, take another sample until two are within that range.

  • General salinity ranges:

    • Freshwater 0-5 ppt; Brackish water 5-30 ppt

    • Saltwater 32+ ppt

  • Importance:

  • Aquatic plants and organisms are sensitive to changes in salinity

  • Changes depending on amount of rainfall and

  • tidal stage


5 secchi disk cm

5. Secchi Disk (cm)

  • Measures clarity of the water

  • Includes all suspended particles in a sample

  • Measurement:

  • Instrument: Secchi Disk

  • Finds ‘Secchi Disk Depth’ in cm

  • Take two samples for duplicate precision:

    • Two samples must be within +/-10cm

    • If not, take another sample until

    • two are within that range.

  • Importance:

  • Affects growth of plants by changing the

  • availability sunlight

  • Affected by seasons, weather conditions, algal blooms, and amount of suspended particles

Nutrients

  • Nitrates

    • A nutrient found in the water from fertilizers or animal waste. Sewage is the main contributor.

    • Normal background levels are below 1ppm

  • Phosphates

    • A nutrient found in water from soaps, fertilizer, animal waste, industrial effluent and sewage

    • Normal background levels are below 0.1ppm

    • Excess nutrients can cause algal blooms, affect sensitive macroinvertebrates, and decrease dissolved oxygen levels

Chemical Kit Maintenance & Disposal

  • Keep chemical kits in a cool, dark place.

  • Replace chemicals when expired or contaminated

  • Disposal of chemicals:

    Used: flush down drain (water trt facility)Contaminated/expired: Hazardous waste day or return to AAS/AAW office for disposal

  • Contact Coastal Adopt-A-Wetland office for replacement equipment or reagents
