Water Rangers Test Strip Monitoring Protocol
Test strips are dated on the bottom of the bottle. Never use expired test strips.
Never wash and reuse sample bottles with soaps or detergents. Clean sample bottles with distilled water and clean ammonia sample vials with tap water.
Test strips are to be used as indicators for levels of pollution that may trigger a more extensive chain of custody analysis at a certified laboratory. Test strips can also show trends in waterway health over time.
Test strips alone should never trigger a violation complaint unless combined with visual, photo, or video evidence of a manure discharge; a water quality problem; or an operational violation (e.g., manure in the water, strong smell of manure in the water, a significant fish kill, runoff from a land-application field, manure spreading in the rain, etc.).
Items for a Monitor’s Sampling Toolkit:
- Testing strips
- Digital/phone camera (with time-date stamp; zoom capability also useful) for taking photos of area conditions, what the water looks like, and what the test strip results show
- Details of facility you’re investigating (name, address, phone number, township, section #, etc.)
- DOT road maps that include right-of-way information
- Drain maps (can be surface water or tiled)
- Clean 100mL bottles for water samples
- Water pole for sample collection
- Rubber, latex, or nitrile gloves
- Distilled water for rinsing hands and sampling pole
- Hand sanitizer
- Notebook to document what you see
- Cell phone and charger
Have your agencies’ pollution emergency phone numbers to report any manure discharge!
Water Rangers Monitoring Step-by-Step Guidelines
-
Prep materials to take a water sample
- Grab a sampling bottle from your kit (we use 100mL bottles).
- Mark bottle with date, time, and location (use tape if you want to reuse bottles).
-
Take water sample(s)
- Two options for sampling:
- Sampling in the waterway: Walk to middle of waterway if possible, make sure to choose a sample site that isn’t disturbed.
- Sampling from the bank: Stand on the bank of the waterway and use a sampling pole to take sample close to the middle.Â
- Dip sample bottle into water 3-4 inches below the surface, fill, and pour water out to rinse bottle. Do this at least 3 times.
- Do not touch inside of bottle.
- Avoid collecting surface water.
- Two options for sampling:
-
Analyze the sample
- Analyze the sample at a safe place (we recommend you put your water sample on ice in a cooler and go to a safe place to do the analysis).
- Use test strips. Follow the instructions for each test-strip test.
