Sample containers vary for the job at hand Pre-sampling Information

Watershed Watch Chain of Custody Record The sampling containers are pre-marked with a unique Site Number The Site Number should match the number on the “Chain of Custody Record” Pre-sampling Information
8
I received a bottle with a site number I don’t recognize! Check the documents in your packet, you may have been randomly assigned to collect a blank or a duplicate Pre-sampling information
9
Blank - A sample bottle filled while at the stream site with distilled water Serves as a check for possible contamination during sample handling or processing at the labServes as a check for possible contamination during sample handling or processing at the lab DO NOT indicate that the sample is a blank – the lab should not knowDO NOT indicate that the sample is a blank – the lab should not know Pre-sampling Information
10
Duplicate - A sample bottle filled with stream water at your site at the same time as your regular sample Serves as a check for variability among samples that should yield approximately the same lab resultsServes as a check for variability among samples that should yield approximately the same lab results DO NOT indicate that the sample is a duplicate – the lab should not knowDO NOT indicate that the sample is a duplicate – the lab should not know Pre-sampling Information

Basicequipmentneeded Collection Procedures
13
Selecting your sample collection location Collection Procedures On your first visit to your site, select an area of the stream where the flow is concentrated and where you can completely submerge and fill the bottle without touching the bottom NOTE: It is important that you collect your sample at the same location each time
14
Concentrated Flow Location Collection Procedures
15

17
Grab Sample Collection Enter stream at a downstream location Enter stream at a downstream location Walk upstream to avoid disturbing bottom Walk upstream to avoid disturbing bottom Collect sample at the same location each time in Collect sample at the same location each time in the middle of your concentrated flow location the middle of your concentrated flow location and at mid-depth of stream and at mid-depth of stream Collection Procedures
18
Grab Sample Collection Collection Procedures 0 = Dry 1 = Ponded 2 = Low 3 = Normal 4 = Bank Full 5 = FLOOD! Do not sample during these flow conditions Flow Rate
19
Put on disposable gloves Put on disposable gloves DO NOT RINSE BOTTLE DO NOT RINSE BOTTLE Point mouth of bottle directly over surface of water, dip Point mouth of bottle directly over surface of water, dip and scoop bottle upstream beneath water surface, and and scoop bottle upstream beneath water surface, and through water column in one swift motion to fill above through water column in one swift motion to fill above line marked on bottle line marked on bottle If preservative is in bottle, take caution to angle mouth so If preservative is in bottle, take caution to angle mouth so as not to spill any while collecting sample as not to spill any while collecting sample Cap container, leaving at least a small airspace at top to Cap container, leaving at least a small airspace at top to allow lab mixing allow lab mixing Place in wet ice immediately Place in wet ice immediately ForE. coli For E. coli grab sample collection: Collection Procedures
20
Put on disposable gloves Put on disposable gloves Rinse bottle with stream water three times Rinse bottle with stream water three times (fill bottle ¼ full of stream water, cap, shake, and discard downstream) Point mouth of bottle upstream (against the flow), Point mouth of bottle upstream (against the flow), submerge entire bottle to mid-depth of stream, submerge entire bottle to mid-depth of stream, scoop and fill scoop and fill Rinse cap in stream and cap bottle Rinse cap in stream and cap bottle Add preservative (if necessary) and place in wet ice Add preservative (if necessary) and place in wet ice Collection Procedures For grab sample collection other thanE. coli: For grab sample collection other than E. coli:
21
What to do if you get a chemical on you For emergency first aid in the field, flush For emergency first aid in the field, flush affected area with large amounts of water affected area with large amounts of water and seek medical attention immediately and seek medical attention immediately Follow the first aid procedures found on Follow the first aid procedures found on the Material Safety Data Sheets (MSDS) the Material Safety Data Sheets (MSDS) Equipment Chemical Safety
22
Samples must be kept immersed in wet ice Samples must be kept immersed in wet ice (but not frozen) until received by laboratory Some samples may require other preservatives Some samples may require other preservatives (check your sample event packet) Preservation
23
Like containers, preservation methods vary (You don’t have to memorize these) Preservation
24
Preservation Sample Holding Time: length of time a preserved sample can be stored length of time a preserved sample can be stored after collection and before it is analyzed without after collection and before it is analyzed without significantly affecting the results significantly affecting the results from the minute you collect a sample, the from the minute you collect a sample, the clock starts ticking on the holding time clock starts ticking on the holding time varies for different types of analysis varies for different types of analysis established by the US Environmental established by the US Environmental Protection Agency Protection Agency
25
E. coli = 6 hours maximum Other than E. coli = Follow holding time instructions received in your sampling event packet Preservation Sample Holding Times

Transportation 1. Make delivery arrangements before the sampling event before the sampling event 2. Take your sample and COC to the designated drop-off to the designated drop-off location location 3. Double-check your recordkeeping paperwork recordkeeping paperwork 4. Make sure to sign your COC Sample Delivery

InterpretationMetals A fish consumption advisory is in effect statewide All Kentucky waters are under advisory for mercury. Women of childbearing age and children 6 years of age or younger should eat no more than one meal per week of freshwater fish. Adult men and other women are not included in the consumption notice. All Kentucky waters are under advisory for mercury. Women of childbearing age and children 6 years of age or younger should eat no more than one meal per week of freshwater fish. Adult men and other women are not included in the consumption notice. This is not an emergency as organic mercury can occur This is not an emergency as organic mercury can occur naturally in the environment and does not affect swimmers, skiers or boaters. Fish can accumulate these low levels of mercury by eating plankton and other small aquatic creatures.
