2 Puyallup White River TMDL Prioritize bacteria source screening in two creek basins discharging into King County s MS4 Boise Creek Jovita Creek 2

3 Multi-Pronged Approach Research Relationships Technical methods 3

4 Boise Creek Basin rural & ag uses Some piped conveyance Many roadside ditches 4

5 APPROACH -- PEOPLE The People Approach Build new relationships Leverage existing relationships Form partnerships Gain trust Work toward common goals 5

6 APPROACH -- PEOPLE Partners King County Stormwater Services King Conservation District Boise Creek citizens (farmers, cattlemen, homeowners) King County Science & Technical Support King County Environmental Lab King County Rural & Regional Services Public Health Seattle King County Washington State Department of Agriculture Washington Conservation Corps 6

7 APPROACH -- PEOPLE KC Stormwater Services Attend/participate in public events Get word out to explain FC TMDL work Listen & explain FC TMDL in chance encounters Get back to public when you ll say you will 7

8 APPROACH -- PEOPLE King Conservation District Ongoing positive relationships with residents voluntary Farm Plans Know farm and ranch history Runs Stream Stewards program volunteers who monitor the creek Can help landowners improve their BMPs 8

9 APPROACH -- PEOPLE KCD Stream Steward Training October 2013 KCD Fish Forest Family Tour Sept 2014 KCD Fair March

10 APPROACH -- PEOPLE King County Science & Tech Support Section Ray Timm, KC Science Section Gather & share microbial source tracking information Help perform recon & sampling 10

11 APPROACH -- PEOPLE King County Environmental Lab Learn more about microbial science culture methods (FC, EC) and qpcr techniques (DNA molecule-based) Work with Lab to schedule sampling Get help w/ data County s lab located in Seattle on Ship Canal near Seattle Pacific University 11

12 APPROACH -- PEOPLE King County Rural & Regional Services Staff have ongoing relationships with farmers & ranchers Staff know land use & history RRSS run cost-share projects with KCD 12

13 APPROACH -- PEOPLE Public Health Seattle King County Permits, inspects & approves septic systems Gave a septic training with King Conservation District in 2014 Health knows area/groundwater/septic Can investigate specific parcels Can streamline permit process Septic discharge to MS4 ditch Properly functioning septic system 13

14 APPROACH -- PEOPLE WA State Dept. of Agriculture Issues licenses for dairies Inspects licensed dairies for BMPs Willing to listen to King County Stormwater Services concerns 14

15 APPROACH -- PEOPLE WA Conservation Corps & King County Small Habitat Restoration Program (SHRP) May conduct stream restoration, such as buffer fencing Live-staking along Newaukum Creek stream buffer 15

16 APPROACH -- TECHNICAL The Technical Approach Desktop GIS analysis, looking for possible sources Research/build upon existing KC Science creek data Stream sample stations, from Boise Creek Bacterial Source Tracking Study 2011, Ray Timm 16

17 APPROACH -- TECHNICAL Technical Approach (cont.) Many visits to Boise Cr. basin Checking out roadside ditch Screening & sampling gear Obtaining Coliscan Easygel water sample Select/name/map MS4 sample points (42 to date) Screening & sampling event iterations 17

18 APPROACH -- TECHNICAL REAL LIFE IDDE EXAMPLE: Evidence of IC Gray discharge from private tile into MS4 Confirmatory sampling $2 Coliscan Easygel test on the sample yielded TNTC E. coli colonies Source Livestock or human? 18

19 APPROACH -- TECHNICAL More sampling Human Bacteroides and cow Bacteroidales tests IC confirmed Human source failed septic system Source eliminated New septic system in place 19

20 Jovita Creek basin Residential - all on septic Jovita Creek basin is in SW King County, between cities of Federal Way and Algona & Pacific. KC MS4 outfall to Jovita Creek road culvert 20

21 APPROACH -- RESEARCH Jovita Research paper files for flow data (MS4 not yet mapped) Field recon Goal: delineate actual MS4 basin 21

22 APPROACH -- RESEARCH Jovita Areas discharging to creek via MS4 better identified (blue dashed line) Includes new res. develop. outside topo. boundary 22

23 APPROACH -- TECHNICAL Drive/walk Jovita basin Select sample points (4 in creek, 8 in MS4 so far) Instantaneous screening Bacterial sampling iterations Possible Illicit Connection found, more source tracing investigation needed Documenting: maps, lab results, photos, reports 23

24 Upcoming King County Fecal Coliform TMDL Basins Bear-Evans Watershed Issaquah Creek Basin 24
