(Chemistry)
What was measured in 2014? 22 volunteers
144 sample sets collected
Nutrients (Phosphorus, Nitrogen)
Sediments (Total Suspended Solids)
Bacteria (E. coli)
Other (Dissolved Oxygen, pH, Temperature,
Conductivity)
71 flow measures
45 investigative sample sets
3 storm samples
Long-term sites
Investigative sites
Bacteria study sites
WQ Program:
3 counties
71 sites
28 creeks, 5 river sites
Long-term sites
Investigative sites
2014:
2 counties
27 sites (9 new)
9 investigative sites
Total Phosphorus in Wayne Co.(mg/L)
TSS in Wayne Co. (mg/L)
E.Coli in Wayne Co.
(cfu/100 ml)
Conductivity in Wayne Co. (µS)
Dissolved Oxygen in Wayne Co. (mg/L)
Summary Conclusions Macroinvertebrate diversity seems to be stabilizing
Phosphorus is high and stable throughout
Big September storm drove sediment runoff event
E. coli high and increased in 2014, except in Woods and Smith Creeks (Lower Huron)
Conductivity high and increasing (salts?)
Dissolved oxygen good except at Brownstown, Silver and Upper Ecorse Creeks
Investigatives and storms to come in report
Planning for 2015 Continue with 4th year of WQ monitoring and 11th year
of macroinvertebrate monitoring
Improve storm sampling frequency with remote controls (if possible)
Additional sampling by Wayne County at 20-30 sites
Plan for flow monitoring in 2016
