One of Healthy Urban Waters important initiatives is the development of field-based research advancements and capabilities at the evolving urban field stations at the Lake St. Clair Metropark (LSCMP), Belle Isle, and Great Lakes Water Authority (GLWA) Waters Works Park Pilot Plant. Funding from this grant in addition to internal funding has gone towards supporting seed projects, which are summarized below.

Improving Urban Water Monitoring Through Citizen Science
Pricincipal Investigator: Donna Kashian
Associate Professor, Biological Sciences
Management of many urban rivers throughout North America and Europe benefit from volunteer monitoring programs, or citizen science, to monitor water quality. Despite these efforts (particularly in the Great Lakes) and their utility for management decision, volunteer data remains under-utilized in traditional research and state management agencies. In part, this is due to a lack of truck among researchers about the quality and reliability of data. This project aims to provide an explicit comparison between academic and volunteer site assessments. In addition, water quality will be independently assessed through a suite of standard water quality parameters.
Microbial Contamination of Beaches in Huron to Erie Corridor: Investigating Dynamics and Potential Sources
Principal Investigator: Dr. Jeffrey Ram, Ph.D.
Professor, Department of Physiology, School of Medicine
Lab: Belle Isle
This project aims to further the understanding of E.coli levels in the Detroit River and further the capabilities of measuring E.coli. Water will be sampled at the Belle Isle beach and Sand Point beach in order to monitor E.coli levels. E.coli will also be analyzed through NextGen sequencing in order to compare levels and other community dynamics. Following this, sequencing data will be used to develop PCR primers and probes for 25 high risk harmful micro-organisms and optimize for use as a quick scan tool for microbial risk in recreational waters. Developing and applying sequencing methods have a great potential for risk assessment and management related to microbial contamination by providing rapid and accurate identification of the microbial community and identifying probable sources of such contamination. This project is a collaboration between two international laboratories located in the USA and Canada.

Investigating occurrence and effects of endocrine disruption due to environmental contaminants in Detroit waterbodies
PI: Tracie Baker, DVM, PhD
Assistant Professor, Institute of Environmental Health Sciences
Lab: GLWA Water Works Park
Scientific and public concern is growing in response to ongoing reports of endocrine disrupting chemicals (EDCs) in waterways due to their potential effects on wildlife and human health. These EDCs include pharmaceutical, personal care, agricultural, and industrial byproducts that enter the waterways via purposeful dumping, runoff, and wastewater treatment plants (WWTPs). Pharmaceuticals and personal care products enter the environment because WWTPs are not specifically designed to remove these types of chemicals. Studies have shown that EDCs can have a profound effect on development, reproduction, and the immune system. My previous research, using zebrafish as a model, has shown reproductive abnormalities and a consistent change in sex ratio favoring females following exposure to low levels of an EDC during juvenile development that persisted in subsequent generations. The overall project goals are to 1) determine the occurrence of known EDCs in Detroit waterbodies and 2) assess whether chronic exposure to this EDC mixture can affect sexual development and immune function. Implications of this study will include identifying etiologies of environmentally-induced disease in humans and anthropogenic pressures on reproductive capacity of wild fish populations.
A Pilot Study to Evaluate the Viability of Real-time Source Water Early Warning System for Volatile Organic Compounds (VOC)
PI: Dr. Judy Westrick, Ph.D.
Director, Lumigen Instrument Center
This pilot will evaluate the efficiency and sustainability of two online VOC (volatile organic compound) monitoring systems for use by drinking water treatment plants. The long term goal is to create an effective, robust, and affordable real-time drinking water protection network using online VOC monitoring. This six month pilot includes the setting up of the VOC monitoring system in two locations (the Great Lakes Water Authority (GLWA) Water Works Park Pilot Plant and the Marysville Drinking Water Treatment Plant), training operators, and summarizing the service and economic logistics of the two piloted monitoring systems. This pilot study is designed to address problems identified during the original span of the Huron to Erie Real-time Drinking Water Protection Network (HE-Network), a real-time drinking water quality monitoring network that operated in the corridor from 2006-2009 and provided early detection data for contamination from chemical spills and other public health threats. The pilot study will address: 1) resolving the "high" maintenance of the original system; 2) establishment of network governance; 3) security of funds for continued operation.
