Intro
Michael Noll is a hydrologist with the USGS New York Water Science Center and a licensed New York State Geologist. Michael graduated Summa Cum Laude from Stony Brook University in 2009 with a Bachelor’s Degree of Science (Geology), and in 2015 with a Master's of Science (Hydrogeology). Since 2007, Michael has worked on various environmental investigations to inform rehabilitation efforts of the New York City water supply system that is used to distribute potable water to New York City’s 8 million residents and another 1 million residents in upstate New York. Currently, Michael is working on a project to assess the effects of leakage from the Catskill and Delaware Aqueducts on the local bedrock and overburden aquifers in southeastern New York using a multidisciplinary approach.
Michael also oversees a cooperative program with the Suffolk County Water Authority which coordinates drilling activities and allows for cost-effective hydrogeologic data collection. Lithologic and geophysical data are analyzed on site to identify major hydrogeologic contacts and inform production well construction.
Michael has been working with the Shinnecock Nation on the south fork of eastern Long Island since 2014 on projects that help support decision making related to the Tribe’s natural resources. These projects include defining baseline hydrologic conditions, characterizing the movement and distribution of shallow groundwater beneath the tribal lands, and identifying sources of potential contamination to the surficial aquifer and coastal ecosystems. Michael participates in an annual training event to strengthen the technical capacity of the Shinnecock Tribe in managing their natural resources, and to establish and maintain positive relationships between the USGS and the Tribal Government.
Michael is also a subject matter expert for the USGS Geospatial Data Collection Group which provides technical guidance, method development, and training to the Water Mission Area for 9 geospatial disciplines. These disciplines include global navigation satellite systems, trigonometric leveling, differential leveling, storm-tide monitoring, bathymetry, light detection and ranging, datum conversion, photogrammetry, and geodesy.

Hydrogeologic and Geochemical Assessment of the Effects of Leakage from the Catskill and Delaware Aqueducts on the Local Bedrock and Overburden Aquifers in Southeastern New York
PROBLEM As part of an effort to sustain a viable water-supply system for 8 million residents in New York City, and 1 million other residents in upstate New York that rely on City water, the New York City Department of Environmental Protection (NYCDEP) has requested a multi-disciplinary study by the U.S. Geological Survey (USGS) to determine the source(s) of water to surface-water sites (springsDocumenting Hydrogeologic Information Obtained from Deep-Borehole Drilling in Suffolk County, New York
Background Borehole drilling and well-installation are costly procedures, and securing funding for new well installation for the sake of research is often difficult.The Suffolk County Water Authority (SCWA) maintains a large network of deep wells for public supply that is constantly being upgraded as water demands increase.
