Patrick O'Brien has experience in water resource fields such as surface water hydrology, hydrologic data analysis, hydrologic modeling, GIS applications, and environmental compliance. He has a Master's in Environmental Science with a concentration in hydrology and water resources from UMass Boston. His experience includes collecting and analyzing hydrologic and water use data for watersheds in the Boston area, performing field work collecting streamflow and water quality data, and working as an intern for the MBTA and an Army base conducting GIS analysis and stream restoration work.
Assessment of Water Pollution of Water Bodies using GIS - A Reviewijtsrd
Quality and quantity of water bodies is considered main pillar for sustainable development. Assessment of surface water bodies is required for growing urban cities like Surat. Due to impact of urbanization, the surface water bodies of Surat City have been adversely affected. The main Scope of study is the qualitative classification of the Creek and Tapi River of Surat City based on the effective qualitative parameters in the Indian water standards for drinking purpose. The study focuses on spatial changes in surface water quality based on a combined examination of physical and chemical parameters.GIS is proper solution for analysing the useful information obtain from spatial and temporal data because this analysis extract information from the available spatial data which can be very helpful in the future decision making. To obtain spatial dissemination of surface water quality parameters (as COD, BOD, pH, DO, Turbidity, EC, TDS, TSS and Chloride), interpolating technique is used. Divya A. Lad | Dr. Mehali J.

Analysis of Water Quality Index for Groundwater in Gudur Mandal, SPSR Nellore...IJERA Editor
Groundwater has become a necessary resource over the past decades due to the increase in its usage for drinking,
water supply, irrigation and industrial uses etc. Groundwater resources are now facing threats due to
anthropogenic activities. The groundwater quality is equally important as that of quantity. Mapping of spatial
variability of groundwater quality is of vital importance and it is particularly significant where groundwater is
primary source of potable water. The present study has been undertaken to analyze the spatial variability of
groundwater quality for Gudur Mandal, SPSR Nellore District located in the Andhra Pradesh State. MS ExcelAnalysis
ToolPak is used for mathematical analysis of the parameters and ArcGIS Version 10.1 is used for the
spatial analysis and it is a powerful tool for representation and analysis of spatial information related to water
resources. A total of 280 bore well water samples are collected. The major water quality parameters such as pH,
Total dissolved solids, Total alkalinity as calcium carbonate, Total hardness, Chloride, Sulphate, Nitrate,
Fluoride, Iron have been analysed as per BIS 10500-2012. The spatial variation maps of these groundwater
quality parameters were derived and integrated through GIS. The final integrated map shows five priority classes
such as Excellent, Good, Poor, Very poor, Unsuitable for zones of the study area and provides a guideline for the
suitability of groundwater for domestic purposes

Master’s Research: Analysis of Anthropogenic Impacts to Water Availability Boston, MA
in Suburban Watersheds of the Boston Metropolitan Area Sept 2012-Aug 2014
Collected and analyzed hydrologic data as well as human water-use data for three large watersheds. Used
Excel spreadsheets to organize, calculate, analyze, and perform quality assurance on large datasets.
Categorized water stress in the watersheds at annual and seasonal time scales based on natural water
availability as well as direct human interactions (such as consumptive use). Used ArcGIS/Excel to model
storm runoff change over time (30 years) as a function of land use change. Presented research at the
UCOWR-NIWR-CUAHSI Conference at Tufts University, June 2014. Manuscript in review (Journal of
Hydrologic Engineering, submitted August 2014).
University of Massachusetts Boston Boston, MA
Hydrologic Field Technician May-Sept 2013
Manually collected streamflow and water quality data at various sites throughout MA as part of a research
project investigating the ecological effects of dam removal. Performed instrument calibration,
maintenance, and troubleshooting on stream gaging equipment and multi-parameter water quality
instruments. Field work partly consisted of weekly 24-hour overnight sampling and long distance travel.
