Water-Quality Characteristics, Calculated Nitrogen Loads, and Characteristics of Simulated Recharge Areas for Selected Stream Reaches on Cape Cod, Massachusetts, 2018-2021

This data release presents water-quality and streamflow data from 12 streams on Cape Cod, Massachusetts, which were used to identify potential land areas that are sources of high nitrogen loading from groundwater directly to streams. The sources of nitrogen loading to groundwater in this region include wastewater from septic systems and fertilizer and stormwater runoff. Streamflow in the area is highly influenced by groundwater and not by direct outflows of treated wastewater. This dataset contains stream site information (CapeCodStreams_SiteInfo.csv), field and laboratory observations (CapeCodStreams_Field_Lab_QW.csv), and information on streamflow and calculated nitrogen loads (CapeCodStreams_Flow_and_Loads.csv). Additionally, the dataset provides information on simulated groundwater recharge areas contributing to individual stream reaches. Recharge area characteristics, including size, recharge quantity, groundwater travel time, nitrogen-yield characteristics, and land-use classifications, are provided (CapeCodStreams_RA_Char.csv and CapeCodStreams_RA_Wshed_Load.csv). A data dictionary (CapeCodStreams_Data_Dictionary.csv) is provided to describe column attributes and define attribute units.
