NCCA 2010 Sediment Indicator Status Metadata		
		
Revised 06.21.2016		
		
"For questions about these data, please contact Hugh Sullivan at sullivan.hugh@epa.gov or use the Contact Us link on the webpage: http://www.epa.gov/national-aquatic-resource-surveys/forms/national-aquatic-resource-surveys-contact-us"		
"It is the responsibility of the end data user to become familiar with the QA codes used in the NCCA 2010 assessment (NCCA_QA_Codes.csv) and review the ""QA_CODES"" column in each dataset to determine whether the data meet quality objectives for specific uses."		
Location information for each site is contained in the SITEINFO File. Use UID as key column for merging data.		
		
VARIABLE		DESCRIPTION

NEP_NM		Name of National Estuary Program study area within which site is located area (if applicable)
EPA_REG		Identifies EPA Region within which the site is located
STATUS_ALL		Status of sampling at that site.  
TNT_ALL		Target or not Target for sampling

ERM_TOT		Num. Analytes with concentrations > ERM
LRM_STATUS		LRM Status (based on pr_max)
MERMQ		Mean ERM-Q
MERMQ_STATUS		Mean ERM-Q Status
MPECQ		Mean PECQ value

NCA_SQI_STATUS		NCA Sediment Quality Index Status
NCA_SQI_STATUS_NOTOC		"NCA Sediment Quality Index Status, excluding TOC"
NCA_TOX_STATUS		NCA Sediment Toxicity Status
NCCA_SCI_STATUS		NCCA Sediment Chemistry Index Status
NCCA_SQI_STATUS		NCCA Sediment Quality Index Status
PEC_STATUS		Mean PECQ status
PR_MAX		Maximum probability of observing toxicity in the sample (LRM)
SIG_TEST		Significance of mean Test Survival compared to mean Control survival (Yes=test was sig. diff. from control; No=test was not sig. diff. from control)
TOC		Total Organic Carbon (%)
TOC_STATUS		NCA TOC Status
TOC_UNITS		Units - Total organic carbon

"Date: June 21, 2016: Filename changed from ncca2010_sediment_indicator_status.csv to ncca2010_sediment_indicator_status.06.21.2016.csv"		
		
"Date: June 21, 2016: Change to file ncca2010_sediment_indicator_status.06.21.2016.csv: assessment results and Good-Fair-Poor-Missing status updated. The report was published based upon these updated values so there is no change to the assessments published in the report."
