Description:
Abstract:
These are water quality monitoring data from a long term fixed location monitoring study of stations located in the Chesapeake Bay and Ohio River watersheds. The data are collected from fifty-six stations for a time period beginning January 1986 and extending to the present. Fifty-five of the stations are in non-tidal waters. One station (XGG8251) is in tidal waters.
Purpose:
The Maryland Department of Natural Resources Section 106 Ambient Water Quality Monitoring Program (CORE\Trend) is part of a cooperative effort between the Federal government and State and local governments in the Chesapeake Bay watershed to assess the status and trends of nutrient and sediment concentrations in Maryland's waters.
The information is integrated with data from other Chesapeake Bay water quality stations and living resources monitoring projects and used to understand linkages, temporal variation and long-term trends.
Water quality data are used to refine, calibrate and validate Chesapeake Bay ecological models. The models are used to develop and assess water quality criteria with the goal of removing the Chesapeake Bay and its rivers from the list of impaired waters.

Supplemental_Information:
Two reports contain information that should be considered when CORE/Trend data are used for data analysis. The reports are named: DAITS 043: Comparability of parameter estimates from whole water and filtered samples for MD Department of Health and Mental Hygiene data (June 2006, revised April 2009) and DAITS 046: Comparison of chlorophyll and pheophytin analyzed at DHMH and CBL (May 2009). Copies of the reports may be downloaded. <http://www.chesapeakebay.net/documents/Completed_DAITS_as_of_9-21-10.pdf>.

Attribute_Accuracy_Report:
QUALITY ASSURANCE/QUALITY CONTROL Maryland Department of Natural Resources followed specific procedures to ensure that the Tributary component of the Chesapeake Bay Water Quality Monitoring Program design was properly implemented and managed with sufficient accuracy, precision and detection limits. Accuracy (closeness to the true value) of collected data was controlled and assured by proper use, calibration and maintenance of both field and laboratory equipment for the measurement of physical and chemical parameters.
The procedures to control and assure the accuracy of field measurements involved the calibration of field instruments, the verification of calibrations, and equipment maintenance. Most of the details of how data acquired with YSI sondes and Hydrolab sondes were quality assured and quality controlled are described in the process description elements in the Lineage portion of this metadata record.
Daily quality control checks which included the running of blanks and standards were used to control and assure laboratory accuracy.
Accuracy of Chesapeake Biological Laboratory, Nutrient Analytical Services Laboratory (CBL NASL) and Maryland Department of Health and Mental Hygiene (DHMH) results was also assessed through DNR's participation in the Chesapeake Bay Coordinated Split Sample Program (CSSP) a split sampling program in which five laboratories involved in Chesapeake Bay monitoring analyze the coordinated split samples. CSSP was established in June 1989 to establish a measure of comparability between sampling and analytical operations for water quality monitoring throughout the Chesapeake Bay and its tributaries. DNR followed the protocols in the Chesapeake Bay Coordinated Split Sample Program Implementation Guidelines (EPA 1991) and its revisions. Split samples were collected quarterly. Results were analyzed by appropriate statistical methods to determine if results differed significantly among labs. If a difference occurred, discussions began regarding techniques and potential methods changes to resolve discrepancies.
January 2014: Rain preceding sampling was noted at stations: CB1.0 (SUS0109), DER0015 and GUN0475. Rain during sampling was observed at stations: MON0269 and POT1830. The high creek level was attributed to rain the previous weekend at station PIS0033. Debris was observed against the center arches of the station CON0005 bridge. Goose scat was notated around the station CON0180 sampling location. Rains during the night preceding sampling, as well as, heavy rain during sampling, was noted at stations: POT1472, POT1595 and POT1596. The station POT1596 comment characterized the river as muddy.

Station POT1830 samples were collected from the C&O Park in Maryland. Station GE0009 ion matrix samples were collected at Creekside Park and station NBP0326 ion matrix samples were collected from the bank, upstream of the bridge. Samples of station MON0155 water were collected from the bridge. The station XGG8251 sample was collected from the bulkhead by the boat ramp. Stations POT1472 and POT1595 were sampled later in the month than normal because they were inaccessible earlier.
February 2014: Samples at station GEO0009 were collected using a bucket. Station NBP0326 and station POT2766 samples were both collected upstream of the bridges. At station TOW0030 the sample was collected at a small, unfrozen opening in the ice downstream of the bridge. Similarly, since the North side of the station XGG8251 was ice covered, the sample was collected from the drawbridge. Water samples from station POT2386 were collected from the boat ramp.
March 2014: The station WIL0013 ion matrix sample was collected from the river’s edge upstream of the convergence with Braddock Run.

VERIFICATION AND DATA MANAGEMENT
Each month DNR Tawes Office and Field Office personnel conducted data QA/QC procedures. All of the water quality calibration "grab" sample data were plotted. Outliers and anomalous values were thoroughly researched. Staff compared unusual values to historic values from the site and values from nearby sites. Weather events were considered, event logs were reviewed and DHMH and CBL analytical laboratory staff and DNR field staff members were consulted regarding possible legitimate causes for outlying values. In cases where values were not considered to be legitimate, they were masked from the published dataset with the approval of the field staff and the Quality Assurance Officer.
