Description:
Abstract:
The physical/chemical component of the Maryland Chesapeake Bay Water Quality Monitoring Program consists of water quality monitoring data collected at seventy tributary stations. Samples at all tributary stations are collected monthly.
This program assesses the water quality by evaluating the levels of nutrients and closely related habitat impacts such as dissolved oxygen and water clarity. One of the main goals of the Chesapeake Bay restoration is to reduce the impacts of excess nutrients on the Bay and its tributaries and these measurements provide some of the most direct linkages to management programs that are achieving this goal. The Chesapeake Bay Program jurisdictions have agreed to reduce nitrogen, phosphorus and sediment pollution to the Bay.
Purpose:
The Maryland Department of Natural Resources Chesapeake Bay Water Quality Monitoring Program 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 Chesapeake Bay mainstem and its tidal tributaries.
The information is integrated with data from other 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 tidal rivers from the list of impaired waters.

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) 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 2011- The data sonde hit the bottom at station LE1.2 and a field sheet comment indicated depth readings were off a bit. Another field sheet comment made at station NBP0461 noted that bridge construction was still ongoing and that the water was tinted orange. At station XGG8251it was noted that the Secchi disk depth was greater than the water depth at dock and that the Secchi measurement was not made from the bridge. Bottom and below-pycnocline water samples at station EE2.1were collected out of the same bottle.
February 2011- No known issues.
March 2011 - Orange colored filtration pads were noted at station NBP0689.
April 2011 - No known issues.
May 2011 - A field sheet comment at station NBP0689 noted that the filter pads were orange. At station ET4.1 it was stated that water column readings were taken from the water samples because the sonde cable was too short.
June 2011 - At station CCR0001 field sheet comments noted that the lake was backed up into the creek and that the water was orange colored. At station ET10.1, lack of rain for the previous two months and that a second sonde also read 1.6 PPT was noted. Dead fish were seen in the river near station ET4.1.
July 2011 - At station XFB1986 a comment observed that the surface water column readings were double checked using Hydrolab meter B. At station CCR0001 field sheet comments noted that the lake was backed up into the creek and that the water was orange colored. Very orange murky water was notated at station GEO0009. An algae scum on the water was noted at station ET3.1 and dissolved oxygen and pH readings were double checked using a second data sonde.
August 2011 - A comment at station ET6.1 indicted that the alpha bottle had broken from the cable and that a weighted bottle was used when the bottom sample was collected. At station ANA0082 it was noted that the water contained either an algal bloom or a sediment load. At station WT1.1 it was noted that the surface pH was questionable. Meter scoping due to current was noted at station ET10.1.

Heavy rain during the week befor sampling was noted at stations MAT0016, RET2.1, RET2.4, TF2.1, TF2.2, TF2.4 and XFB1986. Construction on the bridge was noted at station ET4.1 and construction on the shoreline was noted at station MAT0016. The 7.0m dissolved oxygen reading was double checked at station WT7.1.
October 2011 - At station MAT0078 it was observed that dissolved oxygen readings using meter Q were unstable and that the value of a reading taken with meter T was 8.9 mg/l. A very high water level due to high winds was noted at station ET3.1. Stations NBP0326 and NBP0461 both had comments about rain preceding sampling and felled trees on the stream bank.
November 2011 - At station CCR0001 it was remarked that pH readings dropped very slowly and that fifteen minutes elapsed before the reading was recorded. Dark orange water color and discharge from a reservoir pipe was noted at station GEO0009. Light, chalky colored run off from a drain pipe just downstream from the bridge was noted at station LYO0004. It was remarked at station NBP0461 that a large area of the river was filled in by gravel and fill upstream of the sampling area.
December 2011 - A field sheet comment made at station CCR0001 noted that pH started at 8.2 and slowly dropped to 7.5. Bridge work on the downstream side of the bridge was noted at station MAT0078. Current at station EE2.2 caused the data sonde meter to scope. An oily sheen was observed on the water at station XDJ9007.

SONDE CALIBRATION and POST-CALIBRATION
The Yellow Springs Instrument (YSI) 6000 data sondes and HydroLabs were maintained and calibrated before and after each cruise in accordance with manufacturer's recommendations.
HYDROLAB PROFILE SAMPLING PROTOCOLS:
A profile of temperature, specific conductance, dissolved oxygen, and pH was obtained from the water column at 0.5 m, 1.0 m, 2.0 m and 3.0 m depth intervals below the surface. Thereafter readings were taken at 2.0 m intervals and at the bottom. Tributary bottom equals total depth minus one meter (not rounded). If the change in dissolved oxygen exceeded 1.0 mg/L or if the change in specific conductance equaled or exceeded 1,000 micromhos/cm over any 2.0 m interval, readings were taken at 1.0 m intervals between these two readings. For total depths less than or equal to 10.0 m, readings were taken at 1.0 m intervals.
GRAB SAMPLING DEPTH PROTOCOLS:
At stations where two depths were sampled, collections were taken at 0.5 m below the surface, and 1.0 m above the bottom. If the station total depth was equal to 1.5 m, the bottom sample was also collected at 0.5 m. Great caution was exercised when taking bottom samples; if the bottom was disturbed and bottom sediments appeared to have been included, the sample was dumped out and collected after the sediments had settled. Alternately, the sample was collected slightly higher in the water column and the new bottom sample depth was noted.
At stations where 4 depths were sampled and a pycnocline existed, collections were taken at 0.5 m below the surface, 1.5 m above the upper boundary of the pycnocline, 1.5 m below the lower boundary of the pycnocline, and 1.0 m above the bottom.
At stations where 4 depths were sampled and there was no discernable pycnocline, samples were taken at 0.5 m below the surface, at the closest profile depth one third the distance from the surface to the bottom, at the closest profile depth two thirds the distance from the surface to the bottom, and 1.0 m above the bottom.
SECCHI DEPTH:
Water transparency was determined, to the nearest 0.1 m using a 20-cm standard Secchi disc lowered into the water column with a calibrated rope. Observations were made on the shady side of the sampling location.

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 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.
