Title
Ambient and fixed station network groundwater monitoring point data (1985 - 1998) {1999}
Description
This coverage represents the point locations and data for 1,106 groundwater
quality monitoring points sampled under the PA DEP Fixed Station
Network (FSN) and Ambient Survey groundwater monitoring program.
Sample data were collected from August 1985 to December 1998. Monitoring
points were typically homeowner wells, springs, public water supplies, or industrial
wells. Locations were chosen to represent regional background conditions
within a groundwater basin. Samples were collected by prioritized
groundwater basins. Monitoring points represent some of the top 100
priority basins of the 478 groundwater basins. Monitoring points were
analyzed for 27 different analytes including pH, alkalinity, total dissolved
solids, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, phosphorus,
total organic carbon, total hardness, calcium, magnesium, sodium,
potassium, chloride, sulfate, silica, arsenic, barium, cadmium, chromium,
copper, iron, lead, manganese, zinc, mercury, and turbidity. Data for
alkalinity through silica are in mg/L, whereas values listed for arsenic
through mercury are in ug/L. Turbidity is in NTUs. PH is a laboratory pH value.
Analyte values listed with the coverage are means. Monitoring points have been
sampled up to 34 times. Trend analysis results are included for 474 monitoring
points by parameter. The Kendall Tau rank correlation test was used to test for trends
in ground water quality over time. This test is a nonparametric procedure that is
similar to the standard correlation coefficient to assess the presence of a relationship
between variables. The Kendall Tau value represents a probability that there is a
relationship between two variables. A significance level of .05 was used with the
calculated Kendall Tau correlation coefficients. Trend analysis was performed on
monitoring points using SAS statistical software.
