Data validation
ESdat is able to produce a Chemical Quality Assurance Report summarising the following QA checks and flagging any potential issues:
Field QA
-
Field duplicates and triplicates (Relative Percent Difference (RPD) values)
-
Field blanks, trip blanks, rinsates
-
Trip spikes
Lab QA
-
Lab duplicates (RPD values)
-
Holding times
-
Inorganic logic checks (Ionic balance, TDS>Na+Cl, COD>BOD, etc.)
-
Lab control samples/reference materials
-
Matrix spikes
-
Surrogates
Data analysis
Graphing
A graph may be produced for any time-series data. Graphing features will enable you to analyse and present your data via:
-
trend analysis including Mann Kendal or Linear Regression;
-
annotating the graph (TUp, TDn, and LH stand for Trending Up/Down, Last value Highest);
-
producing your graphs in Excel (can be edited like any other Excel chart);
-
saving and opting to automatically update when opening in Excel;
-
displaying compliance levels; and
-
customisable templates.

Comparing with environmental guidelines/compliance levels
Environmental Standards, and exceedances can be shown and flagged on all the ESdat outputs, including chemistry output tables, graphs, and maps. ESdat comes pre-loaded with most regulatory guidelines and users can add their own site-specific or other guidelines as required.
Tabulating
Chemistry Tables are rapidly generated and exported to Excel. Users are able to specify:
- compound orientation & grouping;
- environmental standards to be included;
- customisable exceedance formatting;
- statistical output;
- templates; and
- other settings.
