How does holding-time tracking work?

Each analysis's holding time is configured per test (defaults follow EPA Part 136 Table II). The clock anchors to collection date/time, and Aliquora shows a countdown, raises approaching-expiry alerts, and flags analyses run past their holding time.

Which EDD formats do you support?

Aliquora exports EDDs formatted for EQuIS and GeoTracker submissions, plus generic CSV for state systems that accept spreadsheet uploads.

Can field crews log samples before they reach the lab?

Yes. Samples can be registered at collection with location and custody details, and the chain-of-custody record tracks every transfer until receipt at the lab.

Do you support compositing and permit-specific limits?

Sample submission forms are configurable per project, including composite fields, and result limits are configured per test definition — so each permit or program can carry its own spec set.

Water & Wastewater Laboratories

Drinking water and wastewater labs live by holding times, chain of custody, and regulator-ready reporting. Aliquora tracks EPA Part 136 holding times automatically and exports EDDs for your compliance submissions.

How it works

A typical water & wastewater workflow in Aliquora

1

Log collection and custody

Record collection date/time, sampling location, and custody transfers. The chain-of-custody record follows the samples from the field to the bench.
2

Holding-time clocks start automatically

Aliquora computes each analysis's holding time from collection per EPA Part 136 and shows a live countdown, so BOD and microbiology never quietly expire on the dock.
3

Analyze with method QC

Run samples in QC batches with blanks, duplicates, and spikes. Control charts evaluate recovery trends against Westgard rules and alert on drift.
4

Review against limits

Results are compared to configured MCLs or permit limits, with out-of-spec values flagged for documented review before release.
5

Export the EDD

Generate an electronic data deliverable formatted for EQuIS or GeoTracker, plus branded PDF reports for municipalities and permit holders.

Aliquora's holding-time tracking follows 40 CFR Part 136 Table II, and its audit trail documents who collected, received, analyzed, and approved every result — supporting NELAP/TNI and state drinking-water certification programs.
