What you get
A current Title 22 sampling plan and monitoring schedule, your bacteriological sample siting plan, documented collection with chain-of-custody records, and results coordinated and reported on the regulatory timeline.
Regulatory Compliance
Drinking Water Sampling Services for California Water Systems
Sampling plans, monitoring schedules, and field collection for California public water systems: the right samples, from the right sites, delivered to a certified laboratory on time.
Who it is for: Systems that carry monitoring duties they cannot cleanly staff: small community water systems, mutual water companies, noncommunity systems, and districts whose certified operators already carry operations and reporting.
Overview
Exodus provides water sampling services for California public water systems, covering both halves of the work: the sampling plans and monitoring schedules your program runs on, and the field collection that gets samples to a certified laboratory on time. Drinking water sampling is scheduled work with fixed regulatory deadlines, and it is where a compliance program most often slips.
The plans come from the Title 22 monitoring requirements for your system type, sources, and treatment. The collection follows the plan: sampling sites worked on schedule, chain-of-custody documentation with every set, results coordinated back to you, and reporting deadlines tracked so nothing is filed late.
What we do
Sampling Plans & Monitoring Schedules
Title 22 monitoring plans and schedules, including your bacteriological sample siting plan.
More detail
Every monitoring duty your system carries, routine and triggered, is gathered into one Title 22 plan: what is sampled, where, how often, and by when. That includes the bacteriological sample siting plan, the source and distribution monitoring schedules, and the calendar that ties sampling dates to reporting deadlines.
Plans are revisited as your system changes. A new source, a treatment change, or a requirement that arrives mid-cycle is worked into the plan, so the document DDW holds matches the sampling your system actually performs.
Sampling Collection & Coordination
Collection and delivery of compliance samples to certified laboratories, with results coordination.
Coliform, Lead and Copper, and DBP Sampling
Under the Revised Total Coliform Rule, community systems sample the distribution system monthly. Coliform sampling follows your bacteriological sample siting plan, at the sites and frequency your system size requires, with repeat sampling worked in when a result calls for it.
Lead and copper sampling runs on its own schedule at the sites identified through your service line inventory work. Disinfection byproduct sampling, source monitoring, and the rest of your Title 22 monitoring are carried on the same calendar, so no program is tracked in a separate place by a different person.
Sampling locations are not interchangeable. Distribution sites are chosen to represent the water your customers actually receive, and lead and copper sites are chosen because they are the most likely to show a problem.
Field Collection, Chain of Custody, and Lab Coordination
Collection is field work, done by the same team that runs the plan. Samples are collected across your service area on the schedule the plan sets, with chain-of-custody documentation for every set, so each result can be traced from the sample tap to the laboratory report.
Samples go to certified laboratories, and the coordination does not stop at delivery. Results are tracked, checked against your reporting deadlines, and coordinated back to you, and a missed sample or an unexpected result is surfaced while there is still time to respond.
Do you write the sampling plan, collect the samples, or both?
Both. Exodus writes the Title 22 sampling plans and monitoring schedules, and the same program covers field collection and delivery to certified laboratories, with results coordination.
Which samples does a California system take every month?
Monthly distribution sampling for coliform bacteria under the Revised Total Coliform Rule is the standing monthly duty for community systems. The rest of your monitoring (lead and copper, disinfection byproducts, and source sampling) runs on the schedules in your plan.
What happens if a result comes back with a detection, or a sample is missed?
A missed sample can become a monitoring violation, and a detection can trigger repeat sampling, notifications, or corrective action. Because Exodus tracks the schedule and the results together, the response starts from the plan instead of from a surprise.
Can Exodus take over our sampling mid-year?
Yes. We review your current plan and completed monitoring, rebuild the schedule for the rest of the cycle, and pick up collection from the next round.
