Drinking Water Watch (DWW) allows state drinking water administrators, laboratories, and the public to access drinking water information under the Freedom of Information Act (FOIA). It can be deployed on the World Wide Web outside a state's electronic firewall and does not require sign-in authentication for access. The database from which DWW retrieves its information is a static copy of the state’s custodial drinking water database, which is refreshed at the state’s discretion.
This search page lets you search the drinking water database for two broad categories of information: public water systems (inventory, sampling schedules, violations and enforcement actions) and sampling data reported for public water systems. All search field criteria on the Search Page are “and” criteria. That is, each field where you specify a search value should be interpreted as further constraining the search by “and”. You can enter search criteria anywhere on the page. The following are three example searches:
All water systems principally served by a specific county and their administrative contacts (specify Principal County Served and Point of Contact Type AC)
All TCR Sample Results that showed presence of Total Coliform bacteria for a specific Water System within the past 2 years (specify the Water System No. and select Sample Class TCR Samples Detection Only
All 90th percentile Lead and Copper sample summaries for Community water systems within the past 6 years (specify Water System Type C and select Sample Class Lead and Copper Summaries and enter today's date-minus 6 years in the Sample Collection Date Range From field and today's date in the To field.
(1) Public Water Systems
Public Water Supply Systems Search gives you search criteria so that you may easily find one or more public water systems. Water systems are classified according to rules developed by the U.S. Environmental Protection Agency (EPA) and each state.
You can enter criteria into one or more of the following six Public Water Supply systems Search Parameters:
Pressing Search for Water Systems displays the Water Systems List from which you can select to view additional information about the water system on the Water System Detail page including:
Points-of-Contact
Annual operating periods and population served
Service connections
Sources of water
Service areas
Water purchases
If your search includes a Point of Contact Type, the address information for the type of point of contact you specified is included as a column on the Water Systems List. Selecting a water system presents you the Water System Detail page, where you can view detailed inventory information about the Water System. You may also click on links for sampling, scheduling, site visit, and violation information for the water system you selected.
(2) Search for Samples
The Sample Collection Date Range fields let you further broaden or constrain the number of sample results your criteria retrieves. To prevent lengthy accidental searches, the sample search default will always return results for the most recent two years unless you explicitly enter a wider or narrower date range. If you remove the default dates, the search still uses the most recent two years as search criteria. To return results from more than two years ago, you need to enter a “from” date that is before two years ago. For example, if today’s date is June 9, 2005,
to find samples from the last 5 years, you would need to enter 6/9/2000 in the “from” date and 6/9/2005 in the “to” date of the search date range. To find samples from the last month.
to find samples from the last month, you would need to enter 5/10/2005 in the “from” date and 6/9/2005 in the “to” date of the search date range. To find samples from the last month.
If you specify one or more Sample Search Parameters criteria, the Search for Samples button is available.
