Closing day gives you the keys, but the water history of your new St. Charles County home is often in the papers you signed, the files the seller kept, and the account records that move into your name. Gathering those items in the first month makes every later decision easier, from testing to treatment to calling a service provider.
Start With the Water Source
Find out first whether the home runs on a public supply or a private well. That answer decides which records matter. A home on public water has a utility account, and the account history shows billing dates, meter readings, and service history. A home on a private well has a different set of records, and they are easier to lose because they often sit in a drawer or a previous owner's inbox.
Records to Request From the Seller
Ask the seller, or the listing agent, for the items below. If an item does not exist, write that down too. A missing record is useful information.
- Well completion or construction records, if the home has a well. These usually list the well depth, the casing, and the date it was drilled.
- Pump and pressure tank information, including the make, model, and year installed.
- Past water test results, with the lab name, sample date, and the list of items tested.
- Manuals and warranty papers for softeners, filters, UV units, or other treatment equipment.
- Service invoices showing when filters were changed, when salt was added, and who did the work.
- Notes on past problems, such as staining, odor, low pressure, or outages.
- For public water, a recent bill, the meter location, and instructions for moving the service account into your name.
Check Public Records in St. Charles County
Some information sits outside the seller's files. Well permits and well logs for properties in St. Charles County may be held by state or county agencies, and you can ask whether a record exists for your address. For public water, the supplying utility can confirm the service area, the account transfer steps, and whether its published water quality reports cover your street. Ask these questions in writing so you have a record of the answers.
Read the Disclosure for Water Items
Your sale documents may include a disclosure about the water system, the well, or past issues. Read it with a highlighter. Note any statement about water testing, equipment that stays with the house, or repairs. If a line is unclear, ask the seller or your agent what it means. Also ask whether any equipment is leased, because leased units often carry a separate account and return steps.
Build a Simple Water File
Put everything in one folder, paper or digital. Label it with the address and the date you received each item. Add a short list on the front page with the water source, the meter or well location, the main shutoff, the equipment that came with the house, and the name of the person who handled the last service visit. Keep your copies with the home documents, not in an email thread you might lose.
Decide What to Test Once You Know the Source
Records tell you what was done, but they do not tell you what is in your water today. Once you know the source, decide which tests to request. A certified lab can run tests for specific substances, and sample containers, timing, and handling differ by test, so ask the lab what it needs before you collect a sample. A test result reports what the sample contains. Interpreting that result for health is a question for the lab or a local health agency. Keep each result in your water file so a later reading can be compared with an earlier one.
Your First Month Checklist
- Confirm your water source and the agency or utility you contact about it.
- Request the records listed above, and write down which ones were not provided.
- If the home is on public water, transfer or open the account in your name.
- Label the shutoffs, the meter, and any treatment equipment.
- Review the equipment manuals and note any service schedule.
- Choose tests that match your source and any concerns raised in the disclosure.
If something in the file conflicts or seems unclear, have a licensed professional in your area look at the system on site. Bring the file with you, since a complete record lets anyone who visits the home start from facts instead of guesses.
