A property near Poolvile · Parker County, TX
Nothing measured in the water around this address is above a federal HEALTH limit for drinking water. Arsenic was never measured near here, so this page cannot speak to that.
| soft | slightly | moderate | hard | very hard |
Based on the median of tested wells in the same ~7-mile grid square (Texas Water Development Board — Groundwater Database (GWDB)). This describes the groundwater around this property — it is not a test of this well.
| Hardness removed per day | 7,358 grains |
| Suggested size | 64,000 grain |
| Regeneration | about every 9 days |
| Salt use per year | 767 lb · ~19 bags |
| Hardness minerals through the plumbing per year | 384 lb |
| Sodium a softener adds | ~257 mg/L |
Assumes 3 people using 75 gallons each per day (225 gal/day) — adjust for the actual household. A softener exchanges hardness for sodium; at this hardness that is a lot, so potassium chloride or a reverse-osmosis tap for drinking water is worth discussing.
Bars run to 1.5× each limit; the tick is the limit itself. Medians of tested wells in the same ~7-mile grid square, based on 15 measurements from 9 separate wells. The EPA sets no hardness limit — that one is the Water Quality Association's "hard" boundary, the industry convention.
| Well depth | 220 ft |
| Tested yield | 9 gal/min |
| Well completed | 2026-09-22 |
Every chemistry figure on this page is the median of 15 laboratory measurements from 9 separate wells in the same ~7-mile grid square collected between 1949 and 1999, taken from Texas Water Development Board — Groundwater Database (GWDB) — a public dataset of water-quality samples from wells across Texas, published as bulk files and updated nightly. We publish a figure for a location only when at least 3 separate wells nearby have been tested; below that we show nothing rather than estimate.
Depth, yield and completion date come from the record filed with the state for this property, published by Texas Water Development Board — Submitted Driller’s Reports (SDR) — Texas licensed drillers must file a report for every well they complete, within 60 days.
Where this page says a reading is high, it is compared against the published US EPA National Primary Drinking Water Regulations (health-based limits) and Secondary Drinking Water Standards (taste, odour and staining).
Hardness is the exception: the EPA sets no limit for it at all. The point where a softener becomes the usual recommendation (7 grains per gallon) is the Water Quality Association’s “hard” classification, the industry convention. Either way, we set no thresholds of our own.
We did not measure, model, estimate or predict anything. No machine learning, no AI, and no attempt to infer what is in this particular well. We took published government measurements from wells near this address, took the middle value (the median), and compared it to published EPA limits. That is the whole calculation, and the same arithmetic on the same public files gives the same answer.
What this is not: a test of this well. Groundwater varies from property to property, and these readings describe the area, not this household’s tap. Nothing here is a statement about whether this water is safe to drink. Only a laboratory test of a sample from this property can tell you what is actually in it.

This is the public sample. The street address and the direct link to this well’s filed state report are withheld here. Both appear on every copy a dealer receives — the link opens the record on the state’s own site, so the reader can check the depth, yield and completion date without taking anyone’s word for them.
