Find out if your building has a lead service line Water utilities keep an inventory of service-line materials. Ask Sonterra MUD whether your address is on it before you replace pipes.

Is this right for my home?
Choose your situation Your situation I live in an older building I care about PFAS My water tastes of chlorine I have scale or hard water I want the broadest reduction
Your path: I live in an older building Lead from plumbing is the main question Older buildings may have lead service lines, solder or fixtures. Sonterra Mud’s record shows lead at 0.431 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
Look for Lead reduction: NSF/ANSI 53 (lead)
How to test your tap →
Your path: I care about PFAS Check what was tested 4 of 29 PFAS tested were detected in Sonterra Mud’s record (PFBS 7 ng/L, PFHxA 6 ng/L and PFBA 6.9 ng/L, and more). If PFAS matters to you, a filter certification names each compound it covers.
Look for NSF/ANSI 53 or 58, with each compound you care about named on the listing
PFAS in Sonterra Mud →
Your path: My water tastes of chlorine The disinfectant is not in this record Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Look for NSF/ANSI 42 (chlorine taste and odor)
Water treatment technologies →
Your path: I have scale or hard water Hardness is not in this record Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Look for Softener: NSF/ANSI 44 (softeners)
Hard water explained →
Your path: I want the broadest reduction Reverse osmosis at one tap Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.
Look for NSF/ANSI 58

? One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes. Follow Sonterra Mud’s water → Is Sonterra Mud tap water safe to drink? + PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Sonterra Mud, PFAS were detected below their limits, and PFBA 6.9 ng/L and PFPeA 15.7 ng/L with no federal or state limit; the lead 90th-percentile result was 0.43 µg/L against the 15 µg/L action level; one health-based violation is on record (Fluoride). SONTERRA MUD (PWSID TX2460157) has a Purity Score of 98/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →
Who provides tap water in Sonterra Mud? + SONTERRA MUD (PWS ID TX2460157) is the public water system on record for Sonterra Mud, Texas, serving about 16,614 people. Confirm the utility on your water bill before acting on a specific finding. Water utility →

Are PFAS "forever chemicals" in Sonterra Mud's water? + In EPA's UCMR 5 testing (2024-04-23 to 2024-10-21), PFBS was detected at 7 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 6 ng/L, below the 400,000 ng/L state limit. PFBA (6.9 ng/L) and PFPeA (15.7 ng/L) were also detected; they have no federal or state limit. What we found →
Is there lead in Sonterra Mud's tap water? + SONTERRA MUD's most recent lead 90th-percentile result (2022–2024) was 0.43 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink. Your household →

Methodology: how we analyze water . Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Methodology
How PurityMap reads Sonterra Mud’s water 01 Source data EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
02 Normalize Units converted to one basis; a non-detect kept distinct from zero.
03 Classify Each result tagged by reference type: MCL, action level, screening level or aesthetic.
04 Compare to the named reference Every value sits against its own reference, never a blended one.
05 Score Measured subjects summarised at the water-system level; an open health-based violation caps the score.
06 Match treatment Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. SONTERRA MUD · PWSID TX2460157 · Purity Score 98/100 (Excellent) · Confidence: moderate · Assessed at the water-system level
