Questions this profile can answer

What is the current outdoor air quality near Houston?

The current AirNow AQI for the Houston-Galveston-Brazoria reporting area is 80 (Moderate), observed 10/15/26 10:00 CDT.

AirNow data are preliminary outdoor observations and can change quickly. They are not a measurement of indoor air and are not used in the long-term index.

What do EPA records say about drinking-water systems?

Across active community water systems in Texas, 93.4% had no current health-based violation in the ECHO query: 315 of 4760 systems were returned with one.

This is state-level regulatory context. It does not establish which utility serves an address, whether a violation affected a specific tap, or whether water is unsafe today.

How strong is warm-season moisture pressure?

The selected NOAA normals station has a HomeNHealthy warm-season moisture-pressure value of 88.0 out of 100, based on a May–September mean of 82.3°F and 25.3 inches of precipitation.

Monthly precipitation normals, January through December. Station: USC00414326 — HOUSTON-PORT (5.5 mi).

How old is the housing stock?

The ACS median year built is 1982. An estimated 47.0% of units in the Census age table were built before 1980, and 4.0% before 1940.

The Census groups 1970–1979 together. HomeNHealthy therefore reports the observable pre-1980 share rather than estimating an exact pre-1978 lead-paint-era percentage.

What should a homeowner verify at the property?

Geographic data cannot determine conditions inside a building. Depending on the property, direct checks may include radon testing, carbon-monoxide alarms, indoor humidity, visible moisture, lead evaluation for older materials, and the serving water utility’s current Consumer Confidence Report.
