What is the infrastructure stress indicator?

The infrastructure stress indicator is a heuristic 0-100 composite of housing age, state funding need, violation history, and lead evidence. It is not a probability, measured pipe condition, or forecast of breaks, pressure loss, or contamination. Bettles Field's average indicator is 64/100.

Infrastructure Risk Distribution

Bettles Field is covered by a single ZIP code. Its infrastructure risk level:

Infrastructure Risk Overview

Bettles Field, Alaska has a very-high modeled infrastructure stress level with an average heuristic indicator of 64/100. It is an evidence summary, not a probability.

The infrastructure stress indicator combines source inputs for housing age, funding need, violation history, and lead evidence. It does not measure the likelihood of pipe failure, water-main breaks, or system degradation.

Infrastructure Risk Distribution

How Bettles Field's 1 ZIP code is distributed by infrastructure risk level:

100% of Bettles Field's ZIP codes are in the high or very-high modeled stress category. This is a distribution of heuristic inputs, not a failure forecast.

Water System Age and Pipe Materials

The median home in Bettles Field was built in 1987 (approximately 39 years old). Housing age is one of the strongest proxies for water infrastructure age, as service lines and interior plumbing were typically installed during construction.

Pipe material risks by era:

With 62% of Bettles Field's homes built before 1986, a significant portion of residential plumbing may contain lead solder or aging pipe materials.

Carbon Monoxide & Gas Safety

The available county record contains no CO/gas incidents. The average CO risk score is 0 out of 100.

Carbon monoxide is odorless and colorless - it is the leading cause of poisoning deaths in the U.S. Risk factors include:

• Gas furnaces, water heaters, and stoves
• Attached garages
• Blocked chimneys or vents
• Portable generators used indoors

Prevention:

• Install CO detectors on every level, especially near bedrooms
• Have gas appliances inspected annually
• Never run generators, grills, or cars in enclosed spaces
• Replace CO detectors every 5-7 years

What Homeowners Can Do

Pipe Inspection

• Hire a licensed plumber to inspect your service line and interior plumbing
• Check for discolored water (brown/orange = rust; white/cloudy = air or sediment)
• Test water pressure - low pressure may indicate buildup in aging pipes
• Look for visible corrosion on exposed pipes in basement or utility areas

Water Heater Maintenance

• Flush your water heater annually to remove sediment
• Check the anode rod every 2-3 years (prevents tank corrosion)
• Set temperature to 120F to prevent scalding and reduce energy use
• Replace water heaters older than 10-15 years proactively

CO Detector Placement

• One detector per floor, minimum
• Within 10 feet of each bedroom door
• Near attached garage and utility room
• 5 feet above the floor (CO rises with warm air) or on the ceiling
• Not near windows, doors, or HVAC vents (air movement causes false readings)
