• Request your utility's CCR (Consumer Confidence Report) - your water provider must publish this annually
• Check your ZIP code - each area in Lubbock has different water systems and risk levels

Filter Your Water

• NSF-certified pitcher filter removes chlorine taste and some contaminants ($20–40)
• NSF 53-certified filter for lead - recommended for homes built before 1986
• Reverse osmosis system removes 95%+ of contaminants including lead, PFAS, and nitrates ($150–400)

Test for Radon

• Lubbock is in a moderate-risk radon area
• Short-term radon test kits cost $10–25
• If levels exceed 4 pCi/L, EPA recommends professional mitigation

Housing Age Profile

Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 1980, much of Lubbock's housing falls on the safer side of that line - though homes built before 1986 still warrant testing regardless of the city-wide profile.

Pre-1970 (Lead Pipes Risk)

Most homes in Lubbock were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Lubbock

0.0014

mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Lead risk in Lubbock appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Flood & Climate Risk in Lubbock

Taken together, Lubbock's 341 NFIP flood insurance claims and 0% FEMA flood zone coverage place it in the moderate range of exposure. That middle position has specific implications for water quality. The contamination pathways that flooding can open - surface water overwhelming treatment facility intake, floodwaters infiltrating private wells, distribution pressure changes creating backflow - are not constant risks in a moderate-exposure community. But they do become active during significant flood events, and the claim record here indicates enough of those events to make flood timing an occasional factor in local water quality conversations.

Total FEMA Flood Claims

~17

Est. Claims/Year

Lubbock has a moderate flood history with 341 FEMA claims. Flood events can contaminate drinking water and overwhelm treatment systems.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure.

Residents in flood-prone areas should consider flood insurance even outside FEMA zones - over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
