Analysis

What to know about Somerville's water

Somerville ranks #728 out of 1067 cities in Texas for water quality, placing it below average in the state.

Somerville relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Hexavalent chromium (chromium-6) was detected at 0.03 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

As a small community water system, Somerville may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 9 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
