Homeowners in The Highlands community of Porter, Texas, are expressing frustration over persistent black sediment appearing in their water, bathtubs, toilet bowls, and filters. Despite assurances from Montgomery County Municipal Utility District No. 140 that the water meets all Texas drinking water standards and that the sediment is due to naturally occurring manganese in the groundwater, residents remain concerned about the safety of their water for drinking, bathing, and household use. Many have installed filtration systems or switched to bottled water, but the problem persists, leading to ongoing discomfort and calls for clearer explanations and solutions. Local authorities and the Texas Commission on Environmental Quality have been contacted for further information and guidance.
