Despite high public trust in Prosper’s drinking water, local water quality reports do not test for microplastics, an emerging contaminant increasingly linked to human health risks and environmental exposure nationwide.

Urgent Measures Proposed as Microplastic Pollution Threatens Global Health – One Green Planet 

Background on Prosper & Public Trust

Prosper, Texas is a suburban town near Dallas, and is known for its fast growth and safety, as the town has grown at two digit percentages each year for the past 5 years. Despite being famous for its safety and quality of life even within the suburbs in Texas, there still were problems that weren’t seen to the public, perhaps too small to be seen.  In order to maintain trust from the inhabitants, the government of Prosper has utilized diverse methods. One of them is clarity and being truthfull, as it is shown where the water quality reports are clearly published each year for the general public. The “obvious” pollutants; Arsenic, Lead, Nitrate, Chlorine, and other microorganism rates were precisely stated. However, after a close examination of the report, some major holes within the report were discovered. A major emerging pollutant, also known as microplastics were nowhere to be seen.

Missing Data from the Report

Microplastics are extremely small plastic particles measuring less than five millimeters in diameter, created through the breakdown of larger plastic waste or released directly from consumer products such as synthetic clothing, packaging, and personal care items. According to an observational study from the World Health Organization (WHO), microplastics have been detected in oceans, freshwater systems, food, and drinking water worldwide, raising growing concern among researchers and the general public. There have been multiple studies that linked microplastic presence within the body leading to increased occurrence of stroke, diabetes, and dementia. As such, microplastics are an important pollutant for the government to measure and incorporate in water reports annually.  

The Regulatory Gap in the United States

At the federal level, the United States currently has no legally binding standards or mandatory testing requirements for microplastics in drinking water due to lack of public acknowledgement.  The Environmental Protection Agency’s existing water quality regulations only focus on contaminants like heavy metals, organic chemicals, and microorganisms, but microplastics are not one of them. As a result, the absence of microplastics data in Prosper’s water shows a nationwide gap rather than a failure unique to the city. 

In contrast, there is a state that has taken action. California’s state water resources board, for example, has taken early steps to address this issue by formally defining microplastics and established guidelines for their monitoring and analysis, positioning the state ahead of the entire nation, and showing the significance of this emerging contaminant. 

Microplastics as a Blind Spot

 This gap highlights a broader issue in water quality oversight, especially in Texas. Microplastics is a part of that gap where it represents the rapidly increasing class of novel contaminants. It also highlights the importance of governments implementing policies to keep up with the new scientific findings. Yet, in Prosper and in many other communities, microplastics remain excluded from routine water testing. This gap can create the impression that drinking water is safe, when in reality, the unmeasured risks are threatening us daily. As a result, contaminants that are not tested for are unlikely to be discussed publicly. 

Addressing this data gap through early research and updated testing standards will play a critical role in protecting public health and maintaining long term trust with the public and the government.
