Ensuring Public Health and Compliance: The Critical Role of Water Quality Monitoring

Access to clean, safe water is necessary to sustain life, support public health, and promote environmental integrity. In a world where industries continue to grow yet natural resources are under constant stress thanks to climate change and a shifting global water cycle, water quality monitoring has emerged as an integral process to safeguard our communities. 

Today, we’re exploring the importance of water quality monitoring, its role in maintaining compliance, and how technology can play a role in future monitoring efforts.

Why Water Quality Monitoring Matters

Water quality monitoring is essential for a variety of reasons, including:

  • Public Health and Community Well-being. Waterborne diseases, contaminants, and pollutants can pose severe risks to public health. Regular water quality monitoring ensures that water sources meet established standards and regulations. These assessments help prevent outbreaks of waterborne illnesses, ensuring the well-being of communities.
  • Environmental Protection. Bodies of water are home to diverse ecosystems, and they play a pivotal role in maintaining ecological balance. Monitoring water quality helps protect aquatic life by identifying threats such as chemical pollutants, excessive nutrients, and temperature variations. It also helps mitigate the harmful effects of water pollution on rivers, lakes, and oceans, preserving biodiversity and ecosystem health.
  • Agricultural Sustainability. Agriculture is a vital industry, providing food for billions of people. However, it can also be a source of water pollution if fertilizers and pesticides used on crops enter water sources. Water quality monitoring in agricultural regions helps ensure that farm runoff does not contaminate nearby water bodies. It also enables modern farmers to adopt sustainable best practices that minimize their impact on water quality.

The Role of Water Quality Monitoring in Compliance

Water quality monitoring plays two essential roles in compliance. The first is Regulatory Compliance. In the USA, the Environmental Protection Agency (the EPA) and state-level agencies establish and enforce water quality standards. These standards dictate acceptable levels of various contaminants, including heavy metals, pathogens, and chemical compounds. Comprehensive water quality monitoring ensures that water systems, both public and private, comply with these regulations.

It also plays a vital role in Data Validation. Accurate and consistent data is critical for demonstrating compliance with water quality standards. Water quality monitoring provides the necessary data to validate compliance, ensuring that water treatment facilities and industrial processes meet the required quality criteria. It also assists in identifying and addressing non-compliance issues promptly.

Challenges in Water Quality Monitoring

While water quality monitoring is essential, several industries face unique challenges in meeting compliance standards.


Agricultural runoff can introduce nutrients, pesticides, and sediment into water bodies, affecting water quality. In addition, monitoring in rural areas can be challenging due to the vast and fragmented nature of farming operations.


Industrial processes can release pollutants into water sources, including heavy metals, chemicals, and thermal discharges. Compliance monitoring in manufacturing often requires continuous data collection and sophisticated instrumentation.


Public water treatment facilities must consistently meet stringent quality standards. Aging infrastructure, budget constraints, and the need for real-time data can make compliance monitoring complex for municipalities.

Government Regulations and Water Quality

The United States has established robust regulatory frameworks to ensure water quality and safety.

Safe Drinking Water Act (SDWA)

The SDWA, passed in 1974, empowers the EPA to set and enforce general standards for drinking water quality. It requires public water systems to regularly monitor and report on water quality to ensure the delivery of safe drinking water to the public. Under the SDWA, many compliance standards have been put into place, including, for example, the Lead and Copper Rule.

Clean Water Act (CWA)

The CWA, enacted in 1972, aims to protect and restore water quality in the United States. Its goal is to regulate the discharge of pollutants into surface waters and establishes water quality standards. Under the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) program requires permits for industrial discharges.

National Primary Drinking Water Regulations (NPDWRs)

NPDWRs are legally enforceable standards established under the SDWA. They specify maximum contaminant levels (MCLs) and treatment techniques for various waterborne contaminants. Monitoring is a crucial component of ensuring compliance with these regulations.

Technology’s Role in Water Quality Monitoring

Traditionally, water quality monitoring was an expensive and time-consuming endeavor. Monitoring itself was prone to human error and required manual sampling. Data analysis, undertaken by third-party labs, could slow down man time to intervention, and water operators would often have to react to older, sometimes out-of-date KPIs.

Technology has significantly changed how organizations can now monitor their water. With digital interventions, water operators can act faster to protect water resources better while saving time and money. New technology applications in water quality monitoring include:

  • Automation. This can help remove human intervention during water testing and analysis. 
  • IoT. Using sensors, water operators can more quickly detect leaks and environmental factors (like temperature changes).
  • AI and Machine Learning. Leveraging AI and ML can help water operators move from being reactionary to prescriptive in terms of water treatment and equipment maintenance.
  • Cloud Computing. Data silos can be removed by pulling all water-related data into the cloud. This centralization helps with both the parsing of and access to essential data that can help manage water resources.

How KETOS Leverages Technology to Streamline Water Quality Monitoring

KETOS is at the forefront of modernizing water quality monitoring by offering innovative solutions that address the challenges faced by various industries. Using on-site hardware and innovative software that can capture and analyze 30+ water parameters, KETOS offers water operators:

Real-Time Data. KETOS provides real-time data for immediate detection of deviations from water quality standards, enabling rapid responses and minimizing risks to the public’s health and the overall health of the environment.

Remote Monitoring. While monitoring happens on-site, that data is transferred in real-time to the water operator so that they gain access to real-time results. These results are conveniently transmitted to an operator’s phone, tablet, or laptop so they can check their results – even if they are off-site. 

Data Analytics

KETOS employs advanced data analytics to provide actionable insights. Its software can predict potential water quality issues, allowing proactive measures to prevent non-compliance.

Compliance Reporting

KETOS simplifies compliance reporting by automating data collection and analysis. This reduces the administrative burden on municipalities and industrial facilities, ensuring they can efficiently meet regulatory requirements.

How Various Industries Leverage KETOS

KETOS is versatile and adaptable, making it suitable for various industries. For example, KETOS technology is applicable to: 


Farmers in both open field and indoor ag can use KETOS to monitor water quality, ensuring that the water used for crops is free from contaminants while containing the right balance of chemicals and nutrients. This not only enhances crop yield but also reduces the environmental impact of agriculture.


Industrial facilities can deploy KETOS to continuously monitor effluent quality, helping them meet NPDES permit requirements and avoid costly compliance violations. It can also monitor influent and water quality at various stages of the manufacturing process where water quality may dictate product integrity – especially in instances of food or beverage manufacturing or pharmaceuticals.
