Who We Serve

Pace® has been helping communities, businesses, and industries meet drinking water, groundwater, surface water, and wastewater regulatory requirements for more than three decades.

Our Water and Liquid testing services help community leaders monitor water quality and provide reliable data for informed decision-making and effective management of water resources.


Our comprehensive testing and water and liquid analysis services identify potential contaminants in wastewater discharge in support of regulatory compliance, risk mitigation, and environmental stewardship.


Our water testing services also help professionals in industries such as solid waste management and wastewater treatment make informed decisions and ensure compliance with environmental regulations.

Facilitating Regulatory Compliance

As contaminant concerns grow, keeping up with changing water quality regulations is more challenging than ever.

Drinking Water

In the U.S., the Safe Drinking Water Act (SDWA) sets mandatory standards for the maximum contaminant levels (MCLs) of various pollutants, including bacteria, viruses, chemicals, and radionuclides. These standards are referred to as the National Primary Drinking Water Regulations (NPDWR). States may also set their own standards as long as they meet or exceed federal standards.

The Unregulated Contaminant Monitoring Rule (UCMR) is another component of the SDWA, which requires public water systems to monitor and report the presence of specific unregulated contaminants. The EPA and state agencies use this data to determine whether future regulation is necessary.

The protection of groundwater resources in the U.S. is governed by various federal and state regulations. For example, the Safe Drinking Water Act (SDWA) Underground Injection Control (UIC) program aims to prevent the contamination of underground sources of drinking water by regulating the construction, operation, and closure of injection wells. The Resource Conservation and Recovery Act (RCRA) is another program which focuses on the management of hazardous waste to prevent the contamination of groundwater resources. As with drinking water, states may also set their own standards for groundwater quality, but they must meet or exceed federal standards.

Surface Water

Surface water quality in the U.S. is primarily regulated through the Clean Water Act (CWA). The CWA requires the EPA to develop water quality criteria for surface waters that accurately reflect the latest scientific knowledge regarding the impact of specific pollutants on human health and the environment. These criteria are then used by states and communities to establish water quality standards for bodies of water under their jurisdiction.

The CWA also regulates the discharge of pollutants into surface waters through the National Pollutant Discharge Elimination System (NPDES) permitting program. Additionally, the EPA has developed the Surface Water Treatment Rules (SWTRs) under the Safe Drinking Water Act (SDWA) to improve drinking water quality and protect against disease-causing pathogens and contaminants that can form during drinking water treatment.

Wastewater in the U.S. is primarily regulated under the Clean Water Act (CWA), which establishes the basic structure for regulating discharges of pollutants into the waters of the United States (WOTUS). Under the CWA's National Pollutant Discharge Elimination System (NPDES), program permits are issued to facilities, specifying the types and amounts of pollutants that can be discharged and the required monitoring and reporting to ensure compliance. Wastewater treatment plants, industrial facilities, and some stormwater discharges are among the entities regulated by the NPDES program. The EPA works with state, tribal, and local governments to implement and enforce the CWA and NPDES regulations.
