Our Services

Our staff at LEC are ready to utilize their experience to maintain your environmental compliance. Ensuring that reports are complete and made on time.

Water/Wastewater Compliance Management

Starting at $700/month

Surprised by a non-compliance letter — even when your samples were in order?

For many water and wastewater utilities, the problem isn’t missed sampling, but rather it’s paperwork delays, lab reporting errors, or third-party data submissions falling through the cracks. Even when your chemistry results are fully compliant, a late or missing report can still trigger a violation notice.

At Limestone Environmental Consultants, we actively monitor the full chain of compliance — from sample collection to regulatory reporting — ensuring that nothing gets lost between your utility, the lab, and the regulators.

Our Compliance Management Packages include:

  • Comprehensive oversight of compliance data and reporting

  • State and EPA regulatory submissions

  • Direct coordination with laboratories and regulatory agencies

  • Permitting support and assistance

  • Inspection preparation and document review

With LEC managing your compliance program, you stay ahead of deadlines, reduce administrative burden, and minimize your risk of costly violations.

Iron and Manganese Reduction

Starting at $1,500/month

Dirty water complaints? Red or black staining? Chlorine drop-offs? DBP formation?

Iron and manganese buildup in distribution systems often hides in plain sight — until customers start noticing discolored water, staining in appliances, or unusual taste and odor issues. These buildups form plaques that harbor iron bacteria and other contaminants, creating long-term operational problems.

As chlorine interacts with these deposits, residual disinfectant levels drop, contributing to increased disinfection byproduct (DBP) formation and further impacting water quality.

LEC’s Iron & Manganese Service includes:

  • Strategic sampling at multiple points throughout your distribution system

  • Identification of iron and manganese loading patterns

  • Evaluation of chlorine depletion zones

  • Targeted treatment recommendations to address dirty water complaints and prevent plaque buildup

  • Practical, field-tested solutions that protect both water quality and infrastructure

By addressing these underlying issues, LEC helps your utility reduce customer complaints, improve regulatory compliance, and extend the life of your system.

PFAS Pilot Testing

Starting at $1,500/month

Take the guesswork out of PFAS treatment selection.

PFAS compliance presents a major challenge for utilities and with multiple treatment options available, selecting the right solution for your specific water system requires real data.

At LEC, we manage column pilot studies to help utilities evaluate treatment media performance before full-scale implementation. Our team works closely with established partners such as Calgon, Evoqua, and AqueousVets to install and operate pilot testing units on-site.

Popular media options include:

  • Granular Activated Carbon (GAC)

  • Ion Exchange (IX) Resins

  • CETCO Clay Media

LEC’s PFAS Pilot Testing services include:

  • Pilot study design and vendor coordination

  • Installation oversight of pilot treatment systems

  • Regular sampling and laboratory coordination

  • Data analysis and reporting presentations

  • Routine maintenance and system adjustments throughout the pilot period

  • Final recommendation based on pilot data and system-specific performance

At the conclusion of your pilot study, you’ll have clear, defensible data to select the most cost-effective, regulatory-compliant treatment solution for your system.
