What is a NEMA Environmental Audit?
A NEMA environmental audit is a systematic, documented assessment of an existing borehole's compliance with environmental laws, regulations, and the commitments made during the Environmental Impact Assessment (EIA) process. It evaluates the borehole's construction, operation, water quality, waste management practices, and its impact on the surrounding environment.
The audit is conducted by a NEMA-registered environmental auditor who inspects the site, reviews records, tests water quality, and produces a detailed report with findings and recommendations. The audit report is submitted to NEMA for review and approval.
Unlike an EIA, which is conducted before a project begins, an environmental audit is conducted after the borehole is operational. It verifies that the borehole is being operated in an environmentally responsible manner and identifies any areas where improvements are needed.
Why are Environmental Audits Required for Existing Boreholes?
Environmental audits serve several critical purposes:
- Legal compliance – under the Environmental Management and Coordination Act (EMCA) 1999, all facilities with potential environmental impacts, including boreholes, are required to undergo periodic environmental audits.
- Protecting groundwater resources – audits help ensure that boreholes are not contaminating groundwater or depleting aquifers unsustainably.
- Identifying non-compliance – audits reveal issues such as poor construction, inadequate grouting, or contamination risks that need to be addressed.
- Supporting permit renewals – the Water Resources Authority (WRA) may require an environmental audit as part of the water use permit renewal process.
- Liability protection – demonstrating compliance through an audit can protect you from legal action or fines.
- Corporate responsibility – for businesses, environmental audits demonstrate a commitment to environmental stewardship.
Key Fact: NEMA requires environmental audits for all facilities listed under the Environmental Management and Coordination (Audit) Regulations, 2011. Boreholes are included in this list.
The Legal Framework
The requirement for environmental audits is established under several legal instruments:
| Legislation/Regulation | Requirement |
|---|---|
| Environmental Management and Coordination Act (EMCA) 1999 | Provides the legal basis for environmental audits and requires facilities with significant environmental impacts to be audited. |
| Environmental Management and Coordination (Audit) Regulations, 2011 | Specifies the requirements for environmental audits, including the qualifications of auditors, the audit process, and reporting standards. |
| Environmental Management and Coordination (Waste Management) Regulations, 2006 | Sets standards for waste management, including disposal of drilling mud, cuttings, and other borehole-related waste. |
| Water Act 2016 | Requires that water abstraction be conducted in an environmentally sustainable manner, which is assessed through audits. |
Failure to comply with these regulations can result in fines, legal action, and closure of the borehole.
What Does a NEMA Environmental Audit Involve?
A typical NEMA environmental audit for an existing borehole includes the following steps:
- Step 1: Scoping and planning – the auditor reviews the borehole's history, permits, and previous environmental assessments to plan the audit.
- Step 2: Site visit and inspection – the auditor visits the site to inspect the borehole, pump house, storage tanks, and surrounding area. The inspection covers construction standards, sanitary seals, grouting, and waste management practices.
- Step 3: Water quality testing – samples are collected and sent to a certified laboratory to test for parameters such as pH, turbidity, heavy metals, nitrates, and bacteriological contamination.
- Step 4: Records review – the auditor reviews abstraction records, maintenance logs, and any previous environmental reports.
- Step 5: Interview with operators – discussions with the borehole operator or owner to understand operational practices and any concerns.
- Step 6: Report preparation – a detailed audit report is prepared, summarising findings, identifying non-compliance issues, and proposing corrective actions.
- Step 7: Action plan – the auditor develops an action plan with timelines for addressing any non-compliance issues.
- Step 8: NEMA submission – the audit report is submitted to NEMA for review and approval. NEMA may request additional information or require follow-up audits.
- Step 9: Follow-up – once corrective actions are implemented, the auditor may conduct a follow-up visit to verify compliance.
The entire process typically takes 2–4 weeks, depending on the complexity of the borehole and the accessibility of the site.
Common Findings in Borehole Environmental Audits
Environmental audits often reveal common issues that need to be addressed. Here are the most frequent findings:
| Issue | Typical Finding | Recommended Action |
|---|---|---|
| Inadequate sanitary seal | Missing or damaged concrete pad, insufficient grouting | Install or repair sanitary seal, regrout the annulus |
| Poor borehole construction | Incorrect casing depth, damaged screen, lack of gravel pack | Conduct borehole rehabilitation or repair |
| Lack of permits | No WRA water permit or NEMA EIA approval | Apply for the required permits retroactively |
| Water quality issues | Elevated iron, manganese, or bacterial contamination | Install treatment system, conduct disinfection |
| Waste management | Improper disposal of drilling mud, cuttings, or wastewater | Implement proper waste management practices |
| Lack of abstraction records | No records of water volume abstracted | Install a flow meter and maintain abstraction logs |
| Surface water contamination risk | Borehead located in low-lying area prone to flooding | Raise the borehead, improve drainage |
| Security concerns | No fencing or locking of borehead | Install security fencing and locking mechanism |
The audit report provides a clear roadmap for addressing these issues, prioritising them based on environmental risk and regulatory requirements.
Cost of a NEMA Environmental Audit
The cost of a NEMA environmental audit depends on several factors, including the depth of the borehole, the complexity of the site, and the scope of the audit. Typical costs are:
| Service | Estimated Cost (KES) | Notes |
|---|---|---|
| Audit planning and scoping | 10,000 – 25,000 | Preliminary work |
| Site visit and inspection | 15,000 – 40,000 | Includes travel and site assessment |
| Water quality testing | 10,000 – 30,000 | Depends on the number of parameters |
| Report preparation | 15,000 – 35,000 | Detailed report with findings and recommendations |
| NEMA filing fee | 5,000 – 10,000 | NEMA application and processing fee |
| Total estimated cost | 50,000 – 150,000 | Varies by complexity |
While the cost may seem significant, it is a small investment compared to the potential fines and legal costs of non-compliance. It also provides valuable information for managing your borehole effectively.
Consequences of Non-Compliance
Failure to conduct a required environmental audit or to address identified non-compliance issues can have serious consequences:
- Fines and penalties – NEMA can impose fines under EMCA for non-compliance. Fines can range from KES 50,000 to KES 1,000,000 depending on the severity of the violation.
- Legal action – in serious cases, NEMA or the WRA may initiate prosecution, leading to fines and even imprisonment.
- Borehole closure – the WRA or NEMA can order the closure of the borehole until compliance is achieved. This can be a major disruption to your water supply.
- Permit revocation – the WRA can revoke your water use permit, making it illegal to abstract water.
- Liability for damages – if your borehole causes environmental damage (e.g., contamination of neighbouring boreholes), you may be liable for civil damages.
- Reputational damage – for businesses, non-compliance can damage your reputation and affect relationships with customers, investors, and regulators.
Warning: NEMA and WRA have increased enforcement in recent years. Ignorance of the law is not a defence, and non-compliance is treated seriously.
Environmental Audit vs. EIA: What's the Difference?
Many borehole owners confuse environmental audits with Environmental Impact Assessments (EIAs). While both are important, they serve different purposes:
| Feature | Environmental Impact Assessment (EIA) | Environmental Audit |
|---|---|---|
| Timing | Conducted before a project begins | Conducted on existing, operational boreholes |
| Purpose | Predict and mitigate potential environmental impacts | Assess actual environmental performance and compliance |
| Focus | Future impacts and proposed mitigation | Actual impacts and compliance with regulations |
| Output | EIA report with predicted impacts and mitigation measures | Audit report with findings, non-compliance issues, and corrective actions |
| Frequency | Once per project (before start) | Periodic (typically every 3–5 years) |
| Regulatory basis | EMCA 1999, Section 58 | EMCA 1999, Environmental Audit Regulations |
If you drilled your borehole without an EIA, you may be required to conduct an environmental audit to regularise its status. This is often referred to as a "retrospective EIA" or "environmental audit."
