Impact of Wastewater on the Environment and Health Impaired water quality (pollution of beaches, rivers, groundwater) Disease from polluted water and contaminated shellfish which may be consumed by humans Fish kills Eutrophication which results in excessive plant growth which can harm spawning grounds and become toxic to aquatic organisms 6 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Legislative Framework Natural Resources Conservation Authority Act, 1991 Natural Resources Conservation (Wastewater and Sludge) Regulations, 2013 7 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Why Regulations for wastewater and sludge? Raw and poorly treated septage, sludge, domestic and industrial waste entering gullies, streams and coastal areas Inadequately designed and malfunctioning sewage treatment systems Low capacity among operators of sewage treatment plants and in government Failure of voluntary compliance in the sector, and Cost to design, operate and maintain infrastructure 8 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency

Re-use of Wastewater Existing licensed facilities re-use treated effluent for irrigation Benefit from discount on discharge fees Majority of facilities that re-use effluent are in the hotel sector 26 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Re-use of Wastewater (contd) ISSUES: i. How can we increase re-use? ii. Do we have the data to support the push for re-use in light of CECs? iii. Cannot re-use effluent that does not meet the standards iv. Buy in from general public 27 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) Chemicals that are being discovered in water that previously had not been detected or are being detected at levels that may be significantly different than expected. Pose a risk to human health and the environment as a result of their presence, frequency of occurrence, or because their source may be unknown. 28 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont d) Q: How do CECs get into wastewater? A: From the use of pharmaceuticals and personal care products (PCPs) 29 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont d) Examples of CECs Polybrominated diphenyl ethers (PBDEs) Perfluorinated compounds (PFCs) Widely distributed and persistent in the environment. Both accumulate in human tissue or blood, and are associated with health effects including endocrine disruption. 30 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Chemicals in Wastewater: Contaminants of Emerging Concern (CECs) (cont d) WWSR promotes re-use (S. 45) Re-use necessary to meet current and future demands ISSUES: i. What are the CECs in our wastewater? ii. What impact will these have on our environment and health with increased re-use? 31 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Economic Valuation in Wastewater Management ISSUES Currently not being done in Jamaica In general, economic valuation usually not done because of inadequate property rights, presence of externalities and lack of perfect information (Hernandez-Sancho, et al , 2010) What is needed to start carrying out economic valuation in Wastewater Management Reference: Hernandez-Sancho, F., Molinos-Senante, M. and Sala-Garrido (2010) Economic valuation of environmental benefits from wastewater treatment processes: An empirical approach for Spain. Science of the Total Environment, 402 (4) pp. 953-957 32 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
Financing Wastewater Management ISSUES: i. Funding for maintenance of plants - critical ii. Funding for capacity building (both regulated and regulator) iii. Inadequate resources available to give effective oversight (from the regulator standpoint) iv. Obligation of government to ensure a healthy environment for citizens. v. Use of effluent discharge fees to augment. Timeline for when this will become feasible. 33 Managing and protecting Jamaica's land, wood and water National Environment and Planning Agency
